Piezoelectric transducer for making ultrasonic cleaner and cleaning tank
Transducer, also known as vibrator, is a device that converts the electrical energy and mechanical energy (sound wave vibration) by the piezoelectric effect of piezoelectric ceramics and amplifies the acoustic impedance matching front and rear radiation cover blocks.
Ultrasonic cleaning ultrasonic vibration generated by the transducer, cavitation occurs in the water generated by the instantaneous impact of high-pressure foam was washed to achieve a good cleaning effect.
Ultrasonic cleaning transducers generally use the horn-type composite matrix structure (which is Lan Jie Wenzizhu structure), which consists of front and rear metal cover, piezoelectric ceramic wafer, prestressed screw, electrode sheet, and insulating sleeve. Apply appropriate prestress, the transducer in high-power, high-amplitude conditions have good electromechanical conversion efficiency.
Ultrasonic cleaning transducer is a continuous work of the power transducer, generally the average continuous operation to calculate the constant and its power size.
ultrasonic cleaning transducer:
◊ High efficiency: high mechanical parameter Q, the transduction efficient between electricity and sound above 95%.
◊ High amplitude: the transducer strength is improved by fixing the high speed vibrator directly on the base of washing groove with bolt. Compare with a magnetic expansion vibrator, its amplitude can be improved above 50%.
◊ Good heat resistance: a large range of working temperature, low resonance impedance and heat productivity.
◊ Good construction: fastened by bolt, easy for assembling, high reliability.
widely used in ultrasonic cleaning machine and high-power industry cleaning devices.
