Generally, the pressure of the Street Washer Vehicle is 5-8MPa, that is, 50-80kg pressure. Kg pressure is a unit of engineering mechanics, but the actual expression is not pressure but pressure. The standard unit is kgf/㎝ square, that is, the pressure produced by a 1kg weight object pressed on an area of 1 square centimeter. Strictly speaking, 1kgf/ CMS ² equals 0.098MPa, now the general kg pressure is calculated according to 0.1MPa. General pressure washers are used to wash the car, the pressure is generally not more than 7MPa, that is, 70 kilograms of pressure, the maximum pressure of the self-service car wash machine is 120 kilograms, when using can be adjusted according to the actual demand.

The working principle of the Street Washer Vehicle and the high pressure cleaning machine is similar. The high pressure piston pump is driven by the power device to produce high pressure water flow to wash away the dust and dirt on the surface of the object. However, if the high-pressure cleaning owner is used to wash the sanitation road and the garbage can, the pressure will be relatively high, generally in 15-28MPa, that is, 150-280 kg pressure.
