Abstract
The present invention relates to sealing stuffing for an oil pumping machine in an oil field and a use method thereof. The sealing stuffing comprises polytetrafluoroethylene, fluororubber 2604, graphite powder, aramid fibre, supramoly and No. 3 vulcanizing agents, and a detailed prescription, preparation methods and use methods are disclosed in the specification. The present invention has the advantages that bar-shaped sealing stuffing does not need changing a root. When slight leakage occurs, a handle of an adhesive complementing gun is rotated by a plurality of turns, and stuffing is supplemented to a sealing position of a well head without shutdown. Compared with a rubber root, the sealing stuffing has small frictional resistance and good sealing effect. No matter the sealing stuffing is used in a thick oil well, a rare oil well, a water well and an intermittent well, the sealing effect is better. The sealing stuffing is used in oil pumping machines in oil fields.
Description
Technical field
The present invention relates to filler used in the industrial equipments, specifically, relate to a kind of lock packing of used for oil-field oil pumper, and using method.
Background technology
At present, the oil pumper well head seal box packing in the field produces is revealed when serious, needs to take out old packing, changes the new packing of rubber graphite again, this conventional approach, and both time-consuming, effort has a strong impact on production again.Therefore, it is a kind of simple to be badly in need of development, the effect better products, and fork-like farm tool used in ancient China replaces the well head sealing to change the problem of packing.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, and provide a kind of, under the non-stop-machine state, mend the way of glue toward sealing place of well head tight head in slight leakage.
An object of the present invention is to provide lock packing, be used for sealing place of well head tight head.
Another object of the present invention is the using method of lock packing.
The object of the invention can realize by following measure fork-like farm tool used in ancient China: lock packing comprises that following raw material by weight makes: tetrafluoroethylene 38-42 part, fluororubber 26 0428-32 part, Graphite Powder 99 18-22 part, aramid fiber 4-6 part, molybdenumdisulphide 1-3 part and No. 3 vulcanizing agent 1-3 parts.The preparation method is after Banbury mixer is warming up to 145-155 ℃, feeds intake in Banbury mixer by prescription, and middling speed stirs banburying 1 hour, and the excellent type lock packing through single-screw machine is extruded required specification as required, cuts out unified length specification.
The using method of lock packing: carry out as follows: 1, after tight head and well head install, put into the tapered fibre ring successively, circular fiber wear ring and packing ring, last guide ring, divide the individual filler storehouse of filling, 2, the gas-tight silo upper press cover is screwed, 3, after the upper gland packing filling, colloid-injecting gun must be screwed in the threaded hole on device top, spin-up gum-injecting port jackscrew, in rifle, insert lock packing glue rod, pressure with spiral injects lock packing, 4 in gas-tight silo, start well on the beam, the oil-field oil pumper polished rod is shut down for reciprocal 5-10 time, filling colloid in manual colloid-injecting gun again, restart well on the beam, in the to-and-fro movement of oil-field oil pumper polished rod, filling glue rod is during to good seal, stop filling, 5, in the oil-field oil pumper work 24 hours, answer the close observation leak case, if slight leakage is arranged, inject seal gum more on a small quantity, after having sealed, can reach the service requirements of not revealing for a long time; After operation for some time,, rotate manual colloid-injecting gun, directly replenish small amount of filler glue rod if slight leakage is arranged.

The present invention has following advantage compared to existing technology: excellent type lock packing of the present invention does not need to change packing; if slight leakage is arranged; under non-stop-machine state, rotate a few circle glue gun handles, to well head sealing place additional fillers; get final product; lock packing of the present invention is compared with the rubber packing, and friction resistance is little, good sealing effect; no matter in heavy oil wells, thin oil well, well, go out in the use of well, good sealing effectiveness is all arranged.
Description of drawings
Fig. 1: tight head lock packing utilization structure synoptic diagram of the present invention
Among the figure: 1, oil-field oil pumper polished rod 2, gas-tight silo upper press cover 3 colloid-injecting guns 4 gum-injecting port jackscrews 5, big gland 6, firm banking 7, well head oil pipe 8, taper guide ring 9, tapered fibre ring 10, circular fiber wear ring and packing ring 11, last guide ring
Embodiment
Enumerate 1 embodiment below, the present invention is further specified, but the present invention is not only limited to this embodiment.
After Banbury mixer is warming up to 150 ℃, 4 kilograms of tetrafluoroethylene, 04,2 kilograms of Graphite Powder 99s of 3 kilograms of fluororubber 26s, 0.6 kilogram of aramid fiber, 0.2 kilogram of molybdenumdisulphide and No. 3 vulcanizing agents of 0.2 kilogram of sulphur are fed intake in Banbury mixer, middling speed stirs banburying 1 hour, extrude the excellent type lock packing of required specification through single-screw machine, as required, cut out unified length specification.
The using method of lock packing: carry out as follows: with reference to accompanying drawing 1, (1), after tight head and well head install, put into tapered fibre ring 9 successively, circular fiber wear ring and packing ring 10, last guide ring 11, divide the individual filler storehouse of filling, (2), gas-tight silo upper press cover 2 is screwed, (3), after the upper gland packing filling, want the sealing fully of abundant assurance device and oil-field oil pumper polished rod, colloid-injecting gun 3 must be screwed in the threaded hole on device top, spin-up gum-injecting port jackscrew 4, in rifle, insert lock packing glue rod, pressure with spiral injects lock packing in gas-tight silo, when injecting at need, stop to inject, close the gum-injecting port jackscrew, (4), start well on the beam, 1 reciprocal 8 shutdown of oil-field oil pumper polished rod, filling colloid in manual colloid-injecting gun 3 is restarted well on the beam again, when filling glue rod is to good seal in the to-and-fro movement of oil-field oil pumper polished rod, stop filling, (5), in the oil-field oil pumper work 24 hours, answer the close observation leak case, if slight leakage is arranged, inject seal gum more on a small quantity, after having sealed, can reach the service requirements of not revealing for a long time; After operation for some time, if slight leakage is arranged, spin-up gum-injecting port jackscrew 4 rotates manual colloid-injecting gun 3 and directly replenishes small amount of filler glue rod.
