目前,国内各水轮机制造厂生产的各种小型水轮发电机组,几乎都是国家定型产品、统一设计。即在一定水头、流量、出力情况下,水轮机的直径、转速等均已标准化系列化。这无疑是正确的,它给我们的工作带来了极大的方便。然而实践证明,由于自然条件的千差万别,同时水力开发受开发者的能力、建站处地形、地质以及当地负荷需求诸因素的限制,需要选择的机型是多种多样的。
At present, all kinds of small-scale hydro-generating units produced by domestic turbine factories are almost all national stereotyped products and have a unified design. That is, in a certain head, flow, output case, the turbine diameter, speed, etc. have been standardized series. This is undoubtedly correct, it has brought great convenience to our work. However, practice has proved that due to the vast variety of natural conditions, and hydraulic development by the developer’s ability to build station topography, geology and local load demand and other factors, the choice of models are varied.
