The frequently questions and working principles of ultrasonic cleaners?
Ultrasonic cleaners are instruments used to remove contaminants. The transducers clean the items by converting the ultrasonic energy of the ultrasonic source into mechanical vibration, which is widely used in industry, defense, and biomedical fields.
Studies have shown that when ultrasonic waves are applied to a liquid, the rupture of each bubble in the liquid generates a shock wave with a very large energy, which is equivalent to instantaneously generating several hundred degrees of high temperature and up to thousands of atmospheric pressures. This phenomenon is called “empty”. "Chemical action", ultrasonic cleaning is the use of the shock wave generated by the collapse of bubbles in the liquid to achieve the role of cleaning and flushing the inner and outer surfaces of the workpiece. The ultrasonic wave propagates in the liquid, causing the liquid and the cleaning tank to vibrate together at Ultrasonic Handheld spot Welder 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 hum.
Ultrasonic cleaners remove contaminants from liquids and solids on the work surface to achieve a certain level of cleanliness. Cleaning is a very complex physical and chemical process.
Cleaning is not only related to the nature, type, morphology and degree of adhesion of the contaminants, but also related to the physical and chemical properties of the cleaning medium, the cleaning performance, the material of the workpiece, and the state of the surface; the ultrasonic cleaner is scientifically reasonable according to the cleaning conditions. Cleaning process.
The whole process of automatic ultrasonic cleaning machine is fully automatic. (Using a single-beam multi-arm robot). Ultrasonic automatic cleaning machine is mainly composed of two parts: ultrasonic cleaning tank and ultrasonic generator. The ultrasonic cleaning tank is made of high-quality stainless steel with good elasticity and corrosion resistance. The ultrasonic transducer vibrator is installed at the bottom; the ultrasonic generator generates high-frequency and high-voltage and is transmitted to the transducer through the cable connecting line. The transducer and the vibrating plate are together The high-frequency resonance is generated so that the solvent in the cleaning tank is subjected to the ultrasonic cleaning of the dirt.
In all cleaning methods, multi-hook synchronous automatic ultrasonic cleaning is the most efficient and effective one. The reason why ultrasonic cleaning can achieve such an effect is closely related to its unique working principle and cleaning method. We know that in production and life, there are many things that need cleaning, and there are many kinds and links that need to be cleaned. For example, the removal of pollutants from objects, the clearing of small holes, and the common manual cleaning methods are undoubtedly impossible for concealed objects and objects. To meet the requirements, even steam cleaning and high-pressure water jet cleaning cannot meet the demand for high cleanliness. Ultrasonic cleaning can also kill bacteria, dissolve organic pollutants, prevent over-corrosion, etc., so ultrasonic cleaning is increasingly Widely used in all walks of life: (1) Machinery industry: removal of rust-proof grease; cleaning of measuring tools; degreasing of mechanical parts and rust; cleaning of engines, carburetors and automobile parts; cleaning of filters, filters, etc. . (2) Surface treatment industry: degreasing and rust removal before plating; cleaning before ion plating; phosphating; removing coke; removing oxide scale; removing polishing paste; surface activation treatment of metal workpieces, etc. (3) Instrumentation industry: High-precision cleaning of precision parts before assembly. (4) Electronic industry: Printed circuit boards except for rosin, welding spot; cleaning of high-voltage contacts and other mechanical and electronic parts. (5) Medical industry: Cleaning, disinfection, sterilization of medical devices, and cleaning of experimental utensils. (6) Semiconductor industry: High cleanliness cleaning of semiconductor wafers. (7) Watch and watch industry, decoration industry: remove sludge, dust, oxide layer, polishing paste and so on. (8) Chemical and biological industries: cleaning and descaling of experimental utensils. (9) Optical industry: Degreasing, de-sweating and cleaning of optical devices.
