一、概述为适应喷灌技术发展和解决原喷灌系列泵效率低等问题,“喷灌泵系列更新改进”科研课题于1982年先后列入机械工业部和国家经委节能攻关项目,共有十种泵型,其中八种自吸泵、二种离心泵,流量15～50米~3/时,扬程20～55米,配套功率3～12马力。机械工业部喷灌泵联合设计组经过两年多的大量试验研究,并经水力模型评选,
I. Overview In order to adapt to the development of sprinkler irrigation technology and to solve the problem of low efficiency of the original sprinkler pump series, “sprinkler pump series updated and improved” research project in 1982 has been included in the Ministry of Machinery Industry and the State Economic Commission energy-saving research project, a total of 10 pump, Of which eight self-priming pump, two centrifugal pumps, flow 15 to 50 meters to 3 / hour, head 20 to 55 meters, supporting power 3 to 12 horsepower. Ministry of Machinery Industry Joint Irrigation Pump Design team after more than two years of extensive experimental study, and selected by the hydraulic model,
