In general, the back curved leaves compared with other types of leaves (radial, front curved leaves), compared with the following advantages: First, from the nature of the pressure head, back curved leaves dynamic head in the total head (The total head is equal to the sum of the dynamic head and the static head), so the dynamic head with energy loss accompanying the diffusion part into the static head is also small. Second, the power consumption from the pump point of view, after the curved leaf centrifugal pump in the flow and head changes, the power change is small, so give the motor provides a good working conditions. Third, the internal loss from the impeller point of view, the radial blade and the front curved blade channel is shorter, the diffusion angle and curvature are larger, thus increasing the hydraulic loss. Then the curved leaves on the contrary, less minor losses. Because of this, centrifugal pump blades are used after the song.
