Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
As shown in Figure 1, a kind of eccentric abrasion prevention seal pressure is from motion tracking polish rod packing of oil pumping machine box, including packing box 8, described
The inside of packing box 8 is back taper, and packing 7 is equipped with inside it, and packing 7 also forms back taper after dosing in packing box.It is described
The upper outside of packing box 8 is connected with upper pressing cap 5, and the external stability of upper pressing cap 5 has adjustment handle 3, and the top of upper pressing cap 5 is connected with pressure
Cap nut 1, the inwall of the upper pressing cap 5 is provided with step.The top of the packing 7 is equipped with packing briquetting 6, and the bottom of packing briquetting 6 is
The circular arc being engaged with packing 7.The top exterior walls of packing briquetting 6 are provided with boss, and boss is located at the upper of the inwall step of upper pressing cap 5
Portion, and the two is stuck.Spring 4 is equipped with inside the packing briquetting 6, between the top of spring 4 and upper pressing cap nut 1 pressure is provided with
Power bearing 2.
The bottom of the packing box 8 is connected with universal ball 13, and the cavity between the packing box 8 and universal ball 13 is built-in
There are seal device briquetting 9 and seal device packing 10, seal device briquetting 9 is located at the top of seal device packing 10.Outside the universal ball 13
Portion is also associated with seal device locking nut 11, and seal device locking nut 11 is located at the bottom of packing box 8.On the universal ball 13
Portion is provided with universal ball upper pressing cap 12, and the bottom of universal ball 13 is provided with universal joint ball seat 14, and upper pressing cap 12 and universal joint ball seat
14 threaded connections.The bottom of universal joint ball seat 4 is provided with down and connects disk 16, and universal joint ball seat 4 and under connect between disk 16 plane on set
There is O-ring seal, universal joint ball seat 4 can connect horizontal direction movement on disk 16 under, and can be with 360 degree of rotations.Under connect on disk 16
Portion is connected with platen 15, and platen 15 is pressed on the bottom surrounding convex edge of universal joint ball seat 14, under connect between disk 16 and platen 15 lead to
Cross and connect valve snail bolt 17 and connect, universal joint ball seat 14 can be carried out spacing, also cause correction packing box 8 and polished rod concentricity side
Just, install time saving and energy saving, only need to correct once, pressing disc for fixing bolt 17 can be successfully completed, it is ensured that packing box is concentric with polished rod
Degree is good.
The device is rotated down upper pressing cap 5 by adjusting handle 3 in assembling, make the boss on the top of packing briquetting 6 from
The step of the inwall of upper pressing cap 5 is opened, the two is not contacted, such packing briquetting 6 compresses downwards packing 7 in the case where the spring 4 on top is acted on,
Packing is pressed on polished rod.After the long-time of packing 7 is using wearing and tearing, packing briquetting 6 compresses downwards packing 7 so as to protect all the time
Hold sealing.Because the elastic force of spring 4 is acted on, make the packing box adjustment once can maintain seal pressure one to three month, reduce
The frequency of maintenance, also avoids the oil well that workman's adjustment is caused not in time from running bleed phenomenon.It is anti-when 7 serious wear of packing
Only the boss on the top of packing briquetting 6 is contacted with the inwall step of upper pressing cap 5, then upper pressing cap 5 is screwed down, and packing briquetting 6 can be after
It is continuous to play a part of to compress packing.Because the top of upper pressing cap 5 is provided with pressure bearing 2, make to tighten lighter during upper pressing cap 5, mitigation
Labor intensity., from the material that hardness is low, elastic high, wearability is good, compressive deformation is good, it is not necessary to too high sealing for packing 7
Pressure, so that it may reach extraordinary sealing effectiveness.Due to seal pressure it is low, compared with conventional high pressure sealed packing box, can be with
Effectively extend more than 3 times of polished rod service life.Simultaneously as packing 7 is taper, in bottom, abrasion upper back packing can be mended
Fill, during serious wear, be not required to take out packing, directly can dose packing from top, packing_seal materials'use rate 100% is reduced
Cost, also reduces workman's amount of labour.The universal ball 13 of the bottom of packing box 8 can be movable in universal joint ball seat 14, can adjust disk
Root box 8 and polished rod concentricity.Meanwhile, universal joint ball seat 14 can be moved with horizontal direction, as such, it is possible to coordinate 360 degree of tune of polished rod
Section orientation, so as to substantially mitigate polished rod eccentric wear, extends polished rod service life, it is ensured that wellhead sealing is good.
