| Abstract: | The paper aims at the fact that operation temperature of the thrust bearing of 4# steam turbine is a little higher, and based on the further investigation and comparison with the current criteri- on, the target is assured that the temperature is not lower than 95℃. The factors that affect the operation temperature of thrust bearing are analyzed and five factors are affirmed as main factors. Measures are taken to help these factors. The results show that the target has been achieved and also provide a technical guidance for remolding a steam turbine. |
