Claims (2)
- 遠心式流体機械において,羽根車のシュラウド前縁径をハブ前縁径より大きくし,かつ羽根車を回転軸上流方向である吸込方向から見た場合に,羽根車翼後縁ではシュラウド側をハブ側より回転方向に対し後傾させ,羽根車翼前縁では,羽根車回転中心から径方向に引いた線に対し,羽根車シュラウド側がハブ側より回転方向に対し,同一もしくは前進している遠心羽根車を有することを特徴とする遠心式流体機械。
- 請求項1に記載の遠心式流体機械において,羽根車回転中心を通りかつ羽根車回転軸と平行な平面である子午面と,前記子午面上におけるハブ及びシュラウド各々の前縁から後縁の間において同一比率にあるハブ及びシュラウド上の点をそれぞれ結んだ線とが為す角度であるRake角が,羽根車回転方向を正とした場合に,翼前縁から流れ方向中央までの間で最大値をとると共にそれより下流側では減少し,羽根出口において−5゜〜−35゜となる羽根車を有することを特徴とする遠心式流体機械。
