- Product Details
- Applicable Scene
After completing a visual inspection, assess the hydraulic pump itself. Check for signs of wear, such as:
ER-R-130B-LS-25-20-NN-F-3-S2CP-A1N-AAA-NNN-NNN

Cavitation Damage: Look for pitting on the pump components, which may indicate cavitation due to inadequate inlet pressure.
Bearing Condition: Ensure that the bearings are in good condition and properly lubricated.
Measure Pressure using a Gauge
To diagnose pressure loss accurately, use a pressure gauge. Connect the gauge to the hydraulic system at different points, including before and after the pump, to identify where the pressure drop occurs. This will help pinpoint whether the issue lies within the pump, the hoses, or the control valves.
Analyze Fluid Viscosity and Contamination
The viscosity of hydraulic fluid plays a crucial role in system performance. Check the fluid specifications and ensure that the fluid is at the correct viscosity level. Additionally, analyze the fluid for contamination by performing a fluid analysis or using a particle counter. Contaminated fluid can cause increased wear and reduced efficiency.
Inspect Control Valves
Control valves regulate the flow and pressure of hydraulic fluid in the system. Malfunctioning valves can lead to pressure loss. Ensure that all valves are functioning correctly, and check for sticking or leaks around the seals. Replace any faulty valves as needed to restore proper function.
Testing Relief Valves
Relief valves protect the hydraulic system from excessive pressure. If the relief valve is stuck open or set incorrectly, it may cause pressure loss. Test the relief valve functionality and adjust the pressure settings according to manufacturer specifications.
Conclusion
Troubleshooting hydraulic pump pressure loss requires a systematic approach that involves visual inspections, pressure measurements, and component evaluations. By identifying the symptoms and root causes, maintenance personnel can take corrective actions to restore pressure and enhance system performance. Regular maintenance, including timely fluid changes and component inspections, can also prevent future pressure loss, ensuring the longevity and effectiveness of hydraulic systems in industrial equipment.
