The centralizer is fixed on sucker rod by speed, when fixed securely, dismounting when it is simple and convenient, improve oil field elasticity sucker rod
The practicability of centralizer, the top of 1 side of centralizer body are fixedly connected with the side for adjusting sleeve 3, adjust 3 inner cavity of sleeve
Side is fixedly connected with one end of adjustment spring 4, the other end of adjustment spring 4 and the adjustable plate 5 positioned at 3 inner cavity of adjusting sleeve
Side is fixedly connected, and the number for adjusting sleeve 3 is set as eight groups, and eight groups of adjusting sleeves 3 interlock equidistant distribution successively from top to bottom
Both sides in 1 outer surface of centralizer body, it is four layers that eight groups of adjusting sleeves 3, which divide, and adjacent two layers adjust sleeve 3 between at
90 ° of angles can make the middle part for having been at oil pipe 9 of centralizer body 1 by the setting for eight groups of adjusting sleeves 3,
The problem of side grinding occurs for sucker rod during long-term use is avoided, the service life of sucker rod is effectively extended, into
One step improves the practicability of the elastic oil pumping rod centering device in the oil field, and the other side of adjustable plate 5 and the one end for adjusting connecting rod 6 are solid
Fixed connection, the other end for adjusting connecting rod 6 run through and extend to adjust the other side outside sleeve 3 and with the inside of ball-type fixture block 7
It is threadedly coupled, the outer surface for adjusting connecting rod 6 is socketed with the internal activity for adjusting sleeve 3, inner cavity and the ball 8 of ball-type fixture block 7
Outer surface is clamped, and the side of 8 outer wall of ball is contacted with the inner wall of oil pipe 9, and the length that ball 8 stretches out ball-type fixture block 7 is that ball 8 is straight
2/3rds of diameter, and the roughness of 8 outer surface of ball is polishing to Ra3.2 μm, the outer surface of ball 8 are interior with ball-type fixture block 7
Matching for being used between chamber is combined into clearance fit, by the restriction for ball 8, avoids centralizer body 1 in long-term use
The problem of casey occurs because entering impurity between ball 8 and ball-type fixture block 7 in the process alleviates outer surface and the oil of ball 8
Abrasion between 9 inner wall of pipe, extends the service life of ball 8, and the top of 1 outer surface of centralizer body is interior with fixes sleeve 10
Portion is fixedly attached, and the outer wall of fixes sleeve 10 is installed with screeding device 11, and screeding device 11 includes scraper plate sleeve 111, is scraped
The bottom end of sleeve-board cylinder 111 is fixedly connected with the outer surface of fixes sleeve 10, the bottom of 111 inner cavity of scraper plate sleeve and scrapes flat spring
112 one end is fixedly connected, and scrapes the bottom of the other end and the scraper plate connecting plate 113 positioned at 111 inner cavity of scraper plate sleeve of flat spring 112
End is fixedly connected, and the top of scraper plate connecting plate 113 is fixedly connected with one end of scraper plate connecting rod 114, the other end of scraper plate connecting rod 114
Run through and extend to the top of scraper plate sleeve 111 and be fixedly connected with the bottom end of annular scraper 115, scrapes the initial of flat spring 112
Length is less than 111 intracavity bottom of scraper plate sleeve to the distance between 113 bottom end of scraper plate connecting plate, and the top of scraper plate connecting rod 114 is equipped with
Screw thread, and between annular scraper 115 by the way of being threadedly coupled, for scraping the setting of 112 initial length of flat spring so that
The state that flat spring 112 has been at compression is scraped, is avoided and is worn because occurring due to annular is caused to be scraped during long-term use
The problem of plate 115 cannot effectively clear up the fouling of 9 inner wall of oil pipe, at the same scraper plate connecting rod 114 and annular scraper 115 it
Between by the way of being threadedly coupled, replaced convenient for the annular scraper 115 to abrasion, reduce the maintenance of screeding device 11 at
This, the top of annular scraper 115 is contacted with the inner wall of oil pipe 9, can be to 9 inner wall of oil pipe by the setting of screeding device 11
Fouling is effectively cleared up, and the fouling for avoiding 9 inner wall of oil pipe is got deeper during use, so as to cause oil pipe
The problem of 9 oil transportation efficiency is lower effectively raises the service life of oil pipe 9 and the oil transportation efficiency of oil pipe 9.
When work, standing screw 2 is threaded in one end of sucker rod by construction personnel, then by 1 bottom of centralizer body
The internal thread in portion is connect with the threaded one end of another sucker rod, and centralizer body 1 is put into the inside of oil pipe 9 later, is being adjusted
The elastic force effect of section spring 4 is lower to push adjusting connecting rod 6 and ball-type fixture block 7 that ball 8 is driven to be contacted with the inner wall of oil pipe 9, while ring
Shape scraper plate 115 acts on lower band in the promotion scraper plate connecting rod 114 for scraping 112 elastic force of flat spring and moves the outside sidesway of 115 outer wall of annular scraper
It is dynamic that it is made to be contacted with the inner wall of oil pipe 9, when sucker rod is in up and down motion, can be adjusted automatically under the action of eight groups of adjusting sleeves 3
Whole centralizer body 1 has been at the middle part of 9 inner cavity of oil pipe.
In conclusion the oil field can be effective by the setting of ball-type fixture block 7 and ball 8 with elastic oil pumping rod centering device
The force of sliding friction reduced between ball 8 and 9 inner wall of oil pipe, extend the service life of idler wheel, at the same ball-type fixture block 7 with adjust
Between section connecting rod 6 by the way of being threadedly coupled, the idler wheel of abrasion can not be replaced by avoiding existing integral structure
The problem of, reduce the maintenance cost of the elastic oil pumping rod centering device in the oil field；It, can be to oil by the setting of screeding device 11
The fouling of 9 inner wall of pipe is effectively cleared up, and the fouling for avoiding 9 inner wall of oil pipe is got deeper during use, to
The problem of oil transportation efficiency of oil pipe 9 is lower is resulted in, the service life of oil pipe 9 and the oil transportation efficiency of oil pipe 9 are effectively raised；
When solving the both sides in existing roller type sucker rod centralizer when idler wheel while the interior contact with oil pipe, rolling is resulted in
Wheel can not roll at all in oil pipe, increase the abrasion of idler wheel and tube inner wall, reduce roller type sucker rod centralizer
Service life, while existing rolling wheel centralizer is all to use integral structure, can not individually be carried out more when idler wheel damages
It changes, improves the cost of maintenance, and the inner wall of oil pipe will appear carbonate crystallization and organic matter during oil well works
The phenomenon that reducing and being precipitated with temperature, and carbonate crystallization object and organic matter washings can all be attached to tube inner wall and oil pumping
The problem of fouling being formed on bar outer wall, reducing oil pipe service life.
