Abstract:
(EN) A multi-stage centrifugal compressor (100) equipped with: a rotor (2) having impellers (30) provided in multiple stages in the axial direction; diaphragms (60) having a guide flow path (A) that introduces a fluid discharged toward the outside in the radial direction from the impeller (30) to the following-stage adjacent impeller, and a communication hole (70) extending from the base part of the guide flow path (A); a compartment (10a) on the inside of which the multiple diaphragms (60) are housed; and an axial-direction flow path (200) extending so as to connect the multiple communication holes (70). The compartment (10a) has a drain flow path (77) provided only between the communication hole (70) formed closest to an intake nozzle (18) in the axial direction and the communication hole (70) formed closest to a discharge nozzle (19) in the axial direction.
(FR) Un compresseur centrifuge à étages multiples (100) comprend : un rotor (2) ayant des roues (30) situées dans de multiples étages dans la direction axiale ; des diaphragmes (60) ayant un passage de guidage (A) qui introduit un fluide évacué vers l'extérieur dans la direction radiale de la roue (30) à la roue adjacente de l'étage suivant, et un trou de communication (70) s'étendant depuis la partie de base du passage de guidage (A) ; un compartiment (10a) à l'intérieur duquel sont logés les multiples diaphragmes (60) ; et un passage axial (200) s'étendant de façon à relier les multiples trous de communication (70). Le compartiment (10a) a un passage d'évacuation (77) disposé uniquement entre le trou de communication (70) formé le plus près d'une buse d'admission (18) dans la direction axiale et le trou de communication (70) formé le plus près d'une buse d'évacuation (19) dans la direction axiale.
(JA)  この多段遠心圧縮機(100)は、軸線方向に複数段設けられたインペラ(30)を有するロータ(2)と、インペラ(30)から径方向外側に排出される流体を隣接する後段の前記インペラに導入する案内流路(A)、及び案内流路(A)の底部から延びる連通孔(70)を有するダイアフラム(60)と、複数のダイアフラム(60)を内側に収容する車室(10a)と、複数の連通孔(70)を繋ぐように延びている軸線方向流路(200)と、を備えている。車室(10a)は、軸線方向における吸込ノズル(18)に最も近い位置に形成されている連通孔(70)、及び軸線方向における吐出ノズル(19)に最も近い位置に形成されている連通孔(70)との間にのみ設けられるドレン流路(77)と、を有する。
