1、 Ultrasonic degassing

超聲（shēng）波脫氣是（shì）用真空（kōng）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（chāo）聲（shēng）波震蕩的介質。

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（shòu）到清洗（xǐ）液（yè）中（zhōng）的空氣濃度較大的影響，若清（qīng）洗液中殘存的氣體較多，則（zé）會阻礙超聲波（bō）的傳播，從而降低清洗力。因此，可利用脫氣裝置（zhì）來排出清洗液中（zhōng）的氣體，的提高（gāo）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後，工件在空氣殘存極少的環境下清洗（xǐ），可（kě）以有效地解決在清洗過程中產生氧化的問題。

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（yǒu）利於盲孔零（líng）件內空氣（qì）排出（chū）及（jí）清洗液（yè）的滲入，收到更佳清洗效（xiào）果,清洗液經脫氣處理，超聲波得到更佳發揮，在清洗液內形成真空效應，清洗效果更徹底，潔淨度更（gèng）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（sǎo）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範圍內往複掃動，其作用是可以（yǐ）改善超聲波清洗槽內超聲場的結構。

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（dìng）頻率有較大的局限性，由於某些參（cān）數，如水溫、清洗量等的變化，容易產生諧振頻（pín）率（lǜ）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更大範圍的清洗寬度要（yào）求。

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

三、超聲（shēng）波變（biàn）頻清洗

3、 Ultrasonic frequency conversion cleaning

超聲波頻率不一（yī）樣，進行空化的效應的結果也不一樣，頻率越高，產生的汽（qì）泡越小，穿透性越強，但是相應的力度越小。頻率越低，產生的氣泡越大，穿透性越（yuè）弱，但是清洗表麵的力度越強。

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.
