Description
前記エネルギー回収装置に前記加圧ポンプの回転軸と同軸で前記加圧ポンプの羽根車段数より多い多段のタービン羽根車を有するハイドロタービンを使用し、前記タービン羽根車は前記加圧ポンプのポンプ羽根車と対向するように配置され、前記加圧ポンプの入口側(低圧側)と前記ハイドロタービンの出口側(低圧側)が隣り合うように前記加圧ポンプと前記ハイドロタービンを配置し、前記回転軸の前記加圧ポンプとハイドロタービンの隣り合う位置に回転軸を半径方向に支持する軸受を設けたことを特徴とする。
Ns…ハイドロタービン比速度、N…ハイドロタービン回転速度(rpm)、Q…ハイドロタービン流量(m3/min)、H…有効落差(m)
フランシス式ハイドロタービンにおいては、より高効率が得やすいハイドロタービン設計のためには高比速度化が必要で、ハイドロタービンの羽根車段数をポンプ羽根車段数よりも少なくするとポンプ羽根車よりもより低比速度になり(エネルギー回収とならない)、高効率化のために好ましくないので、少なくとも、ハイドロタービンの羽根車段数をポンプの羽根車段数と同等か又はそれより多く設定する必要がある。
また、軸推力Fは(3)式で計算することができる。
タービン羽根車の段数は、加圧ポンプの羽根車に比べて多いために、タービン羽根車1段当たりの有効落差がポンプ1段当たりの全揚程に比べて小さくなり、同時に、一般的に周速度係数もポンプ羽根車よりも小さいことを考慮すると、タービン羽根車外径はポンプ羽根車外径に比べて小さくなる。したがって、タービン200の軸推力は、(3)式に示すように、(n×H)がタービンとポンプとでほぼ等しいために、タービン羽根車外径が寄与して、ポンプの羽根車外径よりも小さくなる。
