33K80K135K 40W PZT-4 Multi-Frequency High Stability Variable Frequency 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.

1. The ultrasonic vibrator mainly consists of the shell, sound window (matching layer), piezoelectric ceramic disc transducer, backing, lead-out cable, Cymbal array receiver, etc.
2. Among them, the piezoelectric ceramic disc transducer plays the same role as a general transducer, and is mainly used to transmit and receive ultrasonic waves. On top of the piezoelectric ceramic disc transducer is a Cymbal array receiver. It is mainly composed of a lead-out cable, a Cymbal transducer, a metal ring, and a rubber washer. It is used as an ultrasonic receiver to receive Doppler callback signals generated outside the frequency band of the piezoelectric ceramic disc transducer.
3. The ultrasonic dishwasher oscillator is actually a piezoelectric ceramic with the same frequency as its resonance frequency. It uses the piezoelectric effect of the material to convert electrical energy into mechanical vibration. Generally, the ultrasonic wave is first generated by an ultrasonic generator, converted into mechanical vibration by an ultrasonic transducer, and then generated by an ultrasonic derivation device and an ultrasonic receiving device.

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.
