Analysis on reasons of higher temperature at bearing bush of turbine

Abstract

Abstract:

Abstract:The reasons of higher temperature at bearing bush No.2 of the 350MW unit in a power plant were analyzed. The key factors influencing on the temperature of tilting bearing bush were expounded. Some measures were adopted, which include to adjust the load distribution of the bearing bushes, to select the oil gap of bearings rationally, to scrape the input and output oil wedges of the tilting bearing bushes and others. The temperature of the bearing bush lowered obviously, and the safe operation of the unit is ensured.
