What Is The Principle And Function Of The Degassing Function in The Ultrasonic Cleaner?

When ultrasonic waves are introduced into the solution, alternating pressures are generated, and the acoustic waves used for the cavitation threshold can generate cavitation bubbles when propagating in the liquid and can significantly increase the mass transfer rate of the gas from the solution to the bubbles. Cavitation bubbles are created by tiny gas nuclei in the solution, which are created by tensile stress (negative pressure) in the sparse phase of the acoustic wave. If the tensile stress persists after the formation of the cavitation, the cavitation bubble will expand to many times its original size. In this case, the cavitation bubble maintains a spherical structure and then continuously grows, vibrates, and collapses. Under the action of ultrasonic waves, the gas components in the solution can enter the cavitation bubbles through "directional diffusion" through the gas-liquid interface, and the cavitation bubbles enter the growth stage. When the cavitation bubbles collapse on the surface of the solution, the gas will escape from the bubbles. caused degassing.

Degassing ultrasonic cleaner

The advantages of ultrasonic degassing equipment, are foam is a large number of bubbles, and ultrasonic degassing equipment is to defoaming and degassing the liquid in the early stage of foam formation and before the bubbles accumulate in large quantities, or to dissolve and mix the gas in the liquid. Defoaming and degassing. The whole process does not use any defoaming agent, and it is a complete physical defoaming method, which can also be called a mechanical defoaming method. For the surface foam that has been generated, the effect of this equipment is not obvious, and it needs to be solved together with the defoaming film method.

What is the principle and function of the degassing function in the ultrasonic cleaner?

Degassing mainly uses ultrasonic "directional diffusion". Once cavitation occurs, there is still air inside. In some melt degassing and purification applications, it is best to not generate cavitation. The air of the liquid is discharged, reducing the resistance of the bubbles generated by the ultrasonic cavitation reaction, and enhancing the cleaning efficiency of the ultrasonic cleaning machine. Another effect is that the ultrasonic cleaning machine will produce a kind of ultrasonic fatigue after working for a long time, which reduces the cleaning effect and efficiency. The oxygen exhaust and degassing function can also eliminate this ultrasonic fatigue.

What is the principle and function of the degassing function in the ultrasonic cleaner?

In summary, it can be seen that the degassing function of ultrasonic cleaning equipment is very powerful, which can better achieve the purpose of cleaning and improve the cleaning effect.
