Underground prefabricated sewage lifting pump station

Underground prefabricated sewage lifting pump stationPrinciple:

The liquid level information of the pump station is fed back to the control system by pressure sensors or floating balls, and the water pump switch is adjusted by the operating parameters set by the control system. When the liquid level reaches the system set opening water pump level, the control system will control the water pump to start, so that sewage is pumped from the pump station to the outlet of the municipal sewage pipeline; When the sewage pumping is below the set liquid level of the system, the system will control the water pump to stop. This cycle repeats to ensure the smooth operation of the integrated sewage prefabricated pump station.

The characteristics are continuous water flow, small water flow, but large variation amplitude, and high pollutant content in the water. Therefore, the design of the water collection tank should have sufficient storage capacity and consider backup pumps. In addition, the design should minimize environmental pollution and provide good management and maintenance conditions within the station.

Underground prefabricated sewage lifting pump stationIt consists of a grille room, a water collection tank, a machine room, inlet and outlet pipelines, a transformer and distribution room, a duty room, a tool room, a washroom, and an emergency water outlet. The grille is a steel grille (also known as a trash rack) with certain gaps set at the sewage inlet to intercept debris in the sewage and prevent it from blocking the sewage pump. Mechanical rakes operated manually or automatically by water level control are installed on the grille to regularly or timely remove debris trapped on the grille. The collection tank has both water collection and storage functions to meet the minimum water volume required for starting the sewage pump. The volume of the collection tank is generally not less than the 5-minute output of the largest water pump. The machine room is equipped with sewage pumps, motors, inlet and outlet parts, gates, and other ancillary equipment. Install power transformers and distribution equipment in the substation.
