超聲波清洗機(jī)電路具有自動(dòng)掃頻功能，脈沖電路，頻率更精準(zhǔn)、運(yùn)行更穩(wěn)定、脫氣效率更高，噪音更低。

　　The ultrasonic cleaning machine circuit has an automatic frequency scanning function, an efficient pulse circuit, more accurate frequency, more stable operation, higher degassing efficiency, and lower noise.

　　超聲波清洗機(jī)預(yù)處理

　　Ultrasonic cleaning machine pretreatment

　　清洗之前宜用竹刀先將零部件表面的污垢（如防塵罩外表面會(huì)有很多塵土、氣缸體類的零件在其外殼曲線變化處會(huì)積留很多厚且易除的油泥）簡單清潔一下，以便延長清洗液使用壽命。

　　Before cleaning, it is advisable to use a bamboo knife to clean the dirt on the surface of the components (such as a lot of dust on the outer surface of the dust cover, and a lot of thick and easily removable oil sludge will accumulate at the curve changes of the cylinder body), in order to extend the service life of the cleaning solution.

　　超聲波能夠進(jìn)行精密清洗，但其對(duì)泥類的污物處理能力較弱，故預(yù)處理中，應(yīng)盡量將黃泥或稀泥類的污物去除。

　　Ultrasound can perform precision cleaning, but its ability to treat mud like dirt is weak. Therefore, in pre-treatment, yellow mud or thin mud like dirt should be removed as much as possible.

　　工作原理

　　working principle

　　通過換能器，將功率超聲頻源的聲能轉(zhuǎn)換成機(jī)械振動(dòng)，通過清洗槽壁將超聲波輻射到槽子中的清洗液。由于受到超聲波的輻射，槽內(nèi)液體中的微氣泡能夠在聲波的作用下快速變大破裂，破裂時(shí)產(chǎn)生的高強(qiáng)度剪切力作用于各類樣品上，從而達(dá)到清洗、提取、乳化、加速溶解、粉碎、分散等作用。

　　By using a transducer, the sound energy of the power ultrasonic frequency source is converted into mechanical vibration, and the ultrasonic waves are radiated into the cleaning solution in the tank through the cleaning tank wall. Due to the radiation of ultrasound, microbubbles in the liquid in the tank can quickly grow and rupture under the action of sound waves. The high-strength shear force generated during rupture acts on various samples, achieving cleaning, extraction, emulsification, accelerated dissolution, crushing, dispersion, and other functions.

　　超聲波清洗機(jī)功率如何選擇？

　　How to choose the power of an ultrasonic cleaning machine?

　　超聲清洗效果不一定與（功率×清洗時(shí)間）成正比，有時(shí)用小功率，花費(fèi)很長時(shí)間也沒有污垢。而如果功率達(dá)到一定數(shù)值，有時(shí)很快便將污垢去除。若選擇功率太大，空化強(qiáng)度將大大增加，清洗效果是提高了，但這時(shí)使較精密的零件也產(chǎn)生蝕點(diǎn)，得不償失，而且清洗缸底部振動(dòng)板處空化嚴(yán)重，水點(diǎn)腐蝕也增大，在采用三氯乙烯等有機(jī)溶劑時(shí)，基本上沒有問題，但采用水或水溶性清洗液時(shí)，易于受到水點(diǎn)腐蝕，如果振動(dòng)板表面已受到傷痕，強(qiáng)功率下水底產(chǎn)生空化腐蝕更嚴(yán)重，因此要按實(shí)際使用情況選擇超聲功率。

　　The effect of ultrasonic cleaning may not be directly proportional to (power x cleaning time), and sometimes using low power may take a long time without removing dirt. If the power reaches a certain value, sometimes the dirt is quickly removed. If the selected power is too high, the cavitation intensity will greatly increase, and the cleaning effect will be improved. However, at this time, more precise parts will also produce corrosion points, which is not worth the loss. Moreover, the vibration plate at the bottom of the cleaning cylinder will have severe cavitation and increased water point corrosion. When using organic solvents such as trichloroethylene, there is basically no problem. However, when using water or water-soluble cleaning liquids, they are prone to water point corrosion. If the surface of the vibration plate has been damaged, the cavitation corrosion at the bottom of the water will be more severe under high power. Therefore, ultrasonic power should be selected according to actual usage conditions.
