Principle of Ultrasonic Cleaner
Ultrasonic cleaning machine is a high-frequency oscillation signal sent by an ultrasonic generator, which is converted into high-frequency mechanical oscillation by a transducer (vibrator) and propagated to the medium-the cleaning solvent. The ultrasonic wave radiates forward in the cleaning solution. , Make the liquid flow to produce 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 zone where the ultrasonic wave propagates longitudinally. In the positive pressure zone, when the sound pressure reaches a certain value, the bubbles increase rapidly and then suddenly close. And when the bubble is closed, a shock wave is generated, and thousands of atmospheres are generated around it, destroying insoluble dirt and dispersing them in the cleaning liquid. When the group particles are wrapped in oil and adhere to the surface of the cleaning part, the oil is emulsified and solid Particles and separation, so as to achieve the purpose of cleaning parts purification. In this process called the "cavitation" effect, the closed bubble can form a high temperature of several hundred degrees and an instantaneous high pressure of more than 1,000 atmospheric pressures. The continuous generation of instantaneous high pressure is like a series of small "explosions" continuously impacting objects. Surface, so that 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.
