60W 28KHZ Ultrasonic Oscillator Piezoelectric Transducer For Ultrasonic Dishwasher Cleaning

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.

1. Ultrasonic vibrator mainly consists of several parts such as shell, acoustic 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 the general transducer, mainly used to transmit and receive ultrasonic waves; and above the piezoelectric ceramic disc transducer is the Cymbal array receiver, It is mainly composed of lead-out cable, Cymbal transducer, metal ring and rubber gasket. It is used as an ultrasonic receiver to receive the Doppler return signal generated outside the frequency band of the piezoelectric ceramic disc transducer.
3. The ultrasonic dishwasher vibrator is actually a piezoelectric ceramic with the same frequency as its resonance frequency, which uses the piezoelectric effect of the material to convert electrical energy into mechanical vibration. Generally, ultrasonic waves are first generated by an ultrasonic generator, which is converted into mechanical vibration by an ultrasonic transducer, and then ultrasonic waves can be generated by an ultrasonic deriving device and an ultrasonic receiving device.
