Description
Technical field
The utility model relates to a kind of auxiliary device in petroleum machinery oil recovery ground installation field, particularly a kind of screw pump sealing load carrier.
Background technique
In oilfield development process, usually adopt sucker-rod pumping.Because operating temperature is high, the oil gas water constituent of stratum extraction is complicated, the leakage of oil-water-gas is caused in oil pumping process, and pressure is also unstable in oil pumping process, particularly due to surface line endure cold, block, the factor such as well-flushing easily causes well head pressure to raise, and causes sucker rod, square clamp to move out of control, causes production accident, be forced to close pumping well, impact is normally produced., still there is a small amount of oil gas water and miss for a long time in general employing mechanical seal or individual pen sealing configuration at present in work, the individual pen sealing configuration that works long hours lost efficacy, and sealing effect is undesirable.
Summary of the invention
Technical problem to be solved in the utility model overcomes the employing mechanical seal that exists in background technique or individual pen sealing configuration sealing effect is bad and well head pressure raises the problem easily causing production accident, and provide a kind of screw pump to seal load carrier, this screw pump sealing load carrier, high pressure resistant, two-way carrying, good sealing effect.
The invention for solving the technical problem reaches by following technological scheme: this screw pump sealing load carrier, and comprise motor, flange major axis, Load-bearing box, motor shaft, motor shaft is built with flange major axis; Flange major axis lower end is fixed on Load-bearing box housing, and on described motor shaft, axle founds end and has been bolted sealing seat; Rapid wear cover is equipped with between flange major axis and sealing seat; Motor shaft top outer wall is equipped with hermetically sealed case; Load-bearing box is equipped with in the external stability of motor shaft lower shaft, motor shaft lower shaft lower end is equipped with plane bearing flange, one direction thrust bearing movable clip block and thrust-bearing successively, plane bearing flange is fixed on motor bottom housing, and high pressure rotary sealing axle is fixedly equipped with in motor shaft lower shaft lower end surface; Motor shaft lower shaft, plane bearing flange, one direction thrust bearing movable clip block and thrust-bearing, high pressure rotary sealing axle are placed in Load-bearing box inside.
The utility model can have following beneficial effect compared with above-mentioned background technology: this screw pump seals load carrier owing to adopting said structure, high pressure resistant, prevents seepage, can reach not leak not ooze an oil dripping aqueous vapor.Seal cage friction pair adopt easily damaged parts mode, and change more convenient, simply, material selection is wear-resistant, anticorrosive material, longer service life.Plane bearing flange and thrust-bearing form Bidirectional bearing structure, can prevent from when polished rod, square clamp High Rotation Speed polished rod moves out of control get rid of curved.
accompanying drawing illustrates:

Accompanying drawing 2 is the structural representations on Fig. 1 motor top;
Accompanying drawing 3 is structural representations of Fig. 1 motor lower portion.
In figure: 1-motor, 2-bolt, 3-seal ring, 4-high pressure rotary sealing axle, 5-plane bearing flange, 6-sealing seat, 7-hermetically sealed case, 8-rapid wear cover, 9-motor shaft, 10-thrust-bearing, 11-oil is stifled, 12-one direction thrust bearing movable clip block, 13-lower shaft, 14-flange major axis, 15-Load-bearing box, 16-drains the oil stifled.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in accompanying drawing 1, Fig. 2, Fig. 3, this oil pumping screw pump direct driving device adopts sealing and load carrier, and comprise motor 1, flange major axis 14, motor shaft 9, motor shaft 9 is built with flange major axis 14; Flange major axis 14 lower end is fixed on Load-bearing box 15 housing; On motor shaft 9, the vertical end of axle is fixed with sealing seat 6 by bolt 2, rotates forward and turns tighter and tighter, structure adopts dual fail-safe method anti-retaining button effectively under adopting left-hand thread screw working state; Be equipped with rapid wear between flange major axis 14 and sealing seat 6 and overlap 8; Motor shaft 9 top outer wall is equipped with hermetically sealed case 7; Between described motor shaft 9 and sealing seat 6, flange major axis 14 and rapid wear be equipped with seal ring 3 between overlapping 8; Load-bearing box 15 is equipped with in motor shaft lower shaft 13 external stability, and radial duct, described Load-bearing box 15 lower end is built with oil stifled 11 and drain the oil stifled 16; Motor shaft lower shaft 13 lower end is equipped with plane bearing flange 5, one direction thrust bearing movable clip block 12 and thrust-bearing 10 successively, and plane bearing flange 5 is fixed on motor 1 bottom shell, and high pressure rotary sealing axle 4 is fixedly equipped with in motor shaft lower shaft 13 lower end surface; It is inner that motor shaft lower shaft 13, plane bearing flange 5, one direction thrust bearing movable clip block 12 and thrust-bearing 10, high pressure rotary sealing axle 4 are placed in Load-bearing box 15; Described seal ring material is teflon, wear-resistant, anticorrosive, longer service life.
