Description
Technical field
The utility model relates to a kind of dynamic equilibrium adjuster of beam-pumping unit, belongs to oil recovery machiner field.
Background technology
Use oil pumper from underground extraction oil, wherein conventional beam-pumping unit application is maximum, can account for the more than 90% of oil pumper total amount.The beam-pumping unit of the present use of China has had tens0000 more than, and extensively adopting beam-pumping unit is because it is simple in structure, advantage reliable and easy to maintenance.But there is the unbalanced disadvantage of dynamic force in beam-pumping unit, this is that experts are well-known in the cycle that oil pump pumps.The oil pumper that oil well depth is 1500 meters, it is only 2.8 tons in the weight of down-hole pump rod, when oil pump is descending, just pump can be slided to lower extreme point by pump rod weight, when oil pump is up, must give the enough external force that overcomes pump rod weight and frictional resistance, it is wire rope pulling force upwards on walking beam, pump could be mentioned to upper extreme point, in the upper and lower stroke of oil pump, dynamic active force is unbalanced, this influence of unbalance power feeds back to through gear reduction unit on the pump reaction motor of oil pumper, show that in an oscillation cycle of oil pump, motor speed is sometimes fast and sometimes slow, the electric current that the variation of electric machine rotation makes output motor frequently time little variation when large, the copper loss of motor own and iron loss must be increased, make idle work, electric energy is consumed in vain.Evidence; this loss has 10%-15% electric energy; to can reach 18%, on the crank of reductor, balancing weight to be housed in order reducing the loss, in the time there is current imbalance; change by the rotating torque of adjusting balancing weight; but adjusting must be to carry out under stopped status, the heavy danger of working, nor be once adjustable putting in place; even if adjusted in the time that down-hole geological condition changes, all may there is at any time new imbalance.
Summary of the invention
The purpose of this utility model is to provide a kind of dynamic equilibrium adjuster of beam-pumping unit, and it installs dynamic equilibrium adjuster additional in the situation that not changing Pumping Unit, have applicability widely, optional equipment input cost is little, improves income, easy to adjust, can carry out oil pumper is in service.
The technical solution of the utility model is achieved in that the dynamic equilibrium adjuster of beam-pumping unit, by spring pedestal, cylindrical compression spring, spring draw-bar seat, spring pull bar, adjust long screw-button, walking beam pull bar, walking beam draw-bar seat composition, it is characterized in that: cylindrical compression spring one end is fixedly connected with spring pedestal by spring fixed block, the other end of cylindrical compression spring is fixedly connected with spring draw-bar seat by spring fixed block, spring pull bar one end is fixedly connected with spring draw-bar seat by pivot pin, the spring pull bar other end has long screw thread, the long screw thread of spring pull bar is that dextrorotation is connected with the right-handed thread of adjusting long screw-button one end to screw thread, walking beam pull bar one end is connected with walking beam draw-bar seat by pivot pin, the walking beam pull bar other end has left-handed long screw thread to be connected with the left hand thread of adjusting the long screw-button other end, spring pedestal is vertically fixedly connected on oil-pump base by connecting pedestal, walking beam draw-bar seat is fixedly connected with the walking beam of oil pumper.
Good effect of the present utility model be its in the situation that not changing Pumping Unit, install dynamic equilibrium adjuster additional, have applicability widely, optional equipment input cost is little, improves income, easy to adjust, can carry out oil pumper is in service.
Accompanying drawing explanation
Fig. 1 is section of structure of the present utility model.
Overall structure figure when Fig. 2 is enforcement of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as Fig. 1, shown in 2, the dynamic equilibrium adjuster of beam-pumping unit, by spring pedestal 1, cylindrical compression spring 2, spring draw-bar seat 3, spring pull bar 4, adjust long screw-button 5, walking beam pull bar 6, walking beam draw-bar seat 7 forms, it is characterized in that: cylindrical compression spring 2 one end are fixedly connected with spring pedestal 1 by spring fixed block 8, the other end of cylindrical compression spring 2 is fixedly connected with spring draw-bar seat 3 by spring fixed block 8, spring pull bar 4 one end are fixedly connected with spring draw-bar seat 7 by pivot pin 9, spring pull bar 4 other ends have long screw thread, the long screw thread of spring pull bar 4 is that dextrorotation is connected with the right-handed thread of adjusting long screw-button 5 one end to screw thread, walking beam pull bar 6 one end are connected with walking beam draw-bar seat 7 by pivot pin 9, walking beam pull bar 6 other ends have left-handed long screw thread to be connected with the left hand thread of adjusting long screw-button 5 other ends, spring pedestal 1 is vertically fixedly connected on oil-pump base 10 by connecting pedestal 16, walking beam draw-bar seat 7 is fixedly connected with the walking beam 11 of oil pumper.
The dynamic equilibrium adjuster of beam-pumping unit, its Principles of Regulation are: in the time that the P of walking beam 11 end peak moves from the top down, through walking beam pull bar 6 and spring pull bar 4, cylindrical compression spring 2 is compressed because walking beam 11 declines simultaneously, cause compressed cylindrical compression spring 2 to increase elastic potential energy.In the time that the P of walking beam 11 end moves from bottom to top, when wire rope 12 pulls pump rod 13, compressed cylindrical compression spring 2 extends and discharges the elastic potential energy of saving bit by bit when pump rod 12 declines, and elastic potential energy passes to walking beam 11 through spring pull bar 4 and walking beam pull bar 6, and auxiliary walking beam 11 upwards promotes.As long as according to the variation of drive motors 14 electric currents, rotation adjustment adjusts long screw-button 5 to change the entire length of walking beam pull bar 6 and spring pull bar 4, can change the amount of force that spring discharges, save the link of adjusting balancing weight 15, realize the object of regulating rotary kinetic moment.
This device installs additional at five types or the six type oil pumpers of 1500 meters of well depths, and the concrete data of cylindrical compression spring are as follows:
Type: end face polishes cylinder-shaped compression spring.
Spring steel wire diameter: 18mm
Mean diameter of coil: 150mm
Pitch: 55.4mm
The number of turns: 12+2=14
Length: 700mm
Material: 65 manganese
Quenching hardness: HRC45
