Ultrasonic cleaning is a major branch of power ultrasound and is also widely used in practical applications. Ultrasonic cleaning has many obvious advantages. Compared with traditional cleaning methods, there is less residue left after cleaning. Ultrasonic cleaning is fast, saves water resources, is environmentally friendly and pollution-free, has little damage to objects, has good cleaning effects, high cleaning quality, and is easy to achieve automation. This energy-saving and environmentally friendly ultrasonic cleaning technology has been applied in electronics, electromechanical, light industry and textile, aerospace, military railways, precision instruments, etc Medical devices and other fields of national construction are widely used and highly praised. China has studied this technology earlier, such as the mechanism of ultrasonic cleaning machines, the development of ultrasonic cleaning machines, equipment production, and cleaning processes. Now, this technology is relatively mature. With the in-depth research of scientific researchers on ultrasonic cavitation phenomena, piezoelectric transducers, and other fields, ultrasonic cleaning technology has rapidly developed.

超声波清洗技术在电子、机电、医药行业的应用是早的，也是为普及的。电子产品的零件、配件、电路板、芯片等等物件体积小、形状不规则，传统的清洗方式很难去污，但超声清洗技术很容易将这些物件清洗干净，且不会损坏这些小部件。机电行业中的机械部件体积大，质量重，油污重，传统的清洗方式需要大量的人力物力和水资源，容易造成污染和浪费，但超声清洗技术易于实现自动化，无污染，非常的经济实用。医药行业的物品种类繁多，药品易碎且不易清洗瓶内壁，传统的清洗方式清洗效果不尽人意，且可能会有二次污染，但超声清洗方式可以实现清洗、吹干、旋转等多个环节的自动化管理，非常方便和卫生。

The application of ultrasonic cleaning technology in the electronics, electromechanical, and pharmaceutical industries is early and widespread. The components, accessories, circuit boards, chips, and other objects of electronic products are small and irregularly shaped, making it difficult to remove dirt using traditional cleaning methods. However, ultrasonic cleaning technology can easily clean these objects without damaging these small components. The mechanical components in the electromechanical industry are large in volume, heavy in quality, and heavily contaminated with oil. Traditional cleaning methods require a large amount of manpower, material resources, and water resources, which can easily cause pollution and waste. However, ultrasonic cleaning technology is easy to achieve automation, environmentally friendly, and pollution-free, making it very economical and practical. The pharmaceutical industry has a wide variety of items, with drugs being fragile and difficult to clean the inner walls of bottles. Traditional cleaning methods have unsatisfactory cleaning effects and may cause secondary pollution. However, ultrasonic cleaning can achieve automated management of multiple processes such as cleaning, drying, and rotation, which is very convenient and hygienic.

超声波清洗技术在轻纺行业和表面处理中也有较为广泛的应用。人们日常生活当中常见的、贵重的、不宜使用传统的清洗方式的零部件，如钟表手表零配件、眼镜零配件、首饰玉器等等形状不规则的物件，超声波清洗效果非常好，而且超声波清洗机体积不大，价钱实惠，可以清洗到盲孔、微孔部位的污塘，具有很大的优势和发展前景。

Ultrasonic cleaning technology is also widely used in the light textile industry and surface treatment. Common, valuable, and unsuitable components for traditional cleaning methods in people's daily lives, such as clock and watch parts, glasses parts, jewelry, jade, and other irregularly shaped objects, have excellent ultrasonic cleaning effects. Moreover, ultrasonic cleaning machines are small in size and affordable in price, and can clean dirty pools in blind holes and micropores, which has great advantages and development prospects.

近年来，超声波清洗也应用在铁路和军事行业。不易拆洗的发动机和散热器、污拒严重的铁路轨道、军事装备中的机电设备、演习装备、复杂兵器等等污据较多、人工难以擦洗干净的大型设备，超声波清洗可以方便快捷无损耗的清洗干净另外，超声波清洗在电镀、喷涂前工艺、除油污、磷化处理等方面也有应用。这些方面的应用时需要使用特殊的清洗溶液，操作起来也很方便，效果很好。

In recent years, ultrasonic cleaning has also been applied in the railway and military industries. Large equipment with high levels of pollution, such as engines and radiators that are difficult to disassemble and clean, railway tracks with severe pollution, electromechanical equipment in military equipment, exercise equipment, complex weapons, etc., and difficult to clean manually, can be cleaned easily, quickly, and without loss. In addition, ultrasonic cleaning is also applied in electroplating, pre spraying processes, oil removal, and phosphating treatment. These applications require the use of special cleaning solutions, which are also very convenient to operate and have good results.
