Abstract
The utility model relates to a sucker rod weight increasing module and belongs to the field of oil pumping equipment. Sleeve parts are two semi-cylindrical clamping drums, grooves are horizontally arranged in the clamping drums, and hoops are arranged in the grooves. The sucker rod weight increasing module comprises a coupling part, the coupling part is a hollow cylinder, internal threads are processed in inner rings of two ends of the coupling part, a lead rod is arranged in the cylinder and fixed in the cylinder by welding a fixing piece to the inside of the cylinder, and the weight increasing effect is good.
Description
Technical field
The utility model relates to a kind of sucker rod and increases the weight of assembly, belongs to pumping unit field.
Background technology
Rod string is by some end to end the forming of sucker rod, in oil pumping process, when rod string is up, be raised oil and sucker rod self gravitation and tension, when descending, be subject to oil liquid resistance and pressurized, rod string is tired and lost efficacy under this tension and compression fluctuating load, address this problem at present most employing weighted lever, but this weighted lever diameter is generally 31.45-41.28mm, for heavy oil wells, increases the weight of effect not remarkable.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and increase the weight of effective sucker rod and increase the weight of assembly.
Sucker rod described in the utility model increases the weight of assembly, comprises sleeve member, and sleeve member is two semicircle tubular folder cylinders, and folder cylinder horizontally set groove, establishes clip in groove;
Comprise box cupling part, box cupling part is a hollow cylinder, and two ends inner ring is processed with internal thread, and cylinder interior is established plumbous bar, and plumbous bar is fixed in cylinder by be welded and fixed sheet in cylinder.
Sleeve member end is taper, can reduce oil liquid resistance.
Folder cylinder is outer encloses chute, facilitates the gravel in fluid to pass through, and avoids accumulating in box cupling part place, prevents from stopping up.
Sleeve member and box cupling part Surface Machining quench hardened case, improve case hardness, guarantees inner mechanical performance.
Operating principle and process:
During work, sleeve member is clipped in to sucker rod middle part, with clip, fix, with box cupling part, by screw thread, sucker rod is coupled together, the sleeve member end of taper can reduce oil liquid resistance, if there is gravel in fluid, can from sleeve member sidewall, streak by chute, reduce the scuffing of sleeve member, avoid accumulating of gravel.
The beneficial effect that the utility model compared with prior art had is:
Sucker rod described in the utility model increases the weight of assembly, by sleeve member and box cupling part, increase the overall weight of sucker rod, increase the weight of effective, and use flexibly, convenient disassembly, the sleeve member end of taper can reduce oil liquid resistance, and the chute on sleeve member sidewall can reduce the scuffing of sleeve member, avoids accumulating of gravel.
Accompanying drawing explanation
Fig. 1 is the utility model sleeve member front view;
Fig. 2 is the utility model sleeve member top view;
Fig. 3 is the utility model box cupling part schematic diagram.
In figure: 1, folder cylinder; 2, groove; 3, chute; 4, clip; 5, cylinder; 6, stator; 7, plumbous bar.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1-Figure 3, sucker rod described in the utility model increases the weight of assembly, comprises sleeve member, and sleeve member is two semicircle tubular folder cylinders 1, and folder cylinder 1 horizontally set groove 2, establishes clip 4 in groove 2;
Comprise box cupling part, box cupling part is a hollow cylinder 5, and two ends inner ring is processed with internal thread, and plumbous bar 7 is established in cylinder 5 inside, and plumbous bar 7 is fixed in cylinder 5 by be welded and fixed sheet 6 in cylinder 5.
Sleeve member end is taper, can reduce oil liquid resistance.
Folder cylinder is outer encloses chute 3, facilitates the gravel in fluid to pass through, and avoids accumulating in box cupling part place, prevents from stopping up.
Sleeve member and box cupling part Surface Machining quench hardened case, improve case hardness, guarantees inner mechanical performance.
Operating principle and process:
During work, sleeve member is clipped in to sucker rod middle part, fixing with clip 4, with box cupling part, by screw thread, sucker rod is coupled together, the sleeve member end of taper can reduce oil liquid resistance, if there is gravel in fluid, can from sleeve member sidewall, streak by chute 3, reduce the scuffing of sleeve member, avoid accumulating of gravel.
