超聲波清洗機換能器和發生器的認識

作者：admin來源：http://m.nianyankeji.cn/時間：2022-07-31

超聲清洗系統重要的部分是換能器。現存兩種換能器，一種是磁力換能器，由鎳或鎳合金制成；一種壓電換能器，由鋯鈦酸鉛或其他陶瓷制成。下面來看看超聲波清洗機換能器和發生器的內容吧。

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.

無論使用何種換能器，通常基本的因素為其產生的空化效應的強度。超聲波和其它聲波一樣，是一系列的壓力點，即一種壓縮和膨脹交替的波。

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.

如果聲能足夠強，液體在波的膨脹階段被推開，由此產生氣泡；而在波的壓縮階段，這些氣泡就在液體中瞬間爆裂或內爆，產生一種非常有效的沖擊力，特別適用於清洗。這個過程被稱做空化作用。

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.

從理論上分析，爆裂的空化泡會產生超過10,000psi的壓力和20,000°F（11,000°C）的高溫，并在其爆裂的瞬間沖擊波會迅速向外輻射。

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.

單個空化泡所釋放的能量很小，但每秒鐘內有幾百萬的空化泡同時爆裂，累計起來的效果將是非常強烈的，產生的強大的沖擊力將工件表面的污物剝落，這就是所有超聲清洗的特點。

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.

超聲波清洗機生產廠家認為如果超聲能量足夠大，空化現象會在清洗液各處產生，所以超聲波能夠有效清洗微小的裂縫和孔。空化作用也促進了化學反應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.

然而只有在某區域的液體壓力低於該氣泡內氣體壓力時才會在該區域產生空化現象，故由換能器產生的超聲波振幅足夠大時才能滿足這一條件。產生空化所需的小功率被稱做空化臨界點。

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.

不同的液體存在不同的空化臨界點，故超聲波能量必須超過該臨界點才能達到清洗效果。也就是說，只有能量超過臨界點才能產生空化泡，以便進行超聲清洗。

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.
