...They are used when the difference in height (called head) between the water level at the inlet to the iron pipe and the water level in the outlet channel where the water from the wheel flows is large and the flow rate is relatively small, and are generally used for heads of several hundred meters. Impulse wheels were invented by PS Girard of France in the mid-19th century, and were later improved by Lester Alle Pelton (1829-1908) of the United States, who produced the current model with a water receiver consisting of two bowls attached side by side in 1870. The Pelton wheel has the advantage that the jet of water that hits the water receiver splits into left and right and flows out, resulting in stable performance and high efficiency, as well as a simple structure, and is widely used in the Alps and other areas of Europe. ... *Some of the terminology that mentions "Pelton, LA" is listed below.

…鉄管への水の取入口の水面と,水車から出た水を流す放水路水面との高さの差(落差という)が大きく,流量が比較的少ない場合に用いられ,一般には数百mの落差に使用されることが多い。 衝動水車は19世紀中ごろフランスのP.S.ジラールにより発明されたが,その後アメリカのペルトンLester Alle Pelton(1829‐1908)により改良され,現在用いられているような,二つの椀を並べて取り付けた形の水受けをもつものが1870年に製作された。ペルトン水車は水受けに当たった噴流が左右に分かれて流出するので,安定した性能で高い効率がえられ,しかも構造が簡単であるという利点があり,ヨーロッパのアルプス地方などで多く用いられている。… ※「Pelton,L.A.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
