| 摘 要： | 结合反渗透海水淡化高压泵的能耗状况,合理选择了万吨级反渗透海水淡化高压泵的泵型,提出了一种轴向吸入节段式高压多级泵的新型结构型式.在已有高效水力模型的基础上,对影响效率的几个关键水力尺寸进行不同的优化组合,设计了6种叶轮模型和2种导叶模型,组合成6组水力模型.应用CFD方法对6组水力模型进行了性能预测,挑选出2组效率高(预测)的水力模型制作成2台单级模型泵进行试验研究.2组水力模型试验表明,泵的流量、扬程满足高压泵的要求,其中最优模型的效率达到了79.72%.

| Abstract: | Considering the energy consumption of the HP-pump for SWRO,a reasonable type of high pressure pump was selected,and a new structure of the axial suction segment multistage pump was proposed.Based on the existing effective hydraulic models,through optimizing several key hydraulic dimensions which affect the efficiency,six kinds of impeller models and two kinds of guide vanes were designed,and six groups of hydraulic models were assembled.Performance characteristics of these models were predicted by using the... |
