High pressure cleaning machine common faults and solutions

High pressure cleaning machine equipment is a very important industrial and commercial cleaning equipment, a wide range of use, sanitation, pipeline and industrial cleaning will be used, but the high pressure cleaning machine in the long-term use of the process will inevitably appear some failures, these common failures to solve it?

Fault 1. Insufficient water pressure
Leakage of the water supply pipe of the high pressure cleaning machine: find out the leakage point to re-strengthen or replace the water supply pipe; Tap water supply is insufficient, the inlet pipe is sucked flat: use large water containers for water supply; The water inlet filter block of the high pressure cleaning machine: replace the water inlet filter or solve the filter block.

Fault two, the outlet pressure is insufficient, and the inlet low pressure pipe shakes seriously
The check valve of the water inlet pipe of the high pressure cleaning machine is damaged or aging: Replace the water inlet check valve; The pressure regulator thimble of the high pressure cleaner is damaged: Replace the regulator thimble.

Fault three, the water pressure is insufficient, and the pressure regulator makes a "rattling" noise
High-pressure cleaning machine nozzle blockage: dredge nozzle, dredge high pressure pipeline; Rupture/aging of the pressure spring inside the regulator: Replace the pressure spring of the regulator.

Fault four, safety valve leakage
The pressure exceeds the pressure range of the equipment, and the nozzle is blocked: check the pressure of the pressure gauge and dredge the nozzle; Fracture/aging of the internal pressure spring of the safety valve: Replace the pressure spring of the safety valve; If the safety valve thimble of the high pressure cleaner is damaged, replace the safety valve thimble.

Fault five, the whole machine is not powered on
The emergency stop switch of the high pressure cleaning machine is not opened: turn the emergency stop switch clockwise; The power key of the High Pressure Washer is damaged: replace the key switch; The leakage protection switch pops up: reset the leakage protection switch, check whether it is short circuit, and replace the fuse; High pressure cleaning machine burst fuse: replace the fuse; Socket cable contact is poor: plug the socket tightly.

Fault six, the motor does not start
The outlet pressure switch is damaged/stuck: repair/reset the outlet pressure switch; The soft starter of the high pressure washer is damaged: replace/reset the soft start; The motor contactor of the high pressure washer is damaged: Replace the contactor.

Fault seven, frequent startup or non-stop shutdown
High-pressure gun or high-pressure water pipe leakage: Replace the high-pressure gun or high-pressure water pipe; Pressure switch or delay relay damage: Replace the pressure switch or delay relay; If the front outlet check valve is stuck or damaged, clean the outlet check valve or replace the pressure regulator. If the power supply, patch board or socket is in poor contact, press the socket tightly. The pressure in the high pressure gun of the high pressure washer is not completely released: hold the trigger of the water gun to release the pressure in the pump.

High pressure cleaning machine equipment in the long-term use of the process encountered more problems is insufficient pressure, safety valve leakage and the whole 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.
