What are the principles of ultrasonic cleaning machine

2021-11-11 07:57:09

        The cleaning principle of the ultrasonic cleaning machine is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium---the cleaning solvent, and the ultrasonic waves are radiated forward in the cleaning solution. , make the liquid flow to generate tens of thousands of tiny bubbles with a diameter of 50-500μm, and the tiny bubbles existing in the liquid vibrate under the action of the sound field. These bubbles form and grow in the negative pressure area where ultrasonic waves propagate longitudinally, while in the positive pressure area, when the sound pressure reaches a certain value, the bubbles rapidly increase and then close suddenly. And when the bubble is closed, a shock wave is generated, and thousands of atmospheres are generated around it, which destroys the insoluble dirt and makes them dispersed in the cleaning liquid. Particles and detachment, so as to achieve the purpose of cleaning parts.

What are the principles of ultrasonic cleaning machine

  In this process called "cavitation" effect, the closing of the bubble can form a high temperature of hundreds of degrees and an instantaneous high pressure of more than 1000 air pressure, and the instantaneous high pressure is continuously generated like a series of small "explosions" constantly impacting objects The surface of the object and the dirt in the gap can be quickly peeled off, so as to achieve the purpose of cleaning and purifying the surface of the object.

  The second ultrasonic wave propagates in the liquid, so that 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 frequency of the sound wave, so people hear the buzzing sound.

  In addition, in the ultrasonic cleaning process, the bubbles visible to the naked eye are not vacuum nucleus group bubbles, but air bubbles, which inhibit cavitation and reduce cleaning efficiency. Only when the air bubbles in the liquid are completely dragged away, the cavitation vacuum nucleus group bubbles can achieve good results.
