摘　　要：离心泵并联是改变输送系统运行工况的一种重要方法。应用两台同型号离心泵设计了并联实验平台,对不同转速、不同管路特性下的离心泵并联运行开展实验研究,基于实验数据分析各种因素对系统流量的影响规律。研究结果为优化并联泵配置、提高运行效率提供参考。Parallel operation of centrifugal pump is an important method of changing working condition of system. Test bed of par- allel operation of centrifugal pumps was designed using two centrifugal pumps of the same type. Tests had been conducted under differ- ent kinds of rotational speeds and different pipeline characteristic. The impact of various parameters on system flow was analyzed based on the experimental result. The research results are of practical Value for optimizing pump configurations and improving the economic ef- ficiency of pump operation.
