The principle of the ultrasonic cleaning machine is mainly to convert the sound energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and to irradiate the ultrasonic wave into the cleaning liquid in the tank through the cleaning tank wall. Due to the radiation of the ultrasonic waves, the microbubbles in the liquid in the tank can be kept vibrated by the action of the sound waves. The adsorption of the dirt and the surface of the cleaning member is destroyed, causing fatigue damage of the dirt layer to be rejected, and the vibration of the gas type bubble scrubs the solid surface.

Ultrasonic wave is a sound wave with a frequency higher than 20,000 Hz. It has good directionality, strong penetrating ability, easy to obtain concentrated sound energy, and has a long distance in water. It can be used for distance measurement, speed measurement, cleaning, welding, crushing, sterilization. Wait. There are many applications in medicine, military, industry, and agriculture. Ultrasound is named because its lower frequency limit is approximately equal to the upper limit of human hearing.

"Ultrasonic cleaning process technology" refers to the use of ultrasonic cavitation to impact and peel off the dirt on the surface of the parts to achieve cleaning purposes. It has the characteristics of high cleaning cleanliness and fast cleaning. Especially for blind holes and various geometric parts, there are unique cleaning effects that cannot be achieved by other cleaning methods.

The ultrasonic wave propagating in the liquid can clean the dirt on the surface of the parts. The principle can be explained by the phenomenon of "cavitation": when the ultrasonic wave propagates in the liquid to a pressure of one atmosphere, the power density is 0.35w/cm2. At this time, the peak of the ultrasonic wave pressure can reach the vacuum or the negative pressure, but in fact no negative pressure exists, so a large force is generated in the liquid, and the liquid molecules are pulled into a cavity and a cavitation nucleus. This cavity is very close to the vacuum, which ruptures when the ultrasonic pressure is turned back to the maximum, and the strong impact due to the rupture strikes the dirt on the surface of the object. This shock wave phenomenon caused by the cracking of numerous small cavitation bubbles is called the "cavitation" phenomenon.
