Title (EN) CENTRIFUGAL COMPRESSOR AND MULTISTAGE COMPRESSION DEVICE
(FR) COMPRESSEUR CENTRIFUGE ET DISPOSITIF DE COMPRESSION À ÉTAGES MULTIPLES
(JA) 遠心圧縮機及び多段圧縮装置
Abstract:
(EN) This centrifugal compressor is provided with: a suction valve (12) which is provided on a suction-side flow path (10a) that is a flow path on the suction side of a centrifugal compressor body (13); a bypass flow path (15) which has both ends respectively connected to the front side and the rear side, in the suction-side flow path (10a), of the suction valve (12); and an auxiliary valve (16) which is provided on the bypass flow path (15) and which has a smaller Cv value than the suction valve (12). By using the centrifugal compressor, great pressure loss is assuredly achieved, and thereby, the activation power of the centrifugal compressor can be assuredly reduced.
(FR) L'invention concerne un compresseur centrifuge, comprenant : une soupape d'aspiration (12) prévue sur un trajet d'écoulement (10a) côté aspiration qui est un trajet d'écoulement sur le côté aspiration d'un corps de compresseur centrifuge (13) ; un trajet d'écoulement de dérivation (15) qui a ses deux extrémités respectivement reliées au côté avant et au côté arrière, dans le trajet d'écoulement (10a) côté aspiration, de la soupape d'aspiration (12) ; et une soupape auxiliaire (16) prévue sur le trajet d'écoulement de dérivation (15) et qui présente une valeur Cv inférieure à la soupape d'aspiration (12). En utilisant le compresseur centrifuge, il est possible d'obtenir de manière certaine une grande perte de pression et, ainsi, la puissance d'activation du compresseur centrifuge peut être réduite de manière certaine.
(JA) 遠心圧縮機本体(13)の吸入側の流路である吸入側流路(10a)上に設けられた吸込み弁(12)と、両端が吸入側流路(10a)における吸込み弁(12)の前後にそれぞれ連通するバイパス流路(15)と、バイパス流路(15)上に設けられ、Cv値が吸込み弁(12)よりも小さい補助弁(16)とを備える遠心圧縮機を用いることで、大きな圧損を確実に得ることにより、遠心圧縮機の起動動力を確実に低減することが可能となる。
