轴流泵站的进、出水流道布置,对泵的正常运行、效率以及泵站建设工程量(造价)有很大影响.近年来大型轴流泵的发展,对水工建筑物的经济性及水力条件,提出更高的要求,也出现一些新的结构型式.轴流泵进、出水流道布置可以是整体考虑的,如贯流式泵组的直管形流道,斜式或轴伸式泵组的半管型流道;也可以是分立的,如肘型或钟型进水流道,蜗室出水流道、虹吸式或直管式出水流道等.而分立的进、出水流道可以是多种组合的形式.
Axial flow pump station inlet and outlet flow channel layout, the normal operation of the pump, the efficiency and pumping station construction project (cost) has a great impact.In recent years, the development of large-scale axial flow pump, hydraulic structure of the economy And hydraulic conditions, put forward higher requirements, but also some new structure type. Axial flow pump inlet and outlet flow channel layout can be considered as a whole, such as the tubular pump straight flow channel, inclined or shaft Extension pump group of semi-tubular flow channel; can also be discrete, such as elbow-shaped or bell-type intake runner, worm outlet channel, siphon or straight tube outlet channel, etc .. The separate into, out The water runner can be in a variety of combinations.
