As the "heart" of a hydraulic system, the proper operation of a hydraulic pump directly affects the efficiency and safety of the entire equipment. To ensure long-term stable operation and extend the service life of the hydraulic pump, the following precautions should be taken during use:
I. Pre-Startup Checks
Fluid Inspection:
Check whether the hydraulic oil level is within the specified range on the oil gauge. If insufficient, promptly add clean hydraulic oil of the same grade.
Check whether the hydraulic oil is clean and free of impurities, moisture, or other contaminants. Replace the oil if necessary.
Select the appropriate hydraulic oil viscosity based on the ambient temperature to avoid affecting the pump's normal operation due to excessively high or low viscosity.
Seal Inspection:
Check for leaks at the pump body, pipelines, joints, and other parts. Tighten or replace seals as needed.
Ensure the tank vent is unobstructed to prevent pressure changes in the tank from affecting the pump's oil suction.
Connection Inspection:
Check whether the connections between the pump, motor, and coupling are secure and reliable to avoid vibration or noise caused by looseness.
Verify that the inlet and outlet ports are correctly connected to prevent reverse rotation and damage to the pump.
Other Inspections:
Check whether the electrical wiring is correctly connected and whether the voltage is stable.
For hydraulic pumps that have been idle for a long time, manually rotate the pump shaft before startup to ensure smooth rotation.
II. Monitoring During Operation
Pressure Monitoring:
Closely monitor system pressure changes to avoid excessively high or low pressure.
Excessive pressure can overload the pump and damage internal components, while low pressure can affect system performance.
Temperature Monitoring:
Monitor the hydraulic oil temperature to prevent overheating.
High oil temperature accelerates oil aging, reduces lubrication performance, and may even cause pump damage.
Noise and Vibration Monitoring:
Pay attention to the pump's operating sound and observe its vibration.
Abnormal noise and vibration may indicate internal component wear, looseness, or other faults.
Leakage Monitoring:
Regularly check for leaks at the pump body, pipelines, joints, and other parts, and address them promptly.
III. Maintenance
Regular Replacement of Hydraulic Oil and Filters:
Replace hydraulic oil and filters regularly based on usage to maintain oil cleanliness.
When replacing hydraulic oil, thoroughly clean the oil tank and pipelines.
Regular Inspection of Seals:
Regularly inspect seals at the pump body, pipelines, joints, and other parts, and replace aged or damaged seals promptly.
Regular Cleaning of the Oil Tank:
Record Keeping:
IV. Other Precautions
Avoid Prolonged Overload Operation:
Avoid Frequent Startups and Stops:
Professional Repairs:
Summary:
Proper use and maintenance of hydraulic pumps are crucial for ensuring the normal operation of equipment. By strictly adhering to the above precautions, the service life of the hydraulic pump can be effectively extended, equipment efficiency improved, failure rates reduced, and production safety ensured.
