40K100K160K Multi Frequency diy Ultrasonic Cleaning Vibration Transducer For Washing Precision Instruments

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
The black chip is the P4 series. This type of piezoelectric material is a medium power emission type material with dual characteristics of transmission and reception.
With low dielectric loss and high mechanical quality factor, it is mainly used in ultrasonic cleaning and ultrasonic atomization.
The yellow chip is the P8 series. This type of piezoelectric material is a high-power emitting material. Its main characteristics are high mechanical quality factor.
Good stability, very low dielectric loss, especially suitable for making ultrasonic transducers for high power transmission. widely used in
Ultrasonic welding, ultrasonic emulsification, ultrasonic polishing, ultrasonic cleaning, etc.
 
Comparison of different chip transducers:
1). The absolute value of the capacitance change of the yellow chip assembled transducer is low, and the strong field loss is small. Therefore, compared with the same driving circuit, the heat generation is low and the heat is stable. The water spray is stable to the change of the cleaning load and has a large impact, which is in the middle of the rules.
 
2). The transducer of the black chip has a high electromechanical coupling coefficient and a high Curie temperature, so the electroacoustic conversion efficiency is high. And it has higher stability and higher temperature resistance than other products using general P4 series. Water spray is high in water column and rich in bubbles, but it has high sensitivity to changes in cleaning load.
 
3). Application occasions (recommended): high frequency (such as above 40K) or low power transducer (less than 60W) is assembled with black chips
The transducer, low frequency or high power transducer uses yellow chip assembled transducer.
