Abstract
The utility model relates to an oil pumping device for oil production, which belongs to a bent walking beam oil pumping machine. The bent composite balancing walking beam oil pumping machine is formed by that the tail end of a walking beam is provided with a bent walking beam used for the installation of a quantitative balancing weight, and a walking beam supporting seat is installed on the middle part, the upper part, or the lower part of the walking beam. As a result, the balancing effect of the oil pumping machine can be improved, the net torque peak value of an output shaft of a crank can be decreased, the stress of a four-rod mechanism can be reduced, the swinging angle of the walking beam can be increased, the long stroke can be obtained, the energy consumption can be lowered, and the efficiency can be improved.
Description
The utility model relates to liter a kind of oil rig of quarrying oil, and it belongs to a kind of curved beam pumping unit.
At present, for oil well that can not blowing, generally adopt the mechanical type pumping unit to recover the oil, as most widely used beam pumping unit, its walking beam is hinged on support by the walking beam bearing, horse head is installed in the walking beam front end and is connected with sucker rod by the suspension rope hanger, the walking beam rear end is hinged by crossbeam and connecting rod, motor drives connecting rod work through retarder, connecting rod is by crossbeam transmission walking beam reciprocally swinging in vertical guide, thereby drive the upper and lower to-and-fro motion of sucker rod by horse head, suspension rope hanger, realize oil pumping.Beam pumping unit has reliable operation, fastening durable, easy to maintenance, can be operated in the field throughout the year and not need advantages such as the special messenger guards, therefore, for over 100 years more than a hundred years, it is the first that beam pumping unit consumption in mechanical oil recovery occupy always, but its deficiency is: common beam pumping unit is subjected to the influence of its " four bars " mechanism, the load-torque that causes the pumping unit polished rod load to affact on the crank changes not according to sinusoidal rule, add the influence of the additional loads such as suspension point inertial load in the work, make the load-torque curve distortion occur, the crank balance moment of torsion that changes by sinusoidal rule can not be well balance with it, bigger peak value and less paddy (bearing) value appear in the clean moment of torsion that crank-motion was exported in one week, thereby increased the energy consumption of pumping unit, reduced the efficient of pumping unit, negative torque also can influence the working life of retarder etc. simultaneously.
Along with Oilfield developing, oil well liquid level descends, and whale day by day reduces, and the input amount of pumping unit constantly increases, and makes long dashing take out deeply and improve efficiency of the pumping unit, and problem such as cut down the consumption of energy more and more looms large.
The purpose of this utility model is to provide a kind of curved beam pumping unit, and it can avoid deficiency of the prior art, and the stroke of its pumping unit is long, energy consumption is low, efficient is high, sturdy and durable, easy to operate.
Above-mentioned purpose is a kind of curved beam pumping unit of realizing by following scheme, its support, retarder all are fixed on the base, the rack-mount end of walking beam bearing, link assembly one end is connected with crossbeam on being fixed on walking beam, the other end is connected with the crank of connection reducer and crank balance, its technological scheme is that crooked shape is made in the walking beam rear end, and at the rear end end terminal equilibrium block is installed.
The quantity of the equilibrium block of walking beam rear end and adjustable positions.
The walking beam bearing can be installed on the fulcrum at walking beam top, bottom or middle part; Walking beam can be made into " bow " word or " Z " font.
Characteristics of the present utility model are:
1, improves the counterbalance effect of pumping unit, reduced the peak value and the valley of oil pumping machine crank axle output net torque.
2, reduce the stressed of fourbar linkage, relatively increased angle of oscillation, obtained long stroke; Improve the reliability of member, had simple in structure firm, the durable characteristics of conventional pumping unit.
3, the energy consumption of pumping unit is reduced, improve overall efficiency.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:
Accompanying drawing 1 curved beam pumping unit structural representation.
Accompanying drawing 2 curved beam pumping unit walking beams and walking beam bearing schematic representation.
Accompanying drawing 3 curved beam pumping unit walking beams and walking beam bearing schematic representation
1 base among the figure, 2 supports, 3 walking beam bearings, 4 hangers, 5 horse heads, 6 walking beams, 7 crossbeams, 8 beam balances, 9 link assemblies, 10 crank balances, 11 cranks, 12 retarders.
As shown in the figure, support 2 and retarder 12 all are fixed on the base 1, and walking beam bearing 3 is installed in the top of support 2, and the walking beam 6 of making crooked shape is the top that radially is connected and is fixed in walking beam bearing 3 by best fulcrum with walking beam bearing 3.Front end at walking beam 6 is installed horse head 5 and hanger 4, and a beam balance 8 is installed in the rear end of walking beam 6; At walking beam 6 curved parts, link assembly 9 one ends are connected with crossbeam 7 crossbeam 7 by Bearing Installation, and the other end is fixed on the crank 11 of connecting crank balance 10 and retarder 12.After retarder 12 drove connecting rod work, crank 11 and link assembly 9 drove walking beam 6 reciprocally swinging in vertical guide through crossbeam 7,4 upper and lower motion realization oil pumping under the effect of horse head 5 of its hanger.
