一、前言回流油封是指在普通油封唇的工作面上加上不同的花纹结构,当轴旋转时,这些花纹结构起着泵的作用,即在密封面上产生一定的粘性剪切力,迫使泄漏的流体回流(Feed-Back),收到了减少泄漏或不漏的效果,这一类油封我们通称之为“回流油封”。在旋转密封技术上,利用流体本身的力学的这种“回流”作用,这确是国际上近几年的一个很大的发展,应该引起重视,并期望在我国生产中得到应用。
I. Introduction Return oil seal is the common oil seal lip face plus a different pattern structure, when the shaft rotation, these patterns play a role in the pump structure, that is, the sealing surface to produce a certain amount of viscous shear force, forcing Leaking fluid-back (Feed-Back), received the effect of reducing leakage or no leakage, this type of oil seal, we call it the “return oil seal.” In the rotary seal technology, the use of fluid itself mechanics of this “back flow” effect, this is indeed a great development in recent years, should pay attention to, and hope that our production has been applied.
