What is the working principle of an ultrasonic cleaner?
Because of the ultrasonic radiation, the micro bubbles in the liquid in the tank can vibrate under the action of sound waves. When the sound pressure or sound intensity is reached by a certain degree of pressure, the bubble will expand rapidly and then suddenly closed
Ultrasonic propagation in cleaning liquid will produce positive and negative alternating pressure, jet formation, impact cleaning, and because the nonlinear effect will produce acoustic streaming and micro acoustic streaming, and ultrasonic cavitation will produce high-speed micro jets in the solid and liquid interface, all these effects can destroy the dirt, remove or weaken the pollution boundary layer to increase the mixing and diffusion effect, accelerate the dissolution of soluble pollutants, strengthen the cleaning effect of chemical cleaning agent
On the one hand and destroy the dirt cleaning a surface, on the other hand can cause fatigue damage and dirt layer was transferred from the gas bubble type, vibration scrubbing on solid surface pollution layer once the seam can be drilled, bubble immediately drill down vibration causes the pollution layer off, because the air into use, two kinds of liquid in the interface rapidly dispersed and emulsified oil, when the solid particles wrapped and adhered to the surface cleaning, oil emulsion, solid particles to fall off
In this process, the bubble closing instant shock wave, the bubble generated around the pressure of 1012-1013pa and bureau of regulation, such tremendous pressure produced by ultrasonic cavitation can destroy the insoluble dirt and make their differentiation in solution, the steam type cavitation on the dirt directly repeated impact
The transducer, the power source of the ultrasonic energy, and converted to mechanical vibration, by cleaning groove wall the cleaning fluid in the channel to the ultrasonic radiation
