汽轮机真空低的原因分析及处理

Analysing of the Causes of Lower Vaccum in Turbine and Its Solution

分析计算得出汽轮机射水抽气器效率偏低、抽气管路及轴封系统布置不合理、空气管路中积存凝结水以及轴封送汽参数选择欠佳等是造成凝汽器真空低的主要原因。

By analysing and calculating,it concludes that the water-ejector of turbine works at low efficiency、abstraction pipes and sealing steam systems layout unreasonablely、condensate water accmulates in the air pipes and the sealing steam parameters are badly chosen can form low vacwm in condenser.
