    The multi slot manual ultrasonic cleaning machine is closely related to frequency. The higher the frequency, the higher the cleaning effect. The lower the frequency, the lower the cleaning effect, and the easier it is to produce cavitation. At low frequencies, the time interval between compression and sparsity of liquids is longer. Enable bubbles to grow to larger sizes, enhance cavitation intensity, and facilitate cleaning. So low-frequency ultrasonic cleaning is generally used on the surface of large components or when the adhesion between dirt and the workpiece surface is high. But it is easy to damage and corrode the surface of the workpiece. So parts with high surface requirements for workpieces are not suitable for choosing lower frequencies. Moreover, the frequency is low and the generated noise is correspondingly high. High frequency ultrasonic waves have strong penetration power and are suitable for cleaning parts with high surface smoothness requirements or complex surfaces with many blind holes.

    On the other hand, the noise of high-frequency ultrasound is also relatively low, making it suitable for cleaning some precision parts, such as electronic components, small bearing processing, magnetic materials, etc. For some special workpieces such as integrated circuit chips and silicon wafer coatings, it is advisable to use higher frequency ultrasonic waves for cleaning. For some large workpieces such as car engines, valves, etc., low-frequency ultrasonic waves should be selected for cleaning. On the other hand, considering the effectiveness and economy of ultrasonic cleaning, the frequency is generally selected between 20-130KHz. The specific frequency selection should be determined through corresponding experiments.

    3. Cleaning process: Choose a reasonable ultrasonic cleaning equipment process based on the characteristics and pollution of the workpiece. You can consult relevant personnel for advice in this regard, or ask the manufacturer to provide process experiments to improve the cleaning process. The selection of cleaning process is an important part before equipment manufacturing, and it is necessary to choose the correct process, otherwise it will affect the long-term cleaning effect in the future.

    The strength of power is a direct determining factor for the cleaning effect and cleaning time of workpieces. The strength of power is determined by the structure of the workpiece and the placement of the workpiece in the groove to choose the radiation distribution of ultrasonic waves. To calculate the required ultrasonic power for the emitting surface. The calculation of ultrasonic power is carried out using the internationally recognized standard method. Generally speaking, the cleaning frequency of ultrasonic cleaning machines is selected between 28KHZ and 40KHZ, which are more common. Only those that require extremely small particles on the surface of the workpiece and do not allow damage to the surface should choose higher frequencies.
