Abstract
The utility model relates to a pumping rod protector. A left half bushing and a right half bushing are buckled on a pump rod body and are fixedly connected into a whole through a garter spring so as to be combined to form a cylinder, a left half centering sleeve and a right half centering sleeve are buckled on the left half bushing and the right half bushing, the two ends of the left half centering sleeve and the right half centering sleeve are provided with threads, an upper fixing sleeve is coupled with the upper parts of the left half centering sleeve and the right half centering sleeve through threads, a lower fixing sleeve is coupled with the lower parts of the left half centering sleeve and the right half centering sleeve through threads, the left half centering sleeve and the right half centering sleeve are sleeved to form a cylinder, and the left half centering sleeve, the right half centering sleeve, the left half bushing and the right half bushing are fixedly connected into a whole. Therefore, the wear of an oil pipe and a pumping rod can be reduced. By adopting the pumping rod protector, the wear of the oil pipe and the pumping rod can be avoided, and the long service life of the centering sleeves can be guaranteed. Since no other force-bearing rods are arranged on the pumping rod column, the problems of breakage and falling can be avoided, and the pumping rod protector has high reliability and good performance in use and can be installed conveniently.
Description
Technical field
The utility model relates to the oil production equipment of petroleum industry, particularly a kind of sucker rod protector.
Background technology
In sucker-rod pumping system, no matter be straight well or inclined shaft, R a T all is relative motion in contact, therefore, exist inevitable wearing and tearing between sucker rod and the oil pipe, particularly deep-well and inclined shaft, sucker rod is easy to bending in oil pipe, serious oil pipe, sucker rod wear problem occur, after the generation wearing and tearing oil pipe and sucker rod can not be used, cause the oil well operation, oil well repair free period is short, increases operating cost, increases rod tube consumption, the oil well off-time is many, has reduced crude output.For avoiding oil pipe, sucker rod wear problems occurring, normal oil pipe, the oil pick-up tube protector of adopting on the oil recovery technique.Existing sucker rod protector kind is more; generally all be to be fixed on the sucker rod; be synchronized with the movement with sucker rod; nonmetals and tube inner wall during oil pumping on the protector are done relative motion, because nonmetals are soft, oil pipe can not wear and tear; played temporary transient protective effect; but the non-metallic material grinding abrasion is very fast, and the time of protection oil pipe, sucker rod is short, and heavy wear still appears in oil pipe, oil pick-up tube.
Summary of the invention
The purpose of this utility model is that design is a kind of both wear-resistant, and the sucker rod protector of do not wear and tear again oil pipe, sucker rod avoids sucker rod sucker rod, oil pipe wear problems to occur in the bending of oil pipe internal cause, inclination.
The purpose of this utility model is achieved in that and comprises fixed cover, garter spring, a left side half lining, right half lining, a left side half supporting positive cover, right half supporting positive cover, following fixed cover, a left side half lining, right half lining spiral-lock is on the sucker rod body of rod, and with garter spring with a left side half lining, right half lining is fixed into one, make left half lining, the synthetic cylinder of right half lining, a left side half supporting positive cover, right half supporting positive cover is buckled in left half lining, on right half lining, a left side half supporting positive cover, there is screw thread at right half supporting positive cover two ends, last fixed cover and left half supporting positive cover, right half supporting positive cover top thread connection, following fixed cover and left half supporting positive cover, right half supporting positive cover lower thread connects, make left half supporting positive cover, the synthetic cylinder of right half supporting positive cover, and with a left side half supporting positive cover, right half supporting positive cover and left half lining, right half lining is fixed into one.
The beneficial effects of the utility model are: the sucker rod protector can slide on the body of rod of sucker rod, and sucker rod has been played good centralizing function, can alleviate the degree of crook of sucker rod in oil pipe, thereby alleviates oil pipe, sucker rod wearing and tearing.Supporting positive cover is wear-resisting soft material, can not damage oil pipe, and during because of the upper and lower motion of sucker rod, the sucker rod protector does not move, and supporting positive cover can not rub on more coarse pipe inner surface and wear and tear, and the supporting positive cover life-span is long.Because left half lining, right half sleeve inner surface are very smooth, though it with sucker rod between relative slip is arranged, also be not easy wearing and tearing.Therefore, the sucker rod protector can guarantee that oil pipe, sucker rod do not wear and tear, and can also guarantee that supporting positive cover has higher application life.Owing to do not increase all the other stressed members on rod string, not existing breaks takes off problem, the reliability height, and easy for installation, functional performance is good.

Fig. 2 is the vertical view after cutting open from A-A among Fig. 1.
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 the utility model embodiment is elaborated.
As shown in Figure 1, 2, first kind of embodiment of the utility model comprises fixed cover 1, garter spring 2, left half lining 3, right half lining 4, left half supporting positive cover 5, right half supporting positive cover 6, following fixed cover 7.Fixed cover 1, following fixed cover 7 internal diameters are a bit larger tham the sucker rod head diameter, to go up fixed cover 1 earlier, following fixed cover 7 is inserted on the sucker rod body of rod from sucker rod head, a left side half lining, right half lining spiral-lock is on the sucker rod body of rod, and with garter spring 2 with a left side half lining, right half lining is fixed into one, make left half lining, the synthetic cylinder of right half lining, make it in use can not cause other accident because of coming off, a left side half supporting positive cover, right half supporting positive cover is buckled in left half lining, on right half lining, a left side half supporting positive cover, there is screw thread at right half supporting positive cover two ends, last fixed cover 1 and left half supporting positive cover, right half supporting positive cover top thread connection, following fixed cover 7 and left half supporting positive cover, right half supporting positive cover lower thread connects, make left half supporting positive cover, the synthetic cylinder of right half supporting positive cover, and with a left side half supporting positive cover, right half supporting positive cover and left half lining, right half lining is fixed into one.A left side half lining, right half lining adopt metal material, and inner surface is very smooth, and the sucker rod protector can slide on the body of rod of sucker rod.During oil pumping, the upper and lower motion of sucker rod, the sucker rod protector does not move, and left half supporting positive cover, right half supporting positive cover are wear-resisting soft material.A left side half supporting positive cover, right half supporting positive cover external surface had oily straight trough or helicla flute.
