摘　　要：分析了丁辛醇装置羰基合成3741蒸气透平轴端原粘性螺旋泵送蒸汽密封泄漏量超标的原因,阐述了采用"梳齿-蜂窝可刮削"蒸汽密封对透平轴端密封进行改造的整体过程。解决了轴封泄漏超标的设备故障,提高了我国工业驱动高速蒸汽轮机轴封的设计制造水平,具有推广价值。This paper analyzed the cause for out-of-limit leakage of the original viscous helical pumping steam seals at the3741steam turbine shaft end of oxo synthesis unit of the2-EH plant,and introduced the overall process of using“combing teeth-honeycomb scraped steam seals to make improvement to the seals at turbine shaft end.These solved the equipment failure of out-of-limitshaft seal leakage,improved the design and manufacture level of high speed steam turbine shaft seals of our country,and havepromotional value.
