Fault | Cause | Troubleshooting method |
Water pump does not discharge water |
1.No or insufficient liquid storage is added to the pump casing | 1.Add enough liquid storage |
2. Air leakage in the suction pipeline | 2.Check and eliminate air leakage phenomenon | |
3. The speed is too low | 3.Adjusting the speed | |
4. The suction head is too high or the suction pipeline is too long | 4.Reduce suction head or shorten suction pipeline | |
5. Excessive mechanical seal leakage | 5.Repair or replace | |
6.The gas in the suction pipeline cannot be discharged from the outlet | 6.Discharge the gas | |
Excessive noise and vibration |
1.Unstable footing | 1.Reinforce the footing |
2.Pump shaft bending | 2.Replace or correct | |
3.Cavitation | 3.Adjusting working conditions | |
4.Severe bearing wear | 4.Replace it | |
5.There are debris in the inlet pipeline | 5.Remove debris | |
6.The main shafts of the pump and engine are not concentric | 6.Adjusting coaxiality | |
Insufficient water output |
1.The impeller channel and suction pipe are blocked | 3.Insufficient power or low speed |
2.Impeller or impeller seal severely worn | 2.Replace the impeller or impeller seal | |
3.Insufficient power or low speed | 3.Add sufficient power and adjust to the rated speed | |
Excessive shaft power consumption |
1.Excessive water flow rate | 1.Increase outlet pressure |
2.Speed too high | 2.Reduce appropriately | |
3.Pump shaft bending or impeller jamming | 3.Transformation or correction | |
4.The flow channel inside the pump is blocked or stuck | 4.Remove blockages |
