120Watt Vibration High Power Ultrasonic Cleaning Transducer/Vibrator/Sensor/Radiator 28K For Automotive Parts Cleaner 

The ultrasonic cavitation threshold is closely related to the frequency of the ultrasonic wave. The higher the frequency, the higher the cavitation valve.

In other words, the ultrasonic dishwasher machine has a low frequency, and the cavitation is more likely to occur, and the liquid is subjected to compression and sparse action at a low frequency for a longer time interval, so that the bubble can grow to a larger size before being disintegrated, and the height is increased. The cavitation strength is good for cleaning.

Therefore, low-frequency ultrasonic cleaning is suitable for places where the appearance of large parts or the combination of dirt and cleaning parts is high. However, it is easy to corrode the surface of the cleaning part, and it is not suitable for cleaning the parts with high surface finish, and the cavitation noise is large. The frequency around 40KHZ, under the same sound intensity, the number of cavitation bubbles is more than the frequency of 20KHZ, the penetration is strong, it is better to clean the workpiece with complex shape or blind hole, the cavitation noise is small, but cavitation The strength is low, and it is suitable for cleaning the place where the dirt and the surface of the part to be cleaned are weak.

High-frequency ultrasonic cleaning is suitable for computer and micro-electronic components. Micro-ultrasonic cleaning is suitable for cleaning integrated circuit chips, silicon wafers and wave films. It can remove micron and sub-micron dirt without any damage to 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 selection of the frequency is crucial, and the selection of the specific suitable working frequency needs to be done experimentally.

Ultrasonic vibration plate and ultrasonic generator form the core components of the ultrasonic cleaning machine, which determines the cleaning quality of an ultrasonic cleaning machine. Therefore, you must know the ultrasonic vibrator frequency and generator selection when choosing a suitable ultrasonic cleaning machine.
