What is the principle of ultrasonic cleaner? What do you mean ultrasound?

What is the principle of ultrasonic cleaner?
The principle of ultrasonic cleaning machine simply put struck is that ultrasonic cleaning is the shock wave produced by the rupture of bubbles in the liquid to achieve the function of cleaning and flushing the internal and external surfaces of the workpiece Next, China's joint market research network of small editor to give you a detailed talk about the ultrasonic cleaning machine principle is what? What is called ultrasound?
Ultrasonic cleaner principle: the power ultrasonic source of the sound energy into mechanical vibration and through cleaning tank wall to the cleaning fluid radiation ultrasonic, the liquid in the tank under the influence of sound waves vibration, when the sound pressure or sound strength reached a certain value, the bubble rapidly grows, and then suddenly closed, in the bubble closed instantaneous shock wave to create 1012-1013 pa around the pressure and local temperature, The great pressure generated by this ultrasonic cavitation can destroy insoluble dirt and make them differentiate in the solution, steam-type cavitation of the direct repeated impact of dirt, on the one hand, to destroy the surface of the dirt and cleaning parts adsorption, on the other hand can cause fatigue damage of the dirt layer is disallowed, gas-type bubble vibration on the solid surface scrubbing, the layer of dirt can be slit, the bubble immediately "drilled into" the vibration of the layer, the two rapidly dispersed When solid particles are encased in oil and glued to the surface of the cleaning piece, the oil is emulsified, the solid particles fall off on their own, and the ultrasonic ultrasonic propagation in the cleaning fluid produces positive and negative cross-change acoustic pressure, forming a jet stream, impact cleaning parts, and due to nonlinear effects will produce sound flow and micro-flow and micro-flow Sound flow, and ultrasonic cavitation in the solid and liquid interface will produce high-speed micro-jet, all of which can destroy the dirt, remove or weaken the boundary layer, increase stirring, diffusion, accelerate the dissolution of soluble dirt, strengthen the cleaning effect of chemical cleaning agent Thus, where liquid can be immersed and the sound field exists, there is a cleaning effect, its characteristics are suitable for the surface shape of very complex parts cleaning In particular, the use of this technology, can reduce the amount of chemical solvents, thereby greatly reducing environmental pollution
Second, ultrasonic cleaning machine principle of what is called ultrasonic?
Sound waves are one of the categories of sound, belong to mechanical waves, sound waves refer to the human ear can feel a kind of vertical waves, the frequency range of 16hz-20khz When the frequency of a sound wave is below 16hz, it is called a secondary sound wave, and a higher than 20khz is called an ultrasonic sound wave
Ultrasound has the following characteristics: 1) Ultrasonic waves can be effectively transmitted in gases, liquids, solids, solid melts and other media
2) Ultrasound can transmit strong energy
3) Ultrasound produces reflexes, interferences, overlays and resonances
4) When ultrasonic waves travel in a liquid medium, they can produce strong shock and cavitation on the interface
Third, the principle of ultrasonic cleaning machine what is cleaning cleaning refers to the removal of liquid and solid pollutants on the surface of the workpiece, so that the workpiece to achieve a certain degree of cleanliness, cleaning process is cleaning media, pollutants, worksurface surface of the interaction of the three, is a complex physical, chemical process Cleaning is not only related to the nature, type, morphology and degree of adhesion of pollutants, to the physical and chemical properties of the cleaning medium, cleaning functions, materials of workpieces, surface status, but also to cleaning conditions such as temperature, pressure and additional ultrasonic vibration, mechanical external forces and other factors Therefore, the choice of scientific and reasonable cleaning process, must be process analysis Application: This type of model uses municipal water plus a little water-soluble cleaning agent to form a cleaning solution, so the cost of use is low Widely used in hardware, electronics, watches, machinery, tools, glasses, jewelry, semiconductor silicon wafers, polyester spray plate and polyester filter core and glassware cleaning
