When the pump is running, it is treated as the following method:
Cause of failure :
1.Foundation bolt loose or installation is not perfect;
2.Pump and motor installation is not concentric;
3.Into the air or the occurrence of cavitation;
4.Pump bearing damage or wear;
5.The remaining air outlet;
Elimination measures ：
1.Tighten bolts, improve the basic installation;
2.Correction of the concentric degree;
3.Find out into the air causes and take appropriate measures to eliminate, the occurrence of cavitation is decreased water absorption height to reduce the head loss of water absorption;
4.Replace or repair the bearing;
5.In the remaining air, the installation of exhaust facilities;
When the pump is running, the motor is treated according to the following methods:
Cause of failure ：
1.Speed is too high;
2.Pump flow is too large;
3.Pump into the foreign body;
4.Motor or pump mechanical loss is too large;
Elimination measures ：
1.Check whether the motor is complete;
2.Close the gate;
3.Remove the foreign body;
4.The gap between the inspection of pump impeller and pump casing, pump stuffing, pump shaft, pump bearing is normal;
