we provide advice of submersible pump installation,submersible pump working,submersible pump troubleshooting,submersible pump stopped and other pump technology articles.
1. Fault: IH chemical pump does not absorb water, the pressure of the table violently beating.
Reason: the diversion of water is not enough. Inner air pump. Water suction pipe and pipe leakage.
Solution: irrigation water diversion. Check the pipeline to eliminate the leakage phenomenon.
2. Fault: flow rate is lower than the design flow.
Reason: impeller plug. Seal ring gap wear is too large. Speed is not enough.
Solution: remove blockage. Replace sealing ring. Increase the speed to the nameplate of the specified value.
3. Failure: IH chemical pump outlet pressure gauge pressure, the pump water is little or no water.
Reason: pipe resistance. Turn right. Impeller blockage. Speed is not enough.
Solution: reduce pipe resistance. Check motor turn. Remove the impeller plug. Increase speed.
4. Fault: vacuum table indicates a high degree of vacuum, IH chemical pump is still not water.
Reason: the valve does not open or blocked. Suction pipe resistance. Suction height is too high.
Solution: check valve valve flexibility, remove the blockage. As far as possible to make the water pipe is simple. Reduce the height of water absorption.
5. Fault: IH chemical pump consumes too much power.
Reasons: packing too tight, packing room heating. Impeller wear. Pump water supply is too large.
Solution: relax the packing gland. Replace impeller. Close small gate valve, reduce the flow.
6. Fault: IH chemical pump abnormal sound, no water pump.
Reason: water absorption tube resistance is too large. Too high water absorption. Air into the water absorption pipe. Pumping liquid temperature is too high.
Solution: check whether the water pipe is blocked. Clean the valve, reducing the temperature of the liquid or lower the height.
7. Faults: pump vibration
Reason: pump shaft and motor shaft is not concentric. Impeller imbalance. Bearing clearance is too large.
Solution: adjust the pump and motor to align the axis. Impeller through the balance test, unbalanced weight requirements in about 3 grams. Replace bearing.
8. Fault: bearing heating
Reason: the bearing is short of oil or oil viscosity is too big influence lubrication. Bearing wear clearance is too large. Pump and motor are not concentric.
Solution: come on. Good oil or small viscosity oil. Replace bearing. Adjust pump and motor to ensure concentric.
9. Faults: large noise
Reason: pump and motor installation is not concentric. Pump or motor bearing wear, resulting in beating.
Solution: adjust the pump and motor, to ensure that the. Replace new bearing.
