前言1973年我们承担了江淮磷矿输水工程设计任务。此工程的特点是;管道长(10公里以上),位差大(95米),单根管输水,一、二级水泵串联加压。在这样既定条件下,如何保证安全输水的大课题,就严峻地摆在我们面前。以往从未碰到过这样长的管道,尤其对一、二级泵串联加压时管道水锤的消除更感无从下手。怎么办?我们在领导支持下,带着上述问题去西南和中南给水排水设计院,
Foreword In 1973, we undertook the design task of the Jianghuai Phosphorus Mine Water Delivery Project. The characteristics of this project are: long pipeline (above 10 kilometers), large difference in position (95 meters), single-pipe water conveyance, primary and secondary pumps in series pressure. Under such established conditions, how to ensure the safety of the major issues of water transportation is seriously before us. In the past, such a long pipeline has never been encountered, especially for the elimination of pipeline water hammers when the first and second pumps are pressurized in series. How should we do? With the support of the leadership, we will go to the Southwest and Central South Water Supply and Drainage Design Institute with the above problems.
