Ultrasonic Cleaning Machine

Ultrasonic waves propagate in liquids, causing the liquid and cleaning tank to vibrate together at the ultrasonic frequency. When the liquid and cleaning tank vibrate, they have their own inherent frequency, which is the frequency of sound waves, so people hear buzzing sounds. With the continuous development of the cleaning industry, more and more industries and enterprises are using ultrasonic cleaning machines.
The principle of ultrasonic cleaning machine is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation through a transducer and propagated to the medium - cleaning solvent. The ultrasonic wave radiates forward in the cleaning solution, causing the liquid to flow and produce tens of thousands of diameters ranging from 50 to 500 μ The tiny bubbles of m exist in liquid and vibrate under the action of sound field. These bubbles form and grow in the negative pressure zone where ultrasonic waves propagate longitudinally, while in the positive pressure zone, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. And when the bubble closes, a shock wave is generated, generating thousands of atmospheres around it, destroying insoluble pollutants and dispersing them in the cleaning solution. When group particles are wrapped in oil and adhere to the surface of the cleaning part, the oil is emulsified, and solid particles detach, thereby achieving the purpose of cleaning the cleaning part. In this process known as the "cavitation" effect, bubble closure can form high temperatures of several hundred degrees Celsius and instantaneous high pressures exceeding 1000 atmospheres.
The advantages of ultrasonic cleaning machine are: good ultrasonic cleaning effect and simple operation. The sound that people hear is a sound wave signal with a frequency of 20-20000Hz, and sound waves above 20000Hz are called ultrasonic waves. The transmission of sound waves propagates longitudinally along a sinusoidal curve, producing a large number of small bubbles. One reason is that local tensile stress occurs in the liquid, resulting in negative pressure. The decrease in pressure causes the gas that was originally dissolved in the liquid to supersaturate and escape from the liquid, becoming small bubbles; Another reason is that the strong tensile stress tears the liquid open into a cavity, known as cavitation.
