IV. The system works:
1. Ultrasonic principle:
High-frequency current generated by the ultrasonic generator, ultrasonic transducer through the piezoelectric effect to convert the mechanical wave with the frequency to form intensive ultrasonic transducer along the longitudinal axis
To pass cleaning fluid, cleaning fluid produced in the tens of thousands of tiny air bubbles, these bubbles nuclear vertical transmission of negative pressure in the ultrasonic zone formation and growth, and positive pressure area in the rapidly
Rupture. The tiny bubble formation, growth and rapid breakdown of the process is called "cavitation effect." In the cavitation occurs, the tiny air bubbles from the production, growth and rapid fracture
Moment of the formation of more than 1,000 transient atmospheric pressure, the instantaneous pressure as a continuous series of small bombs continue to bombard the surface clean, so that the surface, cracks
And blind holes in the dirt attachments quickly falling off, cavitation erosion effect of this role is the basic principle of ultrasonic cleaning. With suitable cleaning agent, to achieve the efficiency of fast wash
Fruit.
