Fault

reason

Corrective Action

1. The water pump does not absorb water, and the pointers of the pressure gauge and vacuum gauge jump violently.

There is not enough water injected into the water pump, and the water inlet pipe is leaking.

Continue to pour water and try to plug the leaks.

2. Flow decreases or Head decreases.

1) The water pump or inlet and outlet pipes are blocked.

2) The sealing ring or impeller is seriously worn.

3) Speed ​​is lower than the specified value.

1) Clean the pump or pipeline.

2) Replace damaged parts.

3) Adjust to rated Speed.

3. The power of the water pump shaft is too large

1) Flow exceeds the usage range

2) Mechanical friction occurs.

1) Adjust Flow to operate within the specified range.

2) & nbsp; examination of causes of wear and tear for elimination.

4. The sound inside the water pump is abnormal, the water pump cannot suck water or the pump vibrates.

1) The water suction height of the pump is too high, the resistance of the water suction pipe is too large or the flow water is too large.

2) The water suction pipe is leaking.

3) The pump and the Motor shaft are not concentric.

4) Some parts have loose screws.

1) Reduce the water suction height, reduce the resistance of the water suction pipeline, or adjust the water outlet valve to reduce flow.

2) Eliminate air leakage.

3) The adjustment result is concentric with the Motor axis.

4) Tighten the screws.

5. The bearing is overheated.

1) There is too much or insufficient lubricating oil, or it has deteriorated.

2) The pump shaft and the Motor shaft are not concentric.

1) Add oil or change oil.

2) Adjust the pump to be concentric with the Motor shaft.
