| 摘 要： | 大型灯泡式贯流泵在国内的研究与运用远远滞后于水轮机,导致国内低扬程泵站的选型一直突破不了传统的结构模式。为了研究解决国内低扬程泵结构选型问题,结合南水北调东线工程的蔺家坝泵站大型灯泡贯流泵,对适用低扬程工况的大型灯泡式贯流泵结构形式、流道水力损失、压力分布、流速分布进行了流体数值计算,并与模型试验作了比较。结果表明,流体数值计算的结果与试验数据非常接近,这为今后国内低扬程泵站设计选型提供了参考。

| Abstract: | In order to solve the domestic structure selection problem of low-lift pump,based on the large-scale bulb tubular set of Linjiaba pumping station in South-to-North Water Diversion Eastern Route Project,a Computational Fluid Dynamic(CFD) study on structure,flow channel hydraulic loss,pressure distribution and flow rate distribution of the large-scale bulb tubular pump suitable for low-lift operating mode is conducted.The simulated results are compared with the model experiment.Results indicate that CFD results approach the experiment data.The study provides references for structure choice and design of domestic low-lift pump station.large-scale pumping station;low-lift;bulb tubular pump;computational fluid dynamic |
