由浅至深了解超声波清洗（From shallow to deep understanding of ultrasonic cleaning）

由浅至深了解超声波清洗（From shallow to deep understanding of ultrasonic cleaning） From shallow to deep understanding of ultrasonic cleaning Release time: 2007-05-15 13:37:31 Ultrasonic cleaning principle: Ultrasonic cleaning machine is through ultrasonic generator will be higher than the 20KHz frequency of the shock signal power amplified by the ultrasonic transducer (shaking head) of the inverse piezoelectric effect is converted into high frequency mechanical vibration energy through the cleaning medium of sound radiation, the cleaning liquid molecular vibration and generate millions of tiny bubbles. Bubble formation and growth along the direction of propagation of ultrasound in negative pressure area, and in the area of positive pressure quickly closed and the instantaneous pressure generated thousands of atmospheric pressure and blasting, the formation of numerous micro high-pressure shock wave on the surface to be cleaned. This is the cavitation effect in ultrasonic cleaning. Ultrasonic cleaning machine is based on the cavitation effect of the basic working principle, therefore, ultrasonic cleaning are excellent ability to clean the workpiece with complex structure, and micro rough surface, slit, holes, corner, corner, element intensive features, he is the cleaning method There is nothing comparable to this. With the increase of ultrasonic frequency, the number of bubbles increases and the impact of blasting is weakened. Therefore, high frequency ultrasound is especially suitable for cleaning small particles of dirt without breaking the surface of the workpiece. Two, the expansion of cavitation bubble and burst (implosion) Bubbles are produced by applying high frequency (ultrasonic frequencies) and high intensity sound waves in liquids. Therefore, any ultrasonic cleaning system must have three basic components: a tank for cleaning liquid, a transducer for converting electrical energy into mechanical energy, and an ultrasonic generator for generating high frequency electric
