Integrated rainwater pump station for rainwater collection in low-lying areas of urban areas

Description :

Integrated rainwater lifting pump stationThe characteristic is that there is a significant difference in the designed flow rate between heavy rain and light rain. The selection of integrated rainwater lift pump station pumps should first meet the requirements of large design flow, but also take into account the changes in rainwater runoff. It is not comprehensive to only focus on large flow and ignore small flow, which will bring difficulties to the work of the integrated rainwater lifting pump station. The number of rainwater pumps should generally not be less than 2-3 to adapt to changes in incoming water flow.

　　The integrated rainwater lift pump station has a low head of the axial flow pump, so the pressure pipe should be as short as possible to reduce head loss. The selection of the diameter of the pressure pipe should ensure that the flow velocity and head loss are less than 4% to 5% of the pump head. The outlet of the pressure pipe is not equipped with a gate valve, only a flap valve. The high water level elevation in the collection tank of the integrated rainwater lifting pump station is generally the top elevation of the incoming water main pipe, and the low water level is generally slightly lower than the bottom elevation of the incoming water main pipe. For pump stations with high flow rates, in order to avoid construction difficulties caused by the pump room being too deep, it is also possible to slightly raise the elevation of the bottom of the incoming water pipe channel, so that the low water level is level with the water surface elevation of the water pipe channel under the flow conditions of the pump. The submergence depth of the pump shall be determined according to the specifications of the pump sample.
