Abstract

Die Erfindung betrifft eine Vorrichtung zum Antrieb einer Welle (2). Die Welle (2) dient insbesondere dem Antrieb des Laufrades (3) einer Kreiselpumpe. Auf der Welle (2) ist ein erstes Antriebsteil (11) befestigt. Ein zweites Antriebsteil (10) steht mit dem ersten Antriebsteil (11) in Wirkverbindung. Ein Trennelement (12) kann die Antriebsteile (10, 11) räumlich voneinander separieren. Erfindungsgemäß befindet sich in einem Bereich (15) zwischen den beiden Antriebsteilen (10, 11) ein Fluid (14), das sich zumindest teilweise aus einer ionischen Flüssigkeit zusammensetzt, die magnetische Komponenten aufweist.

The invention relates to a device for driving a shaft (2). The shaft (2) is used in particular to drive the impeller (3) of a centrifugal pump. On the shaft (2) a first drive part (11) is attached. A second drive part (10) is in operative connection with the first drive part (11). A separating element (12) can spatially separate the drive parts (10, 11) from one another. According to the invention, in a region (15) between the two drive parts (10, 11) there is a fluid (14) which at least partially consists of an ionic liquid which has magnetic components.
