摘要： A progressing cavity stator and a method for fabricating such a stator are disclosed. Exemplary embodiments of the progressing cavity stator include a plurality of rigid longitudinal stator sections concatenated end-to-end in a stator tube. The stator sections are rotationally aligned so that each of the internal lobes extends in a substantially continuous helix from one end of the stator to the other. The stator further includes an elastomer liner deployed on an inner surface of the concatenated stator sections. Exemplary embodiments of this invention include a comparatively rigid stator having high torque output and are relatively simple and inexpensive to manufacture as compared to prior art rigid stators.

摘要： A hardfacing for downhole progressing cavity pumps is disclosed as well as a method for producing same. The hardfacing consists of a metal carbide layer applied to the ferrous pump rotor body by way of plasma spraying and a top layer of metallic material having a lower hardness than the metal carbide. The metal carbide layer has a grainy surface with a plurality of peaks and intermediate depressions, the peaks being formed by metal carbide grains at the surface of the metal carbide layer. The thickness of the top layer is adjusted such that the depressions between the peaks of the metal carbide layer are completely filled thereby providing the rotor with a metal carbide hardfacing of significantly reduced surface roughness. In the process of the invention, the pump rotor, which may be provided with a molybdenum bonding layer, is plasma coated with the metal carbide and the resulting carbide layer is covered with the metallic material top layer. The top layer is polished either until the dimensions thereof are within the tolerances acceptable for the finished rotor or until a majority of the peaks of the carbide layer are exposed. The hardfacing significantly increases the service life of the rotor and stator of downhole progressing cavity pumps.

摘要： A scroll type fluid displacement apparatus is disclosed in which the scrolls are made of aluminum or an aluminum alloy to reduce the weight of the apparatus. The scrolls are finished by end milling and then electrolytically or chemically polished to reduce the roughness of the mating surfaces. Thereafter, at least one scroll is treated with alumite to reduce wearing due to contact between the scrolls. As a result, sealing of the fluid pockets between the scrolls during extended use of the apparatus can be maintained.

摘要： A progressive cavity pump or motor, particularly suitable for hydrocarbon recovery operations, includes a rotor 20 and a stator 10. Fluid pressure in cavities between the stator and the rotor create torque which rotates the bit. An interior surface of the stator is rigidly secured to the outer housing of the pump stator and defines an interior profile. A substantially uniform thickness elastomeric layer 62 is supported on the outer housing. The pump rotor has an exterior profile which corresponds with the interior profile of the elastomeric layer.

In the mold, a die includes an extrusion unit having a molding space therein and a spiral-shaped extrusion passage provided in the lower portion thereof so as to correspond to a wrap portion disposed in the scroll rotor. A punch is connected to the die to be in close contact with the inner circumference of the molding space and to be able to slide up and down. The lower portion has a shape corresponding to the upper surface of the flange portion of the scroll rotor and a boss portion. The extrusion passage has a land section in direct contact with the extrusion material. The height of a land of the land section varies along the spiral direction.

摘要： An oil rotary vacuum pump of mechanical type is filled with a requested amount of oil at the end of the manufacturing process, then it is stored and then shipped to the user, letting the user avoid an operation of introducing the proper amount of oil into the pump. The oil leakage is prevented by securing the suction and/or exhaust ports of the pump, which are sealed by means of a removable sealing member, for instance by means of a membrane.

摘要： A rotary vane pump is provided that provides an improved fluid replenishment and pressure relief system within a rotary vane pump system. A system, containing a rotary vane pump containing at least one relief cut between the housing and the rotor, functions to relieve fluid pressure normally found between the housing and the rotor. The fluid leaks from areas such as the rotational clearance required between the rotor and an inner wall of the housing. The system includes a reservoir in fluid communication with the relief cut wherein fluid leaks are then retained within the reservoir. A fluid distribution manifold employing a plurality of check valves, each corresponding to a respective chamber within the rotor, provides a controlled fluid feed from the reservoir to the rotor thereby balancing the fluidic pressure existing between the radially innermost ends of the vanes and the radially outermost ends of the vanes.

摘要： Vane pump (10) mechanical losses are reduced by removing vane friction losses and replacing them with lower magnitude journal bearing fluid film viscous drag losses. A freely rotating cam ring (70) is supported by a journal bearing (80). A relatively low sliding velocity is imposed between the cam ring and the vanes (26). This permits the use of less expensive and less brittle materials in the pump by allowing the pump to operate at much higher speeds without concern for exceeding vane tip velocity limits.
