摘要
针对气体压力低于9.8 kPa的情况,提出一种对旋转竖轴进行气体密封的结构。它除了具有旋转轴唇形密封圈本来的密封作用外,还有利用润滑油表面张力来提高对气体的密封作用。这种结构简单,使用寿命较长。
In the case of gas pressure lower then 9. 8 kPa, a kind oi gas seal structure used for vertical rotary shatt is presented in this paper. In addition to the original shaft lip seal, it also uses the surface tension of lubrication oil to improve the seal effect on gas. It is characterized by its simple structure and longer service life.
