How to set the frequency of the ultrasonic cleaner

Under normal circumstances, the frequency of the ultrasonic cleaner when it is used determines the cleaning effect of the ultrasonic cleaner for a lot of time. The ultrasonic cavitation threshold is closely related to the frequency of the ultrasonic cleaning machine. The higher the frequency, the higher the cavitation valve. That is to say: the lower the frequency, the easier the cavitation occurs, and at low frequencies, the liquid is compressed and thinned for a longer time interval, so that the bubbles can grow to a larger size before disintegration. Therefore, we can improve the cleaning efficiency by increasing the cavitation intensity.

The frequency of the ultrasonic cleaner is the core of the ultrasonic cleaner technology. We all know that when the working frequency is very low (within the range of human hearing), noise will be generated. When the frequency is lower than 20kHz, the working noise not only becomes large, but also may exceed the limits of the safety noise prescribed by the Occupational Safety and Health Act or other regulations. In applications that require high power to remove dirt without regard to workpiece surface damage, a lower cleaning frequency in the range of 20kHz to 30kHz is usually selected. The cleaning frequency in this frequency range is often used to clean large and heavy parts or high-density materials.
