许多机电井出水量远远小于水泵铭牌上标的出水量,原因很多,最主要的是水泵安装的实际吸程大于允许吸程。机电井如能合理选型配套、正确安装,可使机电井灌溉面积大幅度增加。一、水泵和机电井配套原则水泵和机电井配套原则是:以井配泵。水泵型号及大小的选用主要是以机电井的出水量,静动水位,井管的口径及动水位离地面的深度等因素来定。
Many electromechanical well water output is much smaller than the pump nameplate water, for many reasons, the most important is the actual installation of the pump suction is greater than the allowable suction. Electromechanical well if properly selected supporting the correct installation, can make the mechanical and electrical well irrigation area increased significantly. First, the principle of matching pumps and electromechanical wells Pumps and electromechanical wells supporting principle is: well with the pump. Pump type and size of the selection is mainly based on the electromechanical well water, hydrostatic water level, well pipe diameter and the water level from the ground depth and other factors to be set.
