Common faults of electric cold water high pressure cleaning machines
Common faults of electric cold water high pressure cleaning machines
Electric cold water high pressure cleaning machine
Failure phenomenon I. Insufficient pressure of the outflow water
Cause of failure / Treatment
1. The water supply pipe leaks, find the leak and reinforce it.
2. The tap water supply is inadequate, the inlet pipes are sucked up and the water is supplied by large storage containers
3. The inlet filter is blocked, replace the inlet filter (cleaning)
Failure phenomenon II. The outflow pressure is insufficient and the inflow low pressure pipe is trembling very badly
Electric cold water high pressure cleaning machine
Cause of failure / Treatment
The inlet one-way valve is damaged / ageed; Replace the inlet one-way valve
Failure phenomenon III. The outflow pressure is insufficient and the outflow high pressure pipe shakes very badly
Cause of failure / treatment method
1. Drainage / aging of the pump valve Replace the pump valve
2. Damage to the pressure valve pin Replace the pressure valve tip
Failure phenomenon IV. The outflow pressure is insufficient, and the pressure valve emits a "dying" noise
Cause of failure / treatment method
Electric cold water high pressure cleaning machine
1. Nozzle blockage Remove nozzle / high pressure pipe
2. The pressure spring inside the pressure valve breaks / ages Replace the pressure spring inside a pressure valve
Fault phenomenon five, mud relief valve leakage
Cause of failure / treatment method
1. The pressure exceeded the maximum pressure range of the equipment and the nozzle was blocked. Check the pressure on the pressure gauge and drain the nozzle
2. Mud relief valve internal pressure spring broken / aged. Replace mud relief valve pressure spring
3. Mud relief valve thimble damaged. Replace mud relief valve thimble
Failure phenomenon VI. The entire machine is not powered
Electric cold water high pressure cleaning machine
Cause of failure / treatment method
1. Emergency stop switch not on clockwise turn emergency stop switch
2. The power key is broken. Replace the key switch
3. Earth leakage protection switch to open, or fuse Reset earth leakage protection switch, check whether there is a short circuit, replace the fuse
Failure phenomenon 7. The motor does not start
Cause of failure / treatment method
1. The outlet pressure switch is damaged / stuck Fix / replace the outlet pressure switch
2. Soft starter damage Replace / reset a soft starter
Electric cold water high pressure cleaning machine
3. Electrical contactor damaged. Replace contactor
Failure phenomena VIII. Equipment frequently starts or shuts off without stopping
Cause of failure / treatment method
1. Water leaks from a pressure gun or tube Replace a pressure shot or tube
2. The pressure switch is broken or the shut-off delay relay is broken Replace the pressure switch or the delay relaying relay
3. The water one-way valve at the front end of the pressure valve is stuck or the pressure valve broken Clean the water one-ways valve or replace the pressure valve
