Integrated precast pump station, water supply and drainage engineering and water engineering field of black science and technology!

With the continuous expansion of the city scale, the discharge of urban sewage is also increasing.

The integrated precast pump station plays an increasingly important role in the process of urban sewage collection and centralized treatment.

The integrated precast pump station is mainly composed of glass steel (or stainless steel) molding cylinder, submersible sewage pump, maintenance platform, escalator, water inlet pipe, water outlet pipe, automatic coupling device, automatic control system, etc.

It is mainly used to collect and discharge sewage and waste water in residential areas, hotels, schools, factories, military barracks and other public places, and mainly adopts buried or semi-buried installation.

Double barrel integrated precast pump station

At present, the integrated prefabricated pump station barrel in the market adopts the single barrel structure, and the fixed bottom of the barrel leads to the pump horn hanging high. The value of hanging height has a significant effect on the flow pattern near the horn. Appropriate hanging height will make the water flow into the horn smoothly and evenly.

When the height of the suspension is small, the water flow into the horn is very poor, resulting in large hydraulic loss, and easy to produce vortex resulting in pump cavitation. When the hanging height is large, the flow velocity at the bottom floor is small, and the water can not be fully absorbed.

Sewage contains a lot of sludge and other impurities, resulting in the bottom of the pump station is easy to accumulate sludge and garbage, not only affect the performance of the pump station will produce odor, cleaning up is very inconvenient, waste a lot of manpower and material resources, maintenance and cleaning costs are high.

Denore integrated precast pump station adopts a well type pump station that can generate preswirl flow. Its technical principle is that the sewage at the bottom of the sewage pool flows into the preswirl basin along the inner ditch of the preswirl basin, and water flows in the same direction as the rotation direction of the pump in the preswirl basin, which can effectively reduce the stop water level of the pump.

And help to clean the sewage and sludge at the bottom of the sewage pool. However, as the pump inlet prespin increases, the amount of rotating ring into the pump increases, which will cause vibration and cavitation of the pump unit.

The rotating cleaning paddle, plasma air deodorizer and exhaust pipe are installed at the bottom of the pump station cylinder. By stirring the rotating cleaning paddle at the bottom, the sludge accumulation is prevented and the odor is eliminated to achieve the self-cleaning effect.
