Is there a booster pump in the community sewage management office?

There will be no booster pump in the sewage pipeline of the community. It is not allowed to install a relay pump on the pipeline, but only through property management to install non-negative pressure water supply facilities for the building, or to build a water tower in the community. The funds for non-negative pressure water supply facilities can be negotiated by the owners' committee and property management, and each owner can raise some funds.

Principle of booster pump.

Fill the booster pump with liquid first, and then start the centrifugal pump. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller due to inertia, and at the same time, the impeller sucks the liquid out of the suction chamber. In this process, the liquid in the impeller flows around the blades.

In the flow around, the liquid exerts a lift on the blade, and in turn, the blade exerts a force on the liquid which is equal in magnitude and opposite in direction. This force does act on the liquid, making the liquid gain energy and flow out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.
