I am a student and would like to ask for help from a centrifugal pump designer. What is the definition of the wrap angle of a centrifugal pump? :handshake
If you can't explain it clearly in one or two sentences, I suggest you read other people's papers. [The influence of blade wrap angle on centrifugal pump performance]
For cylindrical blades, can it be considered as the angle between the line connecting the closest point to the axis center and the axis center and the line connecting the axis center to the farthest point? I don’t know if I made it clear or not.
The blade wrap angle is the angle φ formed by the line connecting the inlet of the impeller and the maximum outer diameter of the impeller to the center of the circle, as shown in the figure below. The number of leaves usually used is 5-7. When the number of leaves is small, the wrapping angle should be appropriately increased.
