2000W 28KHZ/40KHZ High Power Ultrasonic Generator Variable Frequency Ultrasonic Industrial Cleaning Generators

The principle of a self excited sweep frequency ultrasonic generator is to provide power to the control circuit, which outputs a pulse switch signal and drives the power amplification circuit. The amplified switch signal is boosted and matched with the LC circuit, outputting a sine wave and driving the ultrasonic transducer to work in a resonant state, outputting strong ultrasonic mechanical vibration waves. A transducer, also known as a vibrator, is a device that converts electrical energy to mechanical energy (acoustic vibration) through the piezoelectric effect of piezoelectric ceramics, and amplifies it through front and rear radiation cover blocks that match the acoustic impedance. The ultrasonic cleaning transducer generally adopts a horn type composite array sub structure (belonging to the Langevin vibration Substructure), which is composed of front and rear metal cover plates, piezoelectric ceramic chips, pre-stressed screws, electrode pieces, and insulating sleeves. By applying appropriate prestress, the transducer has good electromechanical conversion efficiency under high-power and high amplitude conditions. Compared with the fixed frequency ultrasonic generator, the fixed frequency ultrasonic generator of this utility model has a fixed frequency ultrasonic efficiency of only 5% and 25%, which makes it necessary to resort to external heating methods for cleaning. The ultrasonic oscillator effect of this utility model’s excitation type sweep frequency ultrasonic generator reaches 85%, and there is basically no blind spot on the cleaned object. The alternating peak valley in the direction of sound wave transmission is significantly weakened, achieving the goal of uniform cleaning. Compared with the self-excited ultrasonic generator, the self-excited ultrasonic generator of this utility model cannot track the resonant frequency in a timely manner
