    摘要: A random pitch impeller for a fuel pump has number of blades. An incremental angle of the blades is set by the expression: Δθ   i = ( 360 N ) + ( - 1 ) i × Am × sin  ( p 1 × 360 N × i )  cos  ( P 2 × 360 N × i ) , where ΔθI is the incremental angle between the blades, N is the total number of blades (N=2, 3, 5, 7, 11, 13, 17, . . . ), Am is the distribution magnitude of the inter-blade interval (equally divided angle) (0
