What are the main parts of the maintenance of the pumping machine

The maintenance of the pumping machine is a very important part, which directly affects the service life and working efficiency of the pumping machine. The maintenance of the pump mainly includes the following aspects:

1. Daily maintenance

Check whether there is leakage in the pump body and pipeline: regularly check whether there is leakage in the pump body and pipeline connections, and tighten the bolts or replace the seals in time.

Check the bearing temperature: high bearing temperature may be a signal of poor lubrication or bearing wear.
Check the motor: check whether the motor is overheated, whether there is any abnormal noise, and keep the motor well ventilated.
Check vibration: whether there is any abnormal vibration when the pump machine is running, if there is excessive vibration, the reason should be checked in time.
Check the flow and head: Measure the flow and head of the pump regularly, compare with the rated value, and deal with the abnormality in time.
Lubrication: Regularly lubricate the bearings, mechanical seals and other parts of the pump in accordance with the requirements of the manual.
2, regular maintenance
Dismantling and inspection: dismantle the pump body regularly, check whether the impeller and guide parts are worn, corroded or blocked, and clean up sundries.
Cleaning the pump body: clean the inside of the pump body with water or cleaning agent to remove dirt.
Check the seal: check the wear and tear of the mechanical seal or packing seal, and replace them in time.
Check the motor winding: Check the insulation of the motor winding to ensure the safe operation of the motor.
Balance correction: For high-speed pumps, carry out dynamic balance correction regularly.
3, regular maintenance
Replacement of lubricating oil: Replace the lubricating oil regularly according to the instruction of lubricating oil.
Replace wearing parts: Replace wearing parts, such as bearings, seals, etc. regularly.
Conduct performance test: Conduct regular performance test to determine whether the pump performance is degraded.
4. Maintenance under special circumstances
Dry running: If dry running occurs in the pump, it should be shut down immediately for inspection and replacement of damaged parts.
Overload operation: If the pump is overloaded for a long period of time, the load should be reduced or the pump should be replaced with a more powerful one.
Cavitation: If the pump experiences cavitation, the piping system should be checked to ensure that there are no leaks in the suction line and to raise the suction level.
5. Factors affecting the life of the pump
Water quality: impurities in the water, corrosive substances will accelerate the wear and tear of the pump.
Operating conditions: frequent starting, stopping, overloading operation will shorten the life of the pump.

Maintenance: not performing maintenance on time will accelerate the damage of the pump.
