    超声波清洗机生产厂家:脱气功能到底是什么?
    2019-8-22 16:31:24
    众所周知,在超声波清洗机生产厂家超声波清洗设备中,有很多脱气功能,即脱气功能到底是什么原理和作用,让下面小编来回答一下:
    As we all know, there are many degassing functions in the ultrasonic cleaning equipment manufactured by the manufacturers of ultrasonic cleaning machines, that is, what is the principle and function of degassing function? Let's answer with the following small edition:
    当超声波进入溶液时,会产生交变压力,用于空化阈值的声波在液体中传播时会产生空化气泡,可以显著提高气体从溶液到气泡的传质速度。空化气泡是由声波稀疏相中的拉伸应力(负压)在溶液中产生的微小气核产生的。空化形成后,如果拉应力持续存在,时空气泡将扩大到初始尺寸的许多倍。在这种情况下,空化泡保持球形,然后继续增长,振动和崩溃。超声波作用下,溶液中的气体成分可以通过气液界面“定向扩散”进入空化泡。汽蚀泡进入生长期。当空泡在溶液表面坍塌时,气体会从空泡中逸出,导致脱气。

    When ultrasound enters the solution, it will produce alternating pressure。 When the sound wave used for the cavitation threshold propagates in the liquid, it will produce cavitation bubbles, which can significantly improve the gas mass transfer speed from the solution to the bubbles。 Cavitation bubbles are generated by tiny gas nuclei generated by tensile stress (negative pressure) in the acoustic sparse phase in solution。 After the formation of cavitation, if the tensile stress persists, the spatiotemporal bubbles will expand to many times the initial size。 In this case, the cavitation bubble remains spherical and then continues to grow, vibrate and collapse。 Under the action of ultrasound, the gas composition in the solution can enter the cavitation bubble through directional diffusion at the gas-liquid interface。 Cavitation bubbles enter the growth stage。 When the void collapses on the surface of the solution, the gas escapes from the void, leading to degassing。

    超声波除气设备的优点是,泡沫是大量气泡形成的,超声波除气设备是在泡沫形成的早期阶段,在大量气泡不去除气液进行除气、除气之前,或溶解、混合在液体中进行除气、除气。整个过程不使用任何消泡剂,是一种完整的物理消泡模式,也称为机械消泡模式。对于已经产生的表面泡沫,超声波清洗机生产厂家该设备的功能不明显,需要配合消泡膜来解决。
    The advantage of the ultrasonic degassing equipment is that the foam is formed by a large number of bubbles. The ultrasonic degassing equipment is in the early stage of foam formation. Before a large number of bubbles do not remove gas or liquid, degassing or degassing, or dissolving and mixing in the liquid, degassing and degassing are carried out. The whole process does not use any defoamer, is a complete physical defoaming mode, also known as mechanical defoaming mode. For the surface foam that has been generated, the function of the equipment of the ultrasonic cleaner manufacturer is not obvious and needs to be solved with the defoaming film.
    脱气的主要应用是超声波“定向扩散”,一旦产生空穴,内部仍有空气,在一些熔体脱气净化应用中不能产生最好的空穴。排出液体空气,减少超声波空化反应对气泡的阻力,提高超声波清洗机的效率。还有一个作用就是超声波清洗机工作时间长了会产生一种超声波疲劳,降低清洗效果和效率,气功排氧也能消除这种超声波疲劳。
    The main application of degassing is directional diffusion of ultrasound. Once cavitation occurs, there is still air in the interior. In some applications of degassing and purification of melt, the best cavitation can not be produced. Discharge liquid air, reduce the resistance of ultrasonic cavitation reaction to bubbles, improve the efficiency of ultrasonic cleaning machine. Another function is that the ultrasonic cleaning machine will produce a kind of ultrasonic fatigue when it works for a long time, which will reduce the cleaning effect and efficiency. Qigong exhaust oxygen can also eliminate this kind of ultrasonic fatigue.
    综上所述,可以看出超声波清洗设备是非常强大的,而古特超声波产品具有一定的气功能量,可以更好地达到清洗的目的,提高清洗效果。
    In summary, we can see that the ultrasonic cleaning equipment is very powerful, and the Gutt ultrasonic products have a certain amount of gas function, which can better achieve the purpose of cleaning and improve the cleaning effect.
