High-pressure water gun is a high-pressure washer, a common name for high-pressure water jet cleaning machine, which is a machine that flushes the surface of an object by making a high-pressure plunger pump generate high-pressure water through a power unit. It can peel off dirt, wash it away, and achieve the purpose of cleaning the surface of the object.

1. Ultrasonic cleaning is a way to install ultrasonic vibrators in the cleaning tank to generate ultrasonic energy (shock waves of thousands of atmospheres), and all the washed objects will be cleaned.

2. Spray cleaning Install a spray pipe in the cleaning tank, and spray the cleaning liquid onto the cleaned object in the gas phase, and the pressure is less than 2kg/cm2.

3. Vacuum cleaning produces negative pressure in the cleaning tank, and due to decompression, the detergent can better penetrate between the gaps of the washed object. If it works with ultrasound, the cleaning effect will be greatly enhanced.

4. Jet cleaning sprays the cleaning liquid in the liquid phase from the side of the tank, and relies on the stirring force of the cleaning liquid (physical action to promote cleaning. The washing capacity is stronger than impregnation cleaning.

5. Brushing and cleaning in the cleaning chamber to install brushes, workpieces have special supports or fixtures. While the cleaning agent is impregnated or wetted, it is mainly cleaned by the mechanical friction force between the brush and the workpiece, as a primary cleaning, and the effect is direct.

6. Spray cleaning Install a spray pipe in the washing tank, and attach the washing spray to the cleaned object in the gas phase.

7. Rotating cylinder cleaning Install a rotating device in the tank, and rotate the cylinder and stir the cleaned object at the same time. It is mostly used in combination with jet and ultrasonic washing.
