OURS Production High Performance 100KHZ High Frequency Industrial Ultrasonic Bath Transducers

The mechanism of ultrasonic cleaning is to make use of the physical effects such as cavitation, radiation pressure and sound flow in the cleaning liquid. It can exfoliate the machinery produced by the dirt on the cleaning parts, and can also promote the chemical reaction between the cleaning liquid and the dirt, so as to achieve the purpose of cleaning the object. The frequency of the ultrasonic cleaning machine can be selected by 10~500 kHz according to the size and purpose of the cleaning material, generally more than 20~50 kHz. With the increase of the frequency of ultrasonic transducer, Langerhans oscillator, longitudinal oscillator and thickness oscillator can be used. In the miniaturization aspect, radial vibration and flexural vibration are also adopted. Ultrasonic cleaning has become more and more widely used in various industries, agriculture, household equipment, electronics, automobile, rubber, printing, aircraft, food, hospital and medical research.

The transducer uses different piezoelectric materials to explain that:
The black chip is P4 series, which is a medium power emitting material with dual transmitting and receiving characteristics.
With low dielectric loss and high mechanical quality factor, it is mainly used in ultrasonic cleaning, ultrasonic atomization and so on.
The Yellow chip is P8 series, which is a high-power emission material with high mechanical quality factor.
Good stability, very low dielectric loss, especially suitable for making high-power ultrasonic transducers. Widely used in
Ultrasonic welding, ultrasonic emulsification, ultrasonic polishing, ultrasonic cleaning and so on.

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.
