摘要
汽封是保证汽轮机动静间尽可能减少泄漏,保证机组热经济性的部件。目前应用种类繁多。在这里介绍了蜂窝式汽封结构特点和在汽轮机应用部位。分析了蜂窝式汽封的基本机理以及与传统梳齿式迷宫密封相比的优越性。
The steam seal is the part of importance to the reduce leakage of the turbine in order to keep the thermal economy of the unit. And the species can be variety. In this paper, the characters and locations of the honeycomb steam seal are introduced. An analysis is made on the supervisory of the mechanism compared with the ones with the traditional comb typed steam seal.
