ultrasonic  transducer is generated by ultrasonic vibration, cavitation occurs in the water the moment generated by the impact of high pressure bubble material to be cleaned to achieve good cleaning results. Ultrasonic cleaning transducer commonly used horn and cylindrical composite stream of the structure, which consists of front and rear metal cover, the piezoelectric ceramic wafer, pre-stressed screw, electrode, and insulating sleeve. Apply appropriate pre-stressed, the transducer in the high power, high amplitude conditions with good mechanical and electrical conversion efficiency. Ultrasonic transducer is a continuous work in the power-type transducer, generally continuous and constant to calculate the average size of its power.
