Abstract

PURPOSE: To make the finish processing of the wave breaking portions of a blade and side plate by assembling the impeller elements with a fan-type main plate material, side plate material and blade; and welding the elements together after collecting them in a shape of a circle.
CONSTITUTION: An imperller is completed by assembling impeller elements 10 having a fan shape from which the impeller is to be formed, with the use of the fan- shaped main plate material 11, fan-shaped side plate material 12 and blade 13, and by collecting the impeller elements 10 to form a circle so that the elements are welded together. The elements 10 are formed by those which are cut out of a block material; precisely molded; and electrolytically processed. Otherwise, they are joined by welding or made by a combination of welding and molding, depending on the size and shape required. Consequently, the conventional method of processing in which the wave breaking portions of the blade and side plate becomes unnecessary, besides the shrinkage of blade width caused by the distortion produced at the time of welding does not occur. Thus, it becomes easier to produce a highly precise impeller for use in high speed rotation.
