(1) Cavitation: Cavitation is the transmission of ultrasonic waves to a liquid by a high-frequency transformation of compressive force and pressure reduction interaction of more than 20,000 times per second. When the pressure is reduced, a phenomenon of a vacuum core group bubble is generated in the liquid. When the compressive force acts, the vacuum core group bubble generates a strong impact force when crushed by the pressure, thereby peeling off the dirt on the surface of the object to be cleaned, thereby achieving precision. Washing purpose.
(2) Straight inflow: The phenomenon that ultrasonic waves flow in the direction of sound propagation in the liquid is called straight flow. When the sound wave intensity is 0.5 W/cm2, the naked eye can see a straight flow, and a flow is generated perpendicular to the vibration surface at a flow rate of about 10 cm/s. Through this straight flow, the micro-oil dirt on the surface of the object to be cleaned is stirred, and the cleaning liquid on the surface of the dirt is also convected. The dissolved solution of the dissolved dirt is mixed with the new liquid, so that the dissolution rate is accelerated, and the handling of the dirt is very good. Great role.
(3) Acceleration: The acceleration generated by the liquid particles. For the ultrasonic cleaning machine with higher frequency, the cavitation effect is not significant. At this time, the cleaning mainly relies on the acceleration of the liquid particles under the action of ultrasonic to impact the particles to ultra-precision cleaning of the dirt.
