"Ultrasonic transducer" is commonly known as "ultrasonic oscillator" or "ultrasonic oscillator." Used for ultrasonic cleaning industry, known as the "ultrasonic cleaning transducer."
The ultrasonic cleaning transducer usually adopts horn-type composite oscillator structure (belonging to Langevin oscillator structure), which consists of front and rear metal cover, piezoelectric ceramic chips, pre-stressed screw, electrode slice, and insulating sleeve. Imposed by appropriate pre-stress, the transducer has good mechanical and electrical conversion efficiency under high power and large-amplitude conditions.
It is through the ultrasonic vibration-wave of the transducer occurring cavitations in the water and generates high-pressure vacuole to impact the cleaning materials, so as to achieve an excellent cleaning effect.
