Description
Technical field
The utility model relates to petroleum industry oil recovery machiner equipment technical field, and particularly beam type is not shut down the beam pumping unit of adjusting balance.
Background technology
When oil recovery well site beam pumping unit is worked, owing to the stressed of up-down stroke sucker rod varies in size, in a reciprocal process, great changes have taken place for suspension point place load, if do not adopt effective ways to carry out balance, can reduce the efficient of oil pumper, reduce the application life of reduction box and motor.The oil pumper that is in non-equilibrium state for a long time can produce high vibration, and then influences the intensity of connecting bolt between each parts, even cuts off connecting bolt, the major accident that causes oil pumper to overturn.
In order to eliminate these shortcomings, it is heavy generally to be added with bascule on the walking beam afterbody of oil pumper or crank.When in down stroke, the potential energy that sucker rod falls to being discharged rises to eminence with bascule by lower.When in upstroke, bascule is fallen by eminence, and the potential energy that stores in down stroke is discharged, and helps motor to promote sucker rod and oil column.If it is suitable that the weight of balance weight is selected for use, can guarantee that motor equates in upper and lower stroke acting, reach balance this moment during the oil pumper initial operation.
Beam pumping unit generally all is equipped with bascule at the walking beam afterbody, and the balancing weight of some is equipped with in this bascule inside.By the quantity of increase and decrease balancing weight, increase or reduce the weight of oil pumper afterbody bascule, thereby change the moment of bascule, and then adjust the balance of oil pumper.
At the scene along with the oil pumping operation carrying out, the down-hole oil mass can change along with collecting time, cause the variation of suspended weights on the oil pumper polished rod eye, cause initially adjusting balance oil pumper since suspension point place load change and be converted into imbalance by equilibrium state.Therefore every running a period of time of oil pumper all need the arrangement personnel be adjusted balance to the well site according to the down-hole actual conditions.
At present, it is to rely on artificial experience to judge that oil pumper is adjusted equilibrium state, and balance adjustment relies on manpower and finishes.Therefore each adjustment all need arrange 2～3 people to operate to the scene, and during adjustment, oil pumper must be shut down, and wastes time and energy, and the accuracy of balance is not high.
The utility model content
The purpose of this utility model is: a kind of beam pumping unit of adjusting balance of not shutting down is provided, can judges automatically and the real-time balance of well pumping unit state of adjusting under the non-stop-machine operating mode of oil pumper.
The technical solution adopted in the utility model is: do not shut down the beam pumping unit of adjusting balance, mainly be made up of base, support, reductor, crank, connecting rod, walking beam, horse head and balance weight.Top at base is fixed with support, and the top of support is by the middle part of pivot pin support walking beam, and an end of walking beam is fixed with horse head; Top at base is fixed with motor and speed reducer, and the output shaft of reductor is connected with crank, and the other end of crank is connected with connecting rod, and the other end of connecting rod is connected by pivot pin with the other end of walking beam; Driven by motor reductor rotation, reductor drives crank, and drivening rod moves up and down, and drives walking beam and also makes horse head drive sucker rod to move up and down.It is characterized in that: the end at the walking beam other end is fixed with clamped beam, and clamped beam is parallel with walking beam, and dock with the walking beam end clamped beam end; The other end at clamped beam has axis hole, has rotating shaft, rotating shaft to pass the rotating beam middle part of cuboid in the axis hole.Rotating beam can be along shaft swing.Lower end at rotating beam is fixed with balance weight, in the upper end of rotating beam axis hole is arranged, and has pivot pin, pivot pin to pass the pin hole of leading screw end in the axis hole, and the upper end by the pivot pin rotating beam is connected with leading screw; The plane is fixed with bearing on clamped beam, and bearing is connected with governor motion by axle; Governor motion comprises motor, reducer and nut; The motor output shaft connection reducer, reductor is connected with nut by gear; Leading screw is connected with nut.The drive nut of adjusting device rotates, and leading screw is moved forward and backward, the upper end of leading screw energy push-and-pull rotating beam, and rotating beam drives balance weight swing certain position, adjusts the equilibrium state of beam pumping unit.
Rotating beam is the box beam of cuboid by the steel plate welding, and clamped beam is the box beam of cuboid by the steel plate welding.
The beneficial effects of the utility model: the utility model is not shut down the beam pumping unit of adjusting balance, can be implemented under the oil pumper duty, promptly not under the stopped status, adjusts the balance of oil pumper, in addition, and simple in structure, dependable performance, operation, easy to maintenance.
