28khz Ultrasonic Pulse Cleaning Machine Bath 2000W For Clean Industrial Bearings/Hardware/Metal Parts

The ultrasonic wave propagates 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 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.

Technical characteristics of ultrasonic cleaning machine cleaning:
The cleaning effect is good, the cleanliness is high, and the cleanliness of all the workpieces is consistent. The cleaning speed is fast, the production efficiency is improved, the cleaning liquid does not need to be touched by human hands, and it is safe and reliable. Deep holes, crevices and hidden parts of the workpiece can also be cleaned. No damage to the surface of the workpiece, saving solvent, heat, working space and labor.
Ultrasonic cleaning methods are more than conventional cleaning methods, especially the surface of the workpiece is more complicated, such as some mechanical parts with uneven surfaces, blind holes, and some products that are particularly small and have high requirements for cleanliness, such as: clocks and watches. Ultrasonic cleaning can achieve ideal results for precision mechanical parts, electronic components, circuit board components, etc.
The mechanism of ultrasonic cleaning mainly has the following aspects: due to the strong shock wave generated when the cavitation bubble bursts, a part of the dirt layer is peeled off, dispersed, emulsified, and peeled off under the action of the shock wave.
Because of the bubbles generated by the cavitation phenomenon, the gaps and voids between the dirt layer and the surface layer formed by the impact penetrate. Due to the simultaneous expansion and contraction of such small bubbles and sound pressure, the physical force like peeling repeatedly acts on the dirt layer, and the dirt Layer by layer is peeled off, and the bubbles continue to penetrate inward until the dirt layer is completely peeled off. This is the secondary effect of cavitation. The impact of ultrasonic vibration of cleaning fluid on dirt in ultrasonic cleaning. Ultrasound accelerates the process of dissolving dirt by chemical cleaning agents, and the combination of chemical and physical forces accelerates the cleaning process.

Uses of ultrasonic cleaning machine:
1. Aerospace and aviation-cleaning precision parts. Electronic circuit boards, aircraft wheels, brake systems, air-conditioning heat exchangers, bearings, various metal parts.
2. Railway-various gate valves, brake valves, shock absorbers, bearing kits, condensers, radiators for refrigeration systems of passenger cars and refrigerated cars, locomotive internal combustion engine parts and components, electrical parts and components.
3. Automobile and motorcycle manufacturing industry-cylinder block, cover, steering mechanism, shock absorber and various machined parts, chassis, wheel hub electrophoresis before degreasing, derusting and descaling.
4. Liquid crystal (LCD) manufacturing--cleaning the LCD substrate before plating ITO film, etching the LCD substrate, and cleaning before and after filling the liquid crystal.
5. Optical components-camera lens, microscope, telescope, glasses, watch glass, optical lens after grinding, cleaning before coating.
6. Containers--all kinds of oral liquid containers, food glass and metal containers, cosmetic containers, packaging containers, dental appliance cleaning, inspection panels.
7. Medical appliances-endoscopes, surgical instruments, syringes, test tubes, biochemical test containers, blood, tissue fluid, and dirt cleaning on glass slides.
8. Extraction of effective ingredients of Chinese medicinal materials-replacing the traditional high-temperature water boiling extraction process, which is efficient and protects the effective ingredients.
9. Electronics manufacturing, communications, computers-SMT patch, soldering flux and impurities cleaning after PCB board soldering.
10. Microelectronics-single crystal silicon wafer, integrated circuit manufacturing process cleaning.
