摘要： A fluid system for a pump, which includes a downhole rotating shaft and bearings inside a housing, and where a fluid volume around shaft is circulated from outside housing through a filter, so that only clean non-abrasive fluid is permitted inside fluid volume pump to draw fluid around the shaft. A fluid expeller is included to expel fluid from the accumulated volume of fluid through the filter to purge the filter.

摘要： Disclosed is an apparatus According to the present invention, a new winding arrangement was developed to enhance the manufacturability of stators with large length to diameter ratio and small aperture diameters such as the ones designed and manufactured for downhole pumping applications. The rectangular conductors are pre-formed to a specific shape, nested together, and inserted into the stator slots. Once the conductors are inserted, additional bending and joining operations are required to complete the coils and phases. These operations can be either fully automatic or semi-automatic. The structure of the winding allows insertion of phase and phase to phase insulation after the joining operation is completed thus reducing the risk of damage to the insulation system during the joining process. The pre-formed winding due to its ability to nest by design results is very short end-turns compared to conventional winding

摘要： A stacked stator comprises a plurality of modular components including modular stator elements canned in a cylindrical wall each modular stator being substantially equal in length to a bearing span for the rotor a thin wall longitudinal tube which seals the rotor cavity wherein each modular component abuts the modular component to seal the rotor cavity. The modular components include modular bearing supports. Longitudinal winding slots are provided, having insulating slot liners, which may be extruded.

摘要： A separator for reducing or eliminating the amount of suspending solids from a reservoir fluid of a downhole motor having a rotating seal. The cleaned fluid circulated past the seal and outermost bearing, the separator having a vortex, rotating cyclone or centrifuge, at least one inlet at least one outlet for cleaned fluid, at least one outlet for solid material, water, particulates or similar material separated from the cleaned fluid. The outlet for the clean fluid may include a porous filter.

摘要： A rotor system for a downhole motor comprises a set of permanent magnets, a set of conductors and a pair of end conductor rings connecting the set of conductors. The set of permanent magnets and the set of conductors being substantially coaxial and having the substantially the same linear extent. The set of permanent magnets can be located radially inwards from the set of conductors, and may be provided by discrete conductive bars
