1.Determine the design flow of double suction pump:
According to the design flow of double suction pump products corresponding to the selected double suction pump flow rate is greater than the design flow not only less than the design flow.
2.Determine the number and scheme comparison:
On the basis of selection of main pumps pumping station design flow, with the relation i=Q / Q pump station.
3.Determine the design of double suction pump head:
Design head H=H net +h loss. H net for the import and export of water tank design is poor, H loss for the pipeline head loss.
4.To determine the pump type program:
According to pump design flow and design head, to determine whether the choice of double suction pump.
Through the analysis of the selection of the double suction pump, we can know that the most important double suction pump flow and head. This is also the most needed special attention to the selection of places
