[0002] The main principle of high-pressure water cleaning machine is that high-pressure water is generated by a high-pressure pump, and the high-pressure water is converted into high-speed water jets through the nozzle to strike, erode and peel off the cleaning object to achieve the purpose of cleaning and descaling. It has the significant advantages of high cleaning efficiency, good effect, no pollution, no corrosion to pipes, low labor intensity of workers, saving raw materials, beneficial to environmental protection, and strong versatility.

[0003] The current high-pressure water cleaning machine has the following shortcomings: on the one hand, due to the presence of bubbles in the low-pressure liquid supply pipeline supplying the plunger pump, it will cause impact on the plunger pump; on the other hand, the inlet and outlet liquid pressures of the filter are unclear, and the actual service life of the filter element and the real-time liquid supply pressure cannot be grasped.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-pressure water cleaning machine is proposed. Utility Model Content

[0007] Furthermore, the filter has a built-in ten-micron filter element, and the filter is installed in an inverted manner.

[0008] Furthermore, an exhaust valve is connected to the top of the filter, and a drainage pipeline is connected to the bottom of the filter.

[0009] Furthermore, a plunger pump is arranged on the back side of the machine body, and the plunger pump is connected to the output end of the motor.

[0010] Furthermore, when the liquid inlet valve is normally open, pure water is supplied to the plunger pump through the filter, and the provision of the exhaust valve can reduce bubbles in the discharge pipeline to protect the plunger pump.

[0011] Furthermore, a safety valve is connected to one side of the plunger pump, and a pneumatic ball valve is connected to the other side of the plunger pump.

[0012] Furthermore, the motor drives the plunger pump to convert low-pressure water into high-pressure water and supplies it through the pneumatic ball valve, and when the pressure threshold is exceeded, the safety valve opens to protect the plunger pump and its high-pressure pipeline.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, the high-pressure water cleaning machine of the present application is divided into a low-pressure liquid supply pipeline and a high-pressure liquid supply pipeline. When the liquid inlet valve is normally open, pure water is supplied to the plunger pump through the filter. Pressure gauges are installed before and after the filter. While monitoring the liquid supply pressure, it is also convenient to check the use of the filter element.

[0015] 2. When the utility model is in use, the low-pressure liquid supply pipeline uses a liquid inlet valve made of PFA material to supply liquid to the high-pressure liquid supply pipeline through a ten-micron filter. At the same time, the filter is inverted, and the exhaust valve can reduce the generation of bubbles at the liquid supply end. In addition, the motor drives the plunger pump to convert low-pressure water into high-pressure water and connects to the pneumatic ball valve through a pipeline to control the switch of the high-pressure water.
