Abstract
The utility model discloses the combined type packing pad that a kind of oil-field oil pumper uses, be made up of two semicircle pads, the two ends of each semicircle pad have upper brace and lower brace respectively, upper brace offers through hole, lower brace offers screw, two semicircle shim pack synthesis circular gasket, upper brace and the lower brace of two semicircle pads are superimposed together, the through hole of upper brace is corresponding with the screw of lower brace, dormant bolt passes through hole and is screwed onto in screw, and two semicircle pads are fixed together by dormant bolt.The utility model replacement operation is simple and convenient, time saving and energy saving, reduces the labour intensity of employee; Alleviate operation easier, improve safety factor; Shorten downtime, rate when improve well recovery.Due to packing pad system fabricated structure, each part all can be used as standard component local replacing, needs the drawback of integral replacing, saved cost of production when avoiding the wearing and tearing of old-fashioned shim portions.
Description
Technical field
The utility model relates to the combined type packing pad that a kind of oil-field oil pumper uses.
Background technology
Oil recovery factory of current Fuyu County more than 80% oil pumper equipment is all beam pumping unit, and adding packing is one of oil recovery work routine work.Packing pad is at packing box inner bottom part, packing pad causes eccentric wear serious because of all kinds of situation: in rod-pumped well oil recovery process, due to well head partially, horse head rob front or wrong after, the reason such as polished rod is curved, cause pad eccentric wear, cause packing and packing box wearing and tearing, packing adds incessantly, the phenomenons such as the frequent leakage of oil of well head, greatly shortens the life cycle of packing, and impact is normally produced.
Need during normal replacing pad to stop taking out, unload beam hanger for pumping machine and square clamp, generally will shut down 1 ~ 2 hours, and just can be completed by 2 ~ 3 oil recovery works cooperations, not only affect output but also waste time and energy, in the process of dismounting, there is very large potential safety hazard simultaneously.
Summary of the invention
The purpose of this utility model solves existing packing pad to there is the problem changing difficulty, and provide a kind of and change easily quick and reduce the combined type packing pad of cost of production.
The utility model is made up of two semicircle pads, the two ends of each semicircle pad have upper brace and lower brace respectively, upper brace offers through hole, lower brace offers screw, two semicircle shim pack synthesis circular gasket, upper brace and the lower brace of two semicircle pads are superimposed together, and the through hole of upper brace is corresponding with the screw of lower brace, dormant bolt passes through hole and is screwed onto in screw, and two semicircle pads are fixed together by dormant bolt.
When after the utility model wearing and tearing, when needing to change, the utility model is taken apart, again semicircle for the side of wearing and tearing pad is changed into new, during replacing, need not tear polished rod eye and Fang Ka open, the packing pad changing a bite well only needs an oil recovery work just can complete for about 30 minutes, and the time shortens a hours than original, rate when improve oil well production; Due to this novel packing pad system fabricated structure, each part all can be used as standard component local replacing, needs the drawback of integral replacing, saved cost of production when avoiding the wearing and tearing of old-fashioned shim portions.
The beneficial effects of the utility model:
1, the utility model replacement operation is simple and convenient, time saving and energy saving, reduces the labour intensity of employee; Alleviate operation easier, improve safety factor; Shorten downtime, rate when improve well recovery.
2, due to this novel packing pad system fabricated structure, each part all can be used as standard component local replacing, needs the drawback of integral replacing, saved cost of production when avoiding the wearing and tearing of old-fashioned shim portions.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Detailed description of the invention
Refer to shown in Fig. 1, the present embodiment is made up of two semicircle pads 1, the two ends of each semicircle pad 1 have upper brace 11 and lower brace 12 respectively, upper brace 11 offers through hole 13, lower brace 12 offers screw 14, two semicircle pads 1 are combined into circular gasket, upper brace 11 and the lower brace 12 of two semicircle pads 1 are superimposed together, the through hole 13 of upper brace 11 is corresponding with the screw 14 of lower brace 12, dormant bolt 2 passes through hole 13 and is screwed onto in screw 14, two semicircle pads 1 are fixed together by dormant bolt 2.
When after the utility model wearing and tearing, when needing to change, the utility model is taken apart, again semicircle for the side of wearing and tearing pad 1 is changed into new, during replacing, need not tear polished rod eye and Fang Ka open, the packing pad changing a bite well only needs an oil recovery work just can complete for about 30 minutes, and the time shortens a hours than original, rate when improve oil well production; Due to this novel packing pad system fabricated structure, each part all can be used as standard component local replacing, needs the drawback of integral replacing, saved cost of production when avoiding the wearing and tearing of old-fashioned shim portions.
