Ultrasonic Cleaner
Jan 12, 2019

Ultrasonic waves propagate in the liquid, causing the liquid to vibrate together with the cleaning tank at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequencies. This vibration frequency is the acoustic frequency, so people hear the humming sound. With the continuous development of the cleaning industry, more and more industries and enterprises have applied ultrasonic cleaning machines.

The high-frequency oscillating signal emitted by the ultrasonic generator on the principle of the ultrasonic cleaning machine is converted into a high-frequency mechanical oscillation by the transducer and propagated into the medium--cleaning solvent, and the ultrasonic waves are radiated in the cleaning liquid in a dense manner. The liquid flows to generate tens of thousands of tiny bubbles having a diameter of 50-500 μm, 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 region in which the ultrasonic waves propagate longitudinally, and in the positive pressure region, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. And when the bubble is closed, a shock wave is generated, thousands of atmospheric pressures are generated around it, and the insoluble dirt is destroyed to disperse them in the cleaning liquid. When the group particles are wrapped by the oil and adhere to the surface of the cleaning member, the oil is emulsified, and the solid is solid. Particles and detachment, so as to achieve the purpose of cleaning the cleaning parts. In this process known as the "cavitation" effect, the bubble closure can form a high temperature of several hundred degrees and an instantaneous high pressure of more than 1000 atmospheres.

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 the acoustic signal with a frequency of 20-20000 Hz. The sound wave higher than 20000 Hz is called ultrasonic wave, and the transmission of sound wave propagates longitudinally according to the sinusoidal curve, generating a large number of small bubbles. One reason is that a tensile stress is locally generated in the liquid to form a negative pressure. The decrease in pressure causes the gas originally dissolved in the liquid to be supersaturated, and escapes from the liquid to become small bubbles; another reason is that the strong tensile stress tears the liquid apart. "Become a hollow, called cavitation.

The ultrasonic cleaner we are making divide into two types, one is the desktop cleaner, the other type is the industrial ultrasonic cleaner. Industrial cleaner is customized, OEM and ODM all acceptable!
