轨道交通地下区间道床泵房设计

Road Bed Pump Room Design of the Underground Section of the Rail Transit

道床泵站设计选型受集水坑深度、提升高度、水输水长度、并联数量的限制,需要对其进行计算分析。论文选取国内常用品牌道床泵,对管路特性曲线和水泵性能曲线进行拟合与计算,确定设计边界条件下道床泵的最终选型,为设计人员进行轨道交通地下区间道床泵设计选型提供一种计算方法。

The design selection of bed pump station is limited by the depth of catchpit,lifting height,water transmission length and parallel quantity,which needs to be calculated and analyzed.The domestic road bed pump is selected to fit and calculate the pipeline characteristic curve and pump performance curve,the final selection of bed pump under design boundary conditions are determined,which can provide a calculation method for the designers to design the underground interval bed pump in rail transit.
