河北省现有配套机井57万多眼,为了贯彻国务院节能指令,落实水电部等部门所发文件的有关精神,自1984年以来,在18个地(市)110多个县开展了以节能节水为中心的机井测试与技术改造工作。截止目前,共测试改造机井20万眼,取得了明显的经济效益。据对24561眼机井测改前后数据统计,装置效率平均由改前的26.7%提高到41.54%,平均提高14.84%;出水量平均由改前的45.15米~3/时增加到62.68米~3/时,单井平均多出水17.53米~3/时,平均出水量增加38.83%。据对电配井19229眼改造前后的统计,千吨米水耗电平均由10.76度降到6.49度,降低4.27度, In order to implement the State Council’s Energy Conservation Directive and implement the spirit of the document issued by the Ministry of Water Resources and other departments, Hebei Province has implemented more than 570,000 well machines. Since 1984, energy-saving projects have been carried out in over 110 counties in 18 prefectures and cities. Water as the center of the well test and technological transformation. Up to now, a total of 200,000 wells have been tested and rebuilt, and obvious economic benefits have been achieved. According to the statistical data before and after the survey of 24561 eye-drilled wells, the average installation efficiency increased from 26.7% to 41.54%, with an average increase of 14.84%; the average amount of water discharged increased from 45.15 m 3 / h to 62.68 m 3 / , The average single well more water 17.53 m ~ 3 / hour, the average water increased 38.83%. According to the statistics of the 19229 electric distribution wells before and after reconstruction, the average power consumption per thousand tons of rice water dropped from 10.76 degrees to 6.49 degrees and decreased by 4.27 degrees,
