Based on the cavitation effect of ultrasound in liquids, the transducer transfers electrical energy Through the amplitude-variable rod in the liquid at the top of the tool head to produce high-intensity shear force the formation of high-frequency alternating water pressure intensity so that the cavity expansion, explosion will be broken cells. in addition,the use of ultrasonic propagation in the liquid to produce violent perturbation effect, so that the particles produce a large acceleration.thus colliding with each other or collision with the wall to achieve theeffect of crushing, emulsification and separation.
