摘要
分析广东沙角A电厂200 MW机组1号汽轮机因轴封系统疏水不畅,导致机组启动过程高、中压缸温差大及冲转过程中汽轮机振动增大的原因和现象,提出就1号汽轮机轴封系统疏水加装疏水管道改造方案,并介绍改造效果。
This paper analyzes the reasons and phenomenon of high unit startup process,the large temperature difference of intermediate pressure cylinder, and the turbine vibration in- creases in the process of rushes, which are caused by shaft sealing system＇s poor hydrophobic in Guangdong Shajiao A Power Plant 200 MW Unit 1 turbine. The rehabilitation pro- grams for No. 1 installation of drains for turbine shaft sealing system hydrophobic have been putted forward, to ensure the safe operation of unit.
