三峡电站左岸6号机组轴向水推力真机试验研究

The Prototype Test of Axial Thrust for Unit 6 of Three Gorge Left Bank Hydropower Plant

水力机组的轴向水推力研究对电站的稳定性、可靠性以及推力轴承的合理设计具有重要意义。本文基于三峡水电站左岸6号机组的水推力真机试验,论述了变负荷运行条件下水轮机轴向水推力的变化规律, 并对计算预测结果与试验结果进行了比较和探讨。

The research of the axial hydro-thrust for hydraulic turbine is very important to the running of hydropower plant and the design of thrust bearing. This paper is based on the prototype test of axial thrust for the unit 6 of Three Gorge power plant. The characteristic of the axial thrust behaviors under the changing of load was presented, and the results of experiment and the numerical prediction ones were compared.
