Abstract
Es wird eine Lagerabdichtung zwischen dem Innenraum einer Zentrifuge und ihrem Antriebsteil vorgeschlagen, bei der drei gleichartige Dichtelemente axial hintereinander angeordnet sind und gegen eine Schutzbüchse der Antriebs welle elastisch andrücken, wobei die Antriebswellen- Schutzbüchse im Andrückbereich des dem Innenraum der Zentrifuge nächstliegenden Dichtelementes einen reduzier ten Durchmesser aufweist, so daß in den Raum zwischen diesem Dichtelement und dem nächstfolgenden Dichtele ment eingeführtes Schutzgas in den Innenraum der Zentrifu ge strömt. There will be a bearing seal between the interior proposed a centrifuge and its drive part, at of the three identical sealing elements axially one behind the other are arranged and against a protective sleeve of the drive Press the shaft elastically, the drive shaft Protective sleeve in the pressure area of the interior of the Centrifuge closest sealing element a reduced has th diameter so that in the space between this sealing element and the next sealing element shielding gas introduced into the interior of the centrifuge streamed.
