摘　　要：通过分析找出了负压轴封漏汽漏气的原因，通过对枝状管系沿程阻力的计算，找到了解决问题的着眼点。这些工作对轴封及其系统的设计、安装和改进都有指导作用。The title finds out the reasons of steam vapour and air breaking off through the vacuum shaftglands. In addition, it finds out the key to the question by caculation linear losses of tree- pipe system.Those works would play an important pole in the drawing,building and upgrade of shaft-glands system.

关 键 词：汽轮机 轴封 沿程阻力
