浙江省低洼易涝区排涝泵站进出水流道研究

Study on Inlet and Outlet Runners of Pumping Station in Low-lying and Floating Areas

依据管路效率的公式,分析了提高管路效率的主要途径.根据进水流道和出水流道的类型,研究了进水流道和出水流道尺寸对效率的影响,并提出了断流设施拍门在增大开启角度、改变结构型式和减轻撞击力等方面进行更新改造.研究结果对浙江省低洼易涝区排涝泵站的更新改造和高效运行具有指导作用,有望补充泵站技术的有关标准和规程.

On the basis of pipeline efficiency formula,main ways of increasing the efficiency of the pipeline are analyzed in the paper.According to the types of inlet and outlet runners,the effect of their sizes on the efficiency is also studied.At the same time,such measures as increasing open angle,changing structure type and reducing percussive force are put forward for the replacement and renovation of flap valve,which is of directive function on efficient operation of pumping station in low-lying and floating areas in Zhejiang province.It is expected to supplement relevant standards and procedures for pump technology to some extent.
