Common faults and treatment methods of boiler feedwater pump
1. Power supply issue. Check if the power connection is normal and ensure that the power voltage is stable.
2. The pump body is leaking water. Replace the seal or adjust the installation position.
3. The pump shaft is bent. Check if the pump shaft is bent. If so, please replace or correct.
4. Bearing damage. Replace bearings and strengthen lubrication management.
If the pump wheel comes off, reinstall the pump wheel or replace the nut.
6. Motor malfunction. Check the power supply voltage, clean the motor radiator, or replace the motor bearings.
7. The water pump does not absorb water or the pressure is insufficient. Check if the intake pipe is unobstructed, clean or replace the intake pipe to ensure that the intake pressure meets the requirements.
8. The water volume is lower than expected. Clean the water pump and pipeline, replace the sealing ring, and increase the speed of the water pump shaft.
