有些社队,由于连年干旱,地下水位大幅度下降,离心泵下卧深度达10米或更多。这种情况,离心泵抽水较少,轮灌周期拖长,耗能多,不安全,不如用深井泵经济合理。侯庄公社官西三队,有一眼40米深的机井,离心泵下卧10米仍抽不上水来,成了废井。1979年秋天,装上一台扬程30米的深井泵,每小时出水40米~3,废井变成了活井。索镇西镇大队一、三生产队,在镇西有177.5亩地,原用5台离

In some communes and teams, due to successive years of drought, the groundwater level has dropped drastically. Centrifugal pumps have a depth of 10 meters or more. In this case, less centrifugal pump pumping, irrigation cycle longer delay, energy consumption, unsafe, it is better to use a deep well pump economy and reasonable. Houzhuang commune officials West Third Team, a glance 40 meters deep wells, 10 meters below the centrifugal pump is still pumping water, became a waste well. In the autumn of 1979, a deep well pump with a lift of 30 meters was installed, and the effluent was 40-3 per hour. The waste well became a well.
