consultIntegrated rainwater pump station is widely used in urban drainage system. Its main function is that when the rainwater can not be discharged by self-flow or the water level is higher than the ground of the drainage area, the rainwater pump station provides transportation power to collect the rainwater and transport it to the pipe network, and then take the next processing step.
The pump selection of integrated stormwater pump station still needs to refer to the designed flow and head first. The amount of rainwater discharge is related to the intensity of rainstorm, the duration of rainfall, the catchment area and other factors. The flow rate should be determined reasonably according to the actual situation. The size of the pump head is related to the water level of the inlet side and the water level of the discharge. For the pump station with large variation of inlet and outlet water level, it is necessary to meet the normal operation of pump head and drainage flow within the specified range.
Second is the choice of pump pump set, usually will use the same model. As for the integrated rainwater pumping station, the discharge of both sewage and rainwater requires a larger flow. Therefore, the integrated rainwater pump station should choose the heavy model with the size, otherwise it will cause inconvenience in the operation and management of the station and waste of power.
Then there is the choice of pump type. Generally speaking, integrated stormwater pumping stations are suitable for submersible sewage pumps. Submersible blowdown pump can be submergently operated, and equipped with automatic coupling device, easy to install and maintain. The Denor integrated rainwater pumping station adopts self-grinding series energy-saving submersible pump, which saves 40% electricity. Compared with ordinary submersible pump, Denor integrated rainwater pumping station has larger flow, smoother operation, higher operation efficiency and more energy saving.
