Ultrasonic cavitation threshold and the frequency of ultrasound is closely related to the higher the frequency, the higher the cavitation valve. Ultrasonic cleaning machine in other words, the lower the frequency, the easier to produce cavitation, and in the case of low-frequency liquid subject to compression and thinning effect has a longer time interval, so that the bubble can grow to a larger size before collapse, increasing the strength of cavitation, which is conducive to cleaning action. So low-frequency ultrasonic cleaning is suitable for large parts surface or dirt and cleaning the surface of the high degree of bonding occasions. But easy to corrode the surface of the cleaning parts, not suitable for cleaning parts with high surface finish, and cavitation noise. 40 KHZ or so frequency, in the same sound intensity, the number of cavitation bubbles generated than the frequency of 20 KHZ, the penetration force is stronger, suitable for cleaning the surface of complex shapes or blind holes in the workpiece, cavitation noise is smaller, but the cavitation strength is lower, suitable for cleaning dirt and the surface of the cleaned parts with a weaker bond. occasions. High-frequency ultrasonic cleaning is suitable for computers, microelectronic components of fine cleaning; megahertz ultrasonic cleaning is suitable for integrated circuit chips, silicon wafers and wave film cleaning, can remove micron, submicron level dirt without any damage to the cleaning parts. Therefore, from the cleaning effect and economic considerations, the frequency is generally selected in the range of 20-130KHZ, of course, the correct choice of frequency is essential, and the specific selection of the appropriate working frequency needs to do some experiments to obtain.
