Abstract
The utility model aims to provide a rolling polish-rod centering rod-pumped well wellhead packing box formed by a rolling polish-rod centering device containing rolling parts. The rolling polish-rod centering device replaces the original cylindrical sleeved polish-rod centering device made of organic materials in the packing box to centralize a polish rod, and is contacted with the polish rod by a circle of at least two rolling parts which are embedded in the rolling polish-rod centering device and protruded from a hole circle contour line with the diameter greater than the diameter of the polish rod in the rolling polish-rod centering device, so as to implement the rolling friction between the rolling parts and the polish rod moving up and down and play an efficient deviation-preventing and centering role on the polish rod, therefore, the service life of packing is prolonged. The rolling polish-rod centering device is mounted in the corresponding rod-pumped well wellhead packing box to form the efficient rolling polish-rod centering rod-pumped well wellhead packing box.
Description
Technical field:
The utility model relates to the oil pumping well head packing box, particularly anti-bias, the abrasionproof apparatus field of oil pumping well head polished rod righting equipment, sucker rod down-hole.
Background technology:
In oilfield exploitation oil process, there is rod pumping motor-pumped well well head that an oil pumping well head packing box is all arranged.In the oil pipe with the liquid of pressure mainly by on polished rod, the spiral type packing that is clipped in the packing box to carry out isolating seal with the oil pipe outside.Polished rod is in the middle of Screw disk-seal tube, and Screw disk-seal tube is in the centre of the stuffing-box of packing box, and whether whether polished rod directly has influence on packing on the packing box center line eccentric wear occurs.Want to make polished rod centering in packing box, just need to be in packing box upper end or the upper/lower terminal tubular bush type polish rod lifting device of settling organic material to make come polished rod is carried out centering.Watt bucket operation because polished rod often need to be checked card, the polished rod surface is easily by hacking or air spots, the upper and lower frequent motion in packing box by hacking or the rough polished rod that misaligns, meeting is so that the tubular bush type polish rod lifting device that upper end or upper/lower terminal are settled in packing box quick-wearing very, thereby causes that polished rod further misaligns, packing generation eccentric wear, mouthful leakage of oil in the packing box.Polished rod is scraped and can be bumped packing box when serious, so that the electrodeposited coating on the polished rod scrapes off very soon, affects the application life of polished rod.So, how reducing the friction of polished rod and the upper and lower erection device of packing box, seem extremely important the application life of improving the erection device of upper and lower arrangement in the packing box.
The utility model content:
The purpose of this utility model is to provide a kind of a kind of tumbling-type polished rod centering oil pumping well head packing box that contains the tumbling-type polished rod centering device 1-12 formation of rolling part 1-15, it be will originally settle the polish rod lifting device of the tubular bush type made of organic material in the packing box make tumbling-type polish rod lifting device 1-12 into and come polished rod is carried out righting, it is by in a kind of embedding tumbling-type polished rod centering device 1-12, the number of turns amount that the hole circle outline line 3-1 greater than the polished rod diameter in tumbling-type polish rod lifting device 1-12 protrudes contacts with polished rod more than or equal to 2 rolling part 1-15, thereby realized rolling part 1-15 and upper, rolling friction between the polished rod of lower motion and the centering of polished rod are installed in tumbling-type polish rod lifting device 1-12 and have just formed a kind of tumbling-type polished rod centering oil pumping well head packing box in the corresponding oil pumping well head packing box.
To achieve these goals, the technical solution of the utility model is:
Thereby it has tumbling-type polished rod centering device 1-12 by a kind of hole circle outline line 3-1 greater than the polished rod diameter that embeds in the tumbling-type polished rod centering device 1-12, in tumbling-type polished rod centering device 1-12 and protrudingly contacts rolling friction between the polished rod of having realized rolling part 1-15 and upper and lower motion and the centering of polished rod to tumbling-type polished rod centering device 1-12 direction of axis line one number of turns amount with polished rod greater than the rolling part 1-15 more than 2.The hole circle outline line 3-1 greater than the polished rod diameter of tumbling-type polished rod centering device 1-12 cuts the rolling part 1-15 in being evenly arranged in tumbling-type polished rod centering device 1-12, makes in the space that rolling part 1-15 consists of between the interior circle axial line greater than the hole circle outline line 3-1 of polished rod diameter and tumbling-type polished rod centering device 1-12 of tumbling-type polished rod centering device 1-12, has a partial volume that rolling part 1-15 protrudes.Being in evenly to be milled with on the concentric circles contour above the annulus area of circular upper buckle 2-8, circular lower pinch plate 2-9 settles quantity to roll hole in piece part hole hole 2-4 greater than the round upper buckle rolling part hole 2-2 of the rolling part 1-15 more than 2, round lower pinch plate, roll arrangement rolling part 1-15 in the hole in piece part hole hole 2-4 at round lower pinch plate, seal groove 2-5 at circular lower pinch plate 2-9 is equipped with O-ring seals 2-3, to on circle, buckle 2-8, circular lower pinch plate 2-9 connect with screw 1-10, realize the complete tumbling-type polished rod centering device 1-12 of a cover.
A kind of tumbling-type polished rod centering oil pumping well head packing box, that tumbling-type polish rod lifting device 1-12 is installed in cavity 1-8 under the packing filling letter seat, packing filling letter 1-6 settles a stage clip 1-5 in the bottom, put spiral type packing 1-4 above the stage clip 1-5, press gland 1-2 above the spiral type packing 1-4, gland upper grooves 1-24 is mounted with wearing ring 1-3, internal thread by packing pressure cap 1-1, external screw thread above the packing filling letter seat 1-7 is spun on packing pressure cap 1-1 above the packing filling letter seat 1-7, cavity 1-14 inserts and has packed into the welding short circuit head 1-18 that connects deduction cap 1-16 under the tumbling-type polished rod centering device, and cavity 1-14 under the tumbling-type polish rod lifting device carried out welded seal with the gap that has packed into the welding short circuit head 1-18 that is connected deduction cap 1-16, connect deduction cap internal thread 1-17 and be connected with lower eccentric short circuit head male thread 1-22, so realized a kind of tumbling-type polished rod centering oil pumping well head packing box.
In the process of the downward turn of packing pressure cap 1-1, downward pressure can be passed to gland 1-2 in packing pressure cap 1-1 top, gland 1-2 is pressed on spiral type packing 1-4 in the packing filling letter 1-6, the pressure of stage clip 1-5 in the packing filling letter 1-6 withstands on spiral type packing 1-4 bottom, when the upper and lower two of spiral type packing 1-4 compresses, spiral type packing 1-4 tightly embraces polished rod, thereby reaches the space of sealing polished rod and packing box inner chamber.
The utility model beneficial effect is: 1, the sliding friction between the tubular bush type erection device of original polished rod and organic material making is made into the rolling friction between polished rod and the tumbling-type polish rod lifting device, reduce the friction factor between polished rod and the polish rod lifting device, improved polish rod lifting device application life.2, the application of high performance tumbling-type polish rod lifting device can be avoided polished rod eccentric wear packing and partial grinding packing set box, thereby has reduced the use amount of packing, has alleviated workman's the amount of labour, has prolonged the application life of polished rod.
