The high-pressure cleaning vehicle is also called the pipe dredging vehicle, which uses the strong pressure generated by the high-pressure water flow to open the blocked pipe. The main components are tanks, high-pressure pumps, hydraulic systems, etc. The high-pressure cleaning truck is mainly used to clean the sediments of urban sewers, pipelines, and dredge the dead-angle mud ditch. It can also be used to clean industrial drainage pipes, walls, etc., and clean the ground of roads and squares. The high-pressure cleaning vehicle can also be equipped with sprinklers, green sprinklers, front flush, rear sprinkler, side spray, green sprinkler, spray, dust pressure, high-pressure washing of the road surface, etc., and can be used for fire fighting in emergency. The principle of the high-pressure cleaning truck is to turn the curved steel wire into the clogged sewer pipe by rotating, and bring out the clogged cloth, hair and the like. There is also a tool called Yipaotong, which is a pneumatic dredging tool that uses the principle of high pressure to flush out blocked sewer pipes. The skin kick commonly used in daily life uses this principle to kick open blocked pipes.
