摘要：The invention relates to an apparatus for pumping and conditioning a drillingfluid normally utilized in the drilling, completion or workover of a subterranean oil or gaswell. The apparatus includes a rotor housing encasing a rotatably supported rotorassembly and means for driving the rotor assembly. The rotor assembly is divided intofirst and second chambers. The first chamber has a radial acceleration passage,
connected between an inlet for the drilling fluid and a peripheral portion of the chamber,and means for collecting a first component of the drilling fluid, the drill chips, which arethe heaviest, and are forced to the periphery of the first chamber. The second chamberalso has a radial acceleration passage which is connected between the first chamber and aperipheral portion of the second chamber and has a first pickup means stationarilymounted for collecting a second component, barite, at the periphery of the secondchamber, a second pickup means stationarily mounted for collecting a third component,bentonite, intermediate the periphery and the center of the second chamber, and meansfor collecting a fourth component, gases, at the center of the second chamber. Thebarite and bentonite can then be recycled in the drilling fluid.
