The realization of the cleaning effect of ultrasonic cleaning machine mainly depends on "cavitation effect". Therefore, the effect of "cavitation" can affect the performance of the machine; The high performance of the machine determines the cleaning effect. In order to achieve the purpose of cleaning, the root should be traced back to its source. Therefore, the influence factors of cavitation effect cannot be ignored.

（1）频率的选择

(1) Frequency selection

清洗液中即使通入超声波，并不一定能够产生空化小泡；即使产生了空化小泡，也不一定能够完全爆破；即使爆破了，超声清洗机清洗也不一定能够达到良好的剥脱污物的效果。

Even if ultrasonic wave is introduced into the cleaning solution, cavitation bubbles may not be generated; Even if cavitation bubbles are produced, they may not be able to completely explode; Even after blasting, ultrasonic cleaning machine may not achieve a good effect of stripping dirt.

每一种液体都有自己的&濒诲辩耻辞;空化阈值&谤诲辩耻辞;。是超声波振动产生的负压超过了液体本身的静压力，才能将其撕开，形成真空泡。超声空化阈值与超声波频率有密切的关系

Each liquid has its own "cavitation threshold". It is only when the negative pressure generated by ultrasonic vibration exceeds the static pressure of the liquid itself that it can be torn to form a vacuum bubble. There is a close relationship between ultrasonic cavitation threshold and ultrasonic frequency

频率越高，空化阈值越高。因为超声波的频率越高，它的能量会很低，没有那么大的力气撕开液体形成空泡。所以高频率的超声波不容易在液体中形成空化泡，要产生空化，需要加大声功率。

The higher the frequency, the higher the cavitation threshold. Because the higher the frequency of the ultrasonic wave, the lower its energy will be, and there is not so much force to tear the liquid to form bubbles. Therefore, high-frequency ultrasound is not easy to form cavitation bubbles in the liquid. To produce cavitation, it is necessary to increase the power.

反过来，频率越低，产生空化越容易。而且，频率低了，撕开和挤压两者之间的时间间隔多了许多，生成的小泡有足够的时间来完成生长，由小变大，那么它爆破时产生的冲击力更大了，更有利于清洗。

Conversely, the lower the frequency, the easier it is to produce cavitation. In addition, the lower the frequency, the longer the time interval between tearing and squeezing, and the generated bubbles have enough time to complete the growth, from small to large, so the impact force generated when it explodes is greater, which is more conducive to cleaning.

高频与低频，像马跑得很快，但力气小，拉不了太多的重物；而牛跑得很慢，但力气很大，拉着一大车牛粪都能够闲庭散步，其实各有用处。

High frequency and low frequency are like horses running fast, but with little strength, they can't pull too much weight; The cow runs very slowly, but has great strength. It can walk in a leisurely way with a cart of cow dung. In fact, each has its own use.

我们可以根据清洗对象将超声波频率分为3个频段：低频（20碍贬锄&尘诲补蝉丑;50碍贬锄），高频（50碍贬锄&尘诲补蝉丑;200碍贬锄），超高频（700碍贬锄&尘诲补蝉丑;1惭贬锄以上）。在相同的功率下，40碍贬锄频率的超声波比100碍贬锄的超声波产生更多的空化泡，穿透能力更强，但容易造成器械表面的腐蚀和损坏，噪声也更大。

We can divide the ultrasonic frequency into three frequency bands according to the cleaning object: low frequency (20KHz-50KHz), high frequency (50KHz-200KHz), and ultra-high frequency (700KHz-1MHz or above). At the same power, 40KHz ultrasonic wave produces more cavitation bubbles than 100KHz ultrasonic wave, with stronger penetration ability, but it is easy to cause corrosion and damage to the surface of the instrument, and the noise is also greater.

因此，高频超声波适用于清洗精密精细的器械，低频超声波适用于清洗粗大坚固的器械。

Therefore, high-frequency ultrasound is suitable for cleaning precision and fine instruments, while low-frequency ultrasound is suitable for cleaning thick and solid instruments.
