Claims (11)

  1. Centrifugeuse avec un bol de centrifugation capable de rotation autour d'un axe de rotation, en particulier séparateur avec un bol de centrifugation (2) capable de rotation autour d'un axe de rotation vertical, qui comporte une arrivée (3) pour une matière à centrifuger et au moins deux sorties (10; 12, 13) pour extraire une phase légère et une phase lourde du bol de centrifugation (2) et qui est muni d'une tige d'entraînement (14), la centrifugeuse comprenant un système de rotation isolé de façon hermétique de l'environnement et au moins une diode hydrodynamique montée en aval de l'une des sorties (12, 13) dans le sens d'écoulement, caractérisée en ce que la diode hydrodynamique est conformée comme une chambre de turbulence (18) qui ne tourne pas avec le bol de centrifugation du séparateur pendant le fonctionnement.
  2. Centrifugeuse selon la revendication 1, caractérisée en ce que la chambre de turbulence (18) a une forme cylindrique ou conique.
  3. Centrifugeuse selon la revendication 2, caractérisée en ce que la chambre de turbulence (18) présente une entrée tangentielle (17).
  4. Centrifugeuse selon la revendication 3, caractérisée en ce que la chambre de turbulence (18) présente un écoulement axial (20).
  5. Centrifugeuse selon la revendication 2 ou 3, caractérisée en ce que l'entrée (17) de la chambre de turbulence (18) se situe en aval dans le sens d'écoulement d'un perçage d'écoulement (13) dans la tige d'entraînement (14) de la centrifugeuse.
  6. Centrifugeuse selon l'une des revendications précédentes, caractérisée en ce qu'afin de réaliser une centrifugeuse entièrement hermétique, au moins un dispositif d'étanchéité (5) est disposé dans les zones de transition entre les éléments non rotatifs du tuyau d'arrivée (3) et les éléments rotatifs du bol de centrifugation (2).
  7. Centrifugeuse selon la revendication 6, caractérisée en ce qu'afin de réaliser une centrifugeuse entièrement hermétique, au moins un dispositif d'étanchéité (11, 19) est disposé en outre dans la zone de transition entre chacun des éléments non rotatifs des sorties (11, 13) et les éléments rotatifs du bol de centrifugation (2).
  8. Centrifugeuse selon la revendication 6 ou 7, caractérisée en ce que chaque dispositif d'étanchéité (5, 11, 13) est conformé comme une garniture mécanique d'étanchéité.
  9. Centrifugeuse selon la revendication 6, 7 ou 8, caractérisée en ce que l'un des dispositifs d'étanchéité est disposé entre un perçage d'écoulement (13) dans la tige d'entraînement (14) et l'entrée (17) de la chambre de turbulence (18).
  10. Centrifugeuse selon l'une des revendications 7 à 9, caractérisée en ce que l'un des dispositifs d'étanchéité (5) est disposé entre un tuyau d'arrivée (3) et un distributeur (4) dans le bol de centrifugation (2) rotatif.
  11. Centrifugeuse selon l'une des revendications 7 à 10, caractérisée en ce que l'un des dispositifs d'étanchéité (5) est disposé entre un écoulement (10) et le bol de centrifugation (2).
