沧州地区,位于华北平原的东部,地势平坦,自西南向东北倾斜,属大陆性半干旱季风气候,冬季寒冷干燥,春季干旱多风,多年平均降雨量为596毫米。据历史资料分折,每年都有干旱威胁,群众有“十年九旱”之说,常常是春旱接伏旱,连续几年大旱也时有发生。因此,我区地上水源缺乏,地下水源不足。一般深100米左右的机井,出水量每小时仅20～30米~3,加之近几年连续干旱,地下水位急剧下降,单井效益降低、能耗增高,机泵更新等原因,每逢春旱,抽空吊泵现象部有出现。据测试分析,在旱季每小时提水
Cangzhou area, located in the eastern part of the North China Plain, is flat and slopes from the southwest to the northeast. It belongs to the continental semi-arid monsoon climate with cold and dry winters and arid and windy spring with an average annual rainfall of 596 millimeters. According to historical data, each year there is a threat of drought. The masses have said that “ten years of nine-year drought” are often delayed by drought in spring and drought for several years in a row. Therefore, I lack of groundwater resources in our area, insufficient groundwater. Generally about 100 meters deep wells, the output of only 20 to 30 meters per hour 3, coupled with continuous drought in recent years, the drastic decline in groundwater level, single-well benefit decreased, energy consumption increased, the pump update and other reasons, every spring Drought, pumping the phenomenon of hanging pump there. According to test analysis, in the dry season every hour to raise water
