1. one kind is turned round heterogeneous supercharging oil and gas multiphase flow pump synchronously;

  • Comprise housing (14);

    It is characterized in that;

    Front end bearing support (6), rear end bearing seat (5), oil cylinder (11), rotor (10), slide plate (13), left end cap (18), right end cap (21), eccentric shaft (16), coupling crossover sub (9) and adjustment part are arranged in housing (14), and described adjustment part is made up of key (2), the first adjustment nut (1), the second adjustment nut (4), adjustment cover (3), rear end adjustment nut (23), front end adjustment nut (8);

    Housing (14) forms shoe cream room with front-end bearing pedestal (6) and rear bearing block (5);

    Oil cylinder (11) is connected to form the main transmission axial region with left end cap (18) and right end cap (21) through screw;

    This main transmission axial region is installed on front end bearing support (6) and the rear end bearing seat (5) through tapered roller bearing (17), by rear end adjustment nut (23) and front end adjustment nut (8) location;

    The main transmission axial region is realized the power transmission of coupling (15) and motor through coupling crossover sub (9);

    Eccentric shaft (16) is supported on left end cap (18) and the right end cap (21) through two bearings (7,22) at two ends, forms driven axial region;

    The axis of described main transmission axial region and the axis of driven axial region be not on a center line, but two parallel axis;

    The oil cylinder of main transmission axial region (11) is connected with rotor (10) through slide plate (13) realizes run-in synchronism;

    Rotor (10) is through two pairs of bearings (19;

         20) realize supporting and being positioned on the eccentric shaft (16);

    Balance on having guaranteed axially, eccentric shaft (16) is fixed on rear end bearing seat (5) through the adjustment part and goes up the adjustment that realizes the internal void;

    Main transmission axial region and driven axial region are installed in the cavity of housing (14) and front end bearing support (6) and rear end bearing seat (5) formation, to realize that main transmission axial region and driven transmission axial region are by track run-in synchronism separately;

    And two axis of main transmission axial region and driven axial region are in parastate all the time, have formed a crescent-shaped space between them, and this crescent-shaped space constitutes the active chamber of pump;

    Filler opening is located on the oil cylinder (11) of rotation, in turning course, is communicated with the oil sucting cavity of synchronous rotation all the time;

    Oil extraction gets into eccentric shaft (16) through rotor (10);

    Discharge from the axle head of eccentric shaft (16), oil drain out communicates with oil-drain pipe all the time, continuous completion oil-feed and oil extraction;

    Many row'"'"'s roller bearings (12) are installed, to realize that sliding friction changes rolling friction between rotor (10) and slide plate (13).
