Ultrasonic cleaning is the use of ultrasonic cavitation in liquid, acceleration and straight into the flow of liquid and dirt of direct and indirect effect, make the dirt layer from the workpiece surface is clean dispersion, emulsification, stripping and to achieve. Currently used ultrasonic cleaning machine, cavitation and straight into the flow function application more.

Function: (1) cavitation cavitation is ultrasonic compression force and more than twenty thousand times per second interactive way of high frequency transformation to the liquid pressure reduction transmission. When reducing pressure, the phenomenon of vacuum nuclear group of bubbles in the liquid, the compression force, the nuclear group of vacuum bubble pressure produced in powerful impact crushing, thus stripping surfaces to be cleaned of dirt, so as to achieve the purpose of cleaning.

In ultrasonic cleaning process, the naked eye can see floating bubbles are not vacuum nuclear group of bubble, but the air bubbles and its inhibitory effect on cavitation reduce cleaning efficiency. Only the air bubbles in the liquid is completely off, cavitation bubble of vacuum nuclear group to achieve the best effect. So some cleaning process degassing is used to achieve precision cleaning effect.

(2) straight into the flow function: ultrasonic wave in the liquid along the direction of sound waves to produce flow phenomenon called straight into the stream. Acoustic intensity in a certain density (0.6 W/cm2), to the naked eye can see straight into the stream, perpendicular to the vibrating surface flow, the velocity of about 10 cm/s. Through the straight into the flow by cleaning micro oil dirt on the surface of the object by stirring, the dirt on the surface of the cleaning fluid also cause convection, dissolving dirt dissolved liquid mixed with new fluid, dissolving speed, transportation plays a big role of dirt.

(3) acceleration: liquid particles to promote the acceleration. For high frequency ultrasonic cleaning machine (such as 40 KHZ), cavitation effect is not significant, the ultrasonic cleaning mainly by liquid particles under the action of the acceleration of the impact of dirt particles ultra-precision cleaning.
