Ultrasonic cleaning machine principle: the principle of ultrasonic cleaning machine is mainly through the transducer frequency ultrasonic sound power source can be converted into mechanical vibrations by the ultrasonic cleaning tank wall radiation to the trough in the cleaning fluid. Due to the ultrasonic wave irradiation, so that the liquid in the tank under the action of micro-bubbles can thereby maintain sonic vibration. Destruction of dirt and cleaning the surface adsorption, causing fatigue failure dirt layer is split off, the vibration type gas bubbles scrub the surface of the solid.
