Abstract
PURPOSE: To improve productivity and vane wheel efficiency by a method wherein a plurality of vanes to generate diagonal flow acceleration are provided on the surface of the peripheral wall of a conical-trapezoidal hub having a desired diagonal flow angle and each vane is molded integrally by diecasting or the like into a specific shape.
CONSTITUTION: On the peripheral wall surface 1a of a conical-trapezoidal hub 1 having desired diagonal flow angles θ(e.g. 30W60°) a plurality of vanes 2, 2... to generate diagonal flow acceleration are provided at an equal pitch the peripheral direction. Each vane 2 is so constituted that as shown in the figure and when seen from the upper stream the vane sees only end faces of an inlet part 2a and a tip part 2b but not the front part 2c and the rear part 2d. Therefore, the vane wheel A can be molded integrally by injection molding of resin or by die casting of low melting point metal by use of a two-segmental die in the axial direction and productivity can be improved remarkably. Besides, the difference between the outlet and the inlet angle of the vane and the loss of the secondary flow reduce and the efficiency of the vane wheel can be ameliorated.
