The principle of ultrasonic cleaning machine structure
Ultrasonic cleaning machine structure principle by the ultrasonic generator issued by the high-frequency oscillation signal, through the transducer into high-frequency mechanical oscillation and spread to the medium – cleaning solvent, ultrasound in the cleaning liquid sparse and dense forward radiation, so that the liquid flow and produce tens of thousands of tiny bubbles of 50-500μm diameter, the existence of In the liquid of the tiny bubbles in the role of the acoustic field vibration. These bubbles in the ultrasonic longitudinal propagation of the negative pressure zone formation, growth, and in the positive pressure zone, when the sound pressure reaches a certain value, the bubble rapidly increased, and then suddenly closed. And in the bubble closed when the shock wave, in its surroundings to produce thousands of atmospheric pressure, destroy insoluble dirt and make them scattered in the cleaning fluid, when the group particles are wrapped in oil and adhering to the surface of the cleaning parts, oil is emulsified, solid particles and separated, so as to achieve the purpose of cleaning parts purification. In this process, which is called “cavitation” effect, the bubble closure can form a few hundred degrees of high temperature and more than 1000 air pressure instant high pressure.Suggest you have a look granboultrasonic cleaner, It can be applied to medical equipment.
Advantages of the ultrasonic cleaning machine structure
The advantages of the ultrasonic cleaning machine structure are: good ultrasonic cleaning effect and simple operation. The sound people hear is the frequency of 20-20000Hz sound wave signal, higher than 20000Hz sound waves called ultrasonic, the transmission of sound waves in accordance with the sine curve longitudinal propagation, producing a large number of small bubbles . One reason is the local tensile stress in the liquid and the formation of negative pressure, the reduction in pressure so that the original dissolved in the liquid gas oversaturation, and escape from the liquid, becoming a small bubble; another reason is the strong tensile stress of the liquid “torn open” into a hole, known as cavitation.
