Influence of Oil Film Structure on Thrust Bearing Temperature

The thrust bearing of the hydro-generator bears a large axial load, and a large amount of heat is generated when the oil film is rubbed. In order to reduce the temperature of the thrust bearing and improve the uniformity of the temperature distribution, it is an effective method to use the three-dimensional fluid field simulation analysis method to carry out fluid-solid coupling heat transfer research. In this paper, the actual operation of the thrust bearing model in the project is used as the analysis object, and the temperature characteristics of the thrust bearing under different oil film structure conditions are analyzed by CFD software. The simulation results are in good agreement with the actual measurement results, indicating that the simulation method can be used to guide the design and optimization of the cooling scheme of the thrust bearing model.
