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.
