Abstract

PURPOSE: To improve the hydraulic performance of a waterwheel casing by reducing the collision loss of water current which flows in a parallel stay-vane passage formed between a plural number of stay-vanes interposed between two pieces of annular main plates.
CONSTITUTION: A vortex chamber 2 is formed inside a spiral casing 1, and inside the vortex chamber, a plural number of stay-vanes 3 are arranged, and a stay-vane passage 4 is formed between contiguous stay vanes 3, and inside the stay-vane 3, a plural number of guide vanes 5 are arranged. Between contiguous guide vanes 5, a guide-vane path 6 is formed, and the stay vane 3 described above is jammed by two pieces of annular main plate 10 opposed, and thus, a whole speed ring 11 is formed. The inside opposed surface 12 of the annular main plate 10 is so constituted that the width H in the direction of the height along the radial direction of the stay vane path 4 gradually increases in a straight line towards the outer peripheral part
