摘要 基于ANSYS FLUENT软件应用RNG k-ε湍流模型、欧拉—拉格朗日多相流模型,对双吸式离心泵内的水流和泥沙颗粒运动进行了模拟,分析了不同长度、不同相对位置的副叶片对口环保护和水泵效率的影响,分析结果表明:缩短副叶片长度,能有效减小水泵装置效率的降幅,但当副叶片太短时,不能有效减小泥沙对口环的磨损;副叶片由4个减为3个时,水流的挟沙能力得以保持,对口环的保护效果仍然明显,同时还能有效减小水泵装置效率的降幅;通过对比分析,方案7中的副叶片布置形式综合特性最优。

Abstract: The RNG k-ε turbulence model, Euler-Lagrange multiphase flow model were applied to simulate the water flow and movement of sediment in a prototype double suction centrifugal pump based on ANSYS FLUENT software. The influence length and location of back-blades on the concentration of sediment and efficiency of pump was analyzed. The results show: with the decrease of length of the back-blade, the decline of the pump efficiency is decreased; a minimum length of the back-blade is needed to prevent the impeller ring from sand erosion; reduce the number of from four to three is also effective in protecting the impeller ring and keep a reasonable pump efficiency; in this simulation, case 7 is the most effective.
Key wordsDouble suction centrifugal pump   Back blade   Sand erosion   Numerical simulation   optimization
