330MW 机组大修中汽轮机汽封径向间隙的合理配置

摘要

The dynamic between the sealing device of steam turbine,known as steam seal or seal. If the steam seal repair and adjustment of the improper,both affect the unit efficiency,but also to the unit to start the impact. In the steam turbine overhaul,how to properly configure the steam seal clearance has a direct impact on the operation economy and safety.%汽轮机动静之间的密封装置，称为汽封或轴封。若汽封检修调整不当，既影响了机组效率，也对机组开机造成影响。在汽轮机大修中如何合理的配置汽封间隙对机组运行经济性和安全性有直接影响，合理的配置汽封间隙也是大修主要的工作之一。
