Summation of high-frequency Langevin transducers vibrations for increasing of ultrasonic radiator power.

This article presents the results of the development and study of an ultrasonic radiator (US radiator) of increased power, which is designed for control, location, cavitation processing of liquids, and coagulation of foreign particles in a gaseous media at frequencies from 30 to 90 kHz. The proposed method of vibration summing of low-power high-frequency Langevin transducers on a diametrically vibrating the summing radiating element (summator) allowed developing such a US radiator. The selecting of shape and the search of optimal dimensions allowed creating real designs of US radiator with operating frequency up to 90 kHz.

Ultrasonic Transducer With Increased Exposure Power and Frequency up to 100 kHz.

A new design of a high-frequency piezoelectric transducer with a power from 70 to 1800 W (designed for radiation into liquids and gases of ultrasonic (US) vibrations in the frequency range of 30,…,100 kHz) is proposed. It is based on the principle of summation on a diametrically vibrating summing plate of vibrations of radially mounted Langevin transducers. The method of their design was created and the optimal design dimensions of the transducers were established.
