摘要(Abstract)：

为了研究泵系统串并联的工作特性，设计了一种由3台泵组成的双进口、双出口的串并联组合形式，通过试验和数值模拟结合的手段对每台泵能量特性进行分析。结果表明，通过对工作模式3不同流量下各泵的流量进行监测，发现并联的一级泵之间流量分布规律并不相同，最大流量差为0.15 Q_d，两者之间流量差值随流量的不断增大呈现先增大后减小的规律；出口1的扬程与M2的扬程较为接近，最大差值为0.188 H_d，与M1的扬程差值较大，最大差值为1.139 H_d；出口2的扬程基本不随工况发生变化，但是受上游2台并联一级泵的混合流态影响会产生波动。研究结果可为离心泵复杂串并联系统的设计和改进提供参考。
In order to study the working characteristics of pump systems in series and parallel connection,a series-parallel combination consisting of three pumps with dual inlet and dual outlet was designed. The energy characteristics of each pump were analyzed through experiments and numerical simulation. The research results indicate that by monitoring the flow rate of each pump under different flow rates in Mode 3,it is found that the flow distribution pattern between the two first-stage pumps in parallel connection is not the same,and the difference between the flow rates of the two pumps shows a pattern of first increasing and then decreasing with the increase of flow rate. Meanwhile,the head of outlet 1 is close to that of M2,the max. difference is 0.188 H_d,the head difference from M1 is relatively big,and the max. difference is 1.139 H_d. Through the analysis,it is found that the head of outlet 2 basically does not change with the working conditions,but its head fluctuates due to the influence of the mixed flow regime of the two first-stage pumps in parallel connection in the upstream. The research results can provide reference for the design and improvement of complex series-parallel centrifugal pump systems.
