High Pressure Washer (Four Common Faults)

High pressure cleaners use water as the working medium. Usually, the power-driven pump completes a suction and discharge process for water, converts ordinary water into high-pressure, low-flow water, and then transports it to the high-pressure pipeline to make it have a certain energy. Reach the high pressure nozzle. The aperture of the high pressure nozzle is much smaller than the diameter of the high pressure line, so the water reaching the high pressure nozzle must be accelerated in order to pass through the nozzle. In this way, the nozzle can turn the high pressure, low flow rate water into a low pressure, high flow rate jet. When the impact force of the high-pressure water jet is greater than the adhesion between the dirt and the surface of the object, the dirt will be peeled off, washed away, and a cleaning device for cleaning the surface of the object is achieved. Because high pressure cleaners use high-pressure water column to clean the dirt, the high pressure cleaner is also one of the world's most recognized scientific, economic, and environmentally friendly cleaning methods.

We may encounter some common failures during the use of high pressure cleaners. So what are the causes of these failures?

The first kind of common fault: After turning on the power switch of the high pressure cleaner, although the machine has high pressure output, the cleaning effect is not very good. The reasons for this phenomenon are likely to be: the liquid temperature in the cleaning tank is too high, the cleaning fluid is not properly used, the high-frequency frequency coordination is not adjusted properly, and the cleaning liquid level in the cleaning tank is not suitable.

The second common fault: high pressure cleaner DC fuse DCFU fuse failure. The cause of this failure is likely to be caused by the burning of a rectifier bridge or power tube or due to a transducer failure.

The third common fault: When the high pressure cleaner power switch is turned on, the indication is that although the light is on, the high pressure is not output. There are many factors that cause this kind of failure, they are: the fuse DCFU is blown; the transducer fails; the connection plug of the transducer and the high-voltage power board appears loose; and the ultrasonic power generator fails.

The fourth common fault: when the high pressure cleaner power switch is turned on, the indicator light is off. The cause of this failure is likely to be a blown ACFU fuse or a damaged power switch, caused by no power input.
