Why ultrasonic cleaners can clean dirt

The descaling equipment of Ultra Sonic Cleaner is mainly composed of ultrasonic generator, ultrasonic vibration plate, cleaning tank, etc. Ultrasonic descaling mainly uses ultrasonic power supply to generate ultrasonic energy on the corresponding ultrasonic vibrator in the liquid through cavitation and physical action. Under the action of ultrasonic waves, the fouling substances are dispersed, loosened, broken, destroyed, and fallen off, and are not easily attached to the pipe wall, thus achieving the effect of ultrasonic descaling. The principle of ultrasonic descaling is mainly in the following aspects:
1. Cavitation effect
The energy of the ultrasonic wave directly produces a large number of cavities and bubbles on the fluid medium to be processed. When the sound pressure or sound intensity reaches a certain level, the bubbles will expand rapidly and then close suddenly. The pressure peak can reach thousands of atmospheres. Under the action of the pressure peak, the scale-forming substances are broken and destroyed and suspended in the water, and the natural scale layer is broken and easy to fall off, so as to achieve the purpose of ultrasonic descaling.
2. Shearing effect
Ultrasonic radiation is radiated on the scale layer, the tube wall and the water. Because of the different frequency responses to the ultrasonic waves, the three produce asynchronous vibrations, resulting in high-speed relative motion. Because of the speed difference, the interface between the scale layer and the heat exchanger tube wall is formed. The relative shear force will cause the scale layer to be tired and loose, so as to achieve the purpose of ultrasonic descaling.
3. Repression effect
By changing the physical and chemical properties of the fluid body through the action of ultrasonic waves, the nucleation and growth of ions in the water can be suppressed. Therefore, the number of scaling ions adhering to the surface of the heat exchanger can be reduced. Practical studies have confirmed that the ultrasonic action time The longer it is, the better the effect of preventing scaling substances from scaling.
​​
Under the action of ultrasonic cleaning machine, when the ultrasonic energy is large enough, that is, "power ultrasonic" can cause short "cavitation" in the conductive medium under the premise of normal temperature and normal pressure, which will cause many mechanical and physical problems. , chemical, biological and other effects, to achieve the purpose of ultrasonic descaling of cleaning objects in fluids.
