In supersonic wave cleaning machine at present used, cavitation and acoustic streaming effect answer land used more, and Ultrasonic Cleaning is widely used in the industries such as surface spraying treatment industry, machinery industry, electron trade, medical industry, semicon industry, clock and watch jewellery industry, optics industry, textile printing and dyeing. Supersonic wave cleaning machine is mainly made up of high-quality high-performance ultrasonic transducer rinse bath and special supersonic generator, and supersonic generator and rinse bath can be split or one.
Ultrasonic cleaner mainly contains two kinds at present, be two kinds of traditional open ultrasonic cleaning tank and immersion ultrasonic cleaners: in traditional immersion ultrasonic cleaner, under the duty of ultrasonic transducer in single side radiation, previous irradiation face and the ultrasonic cleaner of sandwich piezoelectric ceramics composite transducer are combined closely, to realize hyperacoustic high efficiency of transmission; And another radiating surface of transducer, the rear radiating surface of the transducer of namely often saying, is exposed aerial. Due to the wave amplitude position that the rear radiation end face of transducer is transducer vibrations displacement, although the impedance of air is very low, because displacement is larger, therefore the backward radiation power of transducer can not be zero. Meanwhile, due to air impedance and the serious mismatch of transducer impedance, will produce serious sound reflecting at the rear radiating surface place of transducer, thereby cause the power attenuation of transducer, reduce the efficiency of transducer. In order to reduce the backward radiation power of this type of transducer as far as possible, people adopt the back shroud material of common heavy metal material as transducer. After adopting this measure, although the backward radiation power of minimizing transducer that can be suitable, but still there is the reflection problems of sound wave.
