Abstract

Bei gleitdichtungsfreien Durchflußzentrifugen ist die von der ortsfesten Anschlußstelle zu der rotierenden Separationseinheit führende Leitung zum Zuführen bzw. Abführen des Fluids relativ großen mechanischen Beanspruchungen ausgesetzt. Die erfindungsgemäße Zentrifuge weist zur Abstützung der Leitung an dem die Separationseinheit tragenden Drehrahmen (1) eine Lagerschale (13) auf, in die eine an der Leitung vorgesehene Gleitbuchse (9) eingesetzt wird. Lagerschale (13) und Gleitbuchse (9) verfügen über sich aufweitende Gleitflächen (11,15), wodurch die Kontaktfläche klein gehalten werden kann. Die Leitung (6) kann als Einmalartikel kostengünstig hergestellt werden, da diese nur die Gleitbuchse (9) des Lagers umfaßt.
