Abstract
The utility model relates to a well head anti-leakage long effective sealing device for a pumping unit, which has leakage, eccentric friction and corrosion resistant performances. The technical proposal is that: the well head anti-leakage long effective sealing device for a pumping unit with a sealing sleeve is characterized in that: the utility model also comprises a stainless steel sleeve, outside which a casing is arranged. The sealing sleeve is positioned between the casing and the stainless steel sleeve, and a sucker rod blocking device is fixedly connected with the upper end of the stainless steel sleeve. For adopting the structure of the stainless steel sleeve, the utility model can effectively protect a sucker rod to prevent the eccentric friction, corrosion and the other circumstances produced during the long term using,. Moreover, the replacing times of the sucker rod and the sealing sleeve are reduced, the service lives of the sucker rod and the sealing sleeve are prolonged and the productivity is promoted by the utility model.
Description
Technical field:
The utility model relates to the leakage-preventing long-term seal device of a kind of oil pumper well head.
Background technology:
At present, because of pumping production tree well head with sucker rod round-the-clockly in the open air rub partially, reason such as corrosion, cause phenomenons such as well head run, drip, leak, the serious waste energy, influence is produced.
The utility model content:
Goal of the invention of the present utility model is to provide a kind of leakage-preventing, anti-eccentric wear, the leakage-preventing long-term seal device of etch-proof oil pumper well head.
Realize the technical scheme of goal of the invention:
The leakage-preventing long-term seal device of a kind of oil pumper well head, have sealing shroud, it is characterized in that: also have the stainless steel sleeve pipe, stainless steel sleeve pipe arranged outside has housing, be provided with sealing shroud between housing and the stainless steel sleeve pipe, the pumping rod fasterner fixing apparatus is fixedlyed connected with stainless steel sleeve pipe upper end.
The beneficial effects of the utility model:
The utility model adopts the stainless steel sleeve tubular structure, can effectively protect sucker rod, avoids the long-term phenomenons such as the eccentric wear that produces, corrosion of using, and has also reduced replacing sucker rod and sealing shroud number of times, has prolonged the application life of sucker rod and sealing shroud, has improved productivity ratio.
Economic benefit:
1) reduce friction because of well head, motor load descends, but individual well save power in every year more than 10,000 degree.
2) change sucker rod and phenomenons such as sealing shroud number of times and well head run, drip, leak because of reducing, but individual well incremental oil production in every year 3-5 ton.
3) reduce friction because of well head and reduce and change sucker rod and sealing shroud number of times, but more than 30,000 yuan of individual well economical with materials in every year cost.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in the figure, the leakage-preventing long-term seal device of oil pumper well head has stainless steel sleeve pipe 1, stainless steel sleeve pipe arranged outside has housing 10, be provided with sealing shroud 6 between housing 10 and the stainless steel sleeve pipe, sealing shroud can also be a helixseal cover 5, and the pumping rod fasterner fixing apparatus is fixedlyed connected with stainless steel sleeve pipe upper end.The pumping rod fasterner fixing apparatus is made of claw 7, gland 8, clamping device housing 4, and claw is positioned at top, and the claw outside is with gland 8, and housing 4 bottoms are connected with the end seat 9 of stainless steel sleeve pipe upper end.The position of corresponding well head is provided with aligning bulb 3 between housing and sealing shroud.Stainless steel sleeve pipe bottom is provided with shut-in well switch 2.
During work, sucker rod is passed the stainless steel sleeve pipe, stainless steel sleeve pipe diameter is between 30-40mm, length is between 4 meters to 10 meters, the top of sucker rod is fixing by claw 7 realizations and stainless steel sleeve pipe, and the aligning bulb is installed in the position of corresponding well head, improves well head centering rate, make sealing shroud not be subjected to eccentric wear, improve the application life of sealing shroud.The shut-in well switch prevents that mainly sucker rod from disconnecting when coming off, and oil, gas, water spray from well head.When beam hanger disconnects, shut-in well switch auto-closing.
