摘要 在分析不同贯流泵装置的结构特征和常用断流方式技术特点的基础上,针对城市防洪泵站扬程低、年运行时间较短、安全可靠性要求高的特点,设计了一种竖井进水、虹吸出水和真空破坏阀断流的新型竖井贯流泵装置.以盐城市某泵站工程为例,运用计算流体动力学方法,利用RNG  k-ε湍流模型闭合雷诺时均N-S动量方程组,以适应具有较大曲率的虹吸式出水流道内部流动,采用多重参考坐标系方法(MRF)处理叶片动静耦合,采用SIMPLEC算法实现压力与速度的耦合求解,对该新型竖井贯流泵装置的模型进行了数值分析和性能预测.计算结果表明:经初步优化设计的新型贯流泵装置模型,内部流态平顺,在设计扬程为1.15 m、流量为0.326 m3/s的工况下,装置效率达56.0%;在最高扬程为1.95 m、流量为0.296 m3/s的工况下,装置效率达到68.8%.

Abstract: Based on comparing structural features of different tubular pumping systems and technical characteristics of cut off devices in common use, aiming at the characteristics of low head, shorter  annual  operation time and higher safety and reliability requirements of city flood control pumping stations, a new type shaft tubular pumping system was invented, which is composed of a shaft suction box, a tubular pump and a siphon type discharge passage with a vacuum breaker valve as cutoff device. Taking a real pumping station in Yancheng city as an example, the computational fluid dynamics  method  was adopted to analyze the internal flow of the new type model tubular pumping system and predict its energy performances. The time averaged Navier-Storks equations were closed by RNG k-ε turbulent model to adapt internal flow of siphon type discharge passage with larger curvatures. The method of multi-reference frame(MRF) was used to deal with the coupling of rotating impeller and static guide vane, and SIMPLEC algorithm was adopted to achieve the coupling solution of velocity and pressure. Computational results show that the internal flow of the new type shaft tubular pumping system through preliminary optimization is smooth, and the model pumping system efficiency reaches 56.0% when the design head and the relevant discharge are 1.15 m and 0.326 m3/s respectively, and up to 68.8% when the maximum head and the relevant discharge are 1.95 m and 0.296 m3/s respectively.
