Abstract
The utility model relates to a lubricating sealing device, which is composed of a gland bush 1, an oil seal 2, an oil seal box 3, a spongy mass 4, a cap 5, and a filler 6. The lubricating sealing device adopts the gland bush which is in screw connection with the cap, the inner part of the gland bush is provided with the oil seal, the oil seal box, and the spongy mass respectively from top to the bottom, the outer part of the cap is provided with the filler, a pumping rod slides from the top to the bottom in the filler, and the pumping rod body is lubricated so as to reduce the friction with the oil seal. The utility model has the advantages of pressure-proof and good sealing effect, which can reduce the time for changing the packing and the frequency of oil leakage, and can increase the output and save the cost price. The utility model also has the advantages of simple structure, professional design, and popularization and application on the job site.
Description
Technical field
The utility model relates to the downhole tool that uses on a kind of oilfield, particularly a kind of lubricated type sealer.
Background technology
The sealed packing of the aboveground use of usually oil, when in a single day oil well not fuel-displaced, sucker rod and packing dry grinding, cause the packing wearing and tearing, will not cause, because of poorly sealed phenomenon of running oil if at this moment in time be found, change packing when giving this mouthful well, lost the opportune moment of volume increase, brought unnecessary loss, also wasted great amount of manpower and material resources simultaneously to enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of lubricated type sealer.It is withstand voltage, good sealing effect, has reduced the time of changing packing and has run the crude oil number of times, improves output, is saving cost.
The purpose of this utility model is to realize like this, it is made up of gland (1), oil sealing (2), oil sealing box (3), cavernous body (4), pressure cap (5), oil filler (6), gland (1) is threaded with pressure cap (5), in gland (1), be followed successively by oil sealing (2), oil sealing box (3), cavernous body (4) from top to bottom, cavernous body (4) drops on the interior baffle ring of pressure cap (5), oil filler (6) is arranged outside pressure cap (5), and sucker rod (7) therefrom passes.
During work, from the oil filler apply oil, cavernous body absorbs, and sucker rod slides up and down therein, the lubricated oil pumping body of rod, thus the friction of reduction and oil sealing makes oil sealing sealing good, improves application life.
The utility model is owing to adopted gland to be threaded with pressure cap, in gland, be followed successively by oil sealing, oil sealing box, cavernous body from top to bottom, oil filler is arranged outside pressure cap, sucker rod slides up and down therein, the lubricated oil pumping body of rod, thereby the friction of reduction and oil sealing, it is withstand voltage, good sealing effect, reduce the time of changing packing and run the crude oil number of times, improved output, saved cost.The utility model is simple in structure, and is reasonable in design, is well suited for field popularization application.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
The specific embodiment
As shown in the figure, the utility model is made up of gland 1, oil sealing 2, oil sealing box 3, cavernous body 4, pressure cap 5, oil filler 6, gland 1 is threaded with pressure cap 5, in gland 1, be followed successively by oil sealing 2, oil sealing box 3, cavernous body 4 from top to bottom, cavernous body 4 drops on the baffle ring in the pressure cap 5, oil filler 6 is arranged outside pressure cap 5, and sucker rod 7 passes therein.
