| 摘 要： | 应用有限元分析程序对超临界600MW汽轮机高压缸方案进行三维有限元应力分析，提出采用带有一半圆槽的新型高压隔板套设计方案，可有效降低高压隔板套应力，采用椭圆形汽封结构形式，既可避免动静之间产生碰磨，又能使轴封和隔板汽封有较小的间隙，提高机组热效率，为超临界机组的研究与开发提供理论依据。

| Abstract: | Finite element analysis program is used to analyze thermal stress of high pressure cylinder scheme of supercritical 600MW turbine. I adopt new design scheme of high pressure blade ring with half circle groovy which can availability reduce stress of high pressure blade ring. This thesis proposes ellipse gland seal structure, it can avoid abrasion between rotor and stationary of turbine, and decrease gland seal clearance, improve units thermal efficiency. It is basis of studying and developing supercritical turbine. |
