The principle of the ultrasonic cleaning device is to use the transducer to test the sound energy of the powerful ultrasonic frequency source.
It has been proved through research that when the if a Ultrasonic wave acts on the liquid, the liquid will be destroyed. The bursting of each bubble in the liquid creates a shock wave of great energy, equivalent to the instantaneous generation of a high temperature of several hundred degrees and a pressure of up to thousands of atmospheres. This phenomenon is called “cavitation”. The shock wave generated by the fracture can achieve the effect of cleaning and cleaning the inner and outer surfaces of the workpiece.
Ultrasound propagates through the liquid, causing the liquid and cleaning tank to vibrate in unison at the ultrasonic frequency. When the liquid and cleaning tank vibrate, they have their own natural frequency. This vibration Ffrequency is the sound wave frequency, so people just heard the buzz.
The principle of the automatic ultrasonic cleaning machine is mainly to convert the transducer into the sound energy of the powerful ultrasonic frequency source and it converts it into mechanical vibration and emits the cleaning liquid in the tank through the wall of the cleaning tank in ultrasonic waves.
Due to the ultrasonic waves radiated, the micro-bubbles in the liquid in the tank can keep the vibration under the action of sound waves. When the sound pressure or intensity reaches a certain pressure level, the bubble expands rapidly and then suddenly closes.
During this process, at the moment the bubbles close, shock waves are generated, causing a pressure of 1012-1013 Pa and local temperature regulation around the bubblescauses. The enormous pressure generated by this ultrasonic cavitation can destroy. The insoluble soil will cause it to decompose in solution and through the direct and repeated exposure of the soil to steam cavitation.
On the one hand, it destroys the adsorption between the dirt and the surface of the cleaning piece, on the other hand, the layer of dirt can suffer fatigue damage and be worn away. The vibration of the gas bubbles scrubs the solid surface. As soon as the layer of dirt shows cracks for drilling, the air bubbles immediately drill into it and vibrate, causing the layer of dirt to fall off;
Due to the effect of cavitation, the two liquids quickly disperse and emulsify on the surface interface. When the oil is enveloped and sticks to the surface of the cleaning parts, the oil will be emulsified and the solid particles will fall off by themselves. When the ultrasonic wave propagates in the Reiniliquid, generates positive and negative alternating sound pressures, forms jets and acts on the cleaning parts. At the same time, acoustic flow is created due to non-linear effects, micro-acoustic flow is generated, and high-speed micro-jet flow is generated at the solid-liquid interface by ultrasonic cavitation. All of these effects can destroy filth and remove or weaken border pollution. Increase layering, agitation and diffusion, accelerate dissolving of soluble dirt and enhance the cleaning effect of chemical cleaning agents.
It can be seen that any place where the liquid can be immersed and the sound field is present has a cleaning effect and its properties are suitable for cleaning parts with very complicated surface shapes. In particular, the introduction of this technology can reduce the amount of chemical solventsen, thereby significantly reducing environmental pollution
The whole process of automatic ultrasonic cleaning machine for the machineCompletely automatic. (Using a single-beam multi-arm manipulator). The automatic ultrasonic cleaning machine mainly consists of two parts: an ultrasonic cleaning tank and an ultrasonic generator.
The ultrasonic cleaning tank is made of high-quality stainless steel, with elasticity and good corrosion resistance, and an ultrasonic transducer vibrator is installed at the bottom;
< br/> Ultrasonic generator There will be High frequency and high voltage are generated, which are transmitted to the transducer through the cable connection line, and the transducer and the vibrating plate together generate high-frequency resonance, so that the solvent in the cleaning tank is subjected to ultrasonic waves to remove the dirt.
