What are the general faults of water pumps? How to maintain it?

The water pump may have the following faults:

The pump can't start or stop immediately after starting: it may be caused by power failure, motor damage, rotor stuck or internal blockage of the pump body.

Maintenance method: check the power supply circuit and motor, clean the pump body and rotor, and eliminate problems such as blockage and jamming.

Abnormal noise or vibration when the pump is running: it may be caused by bearing damage, impeller damage or foreign matter entering the pump body.

Maintenance methods: replace the bearing or impeller, clean the inside of the pump body, remove foreign objects, etc.

Decrease of pump flow or head: It may be due to abrasion of impeller, fouling in pump body or failure of mechanical seal.

Maintenance method: replace the impeller, clean the inside of the pump body and replace the mechanical seal.

Water leakage or seepage in the pump: it may be caused by mechanical seal failure, seal aging or pump body damage.

Maintenance method: replace mechanical seal, replace seal or repair damaged parts of pump body.

Cavitation phenomenon of pump: It may be caused by low water level of water source, blockage of water inlet pipeline or gas during pump operation.

Maintenance methods: adjust the water level of the water source, clean the water inlet pipe, check the tightness, exhaust, etc.

In a word, when maintaining the water pump, corresponding maintenance methods should be taken according to different fault causes to ensure that the water pump can work normally and maintain long-term stable operation effect. If you are not sure how to maintain it, you'd better ask professional water pump maintenance personnel to check and handle it.
