Abstract
The utility model relates to a sealing packing for an oil pump. The utility model has the improvement that a packing is changed into a spiral-shaped packing. The improvement of the utility model solves the puzzle which always obsesses people, on the one hand, the operation of assembling incision can be thoroughly relieved, the sealing performance can be improved, and on the other hand, the replacing operation of the installation and the extraction of the utility model is convenient. When the utility model is assembled, the packing only needs to be screwed and tightly pressed. When the utility model is taken out, the upper end of the packing needs only to be dragged, so that the whole packing can be easily pulled out or wound out. The utility model has the advantages of simple structure, science and reasonableness. The utility model can obtain great popularization and application on oil fields.
Description
The utility model relates to a kind of used for oil extractor sealed packing, belongs to Sealing.
The sealing of pumping unit beam hanger realizes that by packing, packing box and packing lid packing is a Sealing, and original packing during use uses a plurality of annular seal packing stacks all in the form of a ring.Owing to structural reason, when mounted, the annular seal packing must be cut an angle, one by one a plurality of sealed packings are set on the beam hanger.Be subjected to the influence of otch, the sealability of packing is not good enough.Along with continuous advancement in technology, the packing development that also more and more improves, my application number declared in January, 1999 is 99219635.3, and the improvement technology that name is called pumping unit beam hanger seal ring surely belongs to a kind of preferably, makes packing in use can keep excellent sealing performance.But, still have another difficult problem pendulum at present in face of us, packing is difficult to take out from packing box, especially the packing of packing box bottom.Packing belongs to easily damaged parts, and life cycle was generally about one month, and only use on some pumping unit just needed to change once in 5-7 days.The annular seal packing is contained in the packing box of tubular, in the middle of the packing box beam hanger is arranged again, and the space between packing box and beam hanger is very little, and therefore, it is very difficult that operation is changed in the taking-up of annular seal packing.
The purpose of this utility model is to provide a kind of not only good seal performance, and takes out and change used for oil extractor sealed packing easy to operate.
Used for oil extractor sealed packing described in the utility model, its improvement is to change packing into helical.
Used for oil extractor sealed packing described in the utility model is the unitary whole structure.
Improvement of the present utility model on the one hand, has thoroughly been exempted the problem of otch, and its sealability is greatly improved; On the other hand, its installation and taking-up are changed easy to operate, and during installation, only need screw on packing to compress and get final product, during taking-up, as long as catch hold of the upper end of packing, just at an easy rate whole packing is pulled out or laid out.
As can be seen, the utility model is simple in structure, and is scientific and reasonable, solved a difficult problem that is always troubling people, and not only good seal performance, and installation, taking-up are changed easy to operate, can be applicable widely on the oil field.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1, a structural representation of the present utility model also are an embodiment.
As shown in the figure, used for oil extractor sealed packing described in the utility model is holistic helical.
Claims (2)
1, a kind of used for oil extractor sealed packing is characterized in that packing shape in the shape of a spiral.
2, packing according to claim 1 is characterized in that packing is the unitary whole structure.
