摘要： A centrifugal separator has a housing with a generally cylindrical inner surface defining an inner chamber. A hollow rotor is disposed within the chamber for rotation therein. At least one inlet is provided for introducing a liquid mixture into the annular volume between the rotor and the housing, where it is then directed into the rotor. An upper rotor assembly separates the liquid mixture by phase densities with the disparate components directed to respective outlets. In one embodiment of the invention, the upper rotor assembly includes an easily removable weir ring to facilitate "tuning" of the separation process. The rotor of the separator is mounted on a unitary rotor shaft that extends axially through the separation chamber to upper and lower bearing assemblies in the separator housing. The bottom surface of the housing, where the liquid mixture is directed from the annular mixing volume into the rotor, preferably includes a plurality of radial vanes that are curved in the direction of rotation of the rotor to assist in directing the liquid mixture with minimal turbulence. Collector rings for the separated components provided from the upper rotor assembly are preferably formed integrally in the wall of the housing with a smoothly contoured peripheral surface to reduce turbulence of the output streams.

摘要： A centrifugal separator includes a rotor sleeve which reduces the fine scale mixing of liquid components. The rotor sleeve in the annular mixing zone minimizes liquid-liquid shear, but does not adversely affect the pumping action of the rotor. The separator comprises a housing having a generally cylindrical inner surface defining an interior chamber. A hollow rotor is disposed within the chamber for rotation therein, the rotor having upper and lower openings and a generally cylindrical rotor wall with an inner and outer surface. The outer surface of the rotor wall is spaced apart from the inner surface of the housing and thereby defines the annular mixing zone. The rotor sleeve comprises a cylinder only slightly larger than the rotor. The sleeve is fixed relative to the housing, thereby preventing liquid within the annular mixing zone from contacting the rotating outer surface of the rotor. The reduction in mixing action dramatically increases the separation efficiency for shear-sensitive liquid mixtures.
