Abstract
A centrifugal separator and pitot pump has a rotor driven in rotation within a casing with fluid to be cleansed of solid material entering a separation chamber of the rotor. Under a rotor imposed, centrifugal force field, solids in the fluid separate from the fluid and exit in a liquid carrier through a pitot tap close to the outer radial rotor wall. Radially interiorly of this tap, a pitot pickup intercepts cleansed production fluid and exits that fluid from the rotor. A head of a scoop of the pitot tap has an inlet in a blunt leading face and a top at the maximum radial limit of the scoop that is relieved from the leading face of the scoop to a trailing end. An inlet passage from the inlet generally parallels the line of the relief. In profile, the leading face of a scoop neck below the head curves in relief from the inlet face to a scoop base and has a relatively large radius of curvature. The leading face of the neck and base in planes normal to a radius from the axis of the rotor presents a blunt surface with curved transition corners between the middle of the face and the sides of the neck and base.
