Description
Technical field
The utility model is a petroleum system oil pumper producing well, gets the special tool of " O " type packing in the dress packing box.
Background technology
At present, the oil pumper producing well of each oil recovery factory of petroleum system, employed packing box is basic identical, all is that the oil pumping polish rod by 1 o'clock and 1.2 o'clock disposes corresponding packing box.This packing box assembly is made of three parts, the bottom be eccentric flange, centre be the rubber gate, above be the packing box cavity.This cavity is to be made of the secondary cylinder, top one-level cavity internal diameter is bigger than following one-level cavity internal diameter, and the existing cylindrical structure of following one-level cavity also has the awl barrel structure, and the upper level cavity can hold " O " type packing of 10 disconnections, below the one-level cavity can hold " O " type packing of 9 disconnections.
In the annular housing of packing box, take out the operation of the packing or the packing of packing into, there is not special tool, adopt simple straight screwdriver to replace usually.The disconnection of " O " type packing that disconnects seam is broken in manual operations into two with one's hands during the sabot root, is enclosed within on the oil pumping polish rod; Advance packing the annular housing of packing box suitable for reading then; Hold screwdriver handle with the right hand afterwards, plane on the packing is pushed down in the screwdriver tip, the pushing downwards of the glossy bar periphery of lottery of lotteries symmetry; Till " O " type packing was shifted onto the bottom, each layer packing all will be operated like this.
If just changed the packing box of oil pumping polish rod, than sabot root effort in old packing box greatly toward the interior sabot root of new packing box.Because the internal diameter of " O " type packing is certain, and its internal diameter is littler than new oil pumping polish rod diameter, so will little by little squeeze in it with screwdriver during the sabot root.And with screwdriver when pressing down, the thrust of artificial hand is limited, instantly to the end which floor the time, the motionless situation in screwdriver top can appear.At this moment will put on pressure cap and turn down, after the packing in front is depressed, continue another packing of dress in packing box again, push up downwards with screwdriver, put on pressure cap again and push up downwards, such process will be through filling packing box several times.In the upper level cavity of packing box, adorn 8 packings needs for a long time.
The sabot root is identical with the method for upper level sabot root in the next stage cavity of packing box, and still, loading the one-level ratio, to load onto the one-level effort also bigger, because the next stage cavity internal diameter of packing box is little, and the cavity lower end is taper.
It is so uneasy outwards to get " O " type packing in the packing box cavity yet.Because the annular housing of packing box is not only narrow but also dark, use straight screwdriver get top which floor also than being easier to, as long as the tip of screwdriver is inserted in the disconnection seam of packing, on screwdriver handle, firmly can prize which floor packing of the top next once prizing with hand.And the packing of getting below four layers with straight screwdriver is just so uneasy, get packing though all use straight screwdriver or hook all the time, also can which floor following packing be taken out, but screwdriver or hook are not easy to put to good use in not only narrow but also dark packing box cavity very much, have the sensation that does not make effectively, the most of the time of changing packing all has been used on the link of getting packing.
In addition, when using straight screwdriver to get packing, the surface of internal cavity of frequent scratch oil pumping polish rod of the corner angle of its tip and packing box, caused the reduction of packing sealing performance in packing box, again owing on the polished rod scoring trace is arranged, make it in aspiration procedure, increase the weight of wearing and tearing to the packing inner sealing surface, thus the application life of having reduced packing.
The Chinese patent notification number is CN2135643Y, and a kind of replacing rod-pumped well mouth polish rod packing special vice is provided, and all belongs to the special tool of changing the wellhead polish rod packing with the utility model.
The utility model content
The purpose of this utility model is: provide the special use of a kind of oil pumping polish rod packing to get the dress device, can not only adorn and get packing, and can reduce the difficulty of changing packing, alleviated operator's labour intensity, shorten the time used when changing packing, improve and change the packing operating efficiency, and reduce of the scratch of instrument corner angle oil pumping polish rod and packing box inner surface.
The technical solution adopted in the utility model is: the special use of oil pumping polish rod packing is got the dress device mainly by getting the dress end and setting upright end and form, getting dress end top is fixed together with a right semicircular pipe or a left semicircle shape pipe lower end of setting upright end, it is characterized in that: getting dress end cross section is semi-round ring shape, gets dress end length between the 100-300 millimeter.Get the tooth that there is protrusion on dress limit, bottom, tooth is connected with the vertical limit of arc of getting the dress end.Get the tooth that protrude on dress limit, bottom, can insert the disconnection seam of " O " type packing that disconnects; Get the dress end when rotation, an end of " O " type packing of disconnection just can upwards be creeped along the vertical limit of arc, " O " type packing can be taken out or pack into.
Setting upright end is made up of right semicircular pipe and left semicircle shape pipe, become an annular after right semicircular pipe and left semicircle shape pipe are involutory, opposite position at right semicircular pipe and left semicircle shape pipe, the right semicircular pipe has axial dovetail groove, left semicircle shape pipe has axial swallow-tail form projection, the swallow-tail form projection can be inserted dovetail groove, and right semicircular pipe and left semicircle shape pipe is fixing, and the handle of the band screw of the symmetry of being fixed with is arranged respectively on the outer wall of right semicircular pipe and left semicircle shape pipe.Relative when right semicircular pipe and left semicircle shape pipe, when the swallow-tail form projection was inserted dovetail groove, right semicircular pipe and left semicircle shape pipe were formed a circle, and the inwall of circle is close on the oil pumping polish rod, rotates when setting upright end, plays stable effect of getting the dress end.
In order to make the cylindrical of getting dress end can adapt to packing box upper and lower cavity internal diameter, be fixed with arc thickening band getting the dress bottom.The base of arc thickening band is with to get dress bottom shape identical, and the employing sunk screw is fixed.
The described dress end top of getting is fixed together with the right semicircular pipe of setting upright end, and its fixing means can be welding.
The described dress end top of getting is fixed together with the right semicircular pipe of setting upright end, and its fixing means can be to get dress to hold with the right semicircular pipe as a whole.
The beneficial effects of the utility model are: the special use of the utility model oil pumping polish rod packing is got the dress device and is got interior 7 packings of next stage of packing box approximately with 1.5-2 branch clock time, gets 8 packings of upper level approximately with 1.5-2 branch clock time.Use the utility model to get, the sabot root is laborsaving, when subtracting, the corner angle of instrument and oil pumping polish rod or packing box inner surface do not have scratch.Can not only adorn and get packing, and can reduce the difficulty of changing packing, alleviate operator's labour intensity, shorten the time used when changing packing, improve and change the packing operating efficiency.
