目前各地建造的農村水电站所利用的水头多在十公尺以下,可是这种低水头电站的單位容量的基建投資却是較高的。針对这一情况提出了一个急待解决的問題,即改進小型水电站的結構,使其更为合理,以期節省貴重的材料,减少建筑工作量,縮短施工期限。本文便是为此目的而提供的新的結構型式。依据水力条件初步选擇水輪机型式时,一般可由圖1的諾模圖选取。
At present, the construction of rural hydropower stations around the country uses more than ten meters of water head, but the infrastructure investment per unit capacity of such low-head hydropower plants is relatively high. In response to this situation, an urgent problem has been raised to improve the structure of small-scale hydropower stations to make them more reasonable in order to save valuable materials, reduce construction workload and shorten the construction period. This article is the new structural style provided for this purpose. According to the hydraulic conditions of the initial choice of turbine type, generally selected by the nomogram in Figure 1.
