Abstract
The utility model relates to a packing for a sealing device of an oil pumping polished rod in an oil field, which is in a hollow column shape and is made of oil resistant non-metal materials with good elasticity. The inner wall is a wearing resistant lining tightly combined into a whole with an outer layer. A helical cutting penetration line is arranged on the wearing resistant lining, and the figuration of one end of the wearing resistant lining is in a sectional cone shape. Compared with the ordinary packing, the sealing packing has the advantages of improved wearing resistance, reliable sealing, long service life and convenient disassembly and assembly.
Description
The utility model relates to a kind of polished rod seal packing that is used for oil field sucker rod pumping well head sealing, belongs to consumable accessory.
In the pumpingh well manufacturing process, polished rod sealer is most important to the cleaning at normal operation of pumping unit and scene, and the polished rod seal packing is a quick-wear part important in the polished rod seal, and the quality of its performance directly influences sealing performance and application life.At present the polished rod seal packing of using is generally a plurality of oil resistant rubber packing rings and is formed by stacking, and other oil resistant nonmetals of the usefulness that also has are made, the shape difference, in actual use the life-span all shorter, change frequently or difficult, bring adverse effect to production.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of anti-wear performance good, reliability height, long service life and change oil pumping polish rod sealed packing easily.
Technical solution of the present utility model is achieved in that the sealing packing is hollow cylindrical, is made by rubber-like oil resistant nonmetals, and internal layer is an anti-wearing liner, and combines closely with skin and to be integral.Make the helical form cuting out line on the sealed packing, and one end profile is frustoconical.
Below in conjunction with embodiment of description of drawings.
Among the figure: (1) is the sealed packing skin, is made by the high-quality oil resistant rubber, and (2) are wear-resistant sleeve, system is added with the high-quality oil resistant rubber of wear-resistant material, and the two sulfuration is in aggregates, and the helical form cuting out line is arranged on it, one end profile of packing is frustoconical, cooperates with respective face in the packing box.
The utility model is compared with existing similar sealed packing, and anti-wear performance improves a lot, and sealing is reliable, and mounting or dismounting are convenient, reduced maintenance load, are suitable for and apply.
Claims (3)
1, a kind of polished rod seal packing is hollow cylindrical, is made by rubber-like oil resistant nonmetals, it is characterized in that internal layer is an anti-wearing liner, and combines closely with skin and to be integral.
2, polished rod seal packing according to claim 1 is characterized in that having the helical form cuting out line on it.
