Analysis on High Temperature Faults for Thrust Bearing of Turbine and Improvements

The high temperature faults often occurred to the thrust bearing of a co-generation turbine leading to poor economy and safety of the unit.The causes of the faults were analyzed in detail by the measurement of the bearing during the maintenance.Some measures were taken to eliminate such faults.Actual operation of the unit showed that the measures were effective to lower the bearing temperature to meet the operating demand.
