Title (EN) MULTISTAGE CENTRIFUGAL FLUID MACHINE
(FR) MACHINE À FLUIDE CENTRIFUGE À PLUSIEURS ÉTAGES
(JA) 多段遠心流体機械
Abstract:
(EN) Provided is a multistage centrifugal fluid machine with which the work of assembling an inner casing to a high-pressure-side head flange can be carried out efficiently. The multistage centrifugal fluid machine 100 comprises a rotor 3 to which a plurality of impellers (41–81) are attached in the axial direction, a cylindrical outer casing 2, and an inner bundle 1 that fits together with the outer casing 2 to form a flow path for an operating gas. The inner bundle 1 has a high-pressure-side head flange 11, a low-pressure-side head flange 12, and an inner casing 5 arranged between the high-pressure-side head flange 11 and the low-pressure-side head flange 12. The high-pressure-side head flange 11 and the inner casing 5 are fastened to each other with an elastic body 144 therebetween by means of a first bolt 142.
(FR) L'invention concerne une machine à fluide centrifuge à plusieurs étages avec laquelle le travail d'assemblage d'un boîtier interne à une bride de tête côté haute pression peut être réalisé efficacement. La machine à fluide centrifuge à plusieurs étages 100 comprend un rotor 3 auquel sont fixées une pluralité de roues (41- 81) dans la direction axiale, un boîtier externe cylindrique 2, et un faisceau interne 1 qui s'ajuste avec le boîtier externe 2 pour former un trajet d'écoulement pour un gaz de fonctionnement. Le faisceau interne 1 a une bride de tête côté haute pression 11, une bride de tête côté basse pression 12, et un boîtier interne 5 disposé entre la bride de tête côté haute pression 11 et la bride de tête côté basse pression 12. La bride de tête côté haute pression 11 et le boîtier interne 5 sont fixés l'un à l'autre avec un corps élastique 144 entre eux au moyen d'un premier boulon 142.
(JA) 高圧側ヘッドフランジに対するインナーケーシングの組付け作業の効率化を図り得る多段遠心流体機械を提供する。多段遠心流体機械100は、軸方向に複数の羽根車(41~81)が取り付けられたロータ3、円筒形状のアウターケーシング2、及びアウターケーシング2に嵌合し作動流体の流路を形成するインナーバンドル1を備える。インナーバンドル1は、高圧側ヘッドフランジ11、低圧側ヘッドフランジ12、及び高圧側ヘッドフランジ11と低圧側ヘッドフランジ12の間に配されるインナーケーシング5を有し、高圧側ヘッドフランジ11とインナーケーシング5は、弾性体144を介して第1のボルト142にて締結されている。
