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.

超聲波清洗技術在電子、機電、醫藥行業的應用是早的，也是為普及的。電子產品的零件、配件、電路板、芯片等等物件體積小、形狀不規則，傳統的清洗方式很難去污，但超聲清洗技術很容易就將這些物件清洗干凈，且不會損壞這些小部件。機電行業中的機械部件體積大，質量重，油污重，傳統的清洗方式需要大量的人力物力和水資源，容易造成污染和浪費，但超聲清洗技術易于實現自動化，環保無污染，非常的經濟實用。醫藥行業的物品種類繁多，藥品易碎且不易清洗瓶內壁，傳統的清洗方式清洗效果不盡人意，且可能會有二次污染，但超聲清洗方式可以實現清洗、吹干、旋轉等多個環節的自動化管理，非常方便和衛生。

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.

超聲波清洗技術在輕紡行業和表面處理中也有較為廣泛的應用。人們日常生活當中常見的、貴重的、不宜使用傳統的清洗方式的零部件，如鐘表手表零配件、眼鏡零配件、首飾玉器等等形狀不規則的物件，超聲波清洗效果非常好，而且超聲波清洗機體積不大，價錢實惠，可以清洗到盲孔、微孔部位的污塘，具有很大的優勢和發展前景。

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.

近年來，超聲波清洗也應用在鐵路和軍事行業。不易拆洗的發動機和散熱器、污拒嚴重的鐵路軌道、軍事裝備中的機電設備、演習裝備、復雜兵器等等污據較多、人工難以擦洗干凈的大型設備，超聲波清洗可以方便快捷無損耗的清洗干凈另外，超聲波清洗在電鍍、噴涂前工藝、除油污、磷化處理等方面也有應用。這些方面的應用時需要使用特殊的清洗溶液，操作起來也很方便，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.
