What is the working principle of the ultrasonic cleaning machine? The following is to introduce the main links and steps of its work, the principle and knowledge of how the ultrasonic cleaner works。 The principle of the ultrasonic cleaning machine is mainly to convert the transducer, the sound energy of the power ultrasonic frequency source, into mechanical vibration, and radiate the cleaning liquid in the tank to the ultrasonic wave by cleaning the tank wall。 Because of the radiated ultrasonic wave, the micro bubbles in the liquid in the tank can keep vibration under the action of acoustic wave。 When the pressure of sound or sound intensity reaches a certain level, the bubbles expand rapidly and then close suddenly。 In this process, shock waves are generated at the instant of bubble closure, resulting in 1012-1013 PA pressure and local temperature regulation around the bubble。 This huge pressure generated by ultrasonic cavitation can destroy insoluble dirt and make them differentiate into solution。 Steam cavitation directly repeats the impact on dirt。
On the one hand, it destroys the adsorption of dirt and cleaning parts, on the other hand, it can cause the fatigue damage of the dirt layer and be rejected. The vibration of gas bubbles scrubs the solid surface. Once the dirt layer is seamless and drillable, the bubbles immediately "drill" into the vibration to make the dirt layer fall off. Because of cavitation, the two liquids disperse rapidly at the interface and emulsify. When the solid particles are bound by oil pollution, they adhere to the surface. Oil is emulsified and solid particles fall off on the surface of cleaning parts. When ultrasound propagates in cleaning solution, it produces positive and negative alternating sound pressure, forms a jet and impacts the cleaning parts. At the same time, because of the non-linear effect, sound flow and micro-sound flow will be generated, while ultrasonic cavitation will produce high-speed micro-jet at the interface of solid and liquid. All these effects can destroy dirt, remove or weaken the boundary. The sewage layer can increase agitation and diffusion, accelerate the dissolution of soluble sewage, and strengthen the cleaning effect of chemical cleaning agent. It can be seen that all the places where the liquid can be immersed and the sound field exists have cleaning effect, and its characteristics are suitable for cleaning parts with very complex surface shape. Especially after using this technology, the amount of chemical solvents can be reduced, thus greatly reducing environmental pollution.
