Ultrasonic Cleaning Machine
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.
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 between the dense and dense phases in the cleaning liquid. The flow of the liquid produces tens of thousands of tiny bubbles with a diameter of 50-500μm. The tiny bubbles 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 "cavitation" effect, the closed bubble can form a high temperature of several hundred degrees and an instantaneous high pressure of more than 1000 atmospheric pressure.
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 higher than 20000 Hz is called ultrasonic. 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 in the liquid forms 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.
Application field
Ultrasonic cleaners are widely used in surface spray treatment industry, machinery industry, electronics industry, medical industry, semiconductor industry, watch jewelry industry, optical industry, textile printing and dyeing industry. For other industries, the application of ultrasonic cleaning machine is as follows
1. Surface spraying treatment industry: (Cleaning attachments: oil, mechanical chips, abrasives, dust, polishing wax) before electroplating, removing carbon deposits, removing oxide scales, removing polishing paste, removing oil and rust, cleaning before ion plating, Phosphating treatment, surface activation treatment of metal workpieces, etc. Stainless steel polished products, stainless steel knives, tableware, knives, locks, lighting, hand decorations before spraying, cleaning before electroplating.
2. Machinery industry: (Cleaning attachments: cutting oil, abrasive particles, iron filings, dust, fingerprints)
Removal of anti-rust grease; cleaning of measuring tools; degreasing and rust removal of mechanical parts; engines, engine parts, gearboxes, shock absorbers, bearings, oil nozzles, cylinder blocks, valve bodies, carburetors and automotive parts and chassis paint Degreasing, rust removal, cleaning before phosphating; dredging and cleaning of filters, piston fittings, filter screens, etc. Precision machinery parts, compressor parts, camera parts, bearings, hardware parts, molds, especially in the railway industry, are very suitable for the degreasing and decontamination of air conditioners in train cars, and the rust prevention, derusting and degreasing of various parts of the train head.
