Working Principle Of Ultrasonic Equipment

The principle of the automatic ultrasonic cleaning machine is mainly to convert the sound energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and radiate the cleaning liquid in the tank to ultrasonic waves through the cleaning tank wall. Due to the radiated ultrasonic waves, the microbubbles in the liquid in the tank can maintain vibration under the action of sound waves. When the sound pressure or sound intensity reaches a certain level, the bubble will expand rapidly and then suddenly close. During this process, the shock wave is generated at the moment when the bubble is closed, causing a pressure of 1012-1013pa and local temperature adjustment around the bubble. The huge pressure generated by this ultrasonic cavitation can destroy insoluble dirt and make them differentiate in the solution. The direct and repeated impact of steam-type cavitation on dirt. On the one hand, it destroys the adsorption of the dirt and the surface of the cleaning part, and on the other hand, it can cause the fatigue damage of the dirt layer and be dismissed. The vibration of the gas bubble scrubs the solid surface. Once the dirt layer is cracked, the bubbles are immediately " The “drilling” vibration causes the dirt layer to fall off. Due to cavitation, the two liquids are rapidly dispersed and emulsified at the interface. When the solid particles are wrapped in oil and adhere to the surface of the cleaning part, the oil is emulsified and the solid particles fall off by themselves. When it propagates in the cleaning liquid, it will produce positive and negative alternating sound pressure, forming a jet, which impacts the cleaning part. At the same time, due to the nonlinear effect, it will produce acoustic and micro-acoustic flow. Ultrasonic cavitation will produce high-speed at the solid-liquid interface. Microjets, all of these effects, can destroy dirt, remove or weaken the boundary dirt layer, increase stirring and diffusion, accelerate the dissolution of soluble dirt, and strengthen the cleaning effect of chemical cleaning agents. It can be seen that any place where the liquid can be immersed and the sound field has a cleaning effect, and its characteristics are suitable for cleaning parts with very complicated surface shapes. Especially after using this technology, the amount of chemical solvents can be reduced, thereby greatly reducing environmental pollution
