摘要 阐述了汽封原理、蜂窝汽封的结构特点。通过传统汽封间隙调整后和蜂窝汽封在汽轮机上使用后的试验结果分析其节能效果。 The principle of vapor seal, the structure and the application of honeycomb vapor seal were presented in this paper. Then it shows the effect of energy-saving by analyzing the experiment results of the improved vapor seal and the modified traditional clearance in steam turbines.
