Why Your Excavator Is Losing Hydraulic Power

Wed, 08 Apr 2026 19:46:41 GMT

A loss of hydraulic power in an excavator can suddenly halt a job, erode productivity, and lead to costly downtime. Understanding the primary causes—fluid condition, component wear, system contamination, and control issues—helps owners prioritize diagnostics and communicate effectively with service technicians. Below are the most common reasons hydraulic power fades, how to recognize symptoms, and when to involve professional service.

What Causes Sudden Loss of Hydraulic Power in Excavators?

Sudden or progressive power loss usually stems from reduced system pressure or restricted flow. Key causes include worn pump components, internal valve leaks, and insufficient fluid volume. A slipping or failing hydraulic pump will not develop adequate pressure; internal leakage within control valves or actuators reduces force at the bucket or boom. Low fluid levels due to leaks or improper maintenance also cause cavitation and reduced performance. Symptoms to watch for include slow or weak actuator movement, erratic operation, and audible whining or cavitation from the pump area.

How Does Hydraulic Fluid Condition Affect Performance?

Contaminated or degraded fluid directly impairs system efficiency. Contaminants such as water, metal particles, and dirt increase wear and can clog fine control passages. Oxidized or thermally degraded oil loses lubricity and pressure-stable characteristics, increasing internal leakage and reducing component life. Viscosity that is out of specification due to incorrect fluid or temperature extremes can also restrict flow and pressure. Regular fluid analysis provides early warning signs; lab results showing elevated wear metals, water content, or viscosity deviation indicate imminent component issues.

What Are the Most Common Component Failures That Cause Power Loss?

Hydraulic Pump Wear: Internal clearances increase with use, reducing maximum pressure and flow; symptoms include whining, heat, and slow cycle times.

Control Valve Spools or Seats: Internal leaks around spool valves reduce actuator force and cause erratic movement; this may follow contamination or wear.

Cylinder Rod or Seal Damage: External leaks reduce system volume, and internal seal wear causes bypassing, leading to weaker extension/retraction force.

Relief Valve Maladjustment or Failure: A relief valve that is stuck or set too low releases pressure prematurely, making the system feel weak even with good pump output.

Hoses and Fittings with Internal Collapse: Collapsed hose liners restrict flow under load, producing intermittent power loss and pressure spikes.

Contamination in Filtration Elements: Blocked filters cause restricted flow to critical circuits, raising temperature and accelerating wear.

Heat-Related Issues: Overheating breaks down fluid and increases internal leakage rates across pumps and valves.

When Should You Call a Professional Hydraulic Technician?

If you haven’t had a basic inspection (visual leaks, fluid level, filter change history) in a while, call a qualified technician. Professionals have pressure gauges, flow meters, and the experience to isolate pump, valve, or actuator problems. They can perform fluid analysis, measure pump output, and run diagnostic pressure tests that identify internal leakage or relief valve faults. Improper troubleshooting or incorrect DIY adjustments can worsen damage; relying on trained service personnel typically prevents mistakes and higher repair costs later.

How Can Owners Prepare for Faster Repair and Less Downtime?

Document machine hours, recent maintenance, and any unusual symptoms (noises, overheating, slow cycles). Keep records of fluid changes and filter replacements, and have serial/model numbers ready for parts ordering. While some minor maintenance is routine, remember that attempting advanced hydraulic repairs without proper tools and diagnostics often leads to misdiagnosis and increased expense. Prompt professional evaluation when symptoms begin will minimize downtime and protect the machine’s long-term value.

What Is a Hydraulic Cylinder?

Sat, 07 Mar 2026 02:37:54 GMT

Hydraulic cylinders are fundamental components in modern machinery, translating fluid power into linear mechanical force and motion. Common across industries—from construction and agriculture to manufacturing and aerospace—these devices enable lifting, pushing, pulling, and precise positioning under heavy loads. Understanding what a hydraulic cylinder is, how it works, and where it’s used helps decision-makers specify the right unit for performance, reliability, and safety.

What Is the Basic Design of a Hydraulic Cylinder?

A hydraulic cylinder consists of a cylindrical barrel, a piston fitted with seals, a piston rod, and end caps (head and cap). Pressurized hydraulic fluid enters the barrel, exerting force on the piston to produce linear motion. The rod transfers that motion to the external mechanism. Seals prevent fluid leakage and maintain pressure, while materials and tolerances determine durability and suitability for specific operating conditions.

How Does Hydraulic Cylinder Operation Translate to Force and Motion?

Hydraulic cylinders follow Pascal’s principle: pressure applied to a confined fluid is transmitted equally in all directions. Force output equals fluid pressure multiplied by piston area. Engineers select bore size, stroke length, and operating pressure based on required force, speed, and space constraints. Single-rod, double-rod, and telescopic cylinder designs adapt the basic principle to achieve bi-directional force, compact stowed length, or extended reach.

What Are Common Hydraulic Cylinder Types and Applications?

Tie-rod Cylinders: Economical and easy to service; common in industrial presses and material handling.

Welded-Barrel Cylinders: Compact and robust; used in mobile equipment like excavators and loaders.

Telescopic Cylinders: Multi-stage extension for long strokes in confined spaces (e.g., dump trucks).

Double-Acting Cylinders: Apply force in both directions using controlled fluid on both sides of the piston.

Mill-Type Cylinders: Heavy-duty, large-bore units for steel mills and marine applications.

Steering and Rotary Actuators: Specialized cylinders and units for vehicle steering and rotary motion.

What Performance Factors and Specifications Matter for Selection?

Bore Size and Rod Diameter: Determine force capacity and buckling resistance.

Stroke Length: Defines maximum travel distance.

Operating Pressure and Flow: Influence speed and power; system pumps and valves must match cylinder specifications.

Mounting Style: Clevis, flange, trunnion, and foot mounts affect alignment, load distribution, and installation complexity.

Seal Material and Type: Critical for fluid compatibility, temperature range, and resistance to contamination.

Cycle Life and Maintenance Intervals: Drive decisions on material, coating, and protection against environmental and debris exposure.

How Do Reliability, Safety, and Maintenance Impact Hydraulic Cylinder Use?

Routine inspections, proper filtration, and correct fluid selection prolong service life and prevent catastrophic failures. Contamination and seal wear are primary causes of leakage and reduced performance; monitoring fluid cleanliness and addressing system overheating are essential. In critical applications, redundant systems, pressure relief devices, and load-holding valves enhance safety. Improper repair or ad-hoc fixes can accelerate wear and increase long-term costs.

Which Industry Trends and Innovations Are Shaping Hydraulic Cylinder Design?

Lightweight Materials: Advanced alloys and composites reduce weight while preserving strength for mobile machinery.

Smart Sensors and Condition Monitoring: Embedded sensors monitor pressure, temperature, and position to enable predictive maintenance.

Improved Sealing Technologies: New polymers and geometries extend seal life under extreme conditions.

Energy Efficiency: Systems that recover or reduce wasted hydraulic energy lower operating costs and emissions.

What Should Decision Makers Know About Hydraulic Cylinders?

Hydraulic cylinders convert fluid pressure into linear force and motion with high power density.

Selection depends on bore, stroke, pressure, mounting, and seal compatibility.

Common types include tie-rod, welded-barrel, telescopic, and mill-type cylinders for a range of applications.

Reliability hinges on cleanliness, correct fluid, appropriate sealing, and proper system design.

Innovations focus on materials, sensing, sealing, and energy efficiency to meet modern demands.

Choosing the right hydraulic cylinder requires aligning application demands with mechanical specifications and maintenance practices to ensure safe, efficient, and long-lasting performance.

What Are Some Common Issues With Hydraulic Cylinders?

External leaks: Seals or fittings worn or damaged; visible fluid, reduced system pressure.

Internal leakage (blow-by): Worn piston seals or scoring; cylinder drifts or won’t hold position.

Seal failure: Age, contamination, heat, or improper installation; causes leaks and loss of force.

Contaminated fluid: Dirt, metal particles, or water; accelerates wear, causes scoring, and damages seals.

Rod damage (nicks, scratches, scoring): Debris or mishandling; leads to seal failure and leaks.

Corrosion: Moisture in fluid or environmental exposure; pitting on rod or cylinder tube, accelerated seal wear.

Misalignment: Poor mounting or shaft offset; uneven wear, bent rods, accelerated seal/guide failure.

Bent or twisted rod: Shock loads or misalignment; binding, uneven extension, permanent damage.

Overheating: Excessive cycle rate, low fluid level, or fluid contamination; softens seals, reduces fluid viscosity.

Cavitation: Rapid pressure drops creating vapor bubbles; noisy operation, pitted surfaces, poor performance.

Pressure spikes/shock: Sudden loads or valve faults; shortens component life, can cause seal extrusion or burst hoses.

Slow or uneven movement: Air in the system, clogged ports/filters, internal leakage, or worn pump/components.

Worn guide bushings or bearings: Side loads or contamination; rod chatter, scoring, and inaccurate travel.

Hose or fitting failure: Age, abrasion, or improper routing; sudden leaks and loss of function.

Incorrect fluid (viscosity/additives): Wrong lubricant properties damage seals and reduce efficiency.

Improper installation or mounting hardware: Wrong pins, torque, or geometry; premature failures and unsafe operation.

Regular fluid maintenance, proper filtration, correct alignment and installation, and routine inspections prevent most of these problems.

5 Common Causes of Hydraulic Cylinder Leaks

Wed, 18 Feb 2026 22:10:00 GMT

Hydraulic cylinders convert fluid pressure into powerful linear motion, enabling heavy lifting, pushing, and precise control in machinery. They are widely used in construction, manufacturing, agriculture, and transportation equipment, providing strength, reliability, and efficiency for tasks that require consistent force and smooth mechanical operation.

When a hydraulic cylinder is leaking, it can put a wrench in the works. Here are five common causes of hydraulic cylinder leaks:

1. Worn or Damaged Seals

Seals are designed to contain pressurized fluid while allowing smooth piston movement. Over time, they degrade due to heat, friction, and chemical exposure. Even minor imperfections in a seal can allow hydraulic fluid to escape.

Common contributors include:

Normal wear from continuous operation
Exposure to extreme temperatures
Fluid contamination causing abrasion
Incorrect seal material for the application

Once seals lose elasticity or develop cracks, leakage becomes almost inevitable.

2. Scored or Pitted Cylinder Rod

The rod surface must be smooth and free of defects for seals to function correctly. When a rod is scratched, dented, or corroded, it creates pathways that allow fluid to bypass the seal.

Rod damage often results from:

Dirt or grit entering the system
Improper storage or handling
Exposure to moisture and corrosive environments
Mechanical impact during operation

Even microscopic imperfections can cause persistent leaks because seals are designed to work against a perfectly smooth surface.

3. Contaminated Hydraulic Fluid

Hydraulic systems rely on clean fluid to function correctly. When contaminants such as dust, metal shavings, or water enter the system, they act as abrasives within the cylinder. This damages seals and internal surfaces, accelerating wear and increasing the likelihood of leaks.

Contamination can cause:

Premature seal failure
Increased internal friction
Corrosion of metal components
Reduced system efficiency

In many cases, a leaking cylinder is a symptom of a larger contamination issue elsewhere in the system.

4. Excessive System Pressure

Hydraulic cylinders are built to operate within specific pressure ranges. When pressure exceeds those limits—whether due to system misconfiguration or load changes—it places additional stress on seals and internal components.

High pressure can lead to:

Seal extrusion or blowout
Deformation of internal parts
Cracking of cylinder housings
Catastrophic leakage

Repeated pressure spikes are especially harmful because they weaken seals gradually before failure becomes visible.

5. Misalignment or Side Loading

Hydraulic cylinders are designed to move in a straight line. When they are installed incorrectly or subjected to uneven forces, side loading occurs. This puts abnormal stress on the rod and seals, increasing friction and wear.

Misalignment may result from:

Poor mounting geometry
Structural frame movement
Worn bearings or joints
Improper load distribution

Over time, this leads to uneven seal wear and distorted components, both of which contribute to leakage.

Why These Leaks Matter

Hydraulic leaks are more than just messy. They can compromise safety, reduce machine precision, and raise operating costs. A slow leak may seem minor at first, but it often points to internal damage that worsens if left unaddressed. In high-pressure systems, even a slight loss of fluid can lead to unstable or unpredictable operation.

From an operational standpoint, leaks also affect efficiency. Systems must work harder to maintain pressure, increasing energy consumption and accelerating component fatigue.

The Bigger Picture

Most hydraulic cylinder leaks don’t stem from a single failure. Instead, they develop from a combination of wear, contamination, and mechanical stress. Recognizing the root cause helps distinguish between surface-level problems and signs of deeper system issues.

By understanding these common causes—worn seals, rod damage, contaminated fluid, excessive pressure, and misalignment—you can better assess the impact of a leak on your equipment. In many cases, the leak itself is just the visible symptom of internal strain or environmental exposure.

Hydraulic cylinders are designed for durability, but like all precision components, they depend on proper conditions to perform reliably. Knowing why leaks happen makes it easier to take informed action when they appear—and to appreciate just how critical these components are to modern machinery.

As long as the cylinder is not replaced, but other components are, this qualifies as a cylinder repair.

Cylinder Rebuild

If the issues cannot be fixed with a repair, the cylinder will need a rebuild, which is exactly what it sounds like. The technicians will take apart the cylinder and use the Original Equipment Manufacturer (OEM) parts to recreate a cylinder that works as well as it did when you first purchased the equipment.

Should I Repair Or Rebuild?

Many factors go into this decision. Of course, you should always consult an expert but it depends on the following criteria.

How Old Is Your Machine?

Newer cylinders will likely be fine with a repair while an older cylinder may require a rebuild. Older cylinders tend to break down due to deterioration.

What’s Your Budget?

Repairs are less costly than rebuilds so they’re the best option if your cash flow is running short, but you need your cylinder running well. It’s worth mentioning that repairs only last so long so if you need a rebuild it will save you money to have the rebuild in the long run.

Quality of Parts

The parts that are used for repairs are not required to be OEM parts, and lesser quality parts can lead to damage or poor performance. Rebuilds require OEM-approved parts that are set specifically to your machine.

A Guide to the Common Types of Hydraulic Pumps

Tue, 05 Sep 2023 20:28:26 GMT

In the world of industrial machinery, hydraulic systems power everything from heavy construction tools to precise manufacturing processes. Hydraulic pumps are at the heart of how these devices work.

If you want to use hydraulic systems to their fullest potential, you must understand how hydraulic pumps work. Here is a guide to the complicated world of hydraulic pumps, breaking down the features, functions, and uses of the most popular types that keep industries moving forward.

Piston Pumps

Piston pumps use a cylinder block with pistons that move back and forth to pull oil from the input port and push it out the exit. There are both fixed-displacement and variable-displacement pumps. The amount of the pump's cylinders determines how far the piston moves.

When working pressures need to be high, piston pumps are better than other types of pumps because they can handle higher pressures. Because piston pumps can handle such a wide range of pressures, they can be set to very high pressures without losing performance. The main problems with piston pumps are that they are heavy, need maintenance, and are expensive.

Both fixed-displacement and variable-displacement radial piston pumps have a rotor hub with a set of pistons in a circle around them. As the rotor turns in the pump body, it pushes the pistons in and out of the cylinders. This pulls hydraulic fluid into the cylinder cavity and pushes it out of the cylinder cavity.

Gear Pumps

Gear pumps are a type of positive displacement or fixed displacement hydraulic pump that move fluid by connecting gears that turn in different directions. They are used in systems with no closed loops. They are the most common type of truck-mounted hydraulic devices because they are cheap, reliable, easy to maintain, and don't get contaminated.

Gear pumps are measured by how much pressure they can handle, how many cubic inches they can move, and how quickly they can be turned on. The gears trap oil between their teeth and move it around the gear cavity through their meshing, ultimately forcing it out of the outlet port. Thrust plates hide small amounts of oil under pressure that push against the gear ends to make them work better.

The most popular types are external gear pumps and internal gear pumps. Two spur gears outside the pump work together to move liquids. However, internal gear pumps move fluid using inner and outer gears and a crescent-shaped section.

As the two gears turn, they create suction and release zones that move the axis of the outer gear away from the axis of the inner gear. The oil caught between the gears on the pump's suction side flows through the bearings.

Vane Pumps

Hydraulic vane pumps increase pressure by pushing fluid past rotating vanes on a rotor that moves in a zigzag pattern inside the pump's case. Turning the rotor closes the space between the pump casing and the vanes. This forces fluid out of the exit.

By moving the rotor's spinning axis in relation to the pump's housing, the amount of fluid that comes out of the pump can be changed. When the axes of the rotor and the container are the same, no air moves.

Vane pumps are widely used in the car industry because they can start up independently, have a high volumetric and overall efficiency, and keep a constant flow rate at various pressures. Plus, the vanes are easy to switch out, so they can handle liquids containing air and gas while still being small and light.

However, vane pumps shouldn't be used with abrasive fluids because they need good seals and filtration systems to keep them safe. They might also not work well in extreme situations, like when there is a lot of pressure or the fluid is thick. Also, you need relief valves to keep the pump from getting damaged by a sudden stop in supply.

4 Common Types of Hydraulic Cylinders

Wed, 09 Aug 2023 19:45:55 GMT

Hydraulic cylinders are indispensable tools in heavy machinery, making many industrial operations possible. Technological advancements in hydraulics have led to the development of various hydraulic cylinder types, each with unique features suited to specific applications.

Understanding the different types of hydraulic cylinders available can help you choose the right one for your specific needs and optimize the performance of your hydraulic systems. Here are four popular types of hydraulic cylinders, along with their unique designs and functionalities.

1. Single-Acting Cylinders

Single-acting hydraulic cylinders feature a single fluid entry and exit port to facilitate their operation. The sealed head that rests on the piston shaft allows the piston's force to be applied solely in one direction.

Force is applied via fluid injection through the cylinder's only port at its front end. This pushes the plunger up and out of the barrel. When the pressure decreases, the piston will return to its previous position since the internal spring is sealed off from the fluid. When there is no other way to generate a return force, the spring can do so independently.

The benefits of single-acting cylinders include their small size, ease of use, and low price. They are dependable in their purpose and are simple to keep in working order. Single-acting cylinders featuring retractable springs have a shorter lifespan than those without because the springs wear out and break. Long-term contact with corrosive fluids can potentially cause damage.

2. Double-Acting Cylinders

Double-acting hydraulic cylinders can apply force via hydraulic pressure in both the forward and reverse directions. They comprise a pump supplying hydraulic flow in either direction through two ports at the cylinder's head and rod end.

These parts help double-acting cylinders to rapidly and precisely extend and retract the plunger. This is helpful in any situation where pushing or pulling forces are needed, but especially in precise situations.

Standard and non-differential or double-rod cylinders are the two most frequent varieties. Standard cylinders only have one rod that can pressurize in one direction, however non-differential cylinders feature two rods that execute opposing strokes.

Double-acting cylinders are advantageous because of their low cost, dependability, and low energy consumption. They're built to last and can withstand the power demands faced by equipment like ship motors and industrial furnaces, and their stroke measurements are easy to pinpoint. This aspect, combined with the double-acting cylinder's ram lip, which supports the rod during extension and retraction, makes it a versatile tool.

3. Telescopic Cylinders

Telescoping hydraulic cylinders are perfect for uses with limited accessible space because of their increased stroke and reach. As telescopic cylinders feature more than five stages of tubes nested inside each other, the width of each stage decreases, so the cylinder can move in and out to achieve a longer stroke.

Telescopic cylinders are widely employed to lift loads over a longer distance, and the load capability diminishes correspondingly with each cylinder extension. Manufacturers typically produce double-acting telescopic cylinders to order but cost significantly more than their standard counterparts.

4. Tie-Rod Cylinders

Each tie-rod hydraulic cylinder has a minimum of four tie rods that link the cylinder barrel, base, and head. Most manufacturers use high-strength threaded metal rods to assemble the cylinders, which allows for easier maintenance, repairs, and leak aversion. While four tie rods are typical for smaller diameter cylinders, as many as sixteen or twenty may be necessary for larger bore cylinders to sustain the cylinder's strength in operations generating significant forces.

Tie-rod cylinders, in contrast to more robust high-pressure cylinders, are more suited to applications that require lesser pressures, such as bulky lifting. This cylinder design allows for a full disassembly and rebuild. However, tie-rod cylinders are not always adaptable to specific uses.

4 Ways Hydraulic Fluid Can Get Contaminated

Mon, 10 Jul 2023 06:23:03 GMT

Hydraulic systems are widely used in various industries for efficient power transmission capabilities. Hydraulic systems rely on clean and uncontaminated hydraulic fluid to ensure optimal performance and longevity. However, even with the best maintenance practices, hydraulic fluid contamination can occur, leading to compromised system performance and potential damage.

By understanding these contamination sources, you can take proactive measures to prevent or address them, safeguarding the integrity and reliability of your hydraulic system. Here are the four primary ways hydraulic fluid can become contaminated.

1. Contamination During Production

Several processes and conditions can lead to contaminated hydraulic fluid being used in manufacturing. The purity of the fluid supplied by providers is the primary consideration. According to the ISO 4406 Cleanliness Code, the typical hydraulic fluid carries a cleanliness rating between 17/16/14 and 20/18/16, which is still better than most equipment manufacturers suggest. But these hydraulic fluids still lack sufficient purity for use in today's hydraulic systems.

Hydraulic fluid may get tainted at any point during the manufacturing process, including during processing and mixing. The introduction of pollutants into the fluid can result from incorrectly designed equipment, machinery, and tools.

Furthermore, dirt, dust, and debris can enter the hydraulic fluid without proper safety measures. Hydraulic fluid is also vulnerable to contamination from various sources, including leaks from other industrial processes.

Contamination that begins with the supplier from the fluid's production conditions are beyond the buyer's control. Thus, filter all fluids before they enter the hydraulic systems to prevent system inadequacies.

2. Contamination Built In

Welding slag, milling swarf, bits of Teflon tape, and too much sealant can all contribute to built-in hydraulic fluid contamination during assembly or maintenance. This contamination is notoriously difficult to detect and often leads to undesirable system behavior like fluid leakage or pressure decreases. Cleaning the hydraulic fluid beforehand is crucial for avoiding immediate and long-term damage to machinery.

Regular inspection and replacement of the filters can help prevent the accumulation of impurities in the hydraulic system, which can hasten the system's decline. Also, install system components with extreme caution to avoid introducing any of the above pollutants, such as bits of Teflon tape or too much sealant, into the system.

3. Contamination During Storage

When the hydraulic fluid gets subjected to weather changes, debris, dust, and humidity during storage, either because of breathing or improper sealing, the fluid becomes contaminated.

Incorrect sealing allows contaminants to enter the fluid because the container was not shut tightly or was left open. Breathing occurs when moisture enters the interior of a sealed, watertight plastic container due to temperature changes.

Always store hydraulic fluid in a sealed container at a constant temperature to prevent contamination from the storage environment. If you need to keep the container outside, lay it on its side to stop water from pooling on top of it. Temperature control is not the only solution since you should regularly check the integrity of the containers' seals.

When moving hydraulic fluid from one container to another, take special precautions to prevent fluid contamination. Thoroughly clean the storage containers before you pour the fluid into them.

4. Contamination During Fluid Transfer

The surrounding environment and the method of transmission might lead to hydraulic fluid contamination during transfer. Fluids can pick up dirt and moisture from the atmosphere if transported in an unsanitary setting. Failure to flush the system before introducing used or new fluid might also exacerbate contamination. Chemical interactions between different fluids can also taint the entire mixture.

Ensure there is no dust or debris in the area, and flush the whole system before you add hydraulic fluid to minimize the risk of contamination. Also, do not leave the fluid's cover off longer than necessary.

Hydraulic Lock: Overview, Causes, and Damage

Fri, 07 Jul 2023 14:40:55 GMT

A hydraulic lock is one of the worst problems that can happen to any hydraulic system. You can better protect your machines if you understand how hydraulic locks occur. Here is a highlight of the important information you need to protect your hydraulic systems.

Overview

A hydraulic lock, also called hydrolock or hydrostatic lock, occurs when a fluid enters the cylinders in a hydraulic system and limits their compression. Since most fluids cannot compress effectively, the excess liquid inside the cylinder causes the engine to stall or mechanically damages the components in the system if the operator forces the system to function.

Causes

A hydraulic lock can affect any system designed to compress gas to operate. Thus, automobiles, marine vehicles, and diesel machines face this problem.

Automobiles

Hydrolock occurs in vehicles when a large amount of water enters the cylinders of the internal combustion engine. This ingress can happen when a vehicle drives through standing water or a heavy rainstorm and the air intake is lower than the water level. The contamination can also occur when the vehicle travels too quickly and creates a large bow wave in a water pool.

Also, the engine coolant can enter the cylinders due to a blown head gasket or excessive fuel, which floods the cylinders. When the fluid fills the combustion chamber, the crankshaft will rotate and force the pistons upwards. This abnormal action creates a reaction force that is stronger than the engine components can handle. This reaction can cause the engine to seize up, which renders it useless.

Also, remember that hydraulic lock in diesel engines is more probable than in gas engines due to a combination of design factors, such as high compression ratio, low combustion chamber volume, and high torque.

The high compression ratio leads to a smaller combustion chamber volume, which reduces the amount of liquid required to cause hydrolock. The higher torque and rotating inertia of a diesel machine also make it more susceptible to catastrophic damage from hydraulic lock.

Marine Vehicles

Hydrolock can occur in marine vehicles such as boats when the water level outside the boat is higher than the exhaust-riser height inside, which allows the water to back-flood through the exhaust and enter any cylinder with its exhaust port open.

Additionally, if you launch the boat off a trailer too quickly or with too much weight aft, it can force water up the exhaust system. Chopping the throttle can also cause the boat's wake to run up the exhaust pipe and into any open cylinders.

Lastly, if you drain the aft ballast tanks or move bags of lead ballast forward, the action can raise the static waterline to a point that is high enough for water to back-flood up the exhaust and cause hydrolock. On turbocharged engines, water can also enter if rust has compromised the intercooler.

Damage

Hydraulic lock can cause a range of damage depending on the speed the engine runs at, the volume of the water, and the size and power of the engine. When water enters the cylinders, the reaction forces can be greater than the engine components can handle. This excessive force can bend or break connecting rods, fracture cranks, heads, and blocks, and damage the crankcase or bearings.

If the engine runs at high speed, it can cause catastrophic engine damage, such as holes in the cylinder head or sump, which will result in an engine replacement. If the engine idles or runs at low power, the engine may simply stop suddenly with no damage. However, you may need to purge the engine, flush out contaminated operating fluids, and replace gaskets.

Severe system damage can occur if you are ignorant of or do not immediately repair your engine after a hydraulic lock. Contact us at Miller Hydraulic Service for hydraulic system and component replacements.

Hose Fittings: A Guide

Fri, 07 Jul 2023 14:40:50 GMT

Hydraulic fittings are found across industries, each with its special application. Whether a professional or a novice learning the ropes, you should identify the right hydraulic fitting that suits your hose size and particular application. Below is a guide on hydraulic hose fittings and their applications.

What are Hydraulic Fittings, and What are They Made of?

Hydraulic fittings connect hydraulic hoses to other components of equipment and machines across industries. You will find hydraulic fittings in water and sewerage systems, hydraulics and assembly lines, construction site hydraulics, and oil refineries.

The market has different hydraulic fittings, each serving a specific purpose. They are made of different materials and come in different sizes with different types of seals and pressure and temperature tolerances. As such, some of these fittings may allow or prevent fluid flow and create a seal, but they serve multiple purposes in some cases.

Hydraulic fittings are made of different materials, including brass, stainless steel, and plastic. Below is a discussion of each of these materials:

Steel . Steel hydraulic fittings are made of steel alloys. Therefore, they are often durable and can withstand relatively higher temperatures compared to those made of materials such as plastic. They are commonly used for industrial applications because of their high-pressure ratings.
Plastic . Plastic hydraulic fittings are beneficial for their corrosion resistance compared to metallic fittings and low cost. However, these fittings are less durable and weak. They are not used in hydraulic applications.
Brass . Brass fittings are not as strong as steel and stainless steel fittings. However, they are highly recommended for applications that need a tight seal. They can withstand moderate temperatures and pressure.
Stainless Steel . This type of fitting is used in high-temperature applications where the environment may be corrosive. These fittings can also withstand high pressure. However, the major setback with stainless steel fittings is that they are expensive.
Aluminum . Aluminum fittings are lighter than steel fittings and resistant to corrosion. While they are less popular, they are applicable for specific applications such as transport hydraulics.

Be sure the fittings you choose are of an appropriate material for your application.

Permanent vs. Field Attachment or Reusable Hydraulic fittings

Hydraulic fittings can either be field attachable or crimped. Field attachable fittings are alternatively known as reusable fittings.

These fittings are less popular than permanent fittings because they are time-consuming and costly. The growing popularity of portable hydraulic crimpers that technicians can carry around means that the use of reusable hydraulic fittings may decline eventually.

On the other hand, crimped fittings are permanent and sealed by a crimper. This type of fitting is more secure compared to field attachable fittings. You can easily identify and assemble them with a crimper, and they are highly reliable.

Types of Fitting Ends and Connectors for Hydraulic Fittings

Below are the most common connector types and fitting ends:

O-ring face seal (ORFS) . This sealing method ensures a reliable and secure elastomeric seal that is used in applications that present a leaking risk. Different ORFS fittings include straight, tee, elbow, and cross ORFS fittings.
Mated angle . These are hydraulic fittings with an angle seat with parallel or straight threads for sealing. When the male and female are threaded together, they form a seal that brings together the mating angle seats.
Tapered thread connectors . This fitting has male and female threads. The threads on the male are on the outside, while the female threads are on the inside. The tapered thread deforms to allow the two fittings to be threaded together, which applies pressure to the couplings and creates a seal. These fittings can contaminate sensitive areas and are subject to threading, so are not used in pneumatic and hydraulic systems.

The Essential Guide to the Most Frequently Maintained Parts of Hydraulic Systems

Wed, 07 Jun 2023 00:20:08 GMT

Hydraulic systems are an essential component in various industries due to their capability to assist in optimal work efficiency and functionality. However, like any other machinery, regular maintenance is required to ensure that hydraulic systems work at their best and remain useful. Failure to perform regular maintenance on hydraulic systems can result in conditions that jeopardize the safety of workers and lead to increased costs, and loss of productivity.

In this blog, we will highlight the main parts of hydraulic systems that need the most frequent maintenance.

Fluids, Filters, and Reservoirs

Maintaining clean fluids, filters, and reservoirs is one of the fundamental ways of ensuring the efficient operation of the hydraulic system. The fluids must be fresh and of high quality, while the reservoir must be inspected regularly to detect contaminations or damages. The filters should also be inspected and replaced when needed. A good rule of thumb is to replace it once a year or every 1,000 hours of operation.

Maintaining clean fluids, filters, and reservoirs will ensure optimum hydraulic system performance and prolong the equipment's lifespan.

Hoses and Fittings

Hydraulic hoses and fittings are critical components of the system, and frequent inspection and maintenance are critical to avoid equipment malfunctions. It is essential to inspect hoses and fittings regularly for any signs of wear, damage, or leaks. Such signs may include frayed edges or cracks in the hoses or altered fittings that do not meet industry standards.

Replacing damaged hoses and fittings or adjusting them to meet industry standards will lead to significant savings in terms of costs and time.

Seals, Gaskets, and O-rings

Seals, gaskets, and O-rings are responsible for preventing leakages within the hydraulic system. These parts need to be inspected regularly to detect any tear, wear, or damage. Failure to maintain these parts can result in leakage, which can cause equipment failure or damage to other components within the hydraulic system.

Regular inspection of these parts is crucial, as they are subjected to high pressure and temperature and can wear out quickly. Replacing such parts regularly will ensure zero or minimal leakage, prolonging hydraulic system performance.

Pumps and Motors

Pumps and motors play a crucial role in the hydraulic system's efficiency and performance. These components need to be maintained regularly to avoid breakdowns, which can significantly interrupt work processes.

It is essential to inspect pumps and motors for any signs of wear, including unusual sounds or vibrations. Maintenance tasks for pumps and motors include aligning couplings, replacing worn bearings, replacing damaged end covers, and checking the fluid levels to identify any contaminants or leaks.

Valves

Proper maintenance of hydraulic valves ensures that the system operates effectively. Valves are responsible for controlling hydraulic fluid flow and pressure, and several issues can arise if they fail. Maintenance tasks for valves include inspection for abrasions, foreign materials, and damages. Loose fittings, rust, or corrosion can also indicate valve problems and such should be addressed immediately during maintenance.

To ensure the hydraulic systems work as expected, it is essential not to underestimate the need for maintenance. Regular maintenance will prevent downtime, save costs, and ensure maximum efficiency for your business. Regular inspection and replacement when needed for the most fragile components of your hydraulic pump will ensure that the hydraulic system remains in top shape, giving operators peace of mind to perform their work activities efficiently and safely.

Unpacking the Trashy Truth: 5 Common Causes of Hydraulic System Failure in Garbage Trucks

Mon, 08 May 2023 20:15:58 GMT

Garbage trucks heavily rely on hydraulic equipment to load and transport waste. Whether you own a single garbage truck or maintain an entire fleet, being aware of common hydraulic system failures will help you prevent downtime and costly repairs. Because hydraulic systems could be exposed to multiple sources of damage, be mindful of these five causes of hydraulic equipment failure.

1. Cavitation

Cavitation is a common problem caused by contamination, especially when the garbage truck is running low on lubricants. Outside elements, such as air and moisture, could contaminate your truck's hydraulic system and result in pump damage.

Cavitation is a by-product of your truck having low levels of hydraulic oil. As a result, insufficient lubrication will cause your pump to draw air from the environment or from dissolved air molecules in your hydraulic fluids. If this happens, you'll end up with tiny gas bubbles in your pumping system, which could damage the pump housing or the surface of your wear plate.

Air bubbles also tend to burst open and cause inconsistent temperatures in your hydraulic equipment. And because garbage trucks heavily rely on the hydraulic system to collect, compress, and offload waste, cavitation could cause significant downtime in your fleet.

2. Inconsistent Pressure

Pressure spikes in the hydraulic system are common in garbage trucks, especially older vehicles. If you often need to replace your hoses or repair damaged cylinders, a pressure relief valve might be the culprit. Vehicles fitted with differential valves are slower when adjusting to pressure spikes. Furthermore, damaged valves may have broken seals, which expose the hydraulic system to fluid leaks, contamination, and inconsistent pressure.

Your garbage truck's hydraulic system will operate more efficiently when fitted with pilot-operated valves. In addition to saving money across your fleet, you'll experience better durability and more precise pressure control in multiple operating environments.

3. Mismatched Components

Mismatched components, such as undersized hoses, are a common source of cavitation and overheating. Not only do undersized hoses restrict airflow, but they also cause unnecessary friction between the pump edges, valves, and filters. An incompatible lubricant could also strain your hydraulic system, especially when lifting or compressing heavy loads.

In addition to pumps and fluids, motors are another common victim of mismatching. An undersized motor will struggle to drive your hydraulic pump, resulting in the slow movement of your garbage container. To avoid mismatching, consult your original equipment manufacturer or an experienced hydraulic service provider.

4. A Worn-Out Hoist Cylinder

Some garbage truck operators may experience a hoist that's stuck in the dump position. Worn hoist cylinders often cause faulty hoist mechanisms. For instance, a misaligned cylinder could disconnect from your hydraulic system and prevent the hoist from lowering.

For the garbage truck's hoist to move freely, it requires an adequately sized and fully functional hoist cylinder, pump, and motor. Garbage particles that are stuck in the hydraulic assembly could also result in a jammed hoist. In most cases, you'll need to replace the affected components to prevent the problem from recurring.

5. Lack of Preventative Maintenance

Poor maintenance will almost certainly result in hydraulic system failure. To avoid downtime, you should recognize the value of preventative maintenance. The preventative approach encourages people to proactively maintain their machines, vehicles, and other equipment. Rather than wait for your garbage truck's hydraulic system to break down, implement a maintenance schedule where you regularly inspect pumps, hoses, valves, and cylinders.

Garbage trucks operate under harsh environmental conditions and may be exposed to fluids leaks, pump damage, and even worn-out wiring inside the motor. Timely inspections could help you predict and prevent hydraulic issues before they cripple your truck's performance.

To keep your hydraulic systems in good condition, you need an expert hydraulic repair service by your side. Miller Hydraulic Service specializes in both commercial and industrial hydraulic repair. Since 1991, we've worked closely with our clients to carry out repairs and rebuilds on a wide variety of hydraulic equipment. Are you in need of hydraulic system repair for your garbage truck?

Hydraulic Breakers: What Are They?

Tue, 28 Mar 2023 05:06:47 GMT

Various types of heavy machinery are essential for construction projects. One of the tools that are becoming popular in the construction industry is a hydraulic breaker or hammer. Excavator hydraulic breakers are available in many types and use pressurized oil. Here is what you need to know about hydraulic breakers.

Define Hydraulic Hammer or Breaker

A hydraulic hammer, also known as a hydraulic breaker, is a construction machine that demolishes structures and breaks large materials into small pieces. The machine uses hydraulic principles by applying high pressure on a small canister that has pressurized hydraulic oil in it. The hydraulic hammer are composed of an outer valve or inner valve as well as a cylinder.

Hydraulic hammers use pistons to convert kinetic energy to hammering energy. The piston contains a front head that provides support to the machine and a back head with nitrogen gas. Most hydraulic breakers come in the form of attachments to mobile equipment such as diggers.

Discover the Benefits of a Hydraulic Breaker

Here are some of the many reasons you should try a hydraulic breaker for your next excavator project:

Protects Other Equipment

A hydraulic breaker can protect other parts of the excavator from damage. For instance, your excavator can stumble upon a hard surface in the ground. If the excavator is using a bucket, the bucket's teeth will likely become damaged. The solution is to replace the bucket with a hydraulic breaker attachment so that you can break the hard material without damaging the excavator.

Highly Efficient

If you were to use a hammer to break a hard surface, you would take several days or weeks to complete the job. An excavator with a hydraulic breaker can do the job in minutes or hours. You also have an easier time handling the mess the excavator leaves behind. High efficiency means that your projects are executed smoothly and without any delays.

Budget Savings

One way to reduce the time taken to break a hard surface using a hammer is to hire more manpower. But more workforce means more salary and increased strain on your budget. One hydraulic breaker can do the same job within a short time. The result will be massive savings of both money and time.

Low Fuel Consumption

Contrary to myth, hydraulic breakers don't use a lot of fuel. In fact, some hydraulic breakers can consume less fuel than other machines that do the same job. While the initial price of hydraulic breakers can be high, you will save much more money on fuel in the long term.

Customization

The manufacturer of your hydraulic hammer can customize it to fit your specific needs. You will get a hydraulic breaker that has the appropriate backhoe and skid steer. As a result, you don't have to worry about any errors that may occur due to the use of equipment with the wrong specification.

However, you can only get these benefits if you purchase the hydraulic breaker instead of renting one. When you rent a hydraulic breaker, you will only receive a unit that the renter has available instead of the one you want.

Learn the Types of Hydraulic Breakers

There are many hydraulic breakers, including side-mounted hydraulic breakers, top-mounted hydraulic breakers, and silenced-hydraulic breakers. Side-mounted hydraulic breakers have two thick steel springs on either side of the breaker. That makes the breaker ideal for demolition and construction jobs. Also, you can quickly dismantle the side-mounted hydraulic breaker for easier maintenance.

The splints on the top-mounted hydraulic breaker are mounted on the top. The design is prone to vibrations and noise but can deliver more downforce. On the other hand, the silenced hydraulic breaker has greater vibration and noise levels since the breaker has a fully closed box design. The silenced hydraulic breaker also has more versatility.

If you plan to use a hydraulic breaker, the team at Miller Hydraulics Service, Inc., can help you. We provide various hydraulic services such as construction hydraulics, excavator hydraulics, and hydraulic machinery for farming. Contact us today for more information.

6 Common Causes of Hydraulic Seal Failure

Thu, 01 Dec 2022 18:54:32 GMT

Hydraulic pumps and cylinders need seals to prevent leakages and protect components like rods. Sadly, seals often fail and lead to major problems when they do. The most common failures include aggravated fluid leakages, systematic contamination, and blowouts.

That said, numerous issues can cause hydraulic seal failure. Read on to familiarize yourself with the most common causes of seal failure and put yourself in a better position to prevent them in the future.

1. Hardening

Most hydraulic cylinders function well when in contact with hydraulic fluids that don't exceed 180° F in temperature. A higher range can negatively impact numerous components in these machines, including the seals.

When you expose hydraulic seals to extreme temperatures, they harden. That is a significant issue because it leads to lost elasticity. Hardened hydraulic seals often crack, which can easily lead to component failure.

2. Chemical Attacks

Various chemicals damage hydraulic seals. For instance, new fluid additives like amine preservatives can attack the backbone of the rubber polymer and make the material more brittle, which encourages premature failure.

A seal's material is also highly likely to break down if it encounters acid or other corrosive materials. That is why experts recommend you seek professional help before you pick hydraulic seals. Otherwise, if you get an incompatible product, the products you use may lead to chemical attacks and destroy your seals.

3. Contamination

Suppose you use your cylinder in an environment full of elements like dust, abrasive grit, mud, and weld splatter. In that case, these items can get into your device and lead to contamination.

Unfortunately, when external contaminants gain access to a hydraulic cylinder or attach themselves to its rod, they can lead to dirty seals. And as these components get filthier, they become less reliable and lose their ability to keep out debris, including dirt particles.

If you let this vicious cycle persist, the seals will eventually fail and compromise the entire cylinder's condition and functionality.

4. Fractures

Numerous issues can encourage your hydraulic seals to fracture. These include excessive backpressure, extreme temperatures, and pressure shocks. Also, the problem is common in components made of low-grade materials.

Fractures are bad because they often turn into long cracks and encourage a seal's dynamic side to break off. Plus, you are likely to notice signs of burnt seal surfaces when fractures are present.

5. Swelling

Hydraulic seals are compatible with specific fluids. For instance, nitrile butadiene rubber (NBR) components work seamlessly with petroleum-based hydrocarbons like diesel and mineral oils. On the other hand, they are incompatible with strong acids and highly aromatic hydrocarbons.

You shouldn't use your seals with incompatible fluids because their encounter can cause the former to swell. A swollen hydraulic seal loses its shape and becomes loose over time. Eventually, they cause significant issues like leaks.

6. Poor Installation

Hydraulic installation may seem easy, but it's not. Although most of these components are made of rubber, which makes them malleable and durable, they are still susceptible to damage.

That said, professionals use various tools to install hydraulic seals. These include piston seal compressors and adhesives. They also apply different tried-and-true tricks. For instance, an expert can heat a seal before installation to improve its elasticity.

Without the necessary skills and tools, you will likely install hydraulic seals improperly. For example, you may use the wrong equipment, cut or dent the seal's lip, and reduce its efficiency.

If your hydraulic cylinders operate erratically or have lost their effectiveness, the problem may be faulty hydraulic seals. To be sure, let Miller Hydraulic services help you troubleshoot.

The good news is that hydraulic hose technology has come a long way over the years. As a result, you now have access to advanced tools and resources that can help prevent hydraulic hose leaks.

Discover four useful techniques for addressing leaking hose issues and preventing equipment downtime.

1. Monitor the Electrical Conductivity of Your Hose

In the past, hydraulic hoses were primarily for safety, durability, and cost-effectiveness. Technical advancements in hydraulics have now opened the door for unique and dynamic hose designs. With a stronger link between hose functionality and fluid dynamics, you can install hoses specifically for transporting the fluid systems in your equipment.

For example, some hydraulic hoses need electrical conductivity to drain static electricity and optimize fluid movement. Other hydraulic systems need to be poor conductors to limit the flow of current and prevent electrocution. You now have the option to install sensors on your equipment to monitor electric conductivity in real time. If the electric current is too high, you can drain the excess through grounding, thus ensuring equipment safety.

2. Practice Preventative Maintenance

Preventative maintenance has become the gold standard for maintaining industrial equipment. Rather than waiting for your machines to break down and cause downtime, preventative maintenance involves proactive detection and fixing issues before they become worse.

So how can you implement such a strategy for your hydraulic hoses? Begin by tracking the key performance indicators (KPIs) for your equipment. KPIs may consist of mechanical loads, fluid transportation times, or hose temperature. When you notice that your hoses have reduced performance, consider scheduling on-site maintenance .

A reputable hydraulic repair service can inspect your tubes, fittings, pumps, and valves for any potential issues. And by addressing the problem early, you'll avoid equipment downtime and bottlenecks in productivity.

3. Install Hoses Compatible With Your Equipment

Hydraulic hose compatibility is a significant predictor of safety and performance. However, standardized guidelines for hydraulic hoses only provide general information for hose dimensions and performance. If you want to get the best out of your equipment, consider additional compatibility factors.

Start by checking the entire design of your hydraulic hose, including the inner, middle, and outer layers. All three layers should be compatible with the transported fluid and the movement of your equipment.

In addition, flexible machines such as cranes need robust hoses that withstand high pressure and abrasive conditions. If you're in the oil or agricultural sector, consider double-wire hoses braided from steel for more durability. Matching your hose type to your equipment environment optimizes productivity and reduces maintenance costs.

4. Install the Correct Hose Length

Selecting a hose of the correct length is not necessarily a new technique. Yet, modern hydraulic systems need complex hose assemblies that ensure optimal temperature, pressure, and electrical conductivity. Installing hoses of incorrect length may not only result in leaks, but you may also compromise workplace safety.

You have several ways to detect a lengthy hydraulic hose. For example, excessive vibration from metal components may indicate a long pipe that's causing unnecessary friction. On the other hand, a short hydraulic hose may result in loose hydraulic fittings, valves, and pumps.

Flexible and elastic hydraulic hoses are a useful solution for length issues. Elastic hoses that are compatible with your equipment will reduce excessive resonance and fluid leaks. Furthermore, your team will enjoy the noise reduction from smooth and efficient machines.

Factors to Consider When Choosing a Hydraulic Pump

Mon, 21 Nov 2022 15:07:30 GMT

Several factors determine the efficiency and lifespan of a pump. Knowing what to look out for when selecting a pump will ensure you pick one that will serve you for long. When you go to a vendor, you should already have an idea of what you need in a pump. We put together this list of important factors to consider when choosing a hydraulic pump to help you make the right choice.

Pressure

A hydraulic pump's pressure rating determines how much pressure a pump can withstand without developing an internal leak or damaging its internal components. Some of the factors that contribute to the pressure rating of a pump include its length and fittings, internal components like valves and filters, and static lifts.

Pumps are pressure rated under the same temperature, inlet pressure, and speeds, determining their capacity rating. A vane pump is suitable for 150 to 250 psi pressures, while pressure piston pumps are suitable for pressures above 500 psi.

Fluid Type

Consider whether the material of the pump is compatible with the types of fluid the pump shall come into contact with. A pump's compatibility with different fluids will also partly depend on the properties of the fluid. Some liquid properties you should consider before selecting a pump include:

• The liquids' viscosity

• Whether or not the liquids are abrasive

• The liquids' temperature

• The solids present in the liquids and their concentration

• The liquids' vapor pressure

• Whether the liquids are shear sensitive

Pump Placement

Where you plan to place the pump will determine which type of pump is most suitable. If you will place the pump outside your premises, it must have features that protect it from freezing temperatures. If the pump placement is in a hazardous environment or one with dust or explosive vapors, the pump you select must have a motor that can withstand the mentioned elements.

Capacity

A pump's capacity, flow rate, or volumetric output is one of the most essential features determining its performance. A pump's capacity shows the volume of liquid that can flow through the pump at a given time. The normal and rated capacities are the capacities your pump will likely operate on most of the time. The normal capacity is lower than the rated capacity, which is the flow rate guaranteed by the manufacturer

A pump with a lower capacity will take more time to pump liquid from an area than a pump with a higher capacity rating. However, higher capacity rated pumps cost more than lower capacity rated pumps. Therefore, you must consider your budget when choosing a pump based on its capacity rating.

Drive Speed

The average drive speed for most pumps ranges at 1200 or 1800 rpm. However, mobile hydraulic pumps may have a drive speed of 2000 rpm if driven by internal combustion engines. On the other hand, industrial hydraulic pumps may have speeds of 4000 rpm.

The maximum speed that a pump can withstand depends on its pressure rating and ability to avoid cavitations. If your pump will operate at high pressures, you must also inquire about its minimum speed to ensure it does not overheat when it is running.

Before selecting a pump, you must also consider constant and intermittent drive speed ratings. A pump's constant speed rating will tell you the maximum speed and pressure it can withstand while constantly operating, while the intermittent speed rating will tell you the maximum speed and pressure it can withstand when operating for short times.

Efficiency

Some of the efficiency parameters you must consider when selecting a pump include overall mechanical and volumetric efficiency. A pump's efficiency will determine how much work it can take.

Consulting an experienced hydraulic pump contractor on the above factors will ensure you select a pump you can trust to serve you well. Contact us today for more information on different hydraulic pump selections.

Tips for the Safe Use of Hydraulic Systems

Mon, 21 Nov 2022 15:07:30 GMT

Hydraulic systems are essential in making work efficient. The generated force at the effector end of the system is enough to handle different complex tasks. Still, harnessing this potential requires you to be cautious to ensure that you and your workers are safe.

All hydraulic systems require a certain level of respect, given the gravity of potential injuries that result from mistakes. This piece describes a few safety precautions that you can take to ensure your hydraulic system is safe.

Employee Training

Mistakes can occur when someone does not bleed pressure on your system or leaves unsecured loads. Workers can get lax when they use hydraulic equipment for a long time. In addition, hasty repairs, especially on a strict deadline, may lead to accidents. The best way to ensure your workers follow safety practices is to bring in a hydraulic system expert.

Experienced hydraulic technicians follow the proper procedures OSHA recommends regarding modification, hot environments, and periodic inspection. Inviting such experts to your organization ensures your workers comply with the various safety protocols.

Your workers also require training about personal protective equipment. For example, employees must wear protective gloves and safety glasses when inspecting potential leaks. Moreover, they should examine the system periodically to identify hazardous defects such as leaking pumps and bent components.

Proper Installation

Proper installation will prevent accidents as you use the hydraulic system. For instance, the hoses and the rest of the hydraulic assembly have a shelf life. Therefore, these items may be unsafe without proper storage, service, or installation. The pressurized liquid constantly exerts pressure on the system's weakest points, which could be dangerous.

Hire an expert to select and install all your hydraulic system components. The professional can detect defects in the equipment and ensure the parts do not break or burst. The expert also recommends a suitable area to install noisy components to avoid noise pollution. Such safety precautions ensure that your business takes care of its workers and the environment.

Preventive Maintenance

The concept of preventive maintenance in engineering applies to different machines in your workshop. This equipment maintenance principle ensures that the system is safe to operate. For example, preventing contaminants from entering the hydraulic system can help avoid damage and accidents as you use the system.

A hydraulics expert helps you create a maintenance schedule based on the manufacturer's specifications. The technician also prioritizes the equipment that needs maintenance based on whether the equipment is mobile or stationary. Other factors to consider when making a preventive maintenance schedule include storage condition, external influences, working pressure, frequency of use, and the integrated components.

Standards Adherence

Different standards govern the installation and use of hydraulic systems. If you purchase the system for the first time, you may not be familiar with these standards. However, getting an expert in hydraulics can help promote safety at your workplace by adhering to these laws. Such measures are also essential in helping your company avoid legal problems due to non-compliance.

For example, the hydraulics expert can follow the ISO 12100 standard. This standard dictates the basic design principles, methods of risk assessment, and reduction of hazards. Using such a standard when designing, using, and maintaining hydraulic systems can significantly reduce risks.

Hydraulic Cylinder Drift: Triggers and Solutions

Mon, 21 Nov 2022 15:07:22 GMT

If you run a hydraulic system of any kind, you need to be aware of the risk of hydraulic cylinder drift. This problem can occur for several reasons and can have a significant impact on your business.

Read on to understand what hydraulic cylinder drift is, why this issue happens, and how you can avoid its effects on your system.

What Is Hydraulic Cylinder Drift?

Hydraulic cylinders are an important part of many industrial and construction applications. These devices use hydraulic fluid to create a force that can move objects or apply pressure. You can find hydraulic cylinders in a wide range of industrial machines, including:

Excavators
Backhoes
Forklifts
Cranes

Hydraulic cylinder drift occurs when the fluid in the system leaks out of the seals around the piston, which causes the piston to move slowly back and forth inside the cylinder. This movement is often referred to as drift.

Because hydraulic drift happens when the piston in a cylinder moves without authorization by the system, the issue can cause many problems, including:

Delays in production
Unexpected downtime
Reduced operational efficiency
Product damage

In some cases, hydraulic cylinder drift can even be dangerous. If the piston moves while someone works on the machinery, they might suffer serious bodily injuries.

Why Does Hydraulic Cylinder Drift Happen?

Hydraulic cylinder drift can happen due to several reasons, but the issue often comes down to two main factors.

Poor System Design

Without a proper design, your system can put too much stress on the seals around the piston. The seals will likely break down with time, which allows fluid to leak past them. As a result, the piston can move unexpectedly and eventually cause drift.

The wrong size piston for the cylinder can also cause cylinder drift. If the piston diameter is too big, the piston will experience a larger drifting force that can add to the drift effects. In general, the larger the piston, the greater the surface area exposed to fluid pressure. This increased exposure creates more force on the piston, which makes the component drift more.

Poor Maintenance

Even with the right design, a hydraulic system will eventually experience wear and tear after years of use. Without proper maintenance, this deterioration can cause the seals to break down and allow hydraulic fluid to leak out. Dirt and other contaminants can also build up in the system and cause the seals to break down.

When the seals break down, the air then enters the system. This air can cause the piston to move back and forth inside the cylinder, which eventually leads to cylinder drift.

In addition, faulty pressure relief valves could catch you by surprise if you're not keen on maintenance. If these valves fail, they cause the seals to slowly deteriorate and allow fluid to leak. A cylinder drift issue then follows afterward.

How to Identify Hydraulic Cylinder Drift

A few signs can tell you when you have a drift problem in your system. Call an expert if you notice:

Unexplained fluid leaks
Slow or sluggish movement of the machinery
Reduced effectiveness, especially with heavy load lifts

Usually, these problems occur gradually over time. You need to catch them early to prevent further damage to your system.

How to Prevent Hydraulic Cylinder Drift

To prevent cylinder drift, routinely check for system leaks and make sure you repair them promptly. In addition, if you intend to shut down for an extended period, remember to support the equipment with blocks or jacks to prevent any movement.

Anytime you shut down your hydraulic system, there's a possibility for cylinder drift. This issue occurs when the system pressure bleeds down, which allows the weight of the equipment to push down on the piston. As a result, the cylinder drifts downward. Over time, this issue can cause significant wear and tear on the equipment.

Follow these simple steps to prevent hydraulic cylinder drift and extend the life of your equipment. However, if you need help with your hydraulic system, contact Miller Hydraulics Service today.

3 Common Reasons for a Short Hydraulic Pump Life

Mon, 21 Nov 2022 15:07:20 GMT

Proper machinery and vehicle maintenance ensure your mechanical assets prolong their lives and serve your company until they are irreparable. Therefore, technicians and mechanics involved in the installation and maintenance of mechanical components should understand their functions and placement. Such knowledge applies to hydraulic pumps, a critical part of any machine.

A hydraulic pump is a machine that converts mechanical energy into hydraulic energy. Hydraulic pumps use an electric motor or gasoline engine to drive pistons inside a cylinder. The piston creates pressure that forces fluid from the pump's reservoir into the cylinder. The fluid then flows through valves and hoses to the pump's outlet, where it can be used to power hydraulic tools and machinery.

While some manufacturers and technicians can offer guarantees on the lifespan of their hydraulic pumps, adverse environmental conditions, human errors, and wrongful treatment can shorten a hydraulic pump’s life. Here are three common reasons for a short hydraulic pump life.

1. Contamination

Hydraulic pumps contain sealant materials that ensure they remain air- and water-tight, with varying degrees of tolerance for different machines. For example, machines that operate in high-moisture conditions should possess better sealant qualities than machines designed for general and moderate conditions.

However, contamination could occur from outside elements when the pump becomes compromised. Air and water molecules might mix with the pump fluid destroy interior sections.

Air contamination results from air molecules that enter the pump via cracks or when fluid content is low. This contamination allows the gaseous elements to mix with the fluid.

Water contamination occurs inside a hydraulic pump when water molecules enter the pump and mix with the hydraulic fluid. This infiltration can happen if friction and unnatural wear and tear compromise the pump's seal, the hydraulic fluid is impure, or the pump operates in an environment with high water vapor.

When the pump operates with these contaminants, it can decrease efficiency. Moreover, it forces the pump to operate at higher frequencies or use more energy.

2. Incorrect Installation or Repair

Human errors can occur when an individual installs, repairs, or reinserts a hydraulic pump. The main components of a hydraulic pump are the electric motor or gasoline engine, the piston, the cylinder, the valves, and the hoses. These parts work together to convert mechanical energy into fluid power. Therefore, when these parts become compromised, they shorten the hydraulic pump's lifespan.

Improper installation can cause the pump to misalign with the drive shaft. It will put undue stress on the pump and eventually cause it to fail. Incorrect seals will leave gaps that allow contaminants to seep into the hydraulic fluid and damage the pump. Additionally, incompatible parts might stress the pump as it may cause vibrations, which release the pump from its secure position and degrade it faster.

3. Extreme Temperature Changes

Pumps subjected to extreme temperatures or operated in extreme weather conditions without any upgrades or maintenance will fail faster than their counterparts. High temperatures can break sealants or thin the hydraulic fluid, which causes it to evaporate through gaps and cracks. Additionally, low temperatures may freeze and contract metallic components and thicken the pump fluid, which increases the strain and causes the pump to overwork beyond its operational limits.

You should hire qualified technicians as they can ensure your hydraulic pump settles in its proper position to avoid any future mishaps. Additionally, professionals will assess your hydraulic pump needs and procure the correct parts that fit snugly with your machine components. Proper maintenance, installation, and repair will ensure the longevity of your hydraulic pump.

Here's Why Hydraulic Hoses Fail

Mon, 21 Nov 2022 15:07:19 GMT

Hydraulic hoses remain an often-overlooked component of hydraulic maintenance. This is despite the fact that they are vital to the effective and safe running of any hydraulic equipment. The hydraulic hoses act as the equipment's blood vessels. They use hydraulic fluid to convey pressure to the equipment's many components.

Hydraulic hoses can be dangerous if not maintained. Damaged hydraulic hoses are the main source of unintentional injection. Such mishaps can result in personal injuries to workers. Thus, it's essential to know the reasons for the failure of hydraulic hoses.

In light of this, let's examine some major reasons why hydraulic hoses fail.

Hydraulic Hose Erosion

Hose erosion is the phenomenon of material loss from a surface as a result of mechanical contact. Concentrated, high-velocity streams, especially from contaminant-containing fluid, cause tube erosion. The stream starts to destroy the hose's inner tube. This may lead to the hose weaknesses and breakdown.

Narrow Hose Radius

Hydraulic hoses have an allowable bend radius to help deter kinks. Kinks restrict the passage of fluid and lead to many problems.

A tight hose kink stretches the hose components on one side and compresses them on the other. This generates tremendous strain inside the hose structure. This might lead to a reduction of the hydraulic hose's performance capabilities. Because of the increase in pressure, kinks may also trigger the hose to explode.

Heat Hardening

Extreme temperature is a risk that hydraulic hoses face. Extreme temperatures can originate from heat conveyed by the hydraulic fluid. Additionally, they could result from the surroundings around the hose.

Every hydraulic hose has a temperature rating, which specifies the highest heat it can take before it develops issues. The hose will overheat, lose its elasticity, and even become brittle, stiff, and rigid. Additionally, the inner tube will begin to crack and even contaminate the system. Contamination of the system may lead to hose failure.

Pressure Surges

All hydraulic hoses have a distinct pressure standard built into them. Thus, based on your requirements, you need to choose the appropriate hose for that use. Any pressure above the intended range is always hazardous to the hose since it damages the hose and shortens its lifespan.

Incompatible Hydraulic Fluid

You need to remember that not every type of fluid is compatible with every hydraulic hose. A hydraulic hose may disintegrate if you use an inappropriate fluid. This can culminate in hydraulic hose fluid spillage as well as injuries.

Contamination

Materials and other debris might accumulate in the hydraulic hose if they are not removed. As a result, the hose may get clogged. Hydraulic fluid contamination can make the system fail to operate and result in hose deterioration.

Site Damage

Site damage occurs when the hydraulic hoses get affected by items in the vicinity of where they operate. Site damage can result from falling debris, concrete, earth, and rocks. This type of damage is prevalent when the hose pipe remains unprotected.

Faulty Fixtures

You need special fittings to secure hydraulic hoses. These fittings come in a range of sizes and threads to accommodate various hose ports. Leaks can occur when a hydraulic hose gets installed with an inappropriate fitting. Over time, this can compromise the hydraulic hose's assembly.

If you feel that your hydraulic hoses have issues, contact a hydraulic hose repair professional right away. When you overlook the issues, they can give rise to other problems, which may cause even more damage. Thus, heed the warning signs and have your hoses repaired or replaced before they fail or break down.

Applications of Hydraulics in Everyday Life

Mon, 21 Nov 2022 15:07:17 GMT

Hydraulics is the application of liquid pressure to mechanical functions. Hydraulics is an age-old technology that has become an integral part of our daily lives. With hydraulics, people have invented various practical, productive, and safer devices that enhance life.

The following are some ways hydraulic systems contribute to our daily lives.

Earth-Movers and Excavators

If you work in the excavating business or any type of commercial construction, you will need to have the right hydraulic applications to get the job done. Dozers, backhoes, and the like use hydraulic systems to efficiently dig and move the earth so that construction can take place safely.

Additionally, hydraulic seals are often used to maintain the newly moved dirt is correctly sealed before placing the finishing touches on the construction project. Without the proper hydraulic systems, construction can be slowed and even simple tasks can become strenuous.

Textile Manufacturers

Mechanical, Teflon, and shaft seals all require high-pressure hydraulics to be created effectively. To manage the compact spinning, high pressures, and frequent rotation of air rams, hydraulic seals are used to maintain safety and efficiency. Without the right hydraulics, compact spinning can grow unruly and create a hazardous environment.

But with hydraulic seals and equipment, production can go on as normal so that textiles can be created without any hiccups or inconsistencies. Equipping your business with the right hydraulics can make a difference in the speed and consistency that your textiles are produced.

Automotive Industry

Hydraulic systems are abundant in car repair facilities. A hydraulic system operates by lifting the car off the ground so that the work underneath can be conducted easily.

Various power and hand tools in the automotive repair industry also incorporate hydraulics. Among the most visible hydraulics applications in auto repair are the aforementioned two- and four-post lifts that raise cars during servicing and inspections. Your car's portable jack is also an example of a hydraulic system in the auto industry.

Waste Management

Players in the waste management industry have widely adopted hydraulics. Dustcarts, waste compactors, street sweepers, and crushers all use hydraulics for the following advantages to the businesses:

Minimized cost
Reduced noise levels
Better fuel use
Extended lifespan

Garbage trucks, crushers, and compactors utilize hydraulic force and can compress large amounts of waste. As a result, the trash takes up less space and may stop landfills from filling up so quickly.

Second, hydraulic systems make lifting and loading solid and liquid waste far easier for garbage trucks. Additionally, dumpsites and landfills may use hydraulic systems to lift and dump the garbage.

The street sweeper is another hydraulic system. A hydraulic motor rotates the brushes of street sweepers. The use of hydraulics is also prevalent in creating high-pressure mists of water to wash the streets. As a result, the cleaning staff uses less water while also allowing a high degree of hygiene.

Elevators

Americans ride elevators approximately 103 billion times per year. One type of elevator uses hydraulics. Hydraulic elevators use hydraulic fluid and pressure to manipulate the elevator cab.

An electric pump moves hydraulic fluid into a cylinder. As the fluid builds up, it pushes the piston inside, which causes the elevator to lift the cab to the corresponding floor. During the descent, an electrical valve releases the hydraulic fluid gently for a smooth motion.

Hydraulic lifts have fewer moving parts than traction elevators, hence lower repair costs. They are ideal for buildings with under 60 feet of travel.

If you look around your home or workplace, you may undoubtedly find hydraulics in use somewhere. Although hydraulic systems are immensely versatile, they are relatively straightforward in their operation.

Mistakes That Could Harm Your Hydraulic System

Mon, 25 Jul 2022 18:45:58 GMT

Hydraulic system operation and maintenance is no easy feat. The system features numerous moving parts that you must monitor closely to avoid potential issues. Even the slightest mistake can cause significant problems down the road, so you need to be as vigilant as possible. Discover some of the most common hydraulic mistakes below and learn how to avoid them.

Using the Wrong Fluid

The function of hydraulic fluid is to transfer energy throughout the system. Moreover, the fluid lubricates the system's components and prevents the parts from oxidation. As such, you must use the hydraulic fluid specified in your system's manual. If you use the wrong hydraulic fluid, it can reduce the efficiency of your system and cause long-term damage to its components.

The critical feature to consider in your fluid selection is viscosity, a measure of a fluid's resistance to flow. For instance, if the fluid you choose has a lower viscosity than recommended, the fluid cannot lubricate the system adequately.

In the same way, if the fluid you select has a higher viscosity, it will not flow through the system properly. In either case, using the wrong hydraulic fluid can cause severe problems down the road, so consult your system's manual before you settle on the best.

Not Changing the Hydraulic Fluid Regularly

Just like motor oil in a car, hydraulic fluid breaks down over time and needs replacement. The frequency with which you need to change the hydraulic fluid will depend on the specific system and how frequently you use the system.

Not changing the hydraulic fluid as recommended can lead to serious problems, such as decreased efficiency, increased wear on system components, and even system failure.

However, you should note that hydraulic oil is costly. So, you don't want to change the oil more often than necessary. To strike the right balance, consult your system's manual for specific guidance on hydraulic fluid changes.

Not Checking the Temperature

The hydraulic fluid in your system may reach high temperatures during operation, which can cause long-term damage to the system if not properly monitored.

To avoid this problem, check the hydraulic fluid's temperature regularly and take steps to keep it within the specified range. For instance, you may need to install a cooling system or make adjustments to the way you operate the system. Consult your system's manual for specific guidance on temperature maintenance.

Installing the Filters Incorrectly

Hydraulic filters play an essential role in keeping the hydraulic fluid clean. Unfortunately, the hydraulic fluid circulates through the system and picks up debris, which can clog the system's components and reduce efficiency. To avoid this problem, you must install the hydraulic filters correctly and change them as needed.

However, installing the hydraulic filters incorrectly is a common mistake. In some cases, people fail to install the filter at all. In other cases, they may install the filter upside down or backward. If you lack the skills and experience for proper installation, consult your system's manual for specific guidance on the task.

Besides proper filter installation, you should change the hydraulic filters regularly. Again, the frequency you need to change the filters will depend on the specific system and how often you use the system. Not changing the hydraulic filters as recommended can lead to severe problems, such as decreased efficiency, increased wear on system components, and even system failure.

The hydraulic system is a vital component of many machines and vehicles. But the system demands proper care and usage to boost hydraulic efficiency and longevity.

5 Common Defects That Undermine Hydraulic Cylinder Performance

Tue, 28 Jun 2022 20:54:28 GMT

Hydraulic cylinders influence the hydraulic systems' overall performance. Using a defective cylinder lowers your operating efficiency, increasing downtime and production expenses. Moreover, delaying repairs exacerbates the condition, resulting in unnecessary rebuild or replacement costs. This blog outlines common hydraulic cylinder defects.

1. Cylinder Misalignment

Using a misaligned cylinder undermines your hydraulic system's loading capacity. For example, misalignment often causes side loading, inhibiting efficient cylinder retraction. You may not notice the misalignment unless you monitor your system's output over time.

A common cause of misalignment is using the wrong cylinder mount. A cylinder mount's primary function is to maintain the right cylinder position. Factors like load capacity and stroke size influence the best-fit cylinder mount. For example, long strokes increase the risk of misalignment, necessitating mounts that are more resilient.

2. Bent Rod

Using the wrong rod diameter may also undermine your hydraulic cylinder's efficiency. A cylinder rod is integral to delivering the right force or power for specific tasks. A weak cylinder rod increases its chances of bending under large loads. A bent rod causes power loss, reducing your hydraulic system's energy efficiency.

Cylinder rods should also comprise the right material. Remember, materials offer different mechanical and chemical properties. For example, some materials offer superior tensile strength, meaning they can hold larger loads.

Additionally, cylinder rods should use materials that can withstand the hydraulic system's operating temperature. Usually, manufacturers account for such factors when designing and building cylinder rods. However, you may have installed the wrong cylinder rods, predisposing your hydraulic system to failure.

3. Cylinder Ballooning

Hydraulic systems leverage their design and build for optimal efficiency. For example, the cylinder diameter should match the seals, ensuring little to no energy loss. However, your hydraulic cylinder may balloon, altering the system's efficiency.

First, ballooning creates gaps between the cylinder walls and seals, allowing high-pressure fluids to escape. You may notice that your hydraulic system no longer has its initial power or cannot support the same load. Moreover, the fluid leak may cause localized heating and wear out the seal over time until your hydraulic system fails.

4. Cylinder Corrosion

Water is possibly the biggest inhibitor of hydraulic system efficiency. It corrodes hydraulic cylinders and rods, compromising their surfaces. For example, water leaks may cause the cylinder barrels to rust, increasing friction with the seals.

In extreme situations, corrosion may cause pitting, altering the cylinder's surface integrity. Pitting poses significant operating challenges, especially when you cannot reverse it through a simple repolish. You might have to suspend operations for a while to allow adequate servicing to restore its smooth surface.

Corrosion also contaminates your hydraulic system's fluids. Contamination often alters the fluid's properties, reducing its efficiency. Thus, you might need to clean or replace the hydraulic fluid depending on the extent of the contamination.

Cylinder corrosion should be a top concern for people using or storing hydraulic systems outside. Outside storage exposes your hydraulic cylinder to weather elements that wear out its components, predisposing it to leaks. Thus, an easy remedy would be to cover your hydraulic cylinders when not in use, or build a shed to protect them from direct sun and rain exposure.

5. Defective Bearings

Bearings transfer motion between moving components, ensuring proper cylinder clearance. Occurrences like mechanical shock and overloads may damage the bearings, impacting your hydraulic cylinder's efficiency.

Remember, bearings maintain smooth cylinder clearance. Mechanical shocks often damage the bearings' components and alter their movement. For example, the shock may destroy eye bearings, resulting in skewing.

Always monitor your hydraulic cylinder to timely detect arising defects. Otherwise, waiting until your hydraulic system breakdowns may cost you significant repair expenses. Consider scheduling an inspection or maintenance with Miller Hydraulics Service, Inc. Our technicians offer onsite services and will restore your hydraulic cylinders to their optimal performance.

Why You Need to Choose the Right Type of Hydraulic Fluids for Your Hydraulic Equipment

Wed, 16 Mar 2022 17:01:20 GMT

Hydraulic fluids are a critical part of any hydraulic system. Not only do they lubricate moving parts to prevent friction, but they also act as temperature regulators within your equipment. Therefore, choosing the right type of hydraulic fluid will determine the overall performance of your hydraulic equipment.

Whether you're servicing hydraulic hoses, cylinders, or pumps, take the time to understand which fluids are best suited for your equipment. Read on to learn why you should choose the right types of fluids and how an experienced hydraulic service can help.

Hydraulic fluids are different from the multi weight car oils that are most known. Hydraulic oil has a poor viscosity INDEX (the oils ability to maintain its thickness over a wide temperature range) Such as cold weather demands thinner fluid, or additives.

AW in hydraulic oil is ANTI WEAR additives.

· 32 = 10 Weight

· 46 = 15 Weight

· 68 = 20 Weight

Ensuring Proper Lubrication

A critical function of hydraulic fluids is to provide lubrication between moving parts. Hydraulic fluids are unique cocktails of chemical materials designed to enhance performance. For example, synthetic fluids consist of special additives that reduce friction in your machines. Such fluids also absorb heat, providing a release mechanism for your hydraulic equipment during peak hours.

When working with hydraulic fluids, proper application is essential. Consider fluids that remain in place to provide continuous protection against friction. For machines that operate in rainy conditions, you should consider synthetic, low-viscosity fluids that have water-resistant properties. These features will prevent your fluid from washing away and exposing moving parts.

Providing Temperature Control

If you frequently experience overheating in your hydraulic equipment, you may need to choose a better type of fluid. Hydraulic fluids regulate the temperature within your machines by absorbing and dissipating heat. Therefore, your lubricant should maintain a stable chemical composition even at high temperatures.

When users select fluids with low heat dissipation, overheating can occur. If your fluid of choice cannot release heat quicker than it absorbs it, you may end up with an overheated machine. You can select the right type of hydraulic fluid by considering its chemical composition and your machine's capacity.

Keeping the Machine Clean via Filtration

Hydraulic fluids are useful for more than just lubrication and temperature control. These fluids also act as a filtering mechanism, removing sludge, debris, and other particles that could contaminate your hydraulic system. Debris is an issue because it affects the fluid compression mechanism and reduces your machine's ability to transfer power.

Therefore, keeping your hydraulic equipment clean is a critical part of machine maintenance. Make sure the hydraulic fluid you choose is compatible with your hoses, seals, and gearboxes. Compatibility prevents your fluids from foaming or releasing air during operation.

Preventing Corrosion

When servicing or repairing hydraulic cylinders, hoses, and pumps, you need to use fluids that prevent corrosion. Corrosion occurs when certain metals are exposed to oxygen (in the air), resulting in a chemical reaction.

Environmental conditions, such as humidity and salinity, also accelerate the corrosion process. The good news is that hydraulic fluids can reduce or prevent corrosion in multiple ways. For example, some fluids contain oxidation inhibitors. By forming a thin layer over the surface of exposed metals, these fluids increase the longevity of your hydraulic equipment.

Low viscosity is another useful feature when preventing corrosion. If the fluid isn't easily washed away in harsh environments, your machine will remain protected for longer.

Choosing the wrong hydraulic fluid can lead to a wide range of problems with your equipment. Make sure your fluids are capable of regulating temperature, preventing corrosion, and filtering debris from your system. Your machines' environmental conditions and working requirements will also determine which hydraulic fluid you choose.

Important Features to Look for in a HYVA Hydraulic Cylinder

Mon, 28 Feb 2022 19:55:34 GMT

HYVA cylinders are critical components of any construction project. Whether you use dump trucks for cement or underbody cylinders for waste management, choosing the right HYVA cylinder can significantly boost efficiency.

There are many options available in today's market. Some hydraulic cylinders come in lighter and faster designs, cutting down process times and reducing costs. Other cylinders come packed with smart features to automate movement and record real-time performance. So what are the top features to look for in a HYVA hydraulic cylinder?

Low Cylinder Weight

In the past, most cylinders weighed almost as much as the load they carried. The additional weight would exert pressure on hydraulic systems and increase operating costs. But thanks to modern designs, you can install low-weight cylinders that provide more headroom for load capacity.

Lighter cylinders are excellent options for tipping systems. Low-weight cylinders exert less pressure on the chassis bracket, resulting in a lighter, faster, and more flexible hydraulic system. Low weight hydraulic cylinders also have a greater degree of rotation, allowing you to access tight spots without compromising on safety.

Tipping Capacity

Higher tipping capacity is another important feature of HYVA systems. Constructions sites with more tipping capacity enjoy higher productivity and reduced project timelines. To increase capacity, you need hydraulic cylinders fitted with robust tipping valves.

Tipping valves use either mechanical or electrical systems to control cylinder movement. By installing the correct valves to match your hydraulic cylinders, you'll have more control over speed, rotation, and carrying capacity. Modern control valves also come in compact, easy-to-install designs. The tight fit saves space and reduces the likelihood of fluid leaks.

Smart Technology Capability

Smart technology has revolutionized many different industries, including construction. If you're not familiar, smart devices collect and transmit information in real-time, and the most common devices consist of sensors fitted on your hydraulic equipment. These sensors record performance metrics such as load weight, tipping angles, and fluid temperatures.

If you notice any changes to the operating environment, you can catch the problem early and schedule maintenance. HYVA hydraulic cylinders fitted with smart tools are essential in boosting productivity.

Proper sealing

When shopping for a HYVA hydraulic cylinder, consider models with excellent sealing. Proper sealing prevents oil leaks even in harsh operating environments. For example, construction projects scheduled during the winter will require front-end and underbody cylinders less prone to leaking.

Oil leaks increase operational costs and result in greasing and environmental degradation. Make sure your HYVA cylinders come with high-quality sealing technology. When combined with low fluid requirements, you can reduce material costs without affecting your carrying capacity.

ISO 9001 compliance

Last but not least, ensure that your HYVA hydraulic cylinders are ISO compliant. ISO 9001 is the specific standard that governs control and quality management systems. Because ISO requires proper documentation, you can be reassured that the hydraulic system meets essential performance metrics and your clients will be more confident in your ability to deliver quality and reliable services.

ISO-certified cylinders are capable of flexible unloading patterns, such as sideways and rear unloading. You will also have access to greater lifting capacity and premium build quality.

Purchasing the right HYVA hydraulic cylinder can be challenging. There are many features and options to choose from, so make sure you select what fits the requirements of your construction site. With the features outlined above, you'll be able to leverage the best cylinder technologies while increasing your load capacity. Furthermore, you can reduce costs and expand operational flexibility.

4 Types of Hydraulic System Tests to Keep Machines Running Smoothly

Fri, 28 Jan 2022 23:07:05 GMT

The pressure and materials in hydraulic machines creates the need for maintenance and service to ensure they run properly. Testing is an essential part of your company's hydraulic use. Proper testing will ensure the systems run for years, and you avoid major disasters that could lead to operation downtimes or full replacement.

Hydraulic testing breaks down into several categories. Learn about each form of testing and understand what testing is necessary for your company to thrive.

1. Water Tests

Hydraulic systems may include a wide variety of liquids with the machines. When you perform initial tests on equipment, one of the more basic elements is water. When equipment leaks or spills, simple water is much easier to clean up than oils or chemicals. A water test is essential for testing the pressure and leaks within a hydraulic system.

Water leaks are easy to spot with special testing equipment. Testing companies can track the location of the water leak and follow pressure measurements that may indicate when a problem has occurred. When water is used, technicians can easily add more, increase pressure, and see the performance.

They can make adjustments and fully drain the water without the need to worry about proper disposal or exposure to excess chemicals.

2. Repair Tests

When repairs are necessary on a hydraulic system, you shouldn’t just replace the part that the system needs and continue operations. Any major change requires testing. A testing company can inspect the repairs and ensure the parts are installed properly before the testing even begins. You do not want more damage to occur if a part is not installed correctly.

Testing tools can also check to ensure the longevity of the repair. You do not want a new part or function to simply act like a bandage on the whole system. Different tests will focus on the longevity of a repair and ensure the repair can last for the long haul. If the tests do not warrant optimal results, then you may consider other options like full machine replacements.

3. Start-Up Tests

If you have purchased all new equipment or started a whole new company, then start-up tests are ideal. Before operations are up and running, full testing is essential. The reports will detail the performance of machines and ensure everything operates smoothly. The testing process requires a minimal crew.

The last thing you likely want to worry about is hiring employees, starting operations, and then shutting down again due to errors. You will end up wasting a lot of time and resources. The start-up tests you run will often be in the early days of the machines. If any major problems occur, you will likely have coverage through parts and labor warranties if they apply to your equipment.

4. Test Standards and Optimization

Every now and then, consider tests for machines even if they operate smoothly. The hydraulic machines you have may run, but their performance may not be up to the typical standards. Testers have data and a set of standards for which the machines should reach. Many are from the National Fluid Power Association (NFPA) Standards for equipment.

From the standards, test technicians can offer recommendations for improvement. With some improvements, your system can operate more efficiently and use fewer energy resources. Recommendations may include simple repairs or system tweaks that require no repairs at all. The tests can make a big difference in your overall operations.

4 Common Causes of Hydraulic System Problems

Fri, 28 Jan 2022 23:03:23 GMT

Hydraulic systems can develop a variety of problems. Some problems make a system fail completely. However, some might not be so obvious initially but could cause a dip in performance or lead to later breakdowns. What are some common hydraulic system problems you should look out for?

1. Hydraulic Fluid Problems

The fluid in your system needs to be in optimum condition for your hydraulics to work. Problems like fluid contamination affect performance. For example, air, water, or foreign particles can contaminate hydraulic fluids and prevent them from flowing smoothly.

Air in your system can lead to problems such as cavitation and aeration. If you have cavitation problems, then excess internal air can cause a series of tiny implosions that can damage seals and parts. Aeration typically happens if air comes into your fluid from outside your system. These bubbles can also do some damage as they move through the system.

While both cavitation and aeration involve excess air, they sometimes give you different warning signs. For example, if you have cavitation problems, then your system usually makes whining sounds, while aeration often sounds more like a bang or loud knock.

Incoming water from leaks or internal condensation can also cause problems. Over time, this moisture can damage internal parts. Typically, you can see the effects of water ingress in your fluid, causing it to turn a milky color if water has contaminated it.

You can also run into problems if your fluid levels aren't right or if you use the wrong fluid for the system's job. If you don't have enough fluid in your system, then you won't get the right flow rates, which can put stress on your system, causing it to overheat and break down. If you aren't using the right type of fluid for a job, then you won't get the right results.

2. Changes in Temperature

Hydraulic fluids need to operate at a specific temperature. Each fluid will have an optimum range within which it flows at the right rate and viscosity. If the temperature in your system is too high or too low, then your system can't work at optimum efficiency.

For example, if your hydraulic fluid gets too hot, then it will lose some of its viscosity. It will start to thin out. If a fluid is thinner than it should be, it might not be able to lubricate key parts. It might flow too fast to do its job efficiently.

On the other hand, cold can make hydraulic fluids thicker than they should be. They won't be able to flow easily through the system. The system might suffer from stress damage if it has to work harder to keep its fluids moving at an acceptable rate.

3. Internal or External Leaks

Your hydraulic system needs to be sealed tightly. Both internal and external leaks allow fluids to leak out of the system. They also bring in contaminants, such as air and dirt.

While external leaks are often easy to see, internal leaks are harder to spot. Often, you don't know you have an internal leak until your system develops a cavitation, aeration, or temperature-related problem. For example, if your system slows down, then a leak might have reduced your fluid levels.

4. System Wear or Damage

Sometimes, hydraulic systems suffer from wear or damage. Factors such as cavitation, aeration, or temperature fluctuations can cause these problems. Sometimes, a part, such as a seal, valve, motor, or pump, simply wears or breaks due to old age or a fault. While your system might still work, it might run slower or hotter than usual, or it might make unusual noises.

If your hydraulic system has a problem or if you haven't had it checked out for a long time, then contact Miller Hydraulic Service, Inc. We offer a full range of services including testing and diagnostics, repairs, and rebuilds.

2 Strategic Ways to Avoid Hydraulic Emergencies

websitebuilder@thryv.com — Tue, 26 Oct 2021 15:07:53 GMT

Hydraulic systems are dynamic machines with many moving parts. Often, one bad component can affect an entire system and lead to inefficiency or unnecessary downtime. An emergency that shuts down workflow can be costly when production ceases or even dangerous if nearby operators receive injuries.

Fortunately, hydraulic emergencies can be preventable. The right knowledge enables operators and other workers to spot a problem before it worsens. Learn more about these two strategic ways to avoid hydraulic emergencies.

1. Avoid Contaminants

Contaminants like dirt and water within a hydraulic system can ruin closely fit moving parts and cause clogs or leaks that jeopardize efficiency. Consider the following simple habits that keep invasive contaminants from entering and harming a system.

Inspect Oil Daily

Sometimes, oil will adopt a milky or foamy appearance from the introduction of air. Unfortunately, air inside a system means the presence of moisture, which becomes obvious after a system cools. Condensed air mixes with oil, and the resulting milky appearance means water contamination is present.

Use Correct Filters

Around 70% of hydraulic failures are from contaminants. If a filter is not the proper size and fit, your system could become part of this statistic. Remember, filters are rated for both particle size and dirt-holding capacity. Your filter may allow smaller particles to escape even though it can hold a higher weight of larger particles.

Be mindful of your actual system run time when you consider the manufacturer's recommended filter maintenance. You may need to change filters on valves, actuators, and pumps more often if you run your hydraulic system 24/7 rather than eight hours per day.

Keep Clean

Operator and maintenance staff may unintentionally introduce contaminants into new, clean oil. You can avoid this by adopting the mantra to keep clean. For example, the need to change or check oil levels often allows dirt to enter. Clean the area first around hydraulic filters, fill plugs, and dipsticks before their removal to keep contaminants out.

Only pour from the original container into the system. Then, tightly seal stored oil containers to prevent the entry of contaminants.

2. Avoid Hose Failure

Much like human veins and arteries, hydraulic hoses perform similar tasks as they deliver fluids throughout key hydraulic machine components. Failing hoses cannot distribute necessary fluid, which can lead to limited efficiency and loss of production. Even worse, a sudden or unexpected hose failure releases highly pressured fluids that may be toxic or hot.

Several conditions may lead to hose failure.

Insufficient Insertion Depth

Poorly joined hose assemblies can cause a fitting to suddenly blow off. This dangerous scenario may lead to a swiftly whipping hydraulic hose with the potential to waste fluid, make a slippery mess, and spray nearby workers. Instead, fully push in fittings to meet the recommended insertion depth.

Dirty Assembly

Contamination that enters a hydraulic hose assembly tends to abrade and weaken inside hose diameters, which later leak. This happens when tiny particles enter the hose as it is cut and then not properly flushed. Make sure inner hoses are very clean before fitting insertion, and securely cap ends to prevent further contamination.

Exterior Abrasion

Disproportionate friction during operation when hoses come into contact with other objects can make a hose appear noticeably worn. Sometimes, the protective outer cover is torn or reinforcement wiring is visible. Replace a badly deteriorated hose. Fortunately, strategically placed protective covers can protect new hoses from future damage from other objects.

Sometimes, the best maintenance plans fail to prevent a hydraulic emergency . Contact the experts at Miller Hydraulic Service, Inc., if you suspect your hydraulic system may be in need of an update.
