摘　　要：通过对试验结果分析,阐述了汽轮机组通流部分级间吸漏状况,剖析了其内部基理,并对其影响级性能的因素作了论述。关于叶轮平衡孔的存在对级性能的影响,通过两种方案的试验,概论了其漏气对级效率的影响。两项试验都为设计较好的汽轮机组通流部分提供了指导。This article introduces the experimental result of the leak out flow between turbine stages, and it analyses the different ingredinets which influence the efficiency. Through the two different designed experiments of the leak-out flow of the balance holes, its influence to the stage efficiency is presented which gives reference for the design.
