Abstract
The utility model relates to a sand scraper oil pump which solves the problems of easy stuck pump, quick abrasion between a pump barrel and a plunger and low pumping efficiency existing in the present plunger oil well pump. The utility model is characterized in that the upper end surface of a plunger (3) is an inclined plane (2), and the plunger (3) is connected with a plug body (7) through a sleeve barrel (4); the plug body (7) has a spiral groove (5) with a through hole (6). The utility model has the characteristics of no easy stuck pump and low rate of the abrasion between the pump barrel and the plunger, which can prolong the service lives of the plunger and the pump barrel.
Description
Technical field:
The utility model relates to oil well pump used in the oil field machinery oil field, the oil well pump of particularly strike-ofing.
Background technique:
Along with the long-term exploitation in oil field, after down-hole pressure drops to a certain degree, just need to adopt mechanical artificial lifting way to recover the oil.The mechanical oil recovery pump has multiple at present, it mainly is plunger oil-well pump, plunger oil-well pump is mainly by pump barrel, plunger, valve etc. is formed up and down, and present plunger oil-well pump is when using the well that sand content is big, oil is thick, sandstone easily enters between plunger and the pump barrel, cause holddown, in the process of lifting oil and oil-feed, because the thick sucker rod that makes of oil lags behind, cause sucker rod, oil pipe eccentric wear, quicken the wearing and tearing of oil well pump, fall end pump efficiency, shorten the cycle of inspection pump, the inspection pump frequency is high, cause a large amount of manpower and materials wastes, labor strength is big, the cost of production height.
The model utility content:
In order to overcome the deficiency that the existing easy holddown of plunger oil-well pump, pump barrel and plunger wear reach the low problem of pump efficiency soon, the utility model provides a kind of oil well pump of strike-ofing, this pump has the advantages that to be difficult for holddown, to reduce the rate of wear of pump barrel and plunger, can prolong the working life of plunger and pump barrel.
The technical solution of the utility model is: a kind of oil well pump of strike-ofing comprises plunger, and the upper-end surface of plunger is the inclined-plane, and plunger links to each other with cock body by sleeve, has the spiral chute of band through hole on the cock body.
The beneficial effect that the utlity model has is: because the upper-end surface of this oil pump plunger piston is the inclined-plane, promptly be processed into interior chamfering, make the plunger Shi Buhui that in pump barrel, moves up and down produce the holddown phenomenon, have the spiral chute of band through hole on the cock body, the sandstone that plunger scrapes off in pump barrel enters the shaft bottom by spiral chute and through hole.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
Accompanying drawing 2 is partial enlarged drawings of A portion among Fig. 1;
Accompanying drawing 3 is plane outspread drawings of parts 7 among Fig. 1.
1-pump barrel among the figure, 2-inclined-plane, 3-plunger, 4-sleeve, 5-spiral chute, 6-through hole, 7-cock body.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with Fig. 2 and shown in Figure 3, a kind of oil well pump of strike-ofing comprises plunger 3, the upper-end surface of plunger 3 is inclined-plane 2, promptly be processed into interior chamfering, make the plunger Shi Buhui that in pump barrel, moves up and down produce the holddown phenomenon, plunger 3 links to each other with cock body 7 by sleeve 4, have the spiral chute 5 of band through hole 6 on the cock body 7, inclined-plane 2 on the plunger 3 flows to through hole 6 with the sandstone that scrapes off by spiral chute 5 in pump barrel 1, make sand grains in the fluid as much as possible along with oil stream flows, avoid entering the plunger 3 of oil well pump and the gap between the pump barrel 1.
Have the rate of wear that is difficult for holddown, reduces pump barrel and plunger owing to use this to scrape the pump oil well pump, can prolong the working life of plunger and pump barrel.
Claims (1)
1, a kind of oil well pump of strike-ofing comprises plunger (3), it is characterized in that: the upper-end surface of plunger (3) is inclined-plane (2), and plunger (3) links to each other with cock body (7) by sleeve (4), has the spiral chute (5) of band through hole (6) on the cock body (7).
