Abstract
The utility model discloses a novel sealing packing of a polish rod of a pumping well, consisting of a right packing (1), a left packing (2) and connecting nuts (6). The novel sealing packing of the polish rod of the pumping well is in a cylinder structure, wherein four groups of inclined bosses (7) and inclined grooves (9) on the V-shaped right packing (1) and the pyramid-shaped left packing (2) are mutually spliced, the center is provided with a polish rod through hole (4), four oil storage troughs (5) are arranged at the periphery of the polish rod through hole (4), the connecting nuts (6) are arranged at the centers of two ends, and the inclined bosses (7) are arranged at the side part. The novel sealing packing of the polish rod of the pump well is convenient to replace and operate and has a good sealing performance. Along with the abrasion of the polish rod and the packing, the packing is automatically advanced under the action of spring force at two sides and has a long service life. The packing can be replaced without stopping production in the pumping well, the production time rate of the pumping well is improved, and the yield of crude oil 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 novel 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.Also have two halves formula special-shaped packing, can not advance automatically after the wearing and tearing, the leakage of oil of seal failure well head causes crude oil loss and contaminated environment.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 novel seal packing.
The purpose of this utility model is realized by following technical proposals.
The utility model comprises: right packing, left packing, attaching nut.Its pumpingh well polished rod novel seal packing is a cylindrical structure, peg graft mutually by four groups of plagiocephaly boss on the right packing of " V " shape, the pyramid left side packing and plagiocephaly groove, the center is the polished rod through hole, be provided with four road oil storage tanks around the polished rod through hole, so that 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 the plagiocephaly boss, 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 and 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.
