板桥电航枢纽灯泡贯流式水轮机的选型

Bulb tubular turbine lectotype of Banqiao hydropower and navigation project

针对乐山市板桥电航枢纽工程的灯泡贯流式水轮机的选型,详细论述了这类机组选型设计的方法,为板桥电航工程机组的正确选择提供了可靠的依据。主要确定了板桥水电站的比转速ns,比速系数K,单位流量Q11,单位转速n11,转轮直径D1,装置空化系数滓p,吸出高度Hs,飞逸转速nf等。最终选出适合板桥水电站水轮机型号。同时本次选型设计也为同类型电站的机组选型设计提供了重要的参考价值。

The method of selection and design for bulb tubular turbine lectotype of Banqiao hydropower and navigation project is described. The main parameters ns, K, Q11, n11, D1, σp, Hs, nf, and so on are determined by using this method. Meanwhile, this selection and design provides important references for the same type hydropower unit.
