Flow-through centrifuge and method for bringing about an operational state of a flow-through centrifuge

A flow-through centrifuge comprising

• a) a stationary housing,
• b) a rotor which is rotated about a rotor axis for centrifugation and to which a medium is supplied during centrifugation and/or from which a medium is discharged during centrifugation,
• c) a connecting strand which is held at one end portion adjacent the stationary housing and which is held at the other end portion adjacent the rotor, so that the two end portions are rotated relative to one another at a first rotational speed, the two end portions being arranged coaxially with respect to the rotor axis of the rotor and the connecting strand serving to supply a medium to the rotor and/or to discharge a medium from the rotor,
• d) a connecting strand guide along or through which the connecting strand extends, the connecting strand guide guiding the connecting strand for passing the rotor on the radial outer side,
• e) a driving arrangement or transmission arrangement comprising a planetary gearset driving the rotor at the first rotational speed and the connecting strand guide at a second rotational speed, the first rotational speed differing from the second rotational speed, the planetary gearset comprising a planetary belt pulley which is rotatably supported on a rotating planet carrier,
• f) a belt which transmits a torque of the planetary belt pulley in the planetary gearset,
• g) a belt tensioning unit supporting the planet carrier, the belt tensioning unit rotating together with the planet carrier and the belt tensioning unit being configured to provide an adjustment of a distance of the planet carrier from the rotor axis.
