烟岗电站水轮机机型选择

Type Selection of Water Turbine Frame in Yangang Hydropower Station

烟岗水电站属于高水头电站,在此水头段适合的水轮机机型有混流式和水斗式两种。通过对两种机型特点和两种转轮在国内外设计及生产制造难易程度的比较,以及参考国外厂家的选型意见,针对本电站地形条件、压力管道长等具体情况,选定烟岗水电站水轮机机型。

Yangang Hydropower station belongs to the hydropower station with water head ,under which ,there are two types of water turbines, that is, maixed-flow turbine and Pehon turns, which are suitable. Through the comparison of type behaviors of mixed-flow turbine with Pelt on turbine as well as of the home and abroad design and easy or difficult manufacturing and production of two types of turbines, and with the reference to the manufacturers＇ suggection abroad, this paper describes the type selection of water turbine for Yangang Hdropower station with an aim at the concrete conditions such as topographical conditions and the length of penstock, etc.
