Ultrasonic cleaner (Laboratory general equipment)
Ultrasonic cleaners are a type of ultrasonic cleaner. Usually, small ultrasonic cleaners are called ultrasonic cleaners.
Ultrasonic cleaner principle
Ultrasonic cleaner principle is mainly through the transducer, the sound energy of the ultrasonic power source is converted into mechanical vibration, and the ultrasonic wave is radiated into the cleaning liquid in the tank by cleaning the wall of the tank. Due to the radiation of the ultrasonic waves, the microbubbles in the liquid in the tank can be vibrated by the action of the sound waves. Destruction of the adsorption of the dirt and the surface of the cleaning part causes the fatigue layer of the sewage layer to be dislocated, and the vibration of the gas-type bubble scrubs the solid surface.
When the sound pressure or sound pressure reaches a certain level, the air bubbles will expand rapidly and then close again. During this period of time, shock waves are generated at the moment of bubble closure, causing pressure and local temperature regulation around 1012-1013 Pa. This huge pressure generated by ultrasonic cavitation can destroy insoluble dirt and allow them to differentiate into solutions. Steam cavitation directly impacts dirt repeatedly.
On the one hand, the adsorption of dirt and the surface of the cleaning part is destroyed, and on the other hand, it can cause the fatigue layer of the sewage layer to be detached. The vibration of the gas-type bubble scrubs the surface of the solid. Once the dirt layer can be drilled, the air bubble immediately “ "Drill into" vibration to make the dirt layer fall off. Due to cavitation, the two liquids rapidly disperse and emulsify at the interface. When the solid particles are adhered to the surface of the cleaning part by the oil dirt, the oil is emulsified and the solid particles fall off by themselves. When transmitted in the cleaning liquid, a positive and negative alternating sound pressure is generated, a jet is formed, an impact cleaning part is generated, and a sound current and a micro-acoustic flow are generated due to a nonlinear effect, and ultrasonic cavitation generates a high speed at a solid and a liquid interface. Microfluidics, all these actions, can destroy the dirt, remove or weaken the boundary pollution layer, increase the stirring, diffusion, accelerate the dissolution of soluble dirt, and enhance the cleaning effect of chemical cleaning agents. It can be seen that all liquids can be immersed and the sound field exists where there is a cleaning effect, its characteristics apply to the cleaning of parts with very complex surface shapes. In particular, the use of this technology can reduce the amount of chemical solvents used, thereby greatly reducing environmental pollution.
The second ultrasonic wave propagates in the liquid so that the liquid and the cleaning tank vibrate together at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequency. This vibration frequency is the sound wave frequency, so people hear the click sound.
In addition, in the ultrasonic cleaning process, the bubbles visible to the naked eye are not vacuum core bubbles but air bubbles, which suppress the cavitation and reduce the cleaning efficiency. Only the air bubbles in the liquid are completely towed, and the vacuating vacuum core group bubble can achieve the best effect.
Ultrasonic cleaner cleaning media
With ultrasonic cleaning, there are generally two types of cleaning agents: chemical cleaners and water-based cleaners. The cleaning medium is a chemical action, while the ultrasonic cleaning is a physical action, and the two actions are combined to fully and thoroughly clean the object.
Ultrasonic cleaner power density
The higher the ultrasonic power density, the stronger the cavitation effect and the faster the speed, the better the cleaning effect. However, for high-precision objects with a high surface finish, long-term high-power-density cleaning can cause “cavitation” corrosion on the surface of objects.
