  • Patent number: 8182408
    Abstract: A centrifugal separator includes a rotating centrifuge rotor having a casing which defines an inner separation space. A set of separation discs is provided in the inner separation space. The centrifugal separator includes a torque transmitting part connected to the centrifuge rotor. A drive motor drives the torque transmitting part for rotation of the centrifuge rotor. The drive motor has a first axial end turned towards the centrifuge rotor and a second axial end turned away from the centrifuge rotor. The centrifugal separator includes a stationary frame and a first bearing and a second bearing, which are connected to the frame. The torque transmitting part is rotatably journalled in the first bearing and the second bearing. The first bearing is provided between the drive motor and the centrifuge rotor. The second bearing is provided outside the second axial end of the drive motor.

  • Publication number: 20120040816
    Abstract: The invention relates to a centrifugal separator comprising a casing which delimits and seals off a space in which a rotor is arranged. The rotor forms a separation space which is sealed or isolated from the space, and in which separation space centrifugal separation of a higher density and a lower density component from a fluid takes place. An inlet extends into the rotor for introducing fluid to the separation space, and a first outlet extends from the rotor for discharge of a component separated from the fluid. The space is connected to a pump device which is arranged to remove gas, thereby maintaining negative pressure in said space. The rotor comprises at least one second outlet extending from the separation space to the space for discharge of at least one higher density component separated from the fluid. The invention also relates to a method in such a centrifugal separator.

  • Publication number: 20090186752
    Abstract: The invention refers to a centrifugal separator for centrifuging components contained in a liquid mixture and having different density. A rotating centrifuge rotor is arranged to rotate around a centre axis and comprises a casing defining an inner separation space. An inlet channel is provided for supply of the liquid mixture of components to be separated to the separation space. At least one outlet channel is connected to the separation space and provided for discharge of a component separated during operation. A torque transmitting part around the centre axis is fixedly connected to the centrifuge rotor. A drive motor drives the torque transmitting part and thus the centrifuge rotor in such a way that the centrifuge rotor is brought to rotate. The drive motor comprises a stator and a rotor, which is fixedly connected to the torque transmitting part. The rotor of the drive motor surrounds a cavity which is through-flown by liquid during operation.

  • Publication number: 20080293587
    Abstract: The present invention relates to a method of screening a biological target for transient weak interactions between the target and a library of ligands. The method includes the provision of a composition comprising a biological target and the provision of a plurality of stationary phases from such a composition. A plurality of ligand compositions is transported to the stationary phases to establish contacts between the ligands and the biological targets. Zonal retardation information are collected for each ligand, downstream of the stationary phases in order to select ligands with dissociation constants (Kd) in the range of 0.01 to 10 mM, exhibiting weak affinity to the target.

  • Patent number: 7022163
    Abstract: In a vehicle air is compressed for being used in the brake system of the vehicle, for instance. In the compressor, used for the compression, the air is contaminated with oil and solid particles. In order to be relieved from these particles, before the air is conveyed through a drying filter, the compressed is brought to rotation by means of a rotating member in a centrifugal separator. The rotating member may advantageously include a pile of conical separation discs forming flow passages between each other for the compressed air to be cleaned. By means of an efficient cleaning of the compressed air from particles the life time of the drying filter may be increased.

  • Patent number: 6755896
    Abstract: For cleaning of crankcase gas produced by an internal combustion engine use is made of a centrifugal rotor, that is journalled in a frame through two axially separated bearings. The centrifugal rotor is caused to rotate by use of part of it also as a rotor of an electrical motor. The electrical motor has a stator, which is kept non-rotating and is charged with electric current for rotation of the centrifugal rotor, the centrifugal rotor being kept journalled during its rotation only in the two bearings.

    Abstract: For cleaning of crankcase gas produced by an internal combustion engine use is made of a centrifugal rotor (2), that is journalled in a frame (1) through two axially separated bearings (12, 13). The centrifugal rotor (2) is caused to rotate by use of part of it also as a rotor (19) of an electrical motor. The electrical motor has a stator (18), which is kept non-rotating and is charged with electric current for rotation of the centrifugal rotor (2), the centrifugal rotor (2) being kept journalled during its rotation only in said two bearings (12, 13).
