Abstract
The utility model provides a with water conservancy diversion righting device in camber, including the body, the body is equipped with the cover of setting upright or straight with water conservancy diversion in the camber outward, the right side of rightting the cover is equipped with stop nut, the device is connected with the sucker rod through the screw thread of body, the sucker rod is in among the oil pipe, because it is bigger than sucker rod collar external diameter to right set external diameter with camber, and adopt same camber, the structure of interior water conservancy diversion, increase its and the inner wall of the oil tubing effective contact area, slow down the rate of wear of sucker rod up -and -down motion in -process to it, and adopt the interior water conservancy diversion hole of particular form's axial flow line type, flow surface amasss the super large, reduce the oil stream resistance and reduce the pulling force to the sucker rod promptly, sucker rod life has been prolonged, and reduced the beam -pumping unit consumption.
Description
Technical field
This utility model relates to a kind of erection device, is specifically related to a kind of with curvature Inner guide erection device.
Background technology
Having in bar oil recovery process, oil pumper drives sucker rod to pump and recovers the oil, and due to the impact of the factors such as oil pumper centering, hole deviation, eccentric wear phenomenon often occurs, causes sucker rod and box cupling to scrap in advance.At present, it is linear contact lay that the Inner guide centralizer of use also exists with oil pipe, and effective contact area is little.Pod apertures is also circular hole, and crude oil area of passage is the most little.The supporting positive cover rate of wear that so certainly will make is fast, sucker rod loads extra increase during moving up and down.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model there are provided the erection device of a kind of same curvature Inner guide, device body is connected with sucker rod by screw thread, sucker rod is in oil pipe, owing to same curvature supporting positive cover external diameter is bigger than rod collar external diameter, and use same curvature, the structure of Inner guide, increase itself and the effective contact area of tube inner wall, slow down the rate of wear to it during sucker rod pumps, and use the axial streamlined Inner guide hole of special shape, area of passage super large, reduce oil flow resistance and i.e. reduce the pulling force to sucker rod, the effective service life extending supporting positive cover, reduce suffered load during sucker rod up and down motion in oil pumping process, and reduce oil pumper power consumption；There is simple in construction, feature easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of with curvature Inner guide erection device, includes body；The supporting positive cover being externally provided with same curvature Inner guide of body；The right side of supporting positive cover is provided with stop nut.
One end that described body is adjacent with supporting positive cover is provided with water conservancy diversion tapering.
Described supporting positive cover uses with tube inner wall with the peach-shaped structure having pod apertures of curvature, and appearance profile is set to the peach-shaped structure with pipe aperture same curvature, and its overall dimensions is more than the box cupling external diameter of sucker rod；Inner guide hole is chevron shape.
Described supporting positive cover uses nylon material, and is coated with hydrophilic compounds.
Described stop nut is provided with water conservancy diversion tapering near one end of supporting positive cover.
The beneficial effects of the utility model:
Compared with prior art, this utility model is owing to using the structure with curvature Inner guide at supporting positive cover, and body and stop nut are provided with water conservancy diversion tapering, increase it and flow through flow area with tube inner wall contact area and its oil, reduce abrasion and oil flow resistance, extend the service life of erection device and sucker rod, and reduce oil pumper power consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is same curvature Inner guide erection device schematic diagram of the present utility model.
Detailed description of the invention
See Fig. 1, a kind of with curvature Inner guide erection device, include body 1, the supporting positive cover 2 being externally provided with same curvature Inner guide of body 1；The right side of supporting positive cover 2 is provided with stop nut 3.
One end that described body 1 is adjacent with supporting positive cover 2 is provided with water conservancy diversion tapering.
Described described supporting positive cover 2 uses with tube inner wall with the peach-shaped structure (seeing Fig. 2) having pod apertures of curvature, and appearance profile is set to the peach-shaped structure with pipe aperture same curvature, and its overall dimensions is more than the box cupling external diameter of sucker rod；Inner guide hole is set to be similar to " people " word shape.
Described supporting positive cover uses nylon material, and is coated with hydrophilic compounds.
Described stop nut is provided with water conservancy diversion tapering near one end of supporting positive cover.
