High-pressure cleaning machines have different names in my country. They can usually be called high-pressure water cleaning machines, high-pressure water flow cleaning machines, high-pressure water jet equipment, etc. In daily work and use, if we inadvertently make operational errors or fail to perform appropriate maintenance, it will cause a series of problems with the high-pressure cleaning machine. Pressure washer is a commonly used cleaning equipment, widely used in industrial, agricultural and household cleaning fields. However, due to long time use or improper operation, there will be some common faults in the pressure cleaning machine. Here are some common high-pressure cleaning machine failures and solutions. So, what are the causes of these failures? Let’s introduce this aspect below.
The first common fault:
When the power switch of the high-pressure cleaning machine is turned on, although the machine has high-voltage 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 inappropriately selected, the high-pressure frequency coordination is not adjusted properly, the cleaning fluid level in the cleaning tank is inappropriate, etc.
The second common fault:
The DC fuse DCFU of the high-pressure cleaning machine has blown. The cause of this failure is likely to be caused by a burnt rectifier bridge stack or power tube or a transducer failure.
The third common fault:
When the power switch of the high-pressure cleaner is turned on, although the indicator light is on, there is no high-pressure output. There are many factors causing this failure. They are: the fuse DCFU is blown; the transducer is faulty; the connecting plug between the transducer and the high-voltage power board is loose; the ultrasonic power generator is faulty.
The fourth common fault:
When the power switch of the high-pressure cleaner is turned on, the indicator light does not light up. The most likely cause of this failure is that the ACFU fuse is blown or the power switch is damaged and there is no power input. According to the phenomenon provided by the original poster, the preliminary diagnosis is that the high-voltage output protection action is caused. Please check whether the cleaning pipe is blocked. The specific reasons require further testing.
In addition, the high-pressure cleaning machine may also appear nozzle blockage, pressure instability and other failures. For these faults, they can be solved by cleaning the nozzle and adjusting the pressure valve.
In general, there may be various faults in the daily use of the high pressure cleaning machine, but as long as the timely discovery and take the correct solution, we can ensure the normal operation of the equipment, extend the service life of the equipment, and ensure the smooth progress of the cleaning work. I hope you can pay attention to the maintenance of equipment when using the high-pressure cleaning machine to avoid unnecessary failures.
