本文在综述回转机械故障诊断的原理和有关方法的基础上,讨论转子碰磨故障的机理,对单盘转子碰磨试验作了分析,探讨如何识别碰磨故障。本文还对125MW汽轮机转子的实测结果作了初步分析。
Based on the review of the principle of rotary machinery fault diagnosis and related methods, this paper discusses the mechanism of rotor touch failure and analyzes the abrasion test of single disk rotor to find out how to recognize the touch failure. This paper also made a preliminary analysis of the measured results of 125MW steam turbine rotor.
