Troubleshooting & Maintenance Tips
Basic Troubleshooting for Hydraulic Pump Issues:
Low Pressure/Slow Speed: Check hydraulic fluid level, ensure filters aren't clogged, inspect for leaks, or suspect internal pump wear.
Noise: Could indicate cavitation (air in the system, low fluid), worn bearings, or internal damage.
Overheating: May be caused by low fluid, clogged cooler, internal leakage within the pump or system components, or operating with too high viscosity fluid.
Maintenance Tips for Prolonging Pump Life:
Regularly inspect and maintain clean hydraulic fluid at the correct level. Contaminated fluid is a major cause of pump failure.
Adhere strictly to the manufacturer's schedule for replacing hydraulic filters.
Inspect all hydraulic hoses and fittings for leaks or damage. Address any leaks immediately.
Monitor system temperature and pressure regularly using gauges. Abnormal readings can indicate impending problems.
Ensure proper system bleeding after replacing components to remove trapped air.
Note: Complex hydraulic issues require diagnosis by qualified personnel.
