谏壁泵站改造进出水流道设计方案试验研究

Research on reform design schemes for inlet and outlet conduit for Jianbi pump station

针对谏壁泵站增容量较大而进出水流道尺寸并不富裕的问题,试图对流道进行适当的改造来提高泵站效率.经过对进出水流道多种改造方案的装置试验研究,得出流道小改小动对提高泵站效率作用不大的结论,最后通过选择合适的水力模型达到了增容40 m3/s的目的,取得了显著的经济和社会效益.

In the view of the problem that the expanding capacity of Jianbi pump station is large while the size of its inlet and outlet conduit is not plentiful, some reforms are done on the conduits to improve the station efficiency. According to unit experimenting research on several reform schemes, the result is that the small-scale reform has little effect on the efficiency. And at last, by selecting suitable hydraulic models, the capacity is increased by 40 m^3/s which resulting in great economic and social effect.
