How does an ultrasonic cleaner work? Now let's introduce to you the main links and steps of the ultrasonic cleaning machine's operation, as well as the principle and knowledge of how the ultrasonic cleaning machine works. The principle of ultrasonic cleaning machines mainly involves the transducer converting the
acoustic energy of the power ultrasonic frequency source into mechanical vibration, which then radiates the cleaning liquid in the tank to ultrasonic waves through the tank wall. Due to the ultrasonic waves radiated by
, the microbubbles in the liquid inside the tank can maintain vibration under the action of sound waves.
When the sound pressure or sound intensity is subjected to pressure to a certain extent, the bubbles will rapidly expand and then suddenly close. During this process of the ultrasonic
wave cleaning machine, an shock wave is generated at the moment the bubble closes, creating a pressure of 1012-1013 Pa around the bubble and local
temperature adjustment. The huge pressure produced by this ultrasonic cavitation can break down insoluble dirt and cause it to decompose in the solution. The direct and repeated impact of steam-type cavitation on dirt.
On the one hand, ultrasonic cleaning machines break the adsorption between dirt and the surface of the cleaning object. On the other hand, ultrasonic cleaning machines can cause fatigue damage to the dirt layer and detach it. The vibration of gas-type bubbles scrubs the solid surface. Once there is a gap in the dirt layer that can be drilled, the bubbles immediately ";" "Drill into" Vibration causes the dirt layer to fall off. Due to cavitation, the two liquids rapidly disperse and emulsify at the interface. When solid particles are wrapped by oil and adhere to the surface of the cleaning object, the oil is emulsified and the solid particles fall off by themselves. When ultrasonic waves propagate in the cleaning liquid, they generate alternating positive and negative sound pressures, forming a jet. Impact cleaning of the parts, at the same time, due to nonlinear effects, acoustic flow and micro-acoustic flow will be generated. Ultrasonic cavitation at the interface between solids and liquids will produce high-speed micro-jets. All these effects can break down dirt, remove or weaken the boundary
dirt layer, and increase stirring and diffusion effects. Accelerate the dissolution of soluble dirt and enhance the cleaning effect of chemical cleaning agents. From this, it can be seen that wherever a liquid can reach and a sound field exists, there is a cleaning effect. Its characteristics are suitable for the cleaning of parts with very complex surface shapes. Especially after adopting this technology, the usage of chemical solvents can be reduced, thereby significantly lowering environmental pollution.
Secondly, the ultrasonic cleaner propagates in the liquid, causing the liquid and the cleaning tank to vibrate together at the ultrasonic frequency. When the liquid and the
cleaning tank vibrate, they have their own natural frequencies, which are the frequencies of sound waves, so people can hear a buzzing sound.
In addition, during the ultrasonic cleaning process, the bubbles visible to the naked eye are not vacuum cluster bubbles but air bubbles, which inhibit cavitation and reduce the cleaning efficiency. Only when the air bubbles in the liquid are completely dragged away can the vacuum nucleus
group bubbles of cavitation achieve the best effect.
