Analysis and Handling of Abnormal Vibration of M701F4 Gas Turbine Bearings
Compared with steam turbines,gas turbines only have bearing vibration measurement points and lubricating oil temperature measurement points,and lack axial displacement,differential expansion and other measurement points.As a result,when abnormal vibration occurs in gas turbine units,it is difficult to investigate the cause of the fault.Generally,it is difficult to find the cause of vibration in a short period of time,and the fault diagnosis accuracy is low,but the chance of failure is large.Based on this,taking M701F4 gas turbine bearing vibration anomaly as the research object,the function of shaft vibration measurement and bearing configuration of M701F4 gas turbine are firstly analyzed,then the causes of abnormal vibration and inspection results are analyzed in detail,and finally the preventive measures for abnormal bearing vibration are proposed,aiming to better exert the performance of M701F4 gas turbine bearing.Improve its operational efficiency.
