江苏、广东等省及东北三江平原地区农田排灌,大部分水位差在2米左右,而翻水量却要求较大。据此,我院排灌机械研究所开发了低扬程、大流量、干式电机的轴流式潜水电泵。该泵结构新颖,机电一体,具有高效、节能、安装方便、适应性强、使用可靠等优点,其综合技术指标达到国内先进水平。且泵站土建投资比同参数通用泵节省30～50％,因而受到用户及水利部门一致好评,推广应用前景广阔。
Jiangsu, Guangdong and other provinces and northeast Sanjiang Plain farmland irrigation and drainage, most of the water level difference of about 2 meters, while the volume of water is required more. Accordingly, our institute drainage irrigation machinery research and development of low lift, large flow, dry-type motor axial submersible pump. The pump structure of a new, mechanical and electrical integration, with high efficiency, energy saving, easy installation, adaptability, reliability, etc., its comprehensive technical indicators have reached advanced domestic level. And civil engineering pump investment than the same parameters of common pump to save 30 to 50%, which by the user and the water sector unanimously praised the promotion of broad application prospects.
