As we all know, the sound people hear is a sound wave signal with a frequency of 20Hz~20000Hz, and the sound wave higher than 20000Hz is called ultrasonic wave. When the signal acts on the liquid, it will produce a certain negative pressure on the liquid, so that many tiny bubbles are formed in the liquid, and when a strong acoustic signal acts on the liquid, it will produce a certain positive pressure on the liquid, so, The tiny air bubbles that form in the liquid are crushed. Research has proved that when ultrasonic waves act on the liquid, the rupture of each bubble in the liquid will generate a shock wave with the greatest energy, which is equivalent to the instantaneous high temperature and thousands of atmospheres. This phenomenon is called "cavitation". "Effect", ultrasonic cleaning is to use the shock wave generated by the bubble burst in the liquid to achieve the effect of cleaning and scouring the inner and outer surfaces of the workpiece.

Other applications of ultrasonic cleaners

In addition to cleaning, ultrasonic cleaning machines can also be widely used in degassing, defoaming, emulsification, mixing, replacement, extraction, powder crushing and cell crushing. Among them, liquid phase degassing has become one of the main applications of ultrasonic cleaners in addition to cleaning, and has also become one of the necessary tools for liquid phase instruments.
