Ultrasonic cleaning equipment is composed of high-frequency oscillation signals emitted by ultrasonic generators, which are converted into high-frequency mechanical oscillations by transducers and then propagated into the medium - the cleaning solvent. Ultrasonic waves radiate forward in the cleaning liquid with alternating dense and sparse areas, causing the liquid to flow and generate tens of thousands of diameters of 50-500μm The tiny bubbles existing in the liquid vibrate under the action of the sound field.
What are the important performance parameters to consider when evaluating the quality of an ultrasonic cleaner? Why is 28 KHZ to 40 KHZ usually chosen for the same range? What kind of proof is this? The higher the frequency, the better? Higher frequency, greater cavitation effect?
The most important thing is still to see if you are washing things. Rough, the appearance of the objects to be washed has no strict requirements, low frequency, and deal with some mesh washing with high frequency, too low ultrasonic cavitation effect. Next, let's look at the selection of the washing medium. For SUS 304 steel plates, weakly alkaline medium is still not required. Weakly acidic medium is still not necessary as it is prone to acidification on the surface and aging of the steel plate.
The same skill load index of ultrasonic cleaners, including aging degree, vibration, impedance and inductance, is usually debugged before leaving the factory. The key lies in what you are going to use it for. Of course, the sounds of current ultrasonic cleaners and ultrasonic generators are basically synchronized, that is, resonant. This needs to be accomplished by a professional manufacturer, such as NVC Ultrasonic. The vibrator of the adhesive is usually consolidated in a special way. Although the bolt tightening effect is good, it is not easy to repair.
The choice of frequency is a proven decision. It may be due to the fact that the appearance of the material usually does not have very high requirements. At 28 KHZ, it is best to choose a high frequency for washing a severe or closed part. This is because at lower frequencies, the larger the bubbles produced, when the ultrasonic frequency exceeds 800 kilohertz, there will be empty foam. Therefore, the result of cavitation and spoilage of the items that need to be washed is the lowest.
