摘　　要：离心泵并联运行是增大管道流量的重要手段,广泛应用于日常生活中。为了确定离心泵实际并联运行的工作特性,搭建了一套离心泵并联试验装置。在大量试验的基础上,详细分析得到了实际运行性能曲线,并通过两种节流调节方式进行了水泵并联运行经济性分析,旨在为离心泵并联应用提供参考。Centrifugal Pumps in parallel operation has been an important means to increase pipe flow and widely used in our daily life. In this paper, a suit of testing equipments was established for confirming the actual performance charac- teristics of centrifugal pumps in parallel operation. On the basis of abundant tests, the actual performance curve was analyzed and gained, and economical analysis of centrifugal pumps in parallel operation was carried out by means of two throttle regulation modes. It can provide reasonable and beneficial reference to operate centrifugal pumps in parallel.
