超声清洗系统重要的部分是换能器。现存两种换能器，一种是磁力换能器，由镍或镍合金制成；一种压电换能器，由锆钛酸铅或其他陶瓷制成。下面来看看超声波清洗机换能器和发生器的内容吧。

The transducer is an important part of ultrasonic cleaning system. There are two kinds of transducers, one is magnetic transducer, which is made of nickel or nickel alloy; A piezoelectric transducer is made of lead zirconate titanate or other ceramics. Let's take a look at the contents of the transducer and generator of the ultrasonic cleaning machine.

无论使用何种换能器，通常基本的因素为其产生的空化效应的强度。超声波和其它声波一样，是一系列的压力点，即一种压缩和膨胀交替的波。

No matter what kind of transducer is used, the basic factor is usually the intensity of the cavitation effect. Like other sound waves, ultrasonic waves are a series of pressure points, that is, waves with alternating compression and expansion.

如果声能足够强，液体在波的膨胀阶段被推开，由此产生气泡；而在波的压缩阶段，这些气泡就在液体中瞬间爆裂或内爆，产生一种非常有效的冲击力，特别适用於清洗。这个过程被称做空化作用。

If the sound energy is strong enough, the liquid is pushed away in the expansion phase of the wave, resulting in bubbles; In the compression phase of the wave, these bubbles burst or implode instantly in the liquid, producing a very effective impact force, which is especially suitable for cleaning. This process is called cavitation.

从理论上分析，爆裂的空化泡会产生超过10,000psi的压力和20,000°F（11,000°C）的高温，并在其爆裂的瞬间冲击波会迅速向外辐射。

Theoretically, the burst cavitation bubble will produce a pressure of more than 10000psi and a high temperature of 20000 ° f (11000 ° C), and the shock wave will rapidly radiate outward at the moment of its burst.

单个空化泡所释放的能量很小，但每秒钟内有几百万的空化泡同时爆裂，累计起来的效果将是非常强烈的，产生的强大的冲击力将工件表面的污物剥落，这就是所有超声清洗的特点。

The energy released by a single cavitation bubble is very small, but millions of cavitation bubbles burst at the same time every second, and the cumulative effect will be very strong. The powerful impact produced will peel off the dirt on the surface of the workpiece, which is the characteristic of all ultrasonic cleaning.

超声波清洗机生产厂家认为如果超声能量足够大，空化现象会在清洗液各处产生，所以超声波能够有效清洗微小的裂缝和孔。空化作用也促进了化学反应并加速了表面膜的溶解。

The manufacturer of ultrasonic cleaning machine believes that if the ultrasonic energy is large enough, cavitation will occur everywhere in the cleaning fluid, so ultrasonic can effectively clean tiny cracks and holes. Cavitation also promotes the chemical reaction and accelerates the dissolution of the surface facial mask.

然而只有在某区域的液体压力低於该气泡内气体压力时才会在该区域产生空化现象，故由换能器产生的超声波振幅足够大时才能满足这一条件。产生空化所需的小功率被称做空化临界点。

However, only when the liquid pressure in a certain area is lower than the gas pressure in the bubble will cavitation occur in this area, so this condition can be met when the ultrasonic amplitude generated by the transducer is large enough. The small power required to produce cavitation is called the cavitation critical point.

不同的液体存在不同的空化临界点，故超声波能量必须超过该临界点才能达到清洗效果。也就是说，只有能量超过临界点才能产生空化泡，以便进行超声清洗。

Different liquids have different cavitation critical points, so the ultrasonic energy must exceed this critical point to achieve the cleaning effect. In other words, cavitation bubbles can be generated only when the energy exceeds the critical point for ultrasonic cleaning.
