The ultrasonic cleaning machine is widely used in fields like hospitals, pharmacies, schools, scientific researches, petroleum, chemical industry, light industry, metallurgy, machines, transportations, national defenses etc. Currently it's an ideal, efficient and accurate cleaning equipment to clean thoroughly the instrument, meter, electronic device, circuit board, silicon dice of a semiconductor, magnetic material, galvanized parts, hardware, optical lens, audio-frequency magnetic head, terylene filtering core, spinneret, latex mold, medical apparatus, glassware, bijouterie, parts of a clock and watch, fine metal, bearing, nozzle, oil pump and parts in manufacturing machine and some shape-complicated parts, especially the deep hole, blind hole and concavo-convex surfaces. The ultra-audio-frequency electric signal produced by the ultrasonic generator in a ultrasonic cleaning machine is conversed to the mechanical vibration with the same frequency through the piezoelectric inverse-transforming effect of the transducer, and then it will radiate forward intensively in the cleaning solution in the form of ultra-audio-frequency longitudinal wave(The ultra-audio frequency longitudinal wave spreads alternatively between zones of negative pressure and positive pressure), producing ten thousands of small bubbles to explode in turn. It's these small bubbles which form and grow in the zone of negative pressure, and explode instantaneously in the zone of positive pressure, to strike with high pressure the surface, gap, and small local of a cavity to be washed, leading to peeling off of fouling quickly, thus the good cleaning and purifying effect can be reached.
