- Abstract:
- This paper introduced the optimization design method for determining the design scale and pump unit configuration of large rainwater pumping stations exemplified by Longyao Dongfang Food City rainwater pumping station in Xingtai. Based on Hongye storm water drainage and low impact development simulation system (HY-SWMM), the hydraulic model of rainwater pipe network was constructed, and the hydraulic calculation was verified by traditional inference method. The water pump configuration compared the schemes such as combination of large and small pumps, start-up at high and low water levels, and the effective water depth of sump with equal and unequal differences. The design scale of a rainwater pumping station with large catchment area calculated by model method was reduced by approximately 20% compared with that calculated by inference method. It is unscientific to simply divide the flow rate of the water pump according to the scale of the pumping station, and start the pump with equal differential water level. It is necessary to use the combination of large and small pumps and start-up with appropriate high water level and unequal differential water level to avoid frequent start-up and stop of the pump.
