The 10 hp well submersible pumps always stop working after running for a while


1) Suction head too high
Troubleshooting method: Check the present net head. Pipeline at inlet too small or too long will cause great friction loss.
2) 10 hp well submersible pumps impeller or pipeline is clogged.
Troubleshooting method: check for obstacles.
3) The seal pad of the pump case is broken
Troubleshooting method: check the conditions of the seal pad and replace it as required.
3. The 10 hp well submersible pumps consume too much power
1) The pump rotates in a wrong direction.
Troubleshooting method: check the rotary direction.
2) The rotary parts get deadly stuck.
Troubleshooting method: check if the clearances of quick-wear parts inside the pump are normal.
3) Bend shaft
Troubleshooting method: correct the pump shaft or replace it as required.
4) Speed too high
Troubleshooting method: check the voltage of the motor windings or the turbine steam pressure.
5) Pump head is lower than the rated value.
Too much fluid is being pumped.
Troubleshooting method: consult the manufacturer.
Install a throttle, cut the impellers.
6) The fluid is heavier than the estimated weight.
Troubleshooting method: check the weight ratio and viscosity.
7) The stuffing box is not stuffed correctly, with insufficient stuff or stuff too tight, not put into the box in a correct way.
Troubleshooting method: check the stuff, refill the stuffing box.
8) The shaft bearing is not lubricated correctly or worn out.
Troubleshooting method: check and replace as required.
9) The clearance between the wear-resistant rings in operation is not correct.
Troubleshooting method: check if the clearance is correct.
Replace the pump case or wear-resistant ring as required.
10) The pump case bears too much pressure from the pipeline.
Troubleshooting method:
Eliminate the pressure and consult the manufacturer.
After eliminating the pressure, check the centering of the 10 hp well submersible pumps.
