A cover-equipped stator for a uniaxial eccentric screw pump is configured such that a condensate liquid accumulated between the outer surface of a stator and the inner surface of the cover when a high-temperature fluid is caused to flow in an inner hole in the stator is discharged to the outside of the cover. The configuration extends the life of the stator and enhances the accuracy of a discharge flow rate. A cover-equipped stator (27) of a uniaxial eccentric screw pump (17) in which a male screw stator (3) is fitted in an inner hole (4a) in a rubber female screw stator (4) and in which a cover (18) is mounted to the outer surface of the stator (4), wherein the cover-equipped stator comprises a first discharge passage (22) for discharging a condensate liquid (15) to the outside of the cover (18). The condensate liquid (15) is a liquid resulting from condensation of water vapor (13) evaporated from a liquid which flows in the inner hole (4a) in the stator (4), transmitted through the stator (4), and condensed and accumulated between the outer surface of the stator (4) and the inner surface of the cover (18). |

PURPOSE: To discharge impurities easily by oil sealing between two overshooting recess grooves formed on the housing side between shaft bearings for supporting rotary shafts of a multi-stage vacuum pump and a housing neck part and the neck part.
CONSTITUTION: A three-lobe type Roots rotor 3 of a multi-stage (two-stage, for example, as illustrated) vacuum pump is fixed to a rotary shaft 4 and contained in a casing 2. A first and a second overshooting recess grooves 6, 16 are formed on the side of a housing 1 between a neck part 5 of the housing 1 installed on a side part of a casing 2 and a shaft bearing 27 for supporting a rotary shaft 4 to communicate with a first and a second drain passages 10, 18. The casing 2 and the drain passage 10 are connected 11 with each other. A first and a second overshooting materials 22, 25 are formed at corresponding parts of the rotary shaft 4 to the recess grooves 6, 16. Oil seals 14, 13 of ethylene tetrafluoride resin are engaged between the overshooting recess grooves 16, 6 and the neck part 5 of the housing 1. Cleaning liquid and impurities mixed in oil can thus be discharged out easily.

An electrical submersible pump system include an electric submersible pump coupled to a lower end of a production conduit extending into a wellbore, the production conduit in fluid communication with a discharge of the electric submersible pump and with a well conduit extending to the surface. A bypass conduit is nested inside the production conduit and is in fluid communication with the discharge. The check valve is opened when flow is established in the annular space and is otherwise closed. The bypass conduit extends for a selected distance above the discharge. The bypass conduit has a plurality of selected diameter apertures through a wall of the bypass conduit to enable flow into the annular space. |

A pump housing includes: a slide surface, along which inner and outer gears are slid; a suction guide passage, which is recessed from the slide surface and guides the fuel at a suction side; a discharge passage, which is recessed from the slide surface-and guides the fuel at a discharge side; and a communication groove, which is recessed from the slide surface and is shaped into an arcuate form that extends along a circumcircle of the inner gear. The communication groove is communicated with the suction groove and the discharge passage through two opposite groove end parts, respectively, of the communication groove. |
