Cleaning machines are used to flush and filter contaminants generated or introduced into hydraulic systems during manufacturing, assembly, use, and maintenance. They can also be used for the periodic maintenance and filtration of working fluids, improving cleanliness, avoiding or reducing malfunctions caused by contamination, thereby ensuring the high performance, high reliability, and long lifespan of hydraulic system equipment.
Cleaning machines are complete sets of equipment integrating key technologies such as pumps, valves, high-pressure water jets, mechanical structures, conveying, and automation, as well as auxiliary technologies such as sealing, ventilation, heat exchange, cleaning fluid filtration, oil removal, and chip removal.
Cleaning machines are a typical type of modern equipment in the world today, characterized by advanced technology, prominent features, wide application range, and rapid development. Research and development of cleaning machine technologies began earlier abroad, and research on cleaning processes, methods, media, conditions, and objects has matured significantly. Coupled with existing automated equipment technology, the development of cleaning machine products has accelerated, progressing through several eras including spray cleaning, immersion cleaning, ultrasonic cleaning, evaporative degreasing, and laser cleaning. Some foreign cleaning machine companies have incorporated modular design into their product development, ensuring reasonable product compatibility and reliable quality while reducing costs and accelerating development. High-pressure cleaning, achieved through in-depth research into spray systems, is a key technology in the cleaning machine field. Currently, some high-quality foreign cleaning machines achieve cleaning pressures of up to 32 MPa, far exceeding domestic levels. Flexible cleaning machines based on servo motor control and water temperature and pressure control technology enable flexible cleaning of components with different structures. Ultrasonic cleaning machines based on ultrasonic radiation technology improve cleaning efficiency without damaging components, ensuring cleanliness, and achieving single-piece cleaning speeds of tens of seconds.
