Principles of ultrasonic cleaning machine
By using the liquid cavitation, acceleration, and direct inflow action, the ultrasound impacts directly or indirectly on the filth inside the liquid and reaches the cleaning purpose by dispersing, emulsifying, or peeling off the filthy layer. The cavitation and direct inflow function are more often applied in the currently used ultrasonic cleaning machines. Cavitation function refers to the phenomenon of the rapid formation and inner implosion of the countless air bubbles inside the cleaning reagent. The blast waves generated thereafter wash away or peel off the dirt on the inside or the surface of the workpieces soaking under the cleaning liquid. As the ultrasound frequency increases, the bubbles number increases and the blast force weakens, Therefore, high-frequency ultrasound is especially suitable for the cleaning of small particles without damaging the surface of the workpiece.
Application of ultrasonic cleaning machine
The ultrasound has a very wide application-surface cleaning. For instance, the ultrasound causes vibration of water molecules as it transmits inside the water, If the ultrasonic power is big enough, it could rip the water molecules into an empty hole(cavitation core), inside the empty hole, there forms a vacuum space or space closes to the vacuum. In the enlarging process of the empty hole, it will blast suddenly as its peripheral pressure keeps increasing, the water molecules collide fiercely so that thousands of shock waves will be generated and wash the dirt off the object's surface. Those numerous tiny dense bubbles turning into shock waves process is called as “cavitation effect”.
Generally speaking, the industrial ultrasonic cleaner involves a special cleaning process, so it has more strict requirements such as degerming and anticorrosion function. Therefore, the tank in the ultrasonic cleaning system is normally used with stainless material and equipped with an independent control box to adjust the temperature and cleaning time.
28kHz & 40kHz frequency application
For the cleaning of objects like hardware, mechanical objects, motorcycles, compressors, etc. 28kHz are often used.
For the optical photoelectron and circuit board cleaning, 40kHz is often used. The lower the frequency, the more easily cavitation occurs. Moreover, at low frequencies, the liquid is compressed and sparse at longer time intervals, the bubble will increase to a larger size, and the cavitation is strengthened so as to have a better cleaning result. So low-frequency ultrasonic cleaning is suitable for large parts surface cleaning. At a frequency of about 40 kHz, more cavitation bubbles are generated at the same sound intensity than at a frequency of 28 kHz with stronger penetration. So, it is suitable to clean workpieces with complicated shapes or with blind holes.
