Abstract

PURPOSE: To increase a cooling capacity of a pump impeller, by locating spirally fins at an outer wall of the pump impeller.
CONSTITUTION: Fins 12, which are radially distributed and are protrudedly located at an outer wall 4a of a pump impeller 4, are bent in a given bending rate and formed in a spiral. Staged bosses 13, whose end part 13a is formed in a small radius so that the bosses can be superposed with a few fins 12 out of the aforesaid fins 12 being positioned at proper intervals, are also mounted. Shrouds 14 made of a plate metal are formed in a shape being along the top parts of the fins and in such a manner that links them together in the circumferential direction, and perforations 14a, in which the end parts 13a of the staged bosses 13 are fitted, are ditributedly made in the shrouds 14. The shrouds 14 are fitted in the pump impeller 4 through the end parts 13a of the staged bosses 13 and the perforations 14a in such a manner that covers the fins 12, and are fastened in such a manner that caulks the protruding parts of the end parts 13a.
