Embodiment
The sleeve in oil field, which scrapes instrument, includes spindle tube 1, display pipe 2, upper end cover 3, bottom end cover 4, thrust bearing A5, thrust
Bearing B6, turbine rotor 7 and turbine stator 8.Display pipe 2 is set with spindle tube 1, one end of display pipe 2 is installed by bolt
There is bottom end cover 4；The other end screw thread of display pipe 2 is provided with upper end cover 3.Certain seam is provided between upper end cover 3 and spindle tube 1
Gap.
Shape is spaced on spindle tube 1 in display pipe 2 adjusting sleeve A9 and adjusting sleeve B10, adjusting sleeve A9 and adjusting sleeve are installed
Turbine rotor 7 and turbine stator 8 are provided with by alignment bearing A11 and alignment bearing B12 on spindle tube 1 between B10.Work
During, when mud enters turbine portion, turbine rotor 7 can drive display pipe 2 to rotate.
Pacified on spindle tube 1 between adjusting sleeve A9 and bottom end cover 4 by being slidingly sealed base 13 and being slidingly sealed back-up ring 14
Equipped with rubber seal 1, so as to realize sealing function.Installed on the spindle tube 1 for being slidingly sealed the side of base 13 by screw 16
There is clamping sleeve 17, the axially position for the leading portion of display pipe 2.It is slidingly sealed on the spindle tube 1 of the opposite side of base 13 and thrust is housed
It is provided with bearing A5, the circumference of display pipe 2 corresponding with thrust bearing A5 by clamp-screw 18 and the active interval shape of briquetting 19
Multiple wire brushes 20.Multiple adjustment spring A21 are provided between wire brush 20 and display pipe 2.The effect for adjusting spring A21 is to make
Wire brush 20 radially stretches display pipe 2, to adapt to different oil pipe calibers.
Thrust bearing B6 is housed on the spindle tube 1 between adjusting sleeve B10 and upper end cover 3, it is corresponding with thrust bearing B6 outer
Multiple scrapers 22 are movably installed with by clamp-screw 18 and briquetting 19 on the circumference of package 2.Set between scraper 22 and display pipe 2
There are multiple adjustment spring Bs 23.The effect for adjusting spring B 23 is to make radially the stretching in display pipe 2 of scraper 22, to adapt to difference
Oil pipe caliber, preferably scrape effect so as to reach.
It is provided with the spindle tube 1 of thrust bearing B6 sides and is slidingly sealed component 24；The main shaft of thrust bearing B6 opposite sides
Adjusting sleeve C25 is provided with pipe 1, baffle first 26 is housed on the spindle tube 1 between adjusting sleeve C25 and adjusting sleeve B10；Baffle first 26
Current limiting is set to cover 27 on the spindle tube 1 of side.Baffle first 26 and current limliting set 27 can play a limit to mud in the course of the work
Stream is acted on, it is allowed to have a small amount of slurry liquid to enter thrust bearing B6 parts, to play lubrication.
One end that the sleeve in oil field scrapes tool spindle pipe 1 is provided with external screw thread, and one end of spindle tube 2 is provided with interior spiral shell
Line, the middle part of spindle tube 1 is provided with mud hole 28.Turbine stator 8 is relatively fixed with spindle tube 1, and the sleeve in oil field scrapes work
When having work, when mud enters turbine portion by mud hole 28, turbine rotor 7 drives display pipe 2 to rotate, so as to drive scraper
22 and wire brush 20 rotate；Realized from there through scraper 22 and wire brush 20 to the scraping of oil pipe tube wall and wiper, and then by dirt
Strike off, due to being provided with multiple adjustment spring Bs 23 between scraper 22 and display pipe 2；And set between wire brush 20 and display pipe 2
Be equipped with multiple adjustment spring A21, scraper 22 and wire brush 20 can radially stretching in display pipe 2, so as to be suitable for different
Oil pipe caliber simultaneously reaches and preferably scrapes effect.Nothing can be achieved during being rotated with display pipe 2 in scraper 22 and wire brush 20
Dead angle pipe cleaning, scraping and wiper to oil pipe tube wall carry out that operating efficiency can be effectively improved simultaneously, reduce job costs.Meanwhile,
Because scraper 22 and wire brush 20 are distributed on display pipe 2 respectively, and it is separate, therefore with the spy for being conveniently replaceable maintenance
Point.Solve existing instrument be generally pipe cleaning with brush pipe separate progress, cleaning performance is limited, and scraper on instrument fixation,
The problem of no dead angle scale removal can not be realized.Sleeve in oil field cleaning is particularly suitable for use in use.
