High pressure cleaning machine equipment is a very important industrial cleaning equipment, a wide range of use, sanitation, pipeline and industrial cleaning will be used, but the high pressure cleaning machine in the long use process will inevitably appear some failures, how to solve these common failures?
Fault 1. Air leakage in the water supply pipe of the high pressure washer: find out the leakage point and reinforce or replace the water supply pipe; Insufficient tap water supply, the intake pipe is sucked flat: use large water container water supply; The water inlet filter element of high pressure cleaning machine is blocked: replace the water inlet filter element or solve the filter element blockage;

Fault 2. The water outlet pressure is insufficient and the inlet low pressure pipe jitter seriously. The check valve of the inlet pipe of the high pressure washer is damaged or aging. The pressure regulating valve thimble of the pressure cleaning machine is damaged: Replace the pressure regulating valve thimble;

Fault 3. The water pressure is insufficient, and the pressure regulating valve makes "dada" noise. The nozzle of high pressure cleaning machine is blocked: dredge the nozzle and dredge the high pressure pipeline; Pressure regulating valve internal pressure spring fracture/aging: replace the pressure regulating valve pressure spring;

Fault 4, the leakage pressure of the safety valve exceeds the pressure range of the equipment, the nozzle is blocked: check the pressure of the pressure gauge, dredge the nozzle; Safety valve internal pressure spring fracture/aging: replace the valve pressure spring; The safety valve thimble of the high pressure cleaning machine is damaged: replace the safety valve thimble;

Fault 5. The emergency stop switch of the high pressure cleaning machine is not opened: turn the emergency stop switch clockwise; The power key of the pressure washer is damaged: replace the key switch; Leakage protection switch pop up: reset the leakage protection switch, check whether short circuit, replace the fuse; Pressure cleaning machine burst fuse: replace the fuse; Socket wiring contact is poor: plug the socket tightly;

Failure 6. The water outlet pressure switch is damaged/stuck after the motor does not start: repair/reset the water outlet pressure switch; If the soft starter of the pressure washer is damaged, replace or reset the soft starter. The motor contactor of the pressure washer is damaged: replace the contactor;

Fault 7. The high pressure gun or water pipe leaks when the equipment starts frequently or shuts down continuously: replace the high pressure gun or water pipe; Pressure switch or delay relay damage: replace the pressure switch or delay relay; If the front water check valve of the pressure regulating valve is stuck or damaged, clean the water check valve or replace the pressure regulating valve. Bad contact of power supply, terminal board or socket: press the socket tightly; The pressure in the pressure gun of the pressure washer is not completely released: Hold the trigger of the water gun to release the pressure in the pump. High pressure washer equipment in the long-term use of the process to encounter more problems is insufficient pressure, safety valve water leakage and the machine is not powered on and other problems, in fact, these problems are not difficult to solve, as long as we have enough understanding of the equipment can be a good solution to such problems.
