The basic components of the drainage pumping station include: machine room, sump, grille, auxiliary room, and generally a substation is attached. The water pump unit and related auxiliary equipment are arranged in the machine room. The grille and the suction pipe are installed in the sump, and the sump can also adjust the unevenness of the incoming water to a certain extent, so that the pump can work more evenly. The function of the grille is to block the coarse solid impurities in the water to prevent the debris from blocking and damaging the water pump.

Drainage pumping station manufacturers tell you that drainage pumping stations can be divided into midway pumping stations and terminal pumping stations according to their role in the drainage system. The midway pump station is usually set up to avoid burying the main drainage pipe too deeply. The drainage pump station manufacturer tells you that the terminal pump station is to pump the sewage of the whole town or the sewage of industrial enterprises to the sewage treatment plant or to irrigate the farmland or discharge the treated sewage directly into the water body.
The drainage pumping station manufacturer tells you that according to the nature of its drainage, it can generally be divided into sewage (domestic sewage, production sewage) pumping stations, rainwater pumping stations and confluence pumping stations.
The drainage pumping station pumps all the water from the sewer, not only the water quality is poor, but also a lot of impurities are mixed in the water. This is the commonality of the operation of sewage, rainwater, and combined pumping stations, but their respective operating characteristics are also different.
1. Sewage pumping station
Sewage pumping stations generally run all day (small sewage pumping stations also operate part-time), and the number of working pumps should be determined according to changes in water volume. The sump of the sewage pumping station has a certain function of regulating and storing, and the operator of the pumping station can control the start and stop of the pump according to the water level of the sump.
The manufacturer of the drainage pump station tells you that the centrifugal pump is often used because the sewage pump station requires a small flow and a high lift. For some large-scale delivery pumping stations, which require larger flow rates, mixed-flow pumps are often used.
2. Stormwater Pumping Station
The rainwater pumping station must decide the number and size of the pumps to be started according to the rainfall. The water pump requires a large flow and a low head, usually a submersible axial flow pump or a mixed flow pump is used.
3. Confluence Pumping Station
The confluence pumping station is also called the interception pumping station. Due to the different interception facilities, the interception method adopted is also different, and its operation mode and technological process are also different. The interception pumping station has two forms of interception before the pump and interception after the pump.
The drainage pump station manufacturer tells you that the front-pump interception pump station refers to the pump station that discharges the dry flow sewage within the service area into the connecting pipe by gravity flow on the inlet pipe of the pump station. The pumping station where the flowing sewage is directly discharged to the connecting pipe. The manufacturer of the drainage pumping station tells you that the confluence pumping station not only undertakes the daily sewage transportation, but also undertakes flood control discharge. It has the operation characteristics of the sewage pumping station and the rainwater pumping station. The manufacturer of the drainage pump station tells you that the interception facility of the pump station is always located in the grid well in front of the collection pool of the pump station, and the interception facility of the pump station after the pump is located in the back gate well of the outlet well of the pump station. In addition, the confluence pump station must be approved by the central control room before the rainwater pump is turned on.
