What is the working principle of ultrasonic cleaning machine?

As a cleaning device, ultrasonic cleaning machines can be seen everywhere in the industrial and commercial fields, from laboratories and medical institutions to small eyeglass shops. The shadow of ultrasonic cleaning machines showing their skills can be found everywhere. Although it is an ordinary mechanical product, its function is enormous, and the quality of the cleaning effect directly affects the entire operation process of the customer. Do you know about the ultrasonic cleaning machineCleaning principleWhat is it?

I want to knowThe principle of ultrasonic cleaning machineFirstly, we need to learn a word, which is“Cavitation effect'That's right, the cavitation effect is closely related to the principle of ultrasonic cleaning machines. When the ultrasonic cleaning machine works and emits sufficient ultrasonic energy from the liquid, the vibration of ultrasonic frequency is added to the cleaning liquid, and the interior of the liquid will be utilized and compressed. When the liquid is utilized, bubbles will be generated, and when the liquid is compressed, the bubbles will be compressed, crushed and broken. This is where the famous“Ultrasonic cavitation effect'In fact, the principle of ultrasonic cleaning is to achieve the effect of oil and dirt removal through cavitation effect.

On an overall level, the working principle of an ultrasonic cleaning machine is that the ultrasonic generator emits high-frequency oscillation signals, which are then converted into high-frequency mechanical oscillations by a transducer and propagated into the cleaning solution, causing the liquid to flow and generate a large number of bubbles. These bubbles will cover the surface of the cleaning object, surrounding it layer by layer. Finally, after reaching a certain level of air pressure, the bubbles will burst and gradually remove the stains on the surface of the object.

How exaggerated is the peeling effect of water molecule explosion on stains on workpieces?This depends on the frequency of the ultrasonic transducer, usually even a small, eyeglass washing ultrasonic cleaning machine can reach a speed of every second20000More than once. Although this“explosion'The degree may sound exaggerated, but it is a subtle occurrence, so there is no need to worry about damaging any object.

Now we finally understand the working principle of ultrasonic cleaning machine. It turns out that it is very different from the principle we imagined before. It does not rely on vibration for cleaning. If someone still thinks that the cleaning principle of ultrasonic cleaning machine relies on vibration to take away pollutants, then you are completely wrong!
