Solid performance. 4 "Medical Forest Ministries": Jianshui water, diarrhea evil, go to the disease. 5 "Meeting Medical Mirror": Only remnant Lek, hematuria, reduce it. 6 "Bencao Qiu Yuan": cure lungs, kidney cold, urine, wills, eyesight, long muscles. Also cure liver and kidney wind poison attack. Ultrasonic waves propagate in the liquid, causing the liquid and the cleaning tank to 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 sound wave frequency, so people hear the buzzing sound. With the continuous development of the cleaning industry, more and more industries and enterprises have used ultrasonic cleaning machines.
The advantages of the ultrasonic cleaning machine are: the ultrasonic cleaning effect is good, and the operation is simple. The sound that people hear is a sound wave signal with a frequency of 20-20000 Hz. The sound wave above 20000 Hz is called an ultrasonic wave. The transmission of the sound wave propagates longitudinally according to a sinusoidal curve, producing a large number of small bubbles. One reason is that partial tensile stress occurs in the liquid to form negative pressure. The decrease in pressure makes the gas originally dissolved in the liquid supersaturate and escape from the liquid and become small bubbles; the other reason is that the strong tensile stress tears the liquid apart. "A void is called cavitation.

For the principle of ultrasonic cleaning machine, the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium-the cleaning solvent. The ultrasonic wave radiates forward in the dense and dense phases in the cleaning liquid. The flow of liquid produces 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 detachment, so as to achieve the purpose of cleaning parts purification. In this process known as 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 atmospheres.
