Abstract
The utility model discloses a sealing packing of a pumping well polished rod, which comprises a right inclined flap (1), a left inclined flap (2) and connecting nuts (6). The sealing packing of the pumping well polished rod is characterized in that the sealing packing of the pumping well polished rod is in a cylinder structure, an inclined head boss (8) and an inclined head groove (9) on the right inclined flap (1) and the left inclined flap (2) are spliced with each other, a polished rod through hole (4) is arranged in the center of the sealing packing of the pumping well polished rod, four oil storage grooves (5) are arranged at the periphery of the polished rod through hole (4), the connecting nuts (6) are arranged in the center of both ends of the polished rod through hole (4), and an inclined cutter (7) is arranged on the edge. The sealing packing of the pumping well polished rod is convenient to perform an change operation, has good sealing performance and long service life and can be automatically pushed under the action of the spring forces at both sides along with abrasion of a polished rod through hole packing, therefore the packing can be changed without production stop of a pumping well, the production time efficiency is improved, and the oil output is increased.
Description
Technical field
The utility model relates to oil field machinery oil wellhead polish rod seal, particularly is a kind of pumpingh well polished rod seal packing.
Background technology
At present, in the oil field machinery oil manufacturing process, the drive sucker rod that pumps, deep well pump by the pumpingh well polished rod are extracted into ground with crude oil, the sealed packing of pumpingh well polished rod not only requires good sealing, has high abrasion resistance again, and changes conveniently, existing packing adopts loop configuration, must it be cut 30～45 ° of otch clockwise with hacksaw during replacing, and otch staggers 120 °～180 °, need fastening pressure cap to compress the packing radial deformation during packing pine and play sealing function.It is also very inconvenient to change the packing operation, and it is long that oil well stops the well time, influences crude output, and therefore, prior art can not address the above problem preferably.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned weak point, designs a kind of pumpingh well polished rod seal packing, solves the problem of packing poor sealing in the prior art, replacing packing inconvenient operation.
The purpose of this utility model is realized by following technical proposals.
The utility model comprises: right tiltedly lobe, a left side be lobe, attaching nut tiltedly.Its pumpingh well polished rod seal packing is a cylindrical structure, is pegged graft mutually by plagiocephaly boss and plagiocephaly groove on the oblique lobe in the right side, the oblique lobe in a left side, and the center is the polished rod through hole, be provided with four road oil storage tanks around the polished rod through hole, so that the storage grease, lubricated polished rod, the application life of improving packing.The center, two ends is provided with the attaching nut, and limit portion is provided with cuts sth. askew, so that connect with the packing seat.
The beneficial effects of the utility model are: change easy to operately, good seal performance is along with the wearing and tearing of polished rod through hole packing, packing advances under the effect of both sides spring force automatically, and long service life can realize the pumpingh well replacing packing that do not stop production, rate when improving oil well production increases crude output.
Description of drawings
Fig. 1-the utility model master looks and partly cuts open structural representation.
The attached TV structure schematic diagram of Fig. 2-this practicality.
In the accompanying drawing, 1. right tiltedly lobe, the 2. oblique lobe in a left side, 3. seam, 4. polished rod through hole, 5. oil storage tank, 6. the attaching nut 7. cuts sth. askew, 8. plagiocephaly boss, 9. plagiocephaly groove.
The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
Tiltedly lobe 2, attaching nut 6 form pumpingh well polished rod seal packing by the oblique lobe 1 in the right side, a left side.Its pumpingh well polished rod seal packing is a cylindrical structure, pegged graft mutually with plagiocephaly groove 9 by the plagiocephaly boss 8 on the oblique lobe 1 in the right side, the oblique lobe 2 in a left side, the center is a polished rod through hole 4, is provided with four road oil storage tanks 5 around the polished rod through hole 4, the center, two ends is provided with attaching nut 6, and limit portion is provided with cuts sth. askew 7.
