大套一站水泵装置模型试验研究

摘要

大套一站是集灌溉、排涝、降渍等多功能于一体的水利工程.为了保证大套一站安全与高效运行,在初步设计阶段运用计算流体动力学方法,对大套一站进出水流道进行了水力设计优化.优化设计结果表明,水泵的进水条件得到了改善,进出水流道的水力损失明显减小,水泵装置效率得到了提高.为了验证优化设计的效果,进行了水泵装置模型试验.%Datao I Pumping Station is a multi-purpose water convervancy project incorporating with irrigation, drainage and water-log control. To secure its safety and high-efficiency operation, a computational fluid dynamics(CFD) method was adopted to optimize the suction box and discharge pasage of the station in preliminary design. The optimization results indicate that the flow conditions of pump are improved, the hydraulic losses of the suction box and discharge passage are reduced, and the pumping efficiency is raised. The pumping system model tests were carried out to verify the optimization results based on the CFD method.
