Abstract
A blowout prevention box multiplier mainly solves the problem that the packing of the prior blowout prevention box has serious abrasion, and is characterized in that a sealed grease cylinder (2) is arranged at the upper part of a partition board (10) of an blowout prevention box upper cover (1); the grease cylinder (2) is filled with grease; a base plate (3), a lower pressure plate (4) and an upper pressure plate (5) are sequentially arranged on a boss (9) at the upper part in the grease cylinder (2); a gland bush (6) is arranged between corresponding flutes of the lower pressure plate (4) and the upper pressure plate (5); a grease nozzle (7) is connected with the upper part of the side wall of a grease cylinder (2) ; the upper end of the grease cylinder (2) is connected with a gland (8) through threads; and the middle of the base plate (3), the lower pressure plate (4), the upper pressure plate (5) and the gland (8) has a hole, through which a polished rod passes. The blowout prevention box multiplier has the characteristic of prolonging the service life of the packing.
Description
Technical field:
The utility model relates to oil recovery field, oil field rod-pumped well used blowout prevention box, especially blowout prevention box synergistic device.
Background technology:
Along with Oilfield developing, environmental protection is more and more important.In order to improve environment protecting, the blowout prevention box is installed all on the oil pumper well head.And at present existing because long-time running and environmental factor, polished rod when down stroke, the dry grinding packing, make the packing serious wear, the packing life-span shortens greatly, needs often to change packing, thereby increased workman's workload, influenced the normal operation of oil well, increased cost for oil production.
The utility model content:
In order to solve the problem of existing blowout prevention box packing serious wear, the utility model provides a kind of blowout prevention box synergistic device, and this blowout prevention box synergistic device has the advantages that to prolong the packing life-span.
The technical solution of the utility model is: this blowout prevention box synergistic device comprises the blowout prevention box cover, airtight Grease tube is arranged at blowout prevention box cover dividing plate top, butter is housed in the Grease tube, be equipped with base plate, lower platen and top board successively on the Grease tube internal upper part boss, be equipped with sealing mat between lower platen and top board corresponding groove, the Grease tube side wall upper part is connected with grease nipple, and the Grease tube upper end is by the gland that has been threaded, and base plate, lower platen, top board and gland have the polished rod via hole between two parties.
The butter and the machine oil of mixing are housed in the Grease tube in the such scheme; Be connected with handle on Grease tube and the gland.
The utlity model has following beneficial effect: this blowout prevention box synergistic device is owing to take such scheme, because of the Grease tube of butter is housed in the having of blowout prevention box cover upper end, when the oil pumper down stroke, the butter in the Grease tube is to polished rod and packing lubricate, thereby significantly reduced the wearing and tearing of packing, prolonged the application life of packing, the number of times that minimizing is changed packing,, improved the operating efficiency of producing well, increase the oil recovery benefit, and simple in structure.This blowout prevention box synergistic device has the advantages that to prolong the packing life-span thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-blowout prevention box cover among the figure, 2-Grease tube, 3-base plate, 4-lower platen, 5-top board, 6-sealing mat, 7-grease nipple, 8-gland, 9-boss, 10-dividing plate.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this blowout prevention box synergistic device comprises blowout prevention box cover 1, blowout prevention box cover 1 goes out an airtight Grease tube 2 by dividing plate 10 in blowout prevention box cover 1 upper isolation, and the butter and the machine oil of butter or mixing is housed in the Grease tube 2, and Grease tube 2 main effects are to adorn butter; Grease tube 2 internal upper parts have boss 9, butt plate 3, lower platen 4 and top board 5 that boss 9 is main, be equipped with base plate 3, lower platen 4 and top board 5 on the boss 9 successively, be equipped with sealing mat 6 between lower platen 4 and top board 5 corresponding groove, by lower platen 4 and top board 5 fixing seal pads 6, by sealing mat 6 sealing polished rod via holes, prevent the butter leakage pollution environment in the Grease tube 2 again; Grease tube 2 side wall upper part are connected with grease nipple 7, annotate butter by grease nipple 7 in Grease tube 2; Grease tube 2 upper ends are by the gland 8 that has been threaded, and base plate 3, lower platen 4, top board 5 and gland 8 have the polished rod via hole between two parties.Be connected with handle on Grease tube (2) and the gland (8), by handle conveniently assemble and disassemble blowout prevention box cover 1 and gland (8).
During actual the use, at first original blowout prevention box cover is unloaded, by polished rod via hole 3 this blowout prevention box synergistic device is enclosed within on the polished rod then, to be connected with the blowout prevention box cover 1 of Grease tube 2 one on the blowout prevention box by screw thread again, in Grease tube 2, annotate butter by grease nipple 7 again, only annotate butter in summer and get final product, annotate the miscella of butter and machine oil in winter by a certain percentage.Because of in the Grease tube 2 of blowout prevention box cover 1 upper end, butter being housed, when the oil pumper down stroke, butter in the Grease tube 2 is to polished rod and packing lubricate, thereby significantly reduced the wearing and tearing of packing, prolonged the application life of packing, the number of times that minimizing is changed packing, save packing, reduced cost for oil production, improved the operating efficiency of producing well, increase the oil recovery benefit, and simple in structure.This blowout prevention box synergistic device has the advantages that to prolong the packing life-span thus.
