轴流式水轮机轴流式水轮机axial flow turbine 水流由轴向进人、轴向流出转轮,将水流能量转换为旋转机械能的反击式水轮机。按其转轮叶片能否转动又分为轴流转桨式和轴流定桨式。轴流式水轮机的使用水头范围一般为3一80m。 结构及其特点轴流式水轮机的结构比较复杂,主要部件包括蜗壳、座环、顶盖、导水机构、转轮室、转轮、底环、尾水管、主轴(见水轮机主轴)、导轴承(见水轮机导轴承)等,见图1,图中同时标示出水流流向。 ┌───┐ │ 一├───┐ │:… │ 10│ │:…: │书 │ ┌─┬─┬──┐│ ├───┘ ┌─┐│厂│! │「 │└───┘ │卫│├─┼─┼──┤ │ ││r-│t │r一 │ │ │├─┼─┼──┤ │ ││厂│l │巨 │ │ │├─┴─┼──┘ │ ││尸一 │ └─┘└───┘ ┌─────┐ │扮一一2【 │ └─────┘ 图1轴流式水轮机结构图1一蜗壳;2座环;3顶盖;4导水机构;5转轮室;6一底环;7转轮;8一尾水管;9一主 轴;10一导轴承;11一转轮叶片 轴流式水轮机的蜗壳一般为混凝土浇筑型,水头较高时,亦用钢制蜗壳。混凝土蜗壳是直接在厂房水下部分大体积混凝土中浇筑成的蜗形空腔,断面形状一般为“T”形或“尸,形,钢制蜗壳的断面为圆形。转轮室分为中环和下环两个部分。 轴流式水轮机的转轮包括转轮体(亦称轮毅)叶片和泄水锥。定桨式转轮叶片按一定角度固定于转轮体上;转桨式则在转轮体内设有一套使叶片转动的操作和传动机构。转轮体有圆柱形和球形两种。转轮叶片的数目一般为4一6个,小型低水头水轮机也有采用3个叶片的。轴流转桨式水轮机具有双调节性能.即导叶及转轮叶片均可调节,而定桨式则只能调节导叶。因而,轴流转桨式水轮机能在水头和负荷变化较大范围内保持水轮机的运行稳定性和高效率,从而比定桨式应用得更为广泛。 发展简史及趋势1912年.捷克人V.卡普兰(V.Kaplan)提出一种带外轮缘.叶片固定的轴流式水轮机,如图2所示,经过多年的逐步完善,发展成为现代的轴流转桨式水轮机,亦称卡普兰式水轮机。 轴流式水轮机的应用不断向高水头、大尺寸发展。
