近几年,由于连续干旱和工农业用水量的不断增加,使井灌区地下水位大幅度下降。离心泵受真空的吸程的限制,继续下卧已有困难,于是就大量改用长轴泵抽水。据不完全统计,我县已发展长轴泵三千多台,全省约有10万余台。因选型落后和安装使用技术水平不高,普遍存在水泵耗能多、装置效率低等问题。为了提高装置效率、节约能源、降地浇地成本,我们
In recent years, due to successive droughts and the continuous increase of industrial and agricultural water consumption, the water table of well irrigation areas has dropped drastically. Centrifugal pump vacuum suction limit, to continue to have difficulty lying down, so a large number of long-axis pump instead. According to incomplete statistics, our county has developed more than 3,000 long-axis pumps and the province has about 100,000 sets. Due to the selection of backward and installation technology is not high, the prevalence of pump energy consumption, low efficiency and other issues. In order to improve plant efficiency, save energy, reduce groundwater costs, we
