Abstract
The utility model discloses a twisting-fastened type polish rod centering device for a pumping well, and relates to a polish rod centering device used on a pumping well in the petroleum industry. The twisting-fastened type polish rod centering device comprises a column, a centering device body and a through hole, centering wings are equidistantly arranged on the circumference of the column, the polish rod through hole is arranged on the axis of the column, a polish rod transverse cut-in point is arranged in a middle section, a polish rod screw-in opening groove is arranged on one side of an upper section, and another polish rod screw-in opening groove is arranged on the other side of a lower section. The twisting-fastened type polish rod centering device replaces a cylinder made of steel and iron and bearings arranged at two ends of the cylinder. Compared with the prior art, the twisting-fastened type polish rod centering device has the advantages that the twisting-fastened type polish rod centering device is simple in structure and low in production cost, does not have tiny parts, is not damaged easily, and is durable owing to high abrasion resistance of materials of the twisting-fastened type polish rod centering device.
Description
Technical field
The utility model relates in the petroleum industry and to use the polished rod centralizer on the pumpingh well, relates in particular to a kind of cassette pumpingh well polished rod centralizer of turning round.
Background technology
Existing stile comprises: go up catcher, following catcher, drilling rod and righting wheel; Righting wheel is sleeved on the drilling rod; Last catcher and following catcher are located at the upper/lower terminal of drilling rod respectively, and existing righting wheel is the cylinder of ferrous materials and respectively adorns one or more bearings at the two ends of cylinder, is sleeved on drilling rod through bearing; The defective that existing this structure exists mainly contains: heaviness increases labour intensity; Complex structure increases cost of production; Application life is short, gets in the bearing because have a large amount of silt in the work progress, blocks the normal rotation of bearing, and bearing increases the wearing and tearing of drilling rod, and bearing damages easily, maintenance difficult; Easy to wear, bore deeply more, wear phenomenon is obvious more, and effect is set upright in the influence of wearing and tearing back.
Summary of the invention
The utility model is intended to the deficiency that exists in the background technology, and a kind of cassette pumpingh well polished rod centralizer of turning round that provides.
The utility model is turned round cassette pumpingh well polished rod centralizer; By cylinder, set upright the wing and through hole constitutes; Equally spaced be provided with on the circumference of its cylinder and set upright the wing, there is the polished rod through hole in the axle center of cylinder, and the horizontal entry of polished rod is established in the stage casing; Establish polished rod in a side of epimere and be torqued into open slot, also be provided with polished rod at the opposite side of hypomere and be torqued into open slot.
The utility model is turned round cassette pumpingh well polished rod centralizer; Replaced the cylinder of ferrous materials and be located at the bearing at its two ends, compared with prior art, the utility model beneficial effect is: simple on the structure; Cost of production is low; Do not have tiny component, not fragile, the high-wearing feature that material itself has makes durable in use.
Description of drawings
Fig. 1 turns round the structural representation of cassette pumpingh well polished rod centralizer for the utility model.
The specific embodiment
Further specify below in conjunction with 1 pair of the utility model of accompanying drawing;
The utility model is turned round cassette pumpingh well polished rod centralizer; By cylinder 1, set upright the wing 2 and through hole 3 constitutes; Wherein equally spaced be provided with on the circumference of cylinder 1 and set upright the wing 2, there is polished rod through hole 3 in the axle center of cylinder 1, and the horizontal entry 4 of polished rod is established in the stage casing; Establish polished rod in a side of epimere and be torqued into open slot 5, also be provided with polished rod at the opposite side of hypomere and be torqued into open slot 5.
