Water pumps are a more common mechanical and equipment in industrial water. After a long period of use, the pump may have some problems. Common faults include leakage, water, noise, vibration, etc. The cause and processing method of the pump will be explained below. I hope that users will help in the future.

Pump

Vibration caused by motor problems

Failure judgment: Check whether the vibration of the motor is higher than the vibration of the pump or just the motor vibration.

Processing method: Maintenance motor or replacement motor.

Vibration caused by steam erosion

Failure judgment: There is an abnormal sound in the pump, which is the sound of rubbing in the pump in the pump.

Treatment method: Clear the sand and stones in the pump to solve the vibration problem.

Vibration caused by the coupling

Failure judgment: Disassemble the pillar sales, and measure whether the distance between the pump connection and the pillar pillar sales hole is consistent.

Treatment method: replace the coupling and column sales.

Vibration caused by rotor wear

Failure judgment: After the pump runs for a long time, the flow decreases, the current will rise, and the pressure will be down.

Processing method: After the pump is disintegrated, check the gaps and wear of the leaf wheels, mouth, leaf cover, and throwing device in turn. The gap needs to be replaced higher than 1 mm. The axis beating is higher than 0.08 mm. Can be repaired.
