Introduction to the principle of ultrasonic cleaning machine

Before we understand the principle of ultrasonic cleaning machine, let us first understand what is ultrasonic?

Waves can be divided into three types, namely, infrasound, sound waves, and ultrasonic waves. The frequency of the infrasound wave is below 20 Hz ; the frequency of the acoustic wave is 20 Hz to 20 kHz ; and the frequency of the ultrasonic wave is above 20 kHz . The secondary sound waves and ultrasonic waves are generally inaudible to the human ear. Due to the high frequency and short wavelength, the ultrasonic wave has good directionality and strong penetrating power, which is why the ultrasonic cleaning machine is designed and manufactured.

What is the specific principle of the ultrasonic cleaning machine?

The ultrasonic cleaning machine is a high-frequency oscillating signal emitted by the ultrasonic generator, which is converted into a high-frequency mechanical oscillation by the transducer and propagated to the medium. The ultrasonic wave in the cleaning solvent is radiated forward in the cleaning liquid to make the liquid flow. Produces tens of thousands of tiny bubbles, tiny bubbles (cavitating nuclei) present in the liquid vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles grow rapidly, then suddenly close, and the shock wave is generated when the bubble is closed. Thousands of atmospheric pressure are generated around it, destroying insoluble dirt and dispersing them in the cleaning liquid. When the group particles are coated with oil and adhered to the surface of the cleaning member, the oil is emulsified, and the solid particles are detached. Achieve the purpose of cleaning the surface of the cleaning parts. Due to the inherent penetrating power of the ultrasonic wave, it is possible to clean various complex and shape-specific objects, which have a good cleaning effect on small holes and slits, and the best cleaning effect on objects that do not absorb sound or have a small sound absorption coefficient.

Do you know any advantages of ultrasonic cleaners compared to other cleaners?

The ultrasonic cleaning machine has a fast cleaning speed and improves production efficiency.

It is safe and reliable without the need to touch the cleaning solution by hand.

Save solvent, heat, work space and labor.

Deep holes, slits and hidden parts of the workpiece can also be cleaned.

The cleaning effect is good, the cleanliness is high and the cleanliness of all the workpieces is consistent.
