Title (EN) INDUCER, AND INDUCER-EQUIPPED PUMP
(FR) AUBAGE D'ALIMENTATION ET POMPE EQUIPEE DE CE DERNIER
(JA) インデューサ及びインデューサ付ポンプ
Abstract: front page image
(EN)An axial flow type or diagonal flow type inducer (3) disposed upstream of a main impeller (2) in order to improve the suction performance in a pump, such as a turbo pump. In the inducer (3), the blade angle (&bgr;bt) extending from a tip (T1) to a hub (H1) at a blade front edge (31) is substantially equal to the inlet flow angle (&bgr;1 - t) in the design point flow rate.
(FR)Aubage d'alimentation (3) à écoulement axial ou diagonal situé en amont d'une roue principale (2), dans le but d'améliorer les capacités d'aspiration d'une pompe, telle qu'une turbopompe. Dans cet aubage d'alimentation (3), l'angle d'aube ($g(b)bt) s'étendant depuis la pointe (T1) jusqu'au moyeu (H1) au niveau de la périphérie avant (31) de l'aube est sensiblement égal à l'angle d'écoulement d'entrée ($g(b)1 - t) du débit ponctuel.
(JA)本発明は、ターボポンプ等のポンプにおいて吸込性能を向上させるために、主羽根車(2)の上流側に配置される軸流型又は斜流型のインデューサ(3)に関するものである。本発明のインデューサ(3)においては、翼前縁(31)におけるチップ(T1)からハブ(H1)にかけての翼角度(βbt)が、設計点流量における入口流れ角(β1−t)と略同一となるように形成されている。
