农村有不少农业灌溉电机井,因长期使用,出现大量出砂,出水量下降,严重影响了井泵正常运转和单井抽水量,如不加强维护和保养,将会导致电机井报废。我单位机泵技术人员有长期经验积累,总结几点维护保养旧电机井的技术要领。 There are many agricultural irrigation motor wells in rural areas, because of long-term use, there is a lot of sand, water decreased, seriously affecting the normal operation of well pumps and single well pumping, if not to strengthen the maintenance and repair, will lead to motor shaft scrapped. My unit pump technicians have accumulated long-term experience, summed up the technical point of the maintenance of the old motor shaft.
