單槽超聲波清洗機的空化現(xiàn)象

隨著單槽超聲波清洗機的不斷迭代升級,在很多行業(yè)中得到了廣泛的應(yīng)用。而單槽超聲波清洗機原理主要是通過換能器,將功率超聲頻源的聲能轉(zhuǎn)換成機械振動,通過清洗槽壁將超聲波輻射到槽子中的清洗液。

With the continuous iteration and upgrading of single slot ultrasonic cleaning machines, they have been widely used in many industries. The principle of a single slot ultrasonic cleaning machine is mainly to convert the sound energy of the power ultrasonic frequency source into mechanical vibration through a transducer, and radiate the ultrasonic wave into the cleaning solution in the tank through the cleaning tank wall.

由于受到超聲波的輻射,使槽內(nèi)液體中的微氣泡能夠在聲波的作用下從而保持振動。破壞污物與清洗件表面的吸附,引起污物層的疲勞破壞而被駁離,氣體型氣泡的振動對固體表面進行擦洗。

Due to the radiation of ultrasound, the microbubbles in the liquid in the tank can maintain vibration under the action of sound waves. Disrupting the adsorption of dirt on the surface of the cleaning part, causing fatigue damage to the dirt layer and detachment, and the vibration of gas bubbles scrubbing the solid surface.

在液體中傳播的超聲波能對物體表面的污物進行清洗,其原理可用“空化”現(xiàn)象來解釋:超聲波振動在液體中傳播的音波壓強達到一個大氣壓時,其功率密度為0.35w/cm2,這時超聲波的音波壓強峰值就可達到真空或負(fù)壓,但實際上無負(fù)壓存在,因此在液體中產(chǎn)生一個很大的力,將液體分子拉裂成空洞一空化核。

The ultrasonic wave propagating in liquid can clean the dirt on the surface of an object, and its principle can be explained by the phenomenon of "cavitation": when the sound wave pressure propagated by ultrasonic vibration in liquid reaches one atmosphere, its power density is 0.35w/cm2. At this time, the peak value of the sound wave pressure of ultrasonic wave can reach vacuum or negative pressure, but in reality, there is no negative pressure present, so a large force is generated in the liquid, Crack liquid molecules into voids or cavitation nuclei.

此空洞非常接近真空,它在超聲波壓強反向達到大時破裂,由于破裂而產(chǎn)生的強烈沖擊將物體表面的污物撞擊下來。這種由無數(shù)細(xì)小的空化氣泡破裂而產(chǎn)生的沖擊波現(xiàn)象稱為“空化”現(xiàn)象。

This cavity is very close to a vacuum, and it ruptures when the ultrasonic pressure reaches a high level in the opposite direction. The strong impact generated by the rupture impacts the dirt on the surface of the object. This shock wave phenomenon caused by the rupture of countless small cavitation bubbles is called "cavitation" phenomenon.
