Pressure washer in China has different names, most people call it a high pressure water cleaning machines, high pressure water cleaning machines, high pressure water jet equipment.

    The pressure washer is the water as the working medium, usually power driven pump through the water to complete a suction exhaust process, the ordinary water into a high pressure low flow rates, water, and then transported to the high-pressure piping, so that a certain energy to reach the high-pressure Spray Nozzle. High-pressure Spray Nozzle aperture than the high-pressure pipeline diameter is much smaller, so the water in order to reach the high-pressure Spray Nozzle must be accelerated through a Spray Nozzle. , Spray Nozzle pressure and low velocity water into the low pressure and high velocity jet. Spray high pressure water jet cutting or positive impact of clean objects (artifacts) on the surface, known as jet operations. The high-pressure water jet is the energy shift and the most simple form. The high-pressure water jet impact force greater than the adhesion of dirt and surface dirt stripped, washed away, to a cleaning device for cleaning surfaces. Pressure washer to clean up dirt, because it is the use of high-pressure jet of water high pressure cleaner is also recognized worldwide as the most scientific, economical, environmentally friendly way to clean one.
