The types of cleaning machines include: trichloride machine, gas camera, hydraulic cleaning machine, cold water high-pressure cleaning machine, hot water high-pressure cleaning machine, electric driven cleaning machine, gasoline driven cleaning machine, electric heating high-pressure cleaning machine, diesel heating high-pressure cleaning machine, ultra-high pressure mobile cleaning machine, industrial stainless steel high-pressure cleaning machine, explosion-proof high-pressure cleaning machine, hydraulic cleaning machine, ultrasonic cleaning machine. 1. Hydraulic washer: It is used to flush and filter pollutants generated or intruded during manufacturing, assembly, use and maintenance of hydraulic system; It can also be used for regular maintenance and filtration of working oil to improve cleanliness and avoid or reduce failures caused by pollution, thus ensuring high performance, high reliability and long service life of hydraulic system equipment. The cleaning effect of the hydraulic cleaning device can reach NAS1638:2 level. 2. High pressure washer; High pressure washer is a machine that uses power device (motor, gasoline engine, diesel engine) to make high-pressure plunger pump produce high-pressure water to wash object surface. It can peel and wash away the dirt to clean the surface of objects. Because high-pressure water column is used to clean dirt, high-pressure cleaning is also recognized as one of the most scientific, economic and environmentally friendly cleaning methods in the world. It can be divided into: cold water type, hot water type, gasoline engine type according to on-site use and process requirements. In special occasions, there are explosion-proof type, special type for food industry, etc. 3. Ultrasonic cleaning machine: It is a kind of full ultrasonic cleaning that uses ultrasonic cavitation technology and the principle of ultrasonic transducer vibration emission to thoroughly clean dirt, oil dirt, sediment and other dirt attached to articles. The cleaning effect is obvious and intuitive, and it is a full ultrasonic cleaning that integrates washing, cleaning and sterilization. 4. Spray washer: It is an industrial cleaning equipment that uses water pressure to wash the surface of objects. It peels off and washes away the dirt on the surface of the workpiece to clean the surface of the object. This machine has many stations, full functions, reasonable structure, convenient operation, and good cleaning effect. It is of great significance for cleaning large quantities of workpieces, improving the working environment, and improving the quality of cleaning and drying. The cleaning machine is fully automatic with relay control. Except for manual loading and unloading of workpieces, all other processes are completed automatically.
