Definitions

  • a labyrinth seal is generally provided in the space between the casing and the shroud and the space between the casing and the disk to prevent a high-pressure fluid from flowing backward.
  • a mouse labyrinth is provided between the shroud and the casing in the vicinity of the inlet of the closed impeller.
  • the diameter dimension of the pinion gear 3 is set smaller than that of the large diameter gear 103. Therefore, the rotational speed of the rotary shaft 2 having the pinion gear 3 is larger than the rotational speed of the rotary drive shaft 102 having the large diameter gear 103.
  • the rotating shaft 2 is a rotating body formed in a cylindrical shape with the axis O as the center, and is rotated around the axis O by being given a rotational force by the speed increasing transmission unit 200 described above.
  • the positions where these impeller side fins 121 are provided are such that the separation dimension D2 in the radial direction from the axis O to the impeller side fins 121 is 90% or less of the radial dimension D1 of the disk, as in the first embodiment. It is desirable to be.

Abstract

L'invention concerne un compresseur centrifuge (1) qui est pourvu : d'un arbre rotatif (2) s'étendant le long d'un axe (O) ; d'une hélice (5) ayant un disque (7) qui est fixé à l'arbre rotatif (2) et qui fait saillie radialement vers l'extérieur, une pluralité de pales (8) qui sont disposées sur une surface du disque (7) de manière à être espacées de façon périphérique les unes des autres, la surface du disque (7) faisant face à un côté dans la direction de l'axe (O) et un couvercle (9) qui recouvre les lames (8) à partir d'un côté dans la direction de l'axe (O) ; d'un boîtier (6) dont la surface périphérique interne de face (6A) fait face à la surface périphérique externe du couvercle (9) de l'hélice (5) et qui recouvre l'hélice (5). La surface périphérique interne de face (6A) est pourvue : d'une surface périphérique interne cylindrique et circulaire (61A) qui s'étend le long de l'axe (O) ; d'une surface périphérique interne de diamètre agrandi (62A) qui est reliée à l'autre côté, dans la direction de l'axe (O), de la surface périphérique interne cylindrique et circulaire (61A) et qui s'étend radialement vers l'extérieur quand la surface périphérique interne de diamètre agrandi (62A) s'étend vers l'autre côté. Le compresseur centrifuge (1) est pourvu de plus d'une section d'étanchéité (10) qui assure l'étanchéité entre la surface périphérique interne de diamètre agrandi (62A) et la surface périphérique externe du couvercle (9).
