Analysis and treatment of oil film whirl of a 57MW steam turbine generator set
Oil film whirling is one of the common faults in steam turbine,which will cause damage to equipment during operation.a 57MW turbogenerator unit taken as an example,in this paper,the abnormal rise of#3 bearing vibration after A-class repair is described,and the oil film whirling fault is accurately identified by analyzing the vibration characteristic data and running adjustment experiments.By scraping and adjusting the center of the bearing,the bearing stability is improved,the oil film thickness is maintained,the oil film eddy fault iseliminated,and the stable operation of the turbine generator set is guaranteed.
