Abstract

PURPOSE: To ease the abrupt expansion of flow path on a convex blade side and retard the burble of flow by forming the hub surface of the flow path between blades into such a slant surface that it is further apart from the center of the rotating shaft to the direction from the concave blade side of the guide blade to the convex blade side.
CONSTITUTION: Such a smooth slant surface 6b that it is further apart to the direction from the concave blade side 4b of a guide blade toward the convex blade side 4a is formed on the hub surface 6a of a flow path between blades made up of the guide blades 4, particularly on a surface area from near a place where the hub surface 6a begins to go to the inside in the radial direction to the outlet of the flow path. Thus, the distance between the covex blade side 4a at the cross section C-C', as shown in the upper right drawing, and the shaft center of the concave blade side 4b can be equalized and the curve A of the convex blade side 4a can apprach the curve B of the concave blade side 4b. Accordingly, the abrupt expansion of the flow path on the convex blade side 4a is eased and the burble of the flow is suppressed, permitting a highly efficient guide blade to be obtained.
