摘要： In a centrifugal separator for separating a product to a heavy phase and a light phase. The centrifuge rotor encloses a separating space. An inlet channel permits feeding of the product to the separating space. A first outlet channel permits discharge of the heavy phase from the separating space. The second outlet channel permits discharge of the light phase from the separating space. The centrifuge rotor includes a first chamber for collecting the heavy phase, a heavy phase channel, for feeding the heavy phase, and a nozzle member between the heavy phase channel and the first chamber for controlled feeding. The first paring member extends outwardly in the first chamber from the first outlet channel for discharge of the heavy phase. The second paring member extends outwardly in the first chamber.

摘要： In a centrifugal separator a centrifugal rotor is connected to a vertical spindle, which is supported by a frame and journalled in a first bearing and a second bearing. The centrifugal separator is drivable by an electric motor, the stator of the motor being fixed to the frame such that it is radially immovable relative to it, whereas the rotor of the motor is radially movable together with the spindle. The gap between the rotor and the stator of the motor is dimensioned so that it permits the radial movability of the rotor.

摘要： A simple but still effective sealing device to separate two openings (4, 5), which are arranged at a distance from each other in the outer casing (3) of a shaft suspension unit (1), which supports a shaft (2) of a centrifugal separator in a bearing (8, 9), the shaft extending axially through at least one opening (4) into a space surrounding the shaft (2) in the outer casing (3). The sealing device is provided with sealing elements (12, 13), one connected to the outer casing (3) and one connected to the shaft (2), which surround the shaft (2) and divide the space in two departments (15, 16) connected to one opening each (4, 5, respectively). The sealing elements form between themselves a narrow gap (14) surrounding the shaft (2), which prevents the flow of gas between the departments (15, 16). One of the sealing elements (12, 13) has a channel (21), which has an opening (23) in a central part of the gap (14), for the supply of a sealing liquid under pressure to the gap (14) in such a way that oil flows from the opening (23) through the gap (14) and out into the two departments (15, 16).

摘要： An entrainment device for a centrifugal rotor, which is rotatable about a central rotational axis, having a number of entrainment members arranged in said space for entrainment of entering liquid in the rotation of the centrifugal rotor. The entrainment device comprises a first component, which surrounds the rotational axis and has at least one first projection, which has a radial extension, and a second component, which surrounds the rotational axis and has at least a second projection, which also has a radial extension. The second component is axially insertable in said central space to a position, in which said second projection is present adjacent to said first projection. When the entrainment devices are in place in the central space, a locking member is applicable in releasable engagement with said projection so that the second component is prevented from moving axially relative the first component.

摘要： In a particular type of centrifugal rotor for dividing a liquid mixture into one liquid phase having a low viscosity and one concentrate phase having a high viscosity, the concentrate phase on its way towards an outlet chamber (17) in the rotor has to flow through a vortex device (20). The vortex device has a property of admitting therethrough a larger flow of a liquid if this has a high viscosity than if it has a low viscosity. For making an operation for cleaning of the rotor and conduits for concentrate phase downstream of the rotor more efficient, a cleaning liquid, which has a low viscosity, is conducted not only through the vortex device (20) to said outlet chamber (17) for concentrate phase but to this outlet chamber (17) also through a separate passage (34). Thereby, it is guaranteed that a sufficient flow of cleaning liquid enters the concentrate outlet chamber (17) and from there can be pumped out of the rotor to the concentrate phase conduits downstream of the rotor.
