Common faults and troubleshooting methods of high-pressure cleaning pumps

1. Insufficient pressure: It may be caused by wear and leakage of the internal seals of the pump body, blockage of the water inlet pipe, blockage of the filter, insufficient power of the motor or engine, etc. The solution includes checking and replacing the seals, cleaning the water inlet pipe and filter, checking the working condition of the motor or engine and repairing or replacing it.
2. Too small flow: It may be caused by the small diameter of the water inlet pipe, blockage of the filter, wear of the impeller or plunger inside the pump body, blockage of the water outlet pipe, etc. The solution includes replacing the water inlet pipe of suitable diameter, cleaning the filter and the water outlet pipe, and checking and replacing the worn impeller or plunger.
3. Water leakage: It may be caused by damage to the pump body seal, loose connection of the inlet and outlet pipes, and rupture of the high-pressure hose. The solution includes checking and replacing the pump body seals, reconnecting and tightening the inlet and outlet pipes, and replacing the ruptured high-pressure hose.
4. Excessive noise: It may be caused by wear and looseness of the internal parts of the pump body, motor or engine failure, damage to the shock absorber, etc. Solutions include checking and replacing worn and loose parts, repairing or replacing motors or engines, and checking and replacing shock absorbers.
5. Equipment cannot start: This may be caused by power failure, switch damage, motor or engine failure, control system failure, etc. Solutions include checking the power supply, replacing damaged switches, repairing or replacing motors or engines, and checking and repairing control system failures.
