Hydraulic Pump Maintenance: Key to Ensuring Equipment Stability

As the core component of a hydraulic system, the operational condition of a hydraulic pump directly affects the performance of the entire system. Mastering hydraulic pump maintenance techniques is crucial for ensuring equipment stability.

Common hydraulic pump failures mainly include insufficient pressure, reduced flow, abnormal noise, and excessive temperature. These failures are usually caused by seal wear, bearing damage, distributor plate scratches, or piston sticking. Maintenance personnel need to accurately identify the root cause based on the symptoms.

Hydraulic pump maintenance must follow standardized procedures: first, disconnect the power and release system pressure, then disassemble the pump body and clean all components. Special attention should be paid to the wear of key parts such as pistons, distributor plates, and bearings during inspection. Parts that exceed wear limits must be replaced promptly, and the assembly must ensure that the fit clearance of each component meets technical requirements.

Preventive maintenance is key to extending the service life of hydraulic pumps. Regularly replace hydraulic oil and filters to maintain oil cleanliness; monitor system pressure and temperature to detect abnormalities in a timely manner; conduct daily inspections and pay attention to changes in pump vibration and noise. Through scientific maintenance, the failure rate can be effectively reduced, and equipment service life can be extended.

Mastering hydraulic pump maintenance techniques not only enables timely troubleshooting but also reduces equipment failure rates through preventive maintenance, creating greater value for enterprises.
