(一)潜水泵的选择 1.潜水泵的扬程应大于实际扬程。即所选潜水泵铭牌上的扬程≥实际扬程+(1～2)米+损失扬程。损失扬程可按实际扬程的1/10估算。例如:实际扬程20米。应选潜水泵的扬
(A) the choice of submersible pumps 1 submersible pump lift should be greater than the actual lift. The selected submersible pump head on the nameplate ≥ actual head + (1 ~ 2) m + loss head. Lost head lift can be estimated based on 1/10 of the actual lift. For example: the actual head of 20 meters. Should be selected submersible pump Yang
