Hot Sales 28KHZ 100W PZT4 or PZT8 Piezoelectric Ultrasonic Transducer For Submersible Ultrasonic Transducer

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 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 working 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 of 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.

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.

Main Features:
