【摘要】 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。本文研究基于对三峡左岸3号机组的水推力真机试验,论述了在交负荷运行条件下水轮机的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比较和探讨,为国内外大型电站的设计和安全运行提供了宝贵经验。更多还原

【Abstract】 The research of the axial thrust is very important to the running of hydroelectric generating sets and the thrust bearing design. This paper is based on prototype test of axial thrust for No. 3 unit of Three Gorges Left Bank Hydropower Station, presents the characteristics of the axial thrust under load variation conditions. It also compares the experimental results with the predicting numerical data in order to provide valuable experience for design and maintenance of similar large sets.更多还原
