1.概述蜗壳结构是混流式水轮机的重要部件,也是水电站厂房中的重要建筑物,蜗壳结构直接影响机组的稳定安全运行,是电站建设中重要的技术问题。在水力方面,蜗壳是将承压的水流导入到水轮机转轮的通道。蜗壳位于水电站发电水力通道的末端,是水压和流速最大的地方。在结构方面,蜗壳结构通常是指由钢蜗壳和座环组成的钢部件与其外围钢筋混凝土组成的整体结构,蜗壳必须满足在承受各
1. Overview The volute structure is an important component of Francis turbine and also an important building in the hydropower station. The volute structure directly affects the stable and safe operation of the unit, which is an important technical issue in power plant construction. In terms of hydraulics, the volute is the channel through which pressurized water flows into the turbine runner. The volute is located at the end of the hydroelectric power station for hydropower stations and is where water pressure and flow rates are greatest. In terms of structure, the volute structure generally refers to the overall structure of a steel component composed of a steel volute and a seat ring and its outer periphery reinforced concrete. The volute must meet the requirements of each
