Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.The element of describing in an accompanying drawing of the present utility model or a kind of mode of execution and feature can combine with element and the feature shown in one or more other accompanying drawing or the mode of execution.Should be noted that for purpose clearly, omitted in accompanying drawing and the explanation and the utility model parts irrelevant, that those of ordinary skills are known and expression and the description of processing.Based on the embodiment in the utility model, those of ordinary skills are not paying the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, a kind of harmomegathus tube plug rotation centering oil well pump, comprise pump barrel 1, be provided with cyclone separator 9, rotor 2, pump barrel thruster 3 and harmomegathus ring 4 in the pump barrel 1 successively, also be provided with upper plug thruster 5, centering plunger body 6, lower plunger thruster 7 and the rotary standing valve 8 of hemisphere in the pump barrel 1 successively.
The utility model is by arranging the harmomegathus ring, and the harmomegathus ring expands when up under the effect of liquid stream, dwindles when descending.Thereby reduce descending resistance, alleviate rod sag and eccentric wear.
Referring to Fig. 2, centering plunger body 6 comprises two with upper plug 60, and the circumference that is provided with between the plunger 60 between 61, two annulus 61 of two annulus is provided with worry beads 62, and worry beads 62 contacts with the inwall of pump barrel 1.Worry beads 62 is preferably 6.
Further, each annulus 61 is provided with the groove that holds worry beads 62, the part of worry beads 62 is arranged in the groove of an annulus 61, a part is arranged in the groove of another annulus 62, remaining part is positioned at outside two grooves, contact with the inwall of pump barrel, the shape of described groove is consistent with the shape of the worry beads that holds 62.Be convenient to the fixing of worry beads like this.
As preferably, connect by screw thread 63 between the plunger 60.
The assembling of centering plunger body: worry beads is placed in the predetermined groove of annulus, two annulus step up worry beads, fall annulus again and are enclosed within on the plunger, and two plungers can be assembled a plurality of continuous plungers and annulus and worry beads successively by being threaded.
The length of pump barrel is 6.5-6.7 rice, preferred 6.6 meters.
Structural feature of the present utility model is that the harmomegathus ring is set, and when plunger was descending, contracting was risen to encircle and dwindled, and the gap of plunger and pump barrel increases, make plunger descending smoothly, when plunger was up, near-zero was reduced in the gap of pump barrel and plunger, increased pumping power, improve pump efficiency, sand control card, antiscale card, long service life.Especially be fit to oil well and be the thin oil well, high moisture, contain sand drain or contain gas well.
The utility model reduces ring and leaks because the rotation of pump barrel makes pump barrel and tube inner wall form the lateral flow liquid film, has improved pump efficiency; And the rotation of pump barrel is guaranteed can not cause eccentric wear with tube inner wall.The centering plunger body contacts with pump barrel inwall point by worry beads, reduces the frictional force of pump barrel and plunger, and the plunger rotation is faster.So, the descending resistance of degraded part plunger has been eliminated liquid hammer power and directed eccentric wear, improves suction force and the pump efficiency of pump.When pump barrel moved up and down, the upper plug thruster was under the effect of pump chamber fluid, and liquid is in rotation status all the time in guarantee to feel relieved plunger body and the pump chamber, has improved prop-carrying capacity, reduces sand card, sand plug.The self structure of the rotary standing valve of hemisphere can guarantee in inclined shaft effectively sealing, non-leakage, and blade and hairbrush can know near sludge again when rotated, minimizing sand card, sand plug and the leakage of wearing and tearing and causing because of sand.
The working principle of each parts of the utility model:
Cyclone separator: cyclone separator is done relative rotatablely moving with the eddy flow bar, and stoste is stirred, and makes stoste
In sand scale be difficult for, solve sand and bury problem.
Rotor: rotor rolls with the eddy flow bar and is connected, again can fast rotational when guaranteeing plunger upward and downward, make liquid stream be decomposed into vertical resistance and rotation horizontal component to the active force of pump barrel, reduced the running resistance of sucker rod and pump barrel, alleviate sucker rod load and crooked eccentric wear.
Pump barrel: as the plunger that moves up and down, enlarged the useful area of plunger, improved the extract ability of pump; Increase simultaneously plunger weight again, increased the descending power of plunger, alleviated rod sag and eccentric wear.Pump barrel length is generally 6.6 meters.
The harmomegathus ring: the harmomegathus ring expands when up under the effect of liquid stream, dwindles when descending.Expansion when up makes that annular space dwindles between pump barrel and oil pipe, reduces leakage; Dwindling when descending reduced descending resistance, alleviates rod sag and eccentric wear.
Pump barrel thruster: do relative rotary motion by liquid stream active force promotion pump barrel and bar, solve directed eccentric wear problem, prolong the working life of pump.
The rotary standing valve of hemisphere: be the rotary standing valve of hemisphere, the cleaning brush of its lower end scrubs clean the ball seat sealing strip, and rotary standing valve contacts with the sealing strip rotation, reduces bump, has eliminated the injury to sealing strip; Employing hemispheric design has increased the pressure-bearing when ball valve is closed, and is difficult for secondary and upsprings and cause liquid leakage, keeps higher pump efficiency, prolongation pump working life.Rotary standing valve is positioned at the bottom of pump barrel.
