摘　　要：近年来，某机组汽轮机在运行时其转子由负推力定位，在采取了一些措施后，也没有明显改善。本文对汽轮机转子呈负推力的原因进行了诊断，并根据现场实际情况提出了平衡汽轮机转子轴向推力的措施，并对汽轮机转子如何能够获得正向推力进行了探讨。One turbine rotor was located by negative thrust in recent years. After some measures,this phe-nomenon was little improved. This paper diagnoses the reason of negative thrust in turbine rotor, puts for-ward measures to balance the axial thrust according to worksitc, and probes into the methods which can lo-cate the turbinc rotor by positive thrust.
