Description
Affiliated technical field
The present invention relates to a kind of oil pumper of crude oil exploitation, especially can be as the cluster well crude oil production.
Technical background
Present known no beam pumping unit can only be pumped as individual well, and can not be as to cluster well, promptly before and after oil pumping two mouthfuls of wells the time.
Summary of the invention
In order to overcome the deficiency of existing no beam pumping unit, the invention provides a kind of oil pumper, this oil pumper not only can be pumped as individual well, and can be as the oil pumping of oil well before and after the cluster well.
The technical solution adopted for the present invention to solve the technical problems is: on the upper mounting plate of tower-type headframe, external rotor permanent magnet synchronous machine is installed, two guide wheels are installed about the downside of motor cabinet, at the top of derrick left and right sides two guide wheels are installed again, with flexible strap external rotor electric machine and 4 guide wheels are connected in regular turn, the movable pulley of respectively connecting in the both sides, front and back again, below two movable pulley, connect polished rod eye with suspension hook, centre bore at polished rod eye is located in polished rod on the polished rod eye with square clamp, just constitutes people's bodily form oil recovery trailer system thus.The Based Intelligent Control cabinet is installed in the derrick side again, is connected with external rotor permanent magnet synchronous machine, constitute the dynamical system of oil pumper with lead.Above-mentioned external rotor permanent magnet synchronous machine is to be made of outer rotor, inner stator, motor shaft, support.Its outer rotor is the outer rotor of motor, is again the driving wheel of trailer system, the brake wheel of security system.Above-mentioned movable pulley, its pulley spoke outer rim is a multi-groove structure, so that many wire rope pass simultaneously, before and after the trailer system movable pulley of respectively connecting, make the load that acts on the motor outer rotor reduce half, thereby the diameter of motor is reduced, make the bearing load of wire rope reduce half simultaneously, so that prolong its application life.Above-mentioned flexible strap can be wire rope, chain, belt, and wire rope can be many, so that prolong the life-span of wire rope.Above-mentioned polished rod eye is provided with a spring in its housing, during as if oil well pump generation holddown, because the cushioning effect of spring, so that wire rope is shielded.Described spring can be that helical spring also can be the butterfly spring.This its operating principle of type oil pumper is as follows: after external rotor permanent magnet synchronous machine energising running, suppose to clockwise rotate, at this moment, wire rope on the motor outer rotor steel wire rope groove relies on its frictional force just to rotate with motor synchronous, so wire rope drives the suspending point loading of front side and moves to top dead centre, thereby drive sucker rod, oil well pump oil pumping.Meanwhile, the wire rope of motor rear side drives suspending point loading and moves to lower dead center, and drive sucker rod, oil well pump move to lower dead center, thereby finish oil-absorbing process.In this process, the driving force that the active force on the wire rope not only has motor to provide is provided, and also has the gravity of the movable pulley, bar, fluid column, pump etc. of front side, the gravity of the movable pulley wheel of rear side, bar, fluid column, pump etc.Because the front and back load is almost equal, therefore under the situation of no external force effect, they are in equilibrium state, if want their motions, then will provide certain driving force by motor.During operation, when the front side suspending point loading arrives top dead centre, when the rear side suspending point loading arrived lower dead center, the position sensor of control system just obtained signal, feeds back to control system immediately, stop power supply to motor, provide reversing the current to motor again after a while, then motor just be rotated counterclockwise, at this moment, front side movable pulley, bar, fluid column, pump move to lower dead center, the beginning oil-absorbing process.The movable pulley of rear side, bar, fluid column, pump move to top dead centre, the beginning oil pumping process.Suspending point loading when the front side arrives lower dead center, when the suspending point loading of rear side arrives top dead centre, the position sensor of the control system signal of just getting back, feed back to control system immediately, stop power supply, provide forward current to motor again after a while, just change so motor begins a new round again to motor, so go round and begin again, the front and back oil well just constantly is drawn into ground with underground crude oil.
The invention has the beneficial effects as follows: can utilize a motor is that two mouthfuls of oil wells draw, and saves electric power at double, significantly improves efficient, saves the oil pumper manufacturing cost at double.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples
Fig. 1 is a lateral view of the present invention
Fig. 2 is a front view of the present invention
Fig. 3 is the polished rod eye sectional view
Among the figure: 1, external rotor permanent magnet synchronous machine, 2, guide wheel I, 3, guide wheel II, 4, wire rope, 5, movable pulley, 6, polished rod eye, 7, frame, 8, sling, 9, the Based Intelligent Control cabinet, 10, the polished rod eye housing, 11, spring.
The specific embodiment
In Fig. 1 embodiment, motor 1 is installed on the upper mounting plate of frame 7, installation guide wheel 2 below upper mounting plate, side is installed guide wheel 3 before and after the top of frame 7, the front end of wire rope 4 is walked around from the steel wire rope groove of motor 1, through guide wheel 2, guide wheel 3, walk around in the follow-up pulley 5 again, fag end and upper end sling 8 places are fastened.Again with the rear end of wire rope 4 from guide wheel 2, guide wheel 3, movable pulley are walked around successively, at last the sling 8 on fag end and top are fastened.In order to prolong the application life of wire rope, coarse-wire rope can be resolved into many seizing wires, make the flexible increase of wire rope, radius of curvature increases when crooked.
In Fig. 2 embodiment, with lead Based Intelligent Control cabinet 9 and external rotor electric machine 1 are coupled together, lower dead center sets position sensor on polished rod eye 6 again, connect the power supply rear motor and just can rotate (being assumed to be clockwise), when lower dead center was gone up in arrival, position sensor just indicated Based Intelligent Control cabinet 9 to change the senses of current, thereby made motor 11 counter-rotatings, so go round and begin again, just underground crude oil can be drawn into ground.
In Fig. 3 embodiment: in the endoporus mounting spring 11 of polished rod eye body 10, when the weight loading of bar, fluid column, pump all is located on the polished rod eye, rely on the cushioning effect of spring, can improve the running quality of machine, bar, pump, if during oil well pump generation holddown, unexpected additional load that can buffer rope prolongs its application life.
