文摘：Q | How does a centrifugal pump work? A centrifugal pump is the most common pump type within the rotodynamic pump family. Centrifugal pumps have a rotating impeller. The liquid enters in line with the shaft and exits the impeller perpendicular(or radial) to the shaft (Image 1, left side). Image 2 is a 180-degree cutaway of a centrifugal pump drawing and shows the impeller enclosed in a casing with inlet and outlet connections. The casing is designed to direct the liquid into the entrance of the impeller and efficiently collects and directs the liquid exiting the impeller into the system piping. The impeller is driven by a shaft, and bearings carry the radial and axial loads. Lastly, there is a dynamic shaft seal that limits leakage along the rotating shaft. It is attached to a shaft that extends through the power frame.
