1、 Ultrasonic degassing

超聲波脫氣是用真空泵循環(huán)的方式將溶解在清洗液的氣體脫離出來，使得清洗液能夠更好的成為傳遞超聲波震蕩的介質(zhì)。

Ultrasonic degassing is the process of using a vacuum pump to circulate the gas dissolved in the cleaning solution, allowing the cleaning solution to become a better medium for transmitting ultrasonic vibrations.

超聲波震蕩能量輻射會受到清洗液中的空氣濃度較大的影響，若清洗液中殘存的氣體較多，則會阻礙超聲波的傳播，從而降低清洗力。因此，可利用脫氣裝置來排出清洗液中的氣體，的提高清洗效果。

The energy radiation of ultrasonic vibration is greatly affected by the air concentration in the cleaning solution. If there is a large amount of residual gas in the cleaning solution, it will hinder the propagation of ultrasonic waves and reduce the cleaning force. Therefore, a degassing device can be used to exhaust the gas in the cleaning solution, thereby improving the cleaning effect.

將清洗液中氣體脫氣后，工件在空氣殘存極少的環(huán)境下清洗，可以有效地在清洗過程中產(chǎn)生氧化的問題。

After degassing the gas in the cleaning solution, cleaning the workpiece in an environment with minimal residual air can effectively solve the problem of oxidation during the cleaning process.

有利于盲孔零件內(nèi)空氣排出及清洗液的滲入，收到更佳清洗效果,清洗液經(jīng)脫氣處理，超聲波得到更佳發(fā)揮，在清洗液內(nèi)形成真空效應(yīng)，清洗效果更徹底，潔凈度更高。

It is conducive to the discharge of air and the infiltration of cleaning fluid in blind hole parts, achieving better cleaning effect. After degassing treatment, the cleaning fluid is subjected to ultrasonic waves for better performance, forming a vacuum effect in the cleaning fluid, resulting in a more thorough cleaning effect and higher cleanliness.

二、超聲波掃頻

2、 Ultrasonic scanning frequency

超聲波掃頻是在清洗過程中超聲波頻率在合理的范圍內(nèi)往復(fù)掃動，其作用是可以改善超聲波清洗槽內(nèi)超聲場的結(jié)構(gòu)。

Ultrasonic frequency scanning refers to the reciprocating scanning of ultrasonic frequency within a reasonable range during the cleaning process, which can improve the structure of the ultrasonic field in the ultrasonic cleaning tank.

超聲波清洗機工作在一個固定頻率有較大的局限性，由于某些參數(shù)，如水溫、清洗量等的變化，容易產(chǎn)生諧振頻率的漂移，從而造成聲功率的變化，影響到清洗效果。

The Ultrasonic cleaning has great limitations when it works at a fixed frequency. Due to the change of some parameters, such as water temperature, cleaning volume, etc., it is easy to produce the drift of resonance frequency, which will cause the change of sound power and affect the cleaning effect.

所以超聲波掃頻功能能適應(yīng)更大范圍的清洗寬度要求。

So the ultrasonic scanning function can adapt to a larger range of cleaning width requirements.

三、超聲波變頻清洗

3、 Ultrasonic frequency conversion cleaning

超聲波頻率不一樣，進行空化的效應(yīng)的結(jié)果也不一樣，頻率越高，產(chǎn)生的汽泡越小，穿透性越強，但是相應(yīng)的力度越小。頻率越低，產(chǎn)生的氣泡越大，穿透性越弱，但是清洗表面的力度越強。

The frequency of ultrasound is different, and the results of cavitation effect are also different. The higher the frequency, the smaller the generated bubbles, the stronger the penetration, but the corresponding force is smaller. The lower the frequency, the larger the bubbles generated, the weaker the penetration, but the stronger the cleaning force on the surface.
