Preventative Maintenance for Hydraulic Systems

The longevity and reliable functioning of hydraulic systems require routine maintenance. Components such as pumps, valves, hoses, and cylinders are all subject to wear and tear over time. Hydraulic repair helps to minimize downtime, reduces repair costs, and ultimately extends the lifespan of your hydraulic system. Here are some preventative maintenance tips for your hydraulic systems:

Oil Maintenance

The oil in a hydraulic system acts as a lubricant, coolant, and energy transfer medium. It plays a role in supporting the smooth operation of the system. Regularly checking and changing your hydraulic oil can help prevent issues with your system. Over time, oil can become contaminated with dirt, debris, and water, which can lead to damage or malfunctioning of components. Professional hydraulic repair experts recommend routine oil maintenance as part of preventative upkeep for your hydraulic systems.

Filter Replacement

The filters in a hydraulic system are responsible for removing contaminants from the oil. Over time, these filters can become clogged and unable to filter out debris effectively. A clogged filter can lead to increased wear and tear on components, reduced system performance, and complete failure. Regularly replacing filters as part of your hydraulic maintenance routine can keep your system running efficiently and may help extend its lifespan.

Seal Replacement

Check for seal damage regularly and replace them immediately if any damage is found. Seals are responsible for preventing oil leaks and maintaining proper pressure within the system. Over time, seals can become worn or damaged due to exposure to high pressures, extreme temperatures, and harsh chemicals in the hydraulic fluid. Replacing damaged seals as part of your maintenance routine can prevent major issues such as oil leakage and system malfunctions. Inspect seals visually for any signs of cracking, wear, or damage. You can also use a seal puller to remove the seal and check for any deformities on the surface.

System Temperature 

Monitor and maintain the temperature of your system to avoid any potential issues. High temperatures can cause oil degradation, which can lead to decreased lubrication and increased wear and tear on system components. This can result in costly repairs and downtime for your equipment. Low temperatures can cause oil thickening and reduced flow, which can affect system performance. Check proportional valves and solenoid coils for any signs of overheating, as this can indicate a malfunctioning component that needs to be replaced. Regularly check the temperature of your system using an infrared thermometer or thermal imaging camera. 

Hydraulic Reservoir

The hydraulic reservoir acts as a cooling mechanism, removing excess heat generated during the operation of the system. Maintain the temperature within the optimal range to avoid potential issues that can lead to costly repairs and downtime. High temperatures can be caused by excessive friction, which can be minimized through proper lubrication and regular maintenance. The type of fluid used also plays a role in maintaining optimal temperature levels within the system. Contaminated or degraded fluid can result in increased friction and heat generation, leading to potential damage to components.

Rod Conditions

The rods are responsible for converting fluid pressure into mechanical force. As they move back and forth within their cylinders, friction occurs between the rod and its seal, generating heat. This heat can cause damage to both the rod and its seal if not properly managed. Regularly inspect the condition of the rods and take appropriate measures to maintain their optimal state. One common issue with rods is corrosion. Corrosion occurs when the metal surface of the rod is exposed to corrosive elements in the fluid or environment. Professional hydraulic repair shops can perform corrosion inspections and provide recommendations for remediation. 

Breather Caps 

Breather caps act as a vent for excess air and fluid, preventing damage to other components such as seals and valves. These caps also serve as a barrier against contaminants, keeping them out of the system. They are typically found on hydraulic reservoirs and tanks and can also be used in other fluid systems. Breather caps come in various designs and sizes to suit different applications. Some common types include twist-lock, pressure-relief, and desiccant breather caps. Twist-lock breather caps have a threaded design that allows for installation and removal. Pressure-relief breather caps have a built-in valve that opens when pressure exceeds a certain threshold, allowing air to escape. Desiccant breather caps contain desiccant beads that absorb moisture from incoming air. 

Keep Up With Any Hydraulic Repair Needs

Preventative maintenance for hydraulic systems can help extend the lifespan of your equipment and save you money on costly repairs. Regular checks for fluid contamination, corrosion, and breather cap functionality can help avoid downtime. By partnering with a professional hydraulic repair service, you may improve the performance and reliability of your hydraulic systems.
