Vibratory Systems and Equipment for Ultrasonic Cleaning
The main factor governing the second-order effects basic to ultrasonic cleaning is the ultrasonic field generated in the technological working volume by means of the ultrasonic vibratory system, which comprises a transducer, matching element, and radiator. The input parameters (on the electrical side) of the transducer determine the requirements on the ultrasonic generators, while the design and output (acoustical) characteristics of the radiator determine the operational characteristics of the technological equipment. An alternating mechanical force is created in the transducer (which is the active element of the vibratory system) by virtue of the magnetostriction or piezoelectric effect. The passive matching element of the system transforms the velocities and mode of the vibrations and matches the external load impedance and internal impedance of the active element. The passive element terminates in the radiator, which produces the ultrasonic field in the liquid. The radiator can be made in the form of an independent component or combined with the matching and transforming device .
