Best Practices for Maintaining Hydraulic Motors

A hydraulic motor maintains force at constant rates and the torque without having a pump to supply added fluids to increase pressure. Hydraulic systems are safe, simple, and efficient power sources because they use fewer moving parts. However, having leakage in the system can cause inconvenience to a business.

Luckily, hydraulic maintenance can prevent problems like leakages and maximize the uptime of the hydraulic system. In addition, using a hydraulic operation provides convenience for management control, and you can use it for centralized control or automatic operation.

How To Maintain Hydraulic Motor

Here are a few tips on maintaining your hydraulic system to allow the hydraulic system to continue with optimal function.

1. Sample Your Oil

Regularly sample your oil for undesirable contaminants such as water, as it can help prevent the need for costly repairs in the future. Contamination is one of the main reasons why the hydraulic system can leak. As a result of the leakage, the hydraulic pumps can be blocked or accelerate the wear rate.

Take your oil for testing from a specific sample point to ensure consistency in measurement. Ideally, you are advised to take a sample from an active return line because testing from a stagnant source like a reservoir drain can result in inaccurate results.

2. Check Your Filter Indicators

A hydraulic filter indicator monitors the contamination caught by the filter. It displays the contamination level electrically, visually(using a pop-up indicator or a gauge), or both methods.

Consider replacing the filter when the indicator reads that it has reached its maximum acceptable contamination holding capacity. If left unmonitored, the filter can start leaking bypass fluid (if your hydraulic system was fitted with a bypass valve), making it vulnerable to more contamination.

Check that the gauge style indicator is working correctly, or check the indicator with cold oil for an early warning.

3. Test Performance

If the performance level of your hydraulic system is slowly decreasing, it could be a result of being used for a more extended period without proper maintenance. Swiftly declining performance can be a precursor for catastrophic hydraulic system failure.

Closely monitor your system’s oil and temperature levels, actuator speed, and case drain flow to predict failure in one of the systems. This will help prevent expensive repairs of the failed parts in the future.

4. Measure the Temperature Levels

Temperature levels on your hydraulic system can adversely affect your oil’s viscosity. If your oil is above the normal working range of the system’s components, it can reduce its lifespan.

For example, high viscosity can result in a temperature drop in the suction lines leading to cavitation. On the other hand, low viscosity reduces the thickness of the film’s consistency between the components, resulting in wear and tear.

5. Maintain Cleanliness on Your Equipment

Knowing how to clean hydraulic motor parts is very important if you want yours to last long. Grime and dirt are generally harmless on the exterior of your equipment. However, it puts the internal parts at risk of being contaminated. Contaminants can enter the system when the hydraulic components are disconnected for relocation or maintenance during an oil change or replacing the filter system.
