Process Design of a Large-Scale Intelligent Booster Pump Station for Water Supply
Using a pump station in Guangzhou as an example,this paper elaborated on the process design of a large-scale intermediate booster pump station for water supply.This particular booster station was part of the phase Ⅱ expansion project of the Northern Waterworks in Guangzhou and had a design capacity of 4×104 m3/d.It adopted a combination of"direct pumping+reservoir pumping"for boosting.The pumps selected were horizontally split double-suction centrifugal pumps.To meet the operational requirements of different working conditions,a pump configuration scheme of"large pumps+small pumps"and"power frequency+frequency conversion"was adopted.A clear water tank with a capacity of 1×104 m3 was constructed within the station to ensure stable water supply,and an integrated chlorination unit was installed to maintain water quality in the clear water tank.
