How to judge the quality of ultrasonic cleaning equipment

Ultrasonic cleaning equipment is the high-frequency oscillation signal emitted by the ultrasonic generator, which is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium-cleaning solvent. The flow produces tens of thousands of tiny bubbles with a diameter of 50-500 μm, and the tiny bubbles existing in the liquid vibrate under the action of the sound field.

What are the important performance parameters for evaluating the quality of an ultrasonic cleaner? Why the same usually choose 28 kHz to 40 kHz. What proof is this sure? The higher the frequency, okay? Higher frequencies, greater cavitation effects?

The most important thing is to see what you are washing, rough, no harsh requirements on the appearance of the washed object, low frequency, and deal with some of the most mesh washing frequencies with high, too low ultrasonic cavitation effects. Next, we will see the choice of washing medium, SUS 304 steel plate with weak alkaline medium, weak acidity is still not required, it is easy to form acidification on the surface, and the steel plate will deteriorate.

The same skill load index of the ultrasonic cleaning machine is usually the aging degree and vibration, impedance, and inductance of the room are debugged before leaving the factory, the key is what you use it for. Of course, the sound of the current ultrasonic cleaner and the ultrasonic generator are basically synchronized, that is, resonance. This needs to be done 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 suitable for maintenance.

The choice of frequency is a proven decision, probably not very demanding for the appearance of the material, with 28 kHz, washing up a severe, or closing part is best to choose a high frequency. This is because, at lower frequencies, the larger the bubbles produced, the more ultrasonic frequency is over 800 kHz, and there are empty bubbles, so the result of cavitation and corruption in the things to be washed is the lowest.
