Ultrasonic cleaning machine frequency difference

- May 05, 2019-


In the case of low frequencies, the time during which the liquid is pressed and pulled becomes longer; therefore, the cavitation is generated for a longer period of time and the volume is also longer, and the impact force generated when cavitation is closed is proportional to the size of the cavitation bubbles. So the lower the frequency, the stronger the cavitation.

The frequency we use in industrial cleaning is generally less than 60KHz, and the most used is between 20 and 40KHz. Using a frequency of around 20 kHz, a relatively small number of cavitation bubbles can be obtained, but with large cavitation intensity and noise, it can be used to clean workpieces with high bonding strength between the surface of large parts and the surface of objects. At a frequency of about 40 kHz, the number of cavitation bubbles generated under the same sound pressure is large, but the cavitation intensity generated during the crushing is low, the noise is small, the penetrating ability is strong, and the surface is complicated, blind holes, dirt and Workpiece with weak surface bonding.

The ultrasonic cleaning machine frequency range from 25khz to 200khz, we can make it according to your requirements and applications.
