Therefore, the balance effect of the pumping unit can be improved, the net torque peak value of a crank output shaft is reduced, the stress of the four-bar mechanism is reduced, the swing angle of the walking beam is increased, a long stroke is obtained, the energy consumption is reduced, and the efficiency is improved.
Description
The present invention relates to a kind of oil rig of recover petroleum, 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 object of the present invention is to provide a kind of curved beam pumping unit, 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 realizes by following scheme: a kind of curved beam pumping unit, 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 walking-beam counterweight is installed.
The installation quantity and the adjustable positions of walking-beam counterweight.
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 invention 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 embodiments of the invention are 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.
Among the figure: 1 base, 2 supports, 3 walking beam bearings, 4 hangers, 5 horse heads, 6 walking beams, 7 crossbeams, 8 walking-beam counterweights, 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 walking-beam counterweight 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.
In the pumping unit working procedure, the acting force arm of walking-beam counterweight 8 is among the variation all the time, and the trend of variation is, when upstroke begins with the down stroke end, because of polished rod load is bigger, the acting force arm of walking-beam counterweight 8 is longer, so that loading is unlikely to excessive to the load-torque of crankshaft; When upstroke end and down stroke began, less because of polished rod load, at this moment the acting force arm of walking-beam counterweight 8 was shorter, so that loading is unlikely to too small to the load-torque on the crankshaft.Thereby load-torque is close with sinusoidal rule as far as possible with the rule that the crank angle changes, reaches the counterbalance effect of strengthening pumping unit, reduce the peak value of crankshaft output net torque, reduce the valley degree of depth (absolute value), reach the purpose that cuts down the consumption of energy.
Equally, the adjustment of walking-beam counterweight 8 positions is according to the needs of operating mode next certain (because originally a bite oil well from recovering the oil finally, its operating mode is changing, and polished rod load is also changing thus) always, when little load, the quantity of walking-beam counterweight 8 will be lacked, and the position will be near the hinged point of walking beam 6, and promptly equilibrant does not need too big, when load becomes big, the equilibrant that needs is big, and at this moment the quantity of walking-beam counterweight 8 will increase, and the position is moved after wanting.
As the variation of Fig. 2, walking beam shown in Figure 36 structural types such as arc, " Z " shape etc. is according to making and the on-the-spot needs that recover the oil design, purpose is under the prerequisite that satisfies this type characteristics, make as far as possible that manufacturing process is simple, field operation is convenient, do not need to add complicated frock and equipment etc.
The variation of the mounting point of walking beam bearing 3 (top, middle part, bottom) is in order to realize following purpose.Hinged bottom at walking beam 6 belongs to conventionally form, and the top that hinged point is positioned at walking beam 6 is to be in object of energy saving equally.When upstroke end down stroke began, the center of gravity arm of force of leading portion walking beam was longer; And when down stroke end long stroke began, the leading portion walking beam center of gravity arm of force was shorter.
Hinged point is positioned at the middle part of walking beam 6, can realize a kind of change walking beam form, and promptly horse head 5 is circular, realizes big corner, increases stroke.
