我县是个老井灌区,现有水泥管机井9646眼。近几年由于连续天旱和工农业用水量增加,造成地下水过量开采,水位大幅度下降。原来普遍使用的离心泵,因受真空吸上扬程限制被淘汰。换上长轴井泵,解决了地下水提取困难的问题。可农民普遍反映,使用长轴井泵后,机井损坏报废多。有个村24眼机井,井井安装长轴泵,三年来损坏报 My county is an old well irrigation area, the existing cement pipe wells 9646. In recent years, due to successive droughts and increased use of water for industry and agriculture, over-exploitation of groundwater has drastically reduced the water level. The original universal centrifugal pump, vacuum suction head lift due to be eliminated. Replace the long axis well pump to solve the problem of difficult extraction of groundwater.
