在所有转动型的机器上,使用各种轴间隙密封.这种密封不是百分之百的有效,只能限制沿轴向的泄漏到一个可接受的数量级.通过精确地控制轴和密封装置之间的环状间隙,基本上可以达到这种目的.通常采用如下各种轴间隙密封型式. A variety of shaft clearance seals are used on all rotating machines.This seal is not 100% effective and can only limit axial leakage to an acceptable order of magnitude. By precisely controlling the ring between the shaft and the seal Shaped gap, basically can achieve this purpose, usually adopt the following types of shaft gap seal.
