1、 Ultrasonic degassing

超声波脱气是用真空泵循环的方式将溶解在清洗液的气体脱离出来，使得清洗液能够更好的成为传递超声波震荡的介质。

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.

超声波震荡能量辐射会受到清洗液中的空气浓度较大的影响，若清洗液中残存的气体较多，则会阻碍超声波的传播，从而降低清洗力。因此，可利用脱气装置来排出清洗液中的气体，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.

将清洗液中气体脱气后，工件在空气残存极少的环境下清洗，可以有效地在清洗过程中产生氧化的问题。

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.

有利于盲孔零件内空气排出及清洗液的渗入，收到更佳清洗效果,清洗液经脱气处理，超声波得到更佳发挥，在清洗液内形成真空效应，清洗效果更彻底，洁净度更高。

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、超声波扫频

2、 Ultrasonic scanning frequency

超声波扫频是在清洗过程中超声波频率在合理的范围内往复扫动，其作用是可以改善超声波清洗槽内超声场的结构。

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.

超声波清洗机工作在一个固定频率有较大的局限性，由于某些参数，如水温、清洗量等的变化，容易产生谐振频率的漂移，从而造成声功率的变化，影响到清洗效果。

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.

所以超声波扫频功能能适应更大范围的清洗宽度要求。

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

三、超声波变频清洗

3、 Ultrasonic frequency conversion cleaning

超声波频率不一样，进行空化的效应的结果也不一样，频率越高，产生的汽泡越小，穿透性越强，但是相应的力度越小。频率越低，产生的气泡越大，穿透性越弱，但是清洗表面的力度越强。

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.
