一、潜水泵的选择 1、扬程高低:所选潜水泵标牌上的扬程应大于或等于实际扬程+(1～2>米+损失扬程(即实际扬程的1/10)。例如,实际扬程为20米高,那么应选潜水泵的扬程为20米+(1～2)米+2米=23～24米。根据这一数字,应选用NQX-25型水泵,不能选用NQX-20型水泵,否则,会因电机阻力太大而被烧坏。 2、水流量多少:水泵安装到井里,要注意水泵的流 First, the choice of submersible pumps 1, the level of head: the head of the selected submersible pump signs should be greater than or equal to the actual head + (1 ~ 2> m + loss head (ie, the actual head of 1/10) 20 meters high, then the submersible pump head should be 20 meters + (1 ~ 2) meters +2 meters = 23 ~ 24 meters. According to this figure, should be used NQX-25 type pump, can not use NQX-20 type pump , Otherwise, will be burned because the motor resistance is too large. 2, the amount of water flow: pump installed into the well, pay attention to the flow of the pump
