| 摘 要： | 针对泵站系统变流量时泵站并联机组调速运行工况点难以确定的问题，分析了相同型号、相同管路布置时多泵并联的运行特性。在此基础上，通过简化管路约束，应用离心泵性能特性和流体机械相似原理对泵站多泵并联工作机组的运行特点进行了分析和研究，建立以系统流量为约束条件下的调速特性数学模型，讨论了多泵并联系统调速时的系统性能，并给出并联调速机组单泵调速情况下的工况点计算方法。

| Abstract: | The parallel-connection operation characters of the centrifugal pump groups with the same type and pipeline layout are discussed. By simplifying the restrictions of pipeline the variable-speed operation characters of the parallel-connection centrifugal pump groups are analyzed based on the ce performance and the similarity principle. The variable-speed mathematical model under condition of system flow fate is established, based on which the variable-speed operation are discussed and the relevant calculation methods are given. ntrifugal pump the restrained characteristics |
