Ultrasonic cleaning machine – working principle

With the continuous progress of science and technology, ultrasonic cleaners are gradually known by people. Because of their obvious cleaning effect and simple operation, ultrasonic cleaners are gradually popularized in various industries. Ultrasonic cleaning machine has been seen everywhere in our life. Maybe many people know how to control it, but how many people know the principle of ultrasonic cleaning machine?

Ultrasonic cleaning machine power frequency selection

Principle of ultrasonic cleaning machine – ultrasonic  

To know the principle of ultrasonic cleaning machine, we must first know what is ultrasonic. Ultrasonic wave is the sound wave with a frequency higher than 20000 Hz, which can be divided into power ultrasonic wave and detection ultrasonic wave in practical application. It has good directivity, strong penetrability, and is easy to obtain concentrated sound energy. It spreads far in dense solids and liquids, and can be used for ranging, industrial flaw detection, medical B-ultrasound, cleaning, welding, drilling, gravel, sterilization, etc.

Ultrasonic Cleaner Applications

Principle Analysis of Ultrasonic Cleaning Machine

The ultrasonic wave propagates in the liquid, making the liquid and the cleaning tank vibrate together at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequency. This vibration frequency is the acoustic frequency, so people can hear the buzz. With the continuous development of the cleaning industry, more and more industries and enterprises have applied ultrasonic cleaning machines.

Cleaning machine technical characteristics

The principle of the ultrasonic cleaning machine is that the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation through the transducer and transmitted to the medium cleaning solvent. The forward radiation of the ultrasonic wave in the cleaning solution makes the liquid flow and generate tens of thousands of straight diameters of 50-500 μ M, the tiny bubbles in liquid vibrate under the action of sound field. These bubbles form and grow in the negative pressure area of ultrasonic longitudinal propagation, while in the positive pressure area, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. The shock wave will be generated when the bubble is closed, and thousands of atmospheres will be generated around the bubble to destroy the insoluble dirt and make them disperse in the cleaning solution. When the group particles are wrapped in oil and adhere to the surface of the cleaning part, the oil will be emulsified, and the solid particles will be separated, so as to achieve the purpose of cleaning parts purification. In the process of this so-called “cavitation” effect, bubble closure can form a high temperature of several Baidu and an instantaneous high pressure of more than 1000 air pressures.

The ultrasonic cleaning machine has indeed brought a lot of convenience to our life, but pregnant women and children must not operate the ultrasonic cleaning machine. Although there is no radiation from ultrasound, the sound generated during the operation of the ultrasonic cleaning machine still has an impact on pregnant women. Even the workers who are specialized in ultrasonic cleaning machines cannot operate them without rest for a long time.
