Abstract
The utility model relates to a tool for oil extraction in an oil field, and especially relates to a direct viewing type polished rod eye. The technical scheme of the utility model is that the direct viewing type polished rod eye comprises a polished rod eye body; thrust bearings for mounting braids are disposed on the upper side and the lower side of the polished rod eye body respectively; the polished rod eye body is designed to be a hydraulic cylinder which comprises cylinder bodies, pistons, piston rods, and sealed rings; the pistons are connected with the piston rods; the sealed rings are disposed between the piston rods and the cylinder bodies; an oil adding hole is arranged on the top of the cylinder bodies; a pressure meter is connected on the lower portion of the cylinder bodies; and hydraulic oil is filled in the cylinder bodies. The beneficial effects of the utility model are that the polished rod eye is designed to be the hydraulic cylinder and the load acted on the polished rod eye is shown on the pressure meter at any time so as to determine the work state of an oil well at any time and adjust the external output fire, thereby preventing the boiler from dry burning and coking, and minimizing fire accidents; the understanding of the load is helpful for the analysis of pipe column production so as to save the time of stopping an oil well for testing; and the production efficiency is improved.
Description
Technical field:
The utility model relates to a kind of oil field instrument, particularly a kind of direct viewing type hydraulic pressure polished rod eye.
Background technology:
Polished rod eye is the horse head of beam pumping unit in the oil field and the linkage of polished rod, at present, existing polished rod eye effect of using is single on the oil field pumping well, when needs carry out load measure to oil pumper, must when oil well pipe is analyzed, need stop well by the external testing instrument, cause production efficiency low, reduce crude output.
Summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of direct viewing type hydraulic pressure polished rod eye is provided, and can get information about Oil Well Working at any time.
Its technical scheme is: be made up of the polished rod eye main body, the both sides up and down of polished rod eye main body are respectively equipped with the thrust bearing that the hair plait is installed, described polished rod eye main body adopts hydraulic cylinder, described hydraulic cylinder is made up of cylinder barrel, piston and piston rod, sealing ring, the top of piston connects piston rod, is provided with sealing ring between piston rod and the cylinder body, and a side on cylinder body top is provided with tank filler sleeve, inferior part of the cylinder block connects pressure meter, and hydraulic oil is housed in the cylinder body.
The beneficial effects of the utility model are: with the polished rod eye body design is hydraulic cylinder, can demonstrate the load that acts on the polished rod eye at any time by pressure meter, judge Oil Well Working at any time, adjust outer defeated stove fire, avoid burner hearth dry combustion method coking, less accident fire; Can produce the analysis of keeping a grip on by understanding, save the time of menelipsis test load; Improved production efficiency.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: polished rod eye main body 1, piston 2, cylinder body 3, thrust bearing 4, tank filler sleeve 5, sealing ring 6, pressure meter 7, piston rod 8.
The specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model comprises polished rod eye main body 1, the both sides up and down of polished rod eye main body 1 are respectively equipped with the thrust bearing 4 that the hair plait is installed, design hydraulic cylinder on the described polished rod eye main body 1, described hydraulic cylinder is made up of cylinder body 3, piston 2 and piston rod 8, sealing ring 6, the top of piston 2 connects piston rod 8, is provided with sealing ring 6 between piston rod 8 and the cylinder body 3, and cylinder body 3 tops are provided with tank filler sleeve 5, cylinder body 3 bottoms connect pressure meter 7, and hydraulic oil is housed in the cylinder body.
During use, polished rod is inserted polished rod eye endoporus 9, the top is fixed by clamp, according to liquid pressurized in confined space, outwards transmitting the identical principle of pressure, is hydraulic cylinder with the body design of common polished rod eye, when upper pressure presses down, hydraulic oil in the squeeze cylinder, show the load that acts on the polished rod eye by the pressure meter 7 that is connected with cylinder body, judge Oil Well Working at any time, adjust outer defeated stove fire, avoid burner hearth dry combustion method coking, less accident fire; Can produce the analysis of keeping a grip on by understanding, save the time of menelipsis test, improve production efficiency load.
