光學超聲波清洗機工作時，超聲波會在介質中傳播，由于超聲波與介質的相互作用，使介質發(fā)生物理和或化學的變化，從而產生一系列力學、熱、電磁和化學的超聲效應。質量高的光學超聲波清洗機一般都會包括以下幾種效應：

When the optical ultrasonic cleaning machine is working, the ultrasonic wave will propagate in the medium. Due to the interaction between the ultrasonic wave and the medium, the physical and chemical changes of the medium will occur, resulting in a series of mechanical, thermal, electromagnetic and chemical ultrasonic effects. High quality optical ultrasonic cleaning machine generally includes the following effects:

一、機械效應

1、 Mechanical effect

光學超聲波清洗機的機械作用可促成液體的乳化、凝膠的液化和固體的分散。當超聲波流體介質中形成駐波時，懸浮在流體中的微小顆粒因受機械力的作用而凝聚在波節(jié)處，在空間形成周期性的堆積。超聲波在壓電材料和磁致伸縮材料中傳播時，由于超聲波的機械作用而引起感生電 機 化和感生磁化。

The mechanical action of the optical ultrasonic cleaner can promote the emulsification of the liquid, the liquefaction of the gel and the dispersion of the solid. When standing wave is formed in ultrasonic fluid medium, micro particles suspended in the fluid condense at the wave node due to mechanical force, forming periodic accumulation in space. When ultrasonic wave propagates in piezoelectric materials and magnetostrictive materials, induced electromotion and induced magnetization are caused by ultrasonic mechanical action.

二、空化作用

2、 Cavitation

光學超聲波清洗機的超聲波作用于液體時可產生大量小氣泡。一個原因是液體內局部出現拉應力而形成負壓，壓強的降低使原來溶于液體的氣體過飽和，而從液體逸出，成為小氣泡。另一原因是強大的拉應力把液體“撕開”成一空洞，稱為空化。因空化作用形成的小氣泡會隨周圍介質的振動而不斷運動、長大或突然破滅，破滅時周圍液體突然沖入氣泡而產生高溫、高壓，同時產生激波。

When ultrasonic wave of optical ultrasonic cleaning machine acts on liquid, a large number of small bubbles can be produced. One of the reasons is that the local tensile stress in the liquid forms negative pressure. The decrease of the pressure makes the gas dissolved in the liquid supersaturate, and then escape from the liquid and become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation. The small bubbles formed by cavitation will continuously move, grow or burst with the vibration of the surrounding medium. When the bubbles burst, the surrounding liquid suddenly rushes into the bubbles and produces high temperature, high pressure and shock wave.

三、化學效應

3、 Chemical effect

光學超聲波清洗機的超聲波的作用可促使發(fā)生或加速某些化學反應。例如純的蒸餾水經超聲處理后產生過氧化氫；溶有氮氣的水經超聲處理后產生亞硝酸；染料的水溶液經超聲處理后會變色或退色，這些現象的發(fā)生總與空化作用相伴隨。超聲波還可加速許多化學物質的水解、分解和聚合過程，超聲波對光化學和電化學過程也有明顯影響。

The ultrasonic effect of optical ultrasonic cleaning machine can promote or accelerate some chemical reactions. For example, pure distilled water produces hydrogen peroxide after ultrasonic treatment; water dissolved in nitrogen produces nitrite after ultrasonic treatment; aqueous solution of dye changes color or fade after ultrasonic treatment, which is always accompanied by cavitation. Ultrasound can also accelerate the hydrolysis, decomposition and polymerization of many chemicals, and also has obvious effects on photochemical and electrochemical processes.

以上就是光學超聲波清洗機的三種效應，其中主要就是利用超聲空化效應。暢銷全球的光學超聲波清洗機由超聲波電源發(fā)出的高頻振蕩信號，經換能器轉變?yōu)闄C械振動傳入到清洗介質中，以連續(xù)不斷的方式產生輻射狀直線傳播的超聲波束，強烈沖刷零件的表面，保括孔隙、夾縫等部位，達到清潔效果。

The above are the three effects of optical ultrasonic cleaning machine, which mainly uses ultrasonic cavitation effect. High frequency oscillation signal from ultrasonic power supply is transformed into mechanical vibration and transmitted into cleaning medium by transducer, which generates radiated straight-line ultrasonic beam in a continuous way, which strongly washes the surface of parts, covers the pores and cracks, and achieves the cleaning effect.
