农用抗旱水泵是农田灌溉及排涝时必不可少的提水机械,正确的选购与安装,对于保证机组安全运行、提高抽水效率,具有重要意义。(1)正确选购农用抗旱水泵的类型很多,这里以潜水电泵为例,介绍其选购注意事项。1根据机井井管内径选择水泵的最大外径。选购时不仅要考虑泵能否装入井管内,还要考虑泵装在井下部位不得接触井管内壁,以防泵在运行中产生振动,损坏井管。一般要求泵的最大外径比井管内径小
Agricultural drought pump is indispensable for farmland irrigation and drainage water lifting machinery, the right to buy and install, for ensuring the safe operation of units to improve pumping efficiency, is of great significance. (1) Correct choice of agricultural drought pump type, here to submersible pump, for example, describes the purchase precautions. 1 According to the inner diameter of the machine well pipe to select the maximum diameter of the pump. When purchasing not only to consider whether the pump into the well tube, but also consider the pump installed in the underground parts shall not be in contact with the well wall, to prevent pump vibration during operation, damaged well tube. Generally require the maximum diameter of the pump smaller than the inner diameter of the well
