Abstract
The utility model relates to an oil filled self-lubricating packing box, comprising a cap, a gland bush, a packing, a grease stock room, a disassembling and assembling bore, an oil channel, a grease cavity, a grease fitting, a packing box and a partition fence. The utility model is characterized in that the oil filled self-lubricating packing box is of a column shaped cylinder structure, the inner part of the packing box of the column shaped cylinder body is provided with the partition fence, the packing, the grease stock room and the gland bush from bottom to the top respectively, the inner screw of the cap is linked with the upper end of the outer screw of the packing box, which holds down the gland bush and the packing, the grease stock room is in the center of the packing, and the grease fitting is arranged on the gland box which is over against the grease cavity. The utility model has the advantages of the oil filled self-lubricating packing box is simple in structure, convenient in operation, is suitable to various polished rod sealing devices for the rod-pumped well, saving in the labor and time for filling the grease, prolonged in the service life of the packing, improved in control level of the oil well and production time rate, increased in oil production rate, and good in economic benefit.
Description
One, technical field:
The utility model relates to a kind of oiling self-lubricating formula packing box.
Two, background technology:
At present, in the oilfield pumping well manufacturing process, the packing wear out failure has the reason of following several respects: the one, and the oil well height is moisture, and packing can not get lubricating; The 2nd, oil well is intermittently fuel-displaced, the packing unlubricated friction; The 3rd, the long-time natural abrasion of packing and polished rod.In order to reduce the packing wearing and tearing, usually on polished rod with bottle opener or hand coating butter, duration is very short like this, often the packing wear out failure causes well head to run oil, pollutes well head and surrounding environment, causes to stop well replacing packing increased frequency, influenced oil well output, increased post workman's workload, also influenced the pumpingh well management development simultaneously, thereby prior art can not address the above problem.
Three, summary of the invention:
The purpose of this utility model designs a kind of oiling self-lubricating formula packing box at above-mentioned weak point exactly.
Above-mentioned purpose is realized by following technical proposals:
The utility model comprises pressure cap, gland, packing, butter storage room, dismounting hole, oil duct, butter chamber, grease nipple, packing box, every orchid, it is characterized in that: described is the cylindrical tube body structure, the internal thread that is equipped with successively from bottom to top in the packing box of cylindrical tube every orchid, packing, butter storage room, gland, pressure cap is connected with the external screw thread of packing box upper end, gland, packing are compressed, the butter storage room is positioned at the packing centre position, on the packing box at place, butter chamber, a grease nipple is housed, is convenient to use the grease gun charging butter.
Butter storage room in the above-mentioned oiling self-lubricating formula packing box is an annular, external diameter is less than the packing box internal diameter, internal orifice dimension is greater than the polished rod diameter, on cylindrical, be provided with the cannelure that section is a semicircle, be provided with six oil ducts in the bottom of cannelure, so that make butter enter lubricated polished rod, be provided with two dismounting holes on last plane.
According to the oiling self-lubricating formula packing box that such scheme is made, simple in structure, easy to operate, be applicable to the various polished rod sealers of rod-pumped well, the filling butter is time saving and energy saving, prolongs packing application life, rate when improving oil well management level and production increases crude output, has good economic benefits.
Four, description of drawings:
The utility model master looks the complete section structural representation.
In the accompanying drawing, the 1-polished rod, the 2-pressure cap, the 3-gland, the 4-packing, 5-butter storage room, 6-dismounting hole, the 7-oil duct, 8-butter chamber, the 9-grease nipple, the 10-packing box, 11-is every orchid.
Five, the specific embodiment:
The utility model comprises pressure cap (2), gland (3), packing (4), butter storage room (5), dismounting hole (6), oil duct (7), butter chamber (8), grease nipple (9), packing box (10), every blue (11), it is characterized in that: described is the cylindrical tube body structure, in the packing box (10) of cylindrical tube, be equipped with successively from bottom to top every blue (11), packing (4), butter storage room (5), gland (3), the internal thread of pressure cap (2) is connected with the external screw thread of packing box (10) upper end, with gland (3), packing (4) compresses, butter storage room (5) is positioned at packing (4) centre position, on the packing box of locating over against butter chamber (8) (10) grease nipple (9) is housed, is convenient to use the grease gun charging butter.
Self-lubricating principle: when with grease gun during from grease nipple (9) filling butter, dismounting hole (6) in the butter storage room (5), oil duct (7), butter chamber (8) and butter storage room (5) and polished rod (1) slit, butter storage room (5) all is full of butter with packing box (10), lubricated thereby make between polished rod (1) and the packing (4), in the long-term production process, because liquid has uniform temperature in the well, friction between polished rod (1) and the packing (4) also produces certain heat, butter is heated gradually and enters oil duct (7), thereby make polished rod (1) play self-lubricating function, as long as regularly annotate butter.
Claims (2)
1, a kind of oiling self-lubricating formula packing box, comprise pressure cap, gland, packing, butter storage room, dismounting hole, oil duct, butter chamber, grease nipple, packing box, every orchid, it is characterized in that: described is the cylindrical tube body structure, the internal thread that is equipped with successively from bottom to top in the packing box of cylindrical tube every orchid, packing, butter storage room, gland, pressure cap is connected with the external screw thread of packing box upper end, gland, packing are compressed, the butter storage room is positioned at the packing centre position, on the packing box at place, butter chamber a grease nipple is housed.
