The influence of high and low frequencies
The ultrasonic cavitation threshold is closely related to the frequency. The higher the frequency, the higher the cavitation threshold. The lower the frequency, the lower the cavitation threshold, and the more likely cavitation is to occur. At low frequencies, the time interval between liquid compression and thinning is longer. Bubbles can grow to larger sizes, enhancing the cavitation intensity and facilitating the cleaning effect. Therefore, low-frequency ultrasonic cleaning is generally used on the surfaces of large parts or workpieces where the adhesion of dirt is high. But it is prone to damaging the surface of the workpiece. Therefore, ultrasonic cleaning machines are not suitable for parts with high requirements for the surface of the workpiece at lower frequencies. Moreover, with a low frequency, the noise generated is correspondingly greater.
2. Select the frequency according to different situations
High-frequency ultrasonic waves have strong penetrating power. Therefore, it is recommended to clean and wash parts with high surface finish requirements or complex surfaces with many blind holes. On the other hand, high-frequency ultrasonic waves have low noise and are suitable for cleaning some precision parts, such as some electronic components, small bearing processing, magnetic materials, etc. For the cleaning of some special workpieces such as integrated circuit chips and silicon wafer coatings, ultrasonic cleaning with a higher frequency is recommended. For some large workpieces, such as car engines and valves, low-frequency ultrasonic cleaning should be selected. On the other hand, considering the cleaning effect and economy of ultrasonic waves, the frequency is generally selected within the range of 20 to 130KHz. The specific selection frequency is determined by the corresponding experiments.
The above is some introduction to the frequency of ultrasonic cleaning machines. I hope it can help everyone. Ultrasonic cleaning machines are widely used in many fields and have achieved remarkable results. To maintain this effect, we should carry out daily maintenance on the machine, promptly repair faults and ensure the working performance of the washing machine.
