Ultrasonic cleaner is an instrument used to remove pollutants. It converts the sound energy of power ultrasonic frequency source into mechanical vibration to clean articles through transducer.
Ultrasonic cleaner is an instrument used to remove pollutants. It converts the sound energy of power ultrasonic frequency source into mechanical vibration to clean articles through transducer. It is widely used in industry, national defense, biomedicine and other aspects.
Introduce
Research has proved that: ultrasonic wave ACTS on liquid, each bubble burst in the liquid will produce enormous shock wave energy, equivalent to a few baidu's high temperature and instantaneous generation up to thousands of atmospheric pressure, this phenomenon is known as "cavitation effect", ultrasonic cleaning is used in the liquid shock wave produced by bubbles burst to purge and flush effect on the surface of the workpiece inside and outside. Ultrasonic waves travel through the liquid, making the liquid and the cleaning tank vibrate together at ultrasonic frequencies. The liquid and the cleaning tank vibrate at their own natural frequencies. This vibration frequency is the frequency of sound waves, so people hear a buzz.
Ultrasonic cleaner is to remove the liquid and solid pollutants on the working surface, so as to achieve a certain degree of cleanliness. Cleaning is a complex physical and chemical process.
Cleaning is not only related to the nature, type, form and degree of adhesion of pollutants, but also related to the physical and chemical properties of the cleaning medium, cleaning performance, material and surface state of the workpiece. Ultrasonic cleaner is a scientific and reasonable cleaning process according to the cleaning conditions.
The working principle of
The principle of the automatic ultrasonic cleaning machine is to convert the transducer, the power of the ultrasonic energy of the ultrasonic source, and to mechanical vibration, through cleaning the tank wall so that the cleaning liquid in the tank will be radiated to the ultrasonic wave. Because of the ultrasonic radiation, the tiny bubbles in the liquid in the tank are kept vibrating by the sound waves. When the pressure of sound pressure or sound intensity reaches a certain level, the bubble expands rapidly and then suddenly closes again. During this process, a shock wave is generated at the moment when the bubble closes, causing 1012-1013pa of pressure and local temperature regulation around the bubble. The huge pressure generated by this ultrasonic cavitation can destroy the insoluble dirt and make them differentiate in the solution. The direct and repeated impact of steam cavitation on the dirt. On the one hand, destroy the adsorption on the surface of the dirt and clean, on the other hand can cause dirt layer by barge from fatigue damage, the vibration of the gas type bubble to scrub of solid surface, once the fouling layer seam drilling, bubble "into" vibration make the fouling layer falls off, immediately due to cavitation, quick dispersion and emulsification, two liquids in the interface when the solid particles is smeary wrapped and on the surface of the adhesive in cleaning, oil was emulsified and solid particles to fall off, ultrasonic propagation in the cleaning fluid will produce positive and negative alternating pressure, jet formation, the impact cleaning parts, at the same time due to nonlinear effects will produce acoustic streaming and acoustic streaming, Ultrasonic cavitation, on the other hand, produces a high-speed micro-jet at the interface between solid and liquid. All these effects can destroy dirt, remove or weaken boundary dirt layers, increase stirring and diffusion, accelerate the dissolution of soluble dirt, and enhance the cleaning effect of chemical cleaning agents. It can be seen that any place where liquid can be immersed and the sound field exists has a cleaning function, and its characteristics are suitable for the cleaning of parts with very complex surface shapes. In particular, the use of this technology can reduce the amount of chemical solvents, thus greatly reducing environmental pollution.
