Description
Technical field
The invention belongs to oil well production apparatus field, and in particular to a kind of anti-seizing oil pump.
Background technology
Holddown failure occurs in oil well in process of production, often, and holddown failure refers to that piston is stuck not in barrel
Back and forth movement can be done, or piston cannot be introduced into barrel, and main cause can be divided into two kinds of situations：One is iron filings holddown, in well workover
In operation process, operating worker turns beam hanger or oil pipe using pipe wrench or hydraulic tongs, since it is desired that high torque is turned to screw thread
Dynamic, so being very easy to the iron filings that drop, iron filings are once fallen into oil pipe, can only enter barrel, the joint of barrel is funnel type,
So iron filings will naturally fall in barrel and be stuck in the annular groove on piston；Two be sediment holddown, and sediment can be divided into many
Kind, it is that impurity based on di-iron trioxide drops shaft bottom after casing wall oxidation first, next to that the long-term eccentric wear institute of beam hanger oil pipe
The metal dust of generation, and shaft bottom silt etc..A variety of sediments together enter barrel with fluid, are constantly lifted until ground
Face.When especially stopping well, such as power failure, electrical fault, polished rod break, disconnected bar and intermittent producing well are former during well is stopped
This sediment constantly risen with fluid and iron filings lose the power of rising, and proportion is more than fluid again can sink in barrel naturally
Barrel is blocked, holddown is caused.In addition, the poor designs of barrel external diameter and piston inner diameter only have 70 microns, such design was both met
Higher pump efficiency, moreover it is possible to reduce the coefficient of friction of piston and barrel, but trickle particulate matter can also cause into the gap
Holddown.
It is inextricable in defined lifting tonnage to be accomplished by carrying out beam hanger back-off work when carrying out lifting unfreezing to holddown failure
Industry, beam hanger back-off operation is one of breakneck underground work, there is very big potential safety hazard.In addition, back-off operation can not profit
Draining is carried out with hammering oil discharger, serious environmental pollution and the wasting of resources can be caused.
The content of the invention
The purpose of the present invention is that the defect being directed in above-mentioned technology can guarantee that oil well is normally produced there is provided one kind, and energy
Effectively filter the iron filings and sediment fallen into barrel, it is ensured that pump occurs without holddown failure in production and when stopping well.
To achieve the above object, the technical scheme that solves of the present invention is：A kind of anti-seizing oil pump, including oil pipe, righting section
Hoop, centralizer body, connector, barrel, outer desilting pipe, mariages joint, sleeve pipe, beam hanger, piston, pump seat connection composition, described oil
Pipe is arranged in sleeve pipe, and the lower end of oil pipe is connected to outer dirt sand tube by righting section hoop, and described righting section hoop is internally provided with
Centralizer body, the lower end of righting section hoop is connected by connector and retainer plate with the top of barrel, between barrel and outer dirt sand tube
Lower end be connected to mariages joint, the internal thread of mariages joint lower end is connected to pump seat.
Described barrel is internally provided with piston and beam hanger, and piston face is provided with annular groove, piston and is additionally provided with
Fluid apertures.
It is funnel type above and below described centralizer body, and spacing is equal, direction is symmetrical.
Described outer sand sediment pipe lower end is connected to the external screw thread of mariages joint, and described barrel is connected to the interior of mariages joint
Screw thread.
Piston cap is provided with described beam hanger, piston cap is ring-shaped, its internal diameter is more than beam hanger external diameter, external diameter is less than oil
Bore, and beam hanger is to be flexibly connected through piston cap.
Described connector is connected by retainer plate with barrel top.
The beneficial effects of the invention are as follows：Iron filings and sediment are guided between barrel and outer dirt sand tube using piston cap
In annular space, the normal work of oil well pump can be ensured, iron filings and sediment can be effectively collected again, it is to avoid holddown event is caused
Barrier, so as to extend the service life and oil well repair free period of oil well pump.
Further, the present invention is in transport and handling, and outer sand sediment pipe can effectively protect the barrel of inside without damage.
Brief description of the drawings

Fig. 2, the top view of centralizer body.
Fig. 3, the top view of connector.
In figure：1. the barrel 7. of 2. 5. retainer plate of righting section hoop 3. centralizer body, 4. connector of oil pipe 6. is outer heavy
The pump seat 14- piston caps of 12. annular groove of sand tube 8. mariages joint, 9. sleeve pipe, 10. beam hanger, 11. piston 13.
15. upper liquid hole.
Embodiment
The embodiment of the present invention is specifically described below in conjunction with the accompanying drawings.
As a kind of anti-seizing oil pump shown in Fig. 1-3, including the oil pipe 1 being arranged in sleeve pipe 9, and pass through righting
The piston cap 14 installed on the outer dirt sand tube 7 and beam hanger 10 of the connection of section hoop 2, piston cap can use metal material or plastics and rubber system
Into being provided with four centralizer bodies 3 in the righting section hoop 2 of the described bottom of oil pipe 1 connection, it is make piston 11 placed in the middle same that it, which is acted on,
When, it is also ensured that iron filings and sediment can be passed through；The lower end of righting section hoop 2 is provided with four connectors 4, to be connected
Circle 5, the effect of retainer plate 5 is fixed barrel 6, prevents it from being swung wantonly in the presence of pressure differential, but does not require sealing；Four
Connector 4 ensure that iron filings and sediment can be passed through；The external screw thread of righting section hoop 2 is connected with outer sand sediment pipe 7, outer sand sediment pipe 7
Lower end is connected to the external screw thread of mariages joint 8, and the lower end of barrel 6 is connected to the internal thread of mariages joint 8；Barrel 6 and outer sand sediment pipe 7
Between annular space be used for accommodate iron filings and sediment；The lower end of mariages joint 8 connects pump seat 13.
When 11 tripping in barrel 6 of piston, in the effect of centralizer body 3, piston 11 can smoothly enter barrel 6, without sideslip
Hit barrel mouthful edge.
When oil well is normally produced, piston 11 moves reciprocatingly in barrel 6, is constantly lifted to ground through upper liquid hole 15 by fluid
Face, when having iron filings or sediment is fallen, continues to fall by the space between four centralizer bodies 3, when dropping down onto connector 4,
Continue to fall by space between four connectors, until fall on the outer bottom of sand sediment pipe 7, although annular groove 12 it is also possible to
Into iron filings or sediment, but the possibility entered can be greatly reduced.
Present disclosure is not only limited to cited by embodiment, and those of ordinary skill in the art are said by reading the present invention
Bright book and any equivalent transformation taken technical solution of the present invention, are that the claim of the present invention is covered.
