Product Description

Ultrasonic vibrator is also called ultrasonic vibrator. In the industry, the whole connected with transducer and horn is called vibrator.
The ultrasonic vibrator realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and is a device that is amplified by the front and rear radiation cover blocks matched with acoustic impedance. The frequency is fixed during production and can be According to the needs of customers, the transducers with different frequencies are customized, and the transducer vibrator produced can only be fixed at this frequency. In fact, the ultrasonic cavitation threshold is closely related to frequency. The higher the frequency, the higher the cavitation threshold. The lower the frequency and the lower the cavitation threshold, the easier it is to produce cavitation.
At low frequencies, the time interval between compression and thinning of the liquid is longer. The bubbles can grow to a larger size, enhance the cavitation strength, and facilitate the cleaning effect. Therefore, low-frequency ultrasonic cleaning is generally used when the surface of large parts or the adhesion of dirt and the surface of the workpiece is high. But it is easy to damage and corrode the surface of the workpiece. Therefore, parts with higher requirements on the surface of the workpiece are not suitable for lower frequencies. And the frequency is low, the noise produced is correspondingly too big. High-frequency ultrasonic waves have strong penetrating power, so it is advisable to clean the parts with higher surface finish requirements or complex surfaces and more blind holes.
On the one hand, the noise of high-frequency ultrasound is also small, which is suitable for cleaning some precision parts, such as some electronic parts, small bearing processing, and magnetic materials. For the cleaning of some special workpieces such as integrated circuit chips and silicon wafer coatings, it is advisable to choose higher frequency ultrasonic for cleaning. For some large workpieces such as automobile engines, valves and other large workpieces, low-frequency ultrasonic waves should be selected for cleaning.
On the other hand, considering the effect of ultrasonic cleaning and economy, the frequency is generally selected at 20~130KHz. The specific selection frequency should be determined by corresponding experiments. To sum up, the frequency of the ultrasonic vibrator is fixed, so during production, there will be continuous procedures for testing whether the frequency is qualified, and the production will be strictly in accordance with the requirements.


The ultrasonic cavitation threshold is closely related to the frequency of ultrasonic waves. The higher the frequency, the higher the cavitation valve.
In other words, the frequency is low, the more cavitation is generated, and the liquid is compressed and sparsed for a longer time interval at low frequencies, so that the bubbles can grow to a larger size before disintegration. Cavitation strength is conducive to cleaning.
 
Therefore, low-frequency ultrasonic cleaning is suitable for the appearance of large parts or places where the combination of dirt and the appearance of cleaning parts is high. However, the surface of the cleaning parts is easy to be corroded, and it is not suitable for cleaning the parts with high surface finish, and the cavitation noise is large. At a frequency of about 40KHZ, under the same sound intensity, there are more cavitation bubbles than when the frequency is 20KHZ, and the penetrating power is stronger. It is suitable to clean the workpiece with complex appearance or blind holes. The cavitation noise is small, but the cavitation The strength is low, and it is suitable for places where the bond between the dirt and the surface of the cleaned part 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 economy, the frequency is generally selected in the range of 20-130KHZ. Of course, the correct selection of the frequency is very important, and the selection of the specific and appropriate working frequency requires certain experiments to obtain.
 

The ultrasonic vibration plate and ultrasonic generator constitute the core components of the ultrasonic cleaning machine, which determine the cleaning quality of an ultrasonic cleaning machine. Therefore, when choosing a suitable ultrasonic cleaning machine, you must understand the frequency of the ultrasonic vibrator and the choice of the generator.

Tips for selecting ultrasonic vibrator frequency:
Everyone knows that the inside of the vibration plate is composed of ultrasonic vibrators. When the working frequency of the cleaning machine is very low (within the range of human hearing), noise will be generated. When the frequency is lower than 20kHz, the work noise not only becomes very loud, but may exceed the safety noise limit stipulated by the Occupational Safety and Health Law or other regulations. In applications that require high power to remove dirt without considering the surface damage of the workpiece, a lower cleaning machine frequency in the range from 20kHz to 40kHz is usually selected. The cleaning frequency in this frequency range is often used to clean large, heavy parts or high-density materials. The ultrasonic vibrators produced by Boda Ultrasonic have two fixed low-frequency ultrasonic vibrators of 28KHZ and 40KHZ.
 
High frequency is usually used to clean smaller, more precise parts, or to remove tiny particles. High frequency is also used in applications where the surface of the workpiece is not allowed to be damaged. Using high frequency can improve cleaning performance in several ways. As the frequency increases, the number of cavitation bubbles increases linearly, which generates more and denser shock waves that can enter smaller gaps. If the power remains the same, the cavitation bubble becomes smaller, and the energy released by it 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 (Ponury effect), so that ultrasound can'discover' extremely fine particles. And our Boda high frequency ultrasonic vibrator also has 68KHZ, 80KHZ, 100KHZ, 120KHZ.
