The principle of the cold water high-pressure cleaning machine is to use the power device to make the high-pressure plunger pump generate high-pressure water to wash the surface of the object. The impact force of the water is greater than the adhesion between the dirt and the surface of the object. The high-pressure water will peel off the dirt and wash it away, thereby achieving the purpose of cleaning the surface of the object. High-pressure cleaning machines are used to wash various motor vehicles, mechanical equipment, building exterior walls, floors, baths, swimming pools, etc. At present, high-pressure cleaning machines have a broad market. The demand in the Guoji market is around ten million units every year, and the market demand is constantly increasing.

In the domestic market, the current high-pressure cleaning machine market is still in its early stages of development, and the use of cold water high-pressure cleaning machines is not widespread. However, with the improvement of people's living standards, especially the gradual popularization of automobiles and the gradual improvement of people's living environment, as well as the increase in our contacts with people from developed countries, the influence of foreign lifestyles on us is also increasing. The domestic high-pressure cleaning machine market is also rapidly expanding, and market demand is increasing rapidly.

As the number of cars in our country continues to increase, the car beauty industry is developing rapidly. Car cleaning, as the main item of car beauty, puts forward increasingly higher requirements for cleaning equipment. A high-pressure cold water cleaning machine can be used to clean the exterior of the vehicle, while high-temperature and high-pressure cleaning machines are more effective in cleaning parts such as engines with more oil stains. High-pressure cleaners combined with vacuum and water suction machines have become one of the standard features in the automotive beauty industry. In the past, imported high-pressure cleaning machines were mainly used. However, the structure of this cleaning equipment is complex, maintenance is inconvenient, and the accessories are expensive. Nowadays, a number of professional high-pressure cleaning equipment manufacturers have emerged in China. Not only are the prices lower than imported machines, but the spare parts are abundant and timely supplied, which has effectively improved the after-sales problems of high-pressure cleaning machines. Of course, in order to reduce the failure rate of equipment and extend its service life, it must be used correctly and maintained.
