What is the pressure of a general high-pressure cleaning car?

The pressure of high-pressure cleaning machine is generally not more than 7MPa, that is, 70 kg force. Usually, car washing machines have an adjustable pressure range. For example, the maximum pressure of our self-service car washer is 120 kg, which can be adjusted to the appropriate pressure as needed. High-pressure cleaning machine is a machine that makes high-pressure piston pump produce high-pressure water through power device to clean the surface of objects. It can peel off dirt and wash it off, thus achieving the purpose of cleaning the surface of objects. Unless it is a stubborn oil stain, you need to add a little detergent, otherwise the foam generated by strong water pressure is enough to take away the general dirt. Principle: The impact force of water is greater than the adhesion between dirt and the surface of the object, and high-pressure water peels off the dirt and washes it away, thus realizing the cleaning device for cleaning the surface of the object. Because the high-pressure water column is used to clean dirt, unless it is stubborn oil stains, it needs to add a little detergent, otherwise the foam generated by strong water pressure is enough to take away ordinary dirt.
