Title:
HYDRAULIC MACHINERY AND OPERATION METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2016070226
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic machinery which expands an opening range that secures self closing features of guide vanes and reduces the hydraulic loss to improve the efficiency.SOLUTION: A hydraulic machinery 1 according to an embodiment includes: a casing 2; stay vanes 3; guide vanes 4; and a runner 6. At least one of the stay vanes 3 has: a vane body part 20; and a downstream side part 21 provided at the downstream side of the vane body part 20. The downstream side part 21 may rotate so as to change an angle of a flow flowing out from the stay vane 3.SELECTED DRAWING: Figure 2
