High Performance 25Khz 45Khz 85Khz Multi Frequency Ultrasonic Transducer Operating Voltage For Ultrasonic Cleaning Machine

The ultrasonic cavitation threshold is closely related to the frequency of the ultrasound. The higher the frequency, the higher the cavitation valve.
In other words, the lower the frequency of the ultrasonic dishwasher, the easier it is to produce cavitation, and the longer the time interval between compression and thinning of the liquid at low frequencies, the bubbles can grow to a larger size before disintegration and increase. Cavitation strength is conducive to cleaning.
 
Therefore, low-frequency ultrasonic cleaning is suitable for places with large parts or a high degree of dirt and cleaning parts. However, it is easy to corrode the surface of cleaning parts, it is not suitable for cleaning parts with high surface finish, and the cavitation noise is large. At a frequency of about 40KHZ, at the same sound intensity, the number of cavitation bubbles is more than that at 20KHZ, and the penetrating power is strong. It is suitable to clean workpieces with complex shapes or blind holes. Cavitation noise is small, but cavitation Low strength, suitable for places where the binding force between the dirt and the surface of the object to be cleaned is weak.

High-frequency ultrasonic cleaning is suitable for the fine cleaning of computers and microelectronic components. Megahertz ultrasonic cleaning is suitable for the cleaning of integrated circuit chips, silicon wafers and wave films. It can remove micron and sub-micron dirt without any damage to the cleaning parts. Therefore, from the consideration of cleaning effect and economic efficiency, the frequency is generally selected in the range of 20-130KHZ. Of course, it is important to select the correct frequency, and the selection of a specific and suitable operating frequency requires certain experiments to obtain.
 
The ultrasonic vibration plate and the ultrasonic generator form the core components of the ultrasonic cleaning machine, which determines the cleaning quality of an ultrasonic cleaning machine. Therefore, when selecting a suitable ultrasonic cleaning machine, you must understand the ultrasonic oscillator frequency and the choice of the generator.

High frequencies are often used to clean smaller, more delicate parts, or to remove small particles. High frequencies are also used in applications where damage to the surface of the workpiece is not allowed. The use of high frequencies can improve cleaning performance in several ways. As the frequency increases, the number of cavitation bubbles increases linearly, resulting in more and more dense shock waves that allow them to enter smaller gaps. If the power remains the same, the cavitation bubble becomes smaller, and the energy it releases is correspondingly reduced, which effectively reduces the damage to the surface of the workpiece. Another advantage of high-frequency is that it reduces the viscous boundary layer (Ponnuri effect), allowing ultrasound to 'find' very small particles. And our high-frequency ultrasonic oscillators also have 68KHZ, 80KHZ, 100KHZ, 120KHZ.
