The research shows: the ultrasonic effect on the liquid, rupture of each bubble in liquid will produce great shock wave energy, equivalent to several hundred degrees and instantly generate high temperature up to thousands of atmospheres, this phenomenon is called "cavitation", ultrasonic cleaning is the shock waves generated by the liquid bubble rupture to wash and scour workpieces inner surface and the outer surface of the role. Ultrasonic wave propagation in a liquid, the liquid from the cleaning tank at ultrasonic frequencies with the vibration, liquid and cleaning tank vibration has its own natural frequency, the vibration frequency is the frequency, so people can hear the hum.

Fully automatic ultrasonic cleaning machine working principle

Fully automatic ultrasonic cleaning machine is mainly the principle of transducer, the ultrasonic power source energy, and converted to mechanical vibration, the cleaning tank wall will make the cleaning liquid in the channel to ultrasonic radiation. The ultrasonic radiation, micro bubble liquid so that the groove in the can in the acoustic waves so as to keep the vibration. When the pressure or sound intensity under pressure reaches a certain degree of time, will be the rapid expansion of bubbles, and then suddenly closed. In this process, the bubble is closed instantly produce shock waves, the bubble is generated around the 1012-1013pa pressure and temperature pressure of this bureau, huge ultrasonic cavitation generated can destroy the insoluble dirt and make their differentiation in solution, vapor cavitation dirt directly repeated impact. A damage absorption dirt and cleaning surface, on the other hand can cause fatigue damage layer of dirt is stripping, vibration gas type bubble scrub on the solid surface, pollution layer once seam drill, bubble immediately "get" vibrations cause the pollution layer off, because the air into use, two kinds of liquid in the interface quickly dispersed and emulsified oil, when the solid particles are wrapped and adhesion in the surface of the cleaning piece, oil is emulsified, solid particle off on their own, the ultrasound propagation in the wash liquid will produce positive and negative alternating pressure, jet formation, impact cleaning parts, at the same time, because of the nonlinear effect will generate acoustic streaming and microphone flow, 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 boundary pollution layer, increasing the stirring, diffusion effect, accelerate the dissolution of soluble pollutants, strengthening cleaning effect of chemical cleaning agent. Thus, any liquid can be dipped and sound field place there are cleaning, cleaning the characteristics apply very complex on the surface shape of the parts. Especially the use of this technology, can reduce the dosage of chemical solvent, thereby greatly reducing the pollution of the environment

Composition of automatic ultrasonic cleaning machine

The whole process fully automatic ultrasonic cleaning machine for automatic. (the use of mechanical hand single beam multiarm). Full automatic ultrasonic cleaning machine is mainly composed of two parts of the ultrasonic cleaning tank and ultrasonic generator. Made of ultrasonic cleaning tank with sturdy good elasticity, corrosion resistance of high quality stainless steel, are arranged at the bottom of the vibrator of the ultrasonic transducer; ultrasonic generator to generate high voltage and high frequency, through the cable connection line conduction to the transducer, the transducer and the vibration plate together to generate a high frequency resonance, so that the cleaning tank by solvents of dirt by the action of the ultrasonic cleaning.
