Technical field
The invention belongs to the oil pumper field in the oil recovery machiner, is a kind of direct driving type multi-stroke multi-well oil pumping machine specifically.
Background technology
At present a lot of oil wells are beaten in the place that focuses mostly on, each oil field, and every mouthful of oil well all has a pumping production, has increased investment and energy consumption, also makes the structure of equipment more complicated.
Summary of the invention
The objective of the invention is to overcome the difficult problem of existing oil pumper technology, be used to satisfy the demand of oil pump energy-saving, use direct driving type multi-stroke multi-well oil pumping machine and recover the oil, realization can alleviate the purpose that existing oil pumper weight also can reduce oil pumper work power consumption simultaneously.
The objective of the invention is to realize by following technical solution:
Above-mentioned direct driving type multi-stroke multi-well oil pumping machine is characterised in that each oil well all has different supports, outputting power be main support, the support of all the other each oil wells is a sub-stent, provide power at oil pumper main support top by low speed large torque rotating frequency modulation motor, the positive and negative rotation of frequency modulator and cyclelog control frequency modulation motor, directly drive active force roller and main suspending weight roller rotating swing by coaxial speed reducer, the rotating swing of the suspending weight roller on the main support lifts the sucker rod oil pumping of following oil well, the different races of the power roller of the different race respective branches framves of the power roller of main support, the transmission of power on the power roller on the main support on the power roller on the sub-stent, power roller on the sub-stent is given the suspending weight roller transmission of power, the swing that drives the suspending weight roller on the sub-stent lifts the sucker rod oil pumping of following oil well, and the different-diameter of suspending weight roller has different strokes when making each oil well oil-pumping.
The different slots position of the power roller on the main support on the above-mentioned middle oil well connects the power roller on the sub-stent of other each oil well, to other sub-stent transmitting power, the other end of the power roller of each sub-stent upper end is that the suspending weight roller comes corresponding following well recovery, the suspending weight of each oil well is balance each other, and there is the difference after one or two balancing weight comes each oil well balance of balance the lower end of the power roller on the main support.
Characteristics of the present invention are:
1, driving many mouthfuls of oil wells by a power pumps simultaneously, make the structure of oil pumper simpler, oil pumping management is convenient, and the idle work of the down stroke of a bite oil well is converted into the useful work of another mouthful oil well, and the direct driving type multi-stroke multi-well oil pumping machine economize on electricity can reach 50%.
2, with the suspending weight of each oil well balance each other, the counterweight of having saved oil pumper.
3, can realize the different strokes of every mouthful of oil well, the different-diameter of suspending weight roller has different strokes when making each oil well oil-pumping.
4, the suspending weight roller on the main support of direct driving type multi-stroke multi-well oil pumping machine can disconnect, and transmission is independent of each other, and can drive the oil well of different numbers, also can be used as the individual well oil pumper and uses.

The specific embodiment
Now the present invention is further described as follows with the specific embodiment in conjunction with the accompanying drawings:
From Fig. 1～Fig. 3 as seen, the present invention includes main support 1 and the power set that are installed in its top, these power set comprise variable-frequency motor 5, suspending weight roller 9 and polished rod eye 4, and the output shaft of variable-frequency motor 5 is in transmission connection by speed changer 6 and suspending weight roller 9, is connected with polished rod eye 4 on this suspending weight roller 9.Around described main support 1, be provided with sub-stent 2, power roller 10 and coaxial suspending weight roller 11 are housed on each this sub-stent 2, on each suspending weight roller 11, all connect a polished rod eye 4; Connect a power roller 7 coaxial at the output of described speed changer 6 with described suspending weight roller 9; Different groove positions is being arranged on the power roller 7 on the described main support 1 and linking to each other by the groove position on the power roller 10 on soft rope 3 and each sub-stent 2, power roller 7 on this main support drives the power roller 10 of each sub-stent, realizes many mouthfuls of oil wells of a power drive.
Described suspending weight roller 9 can have different diameters with 11, and different strokes are arranged during with the realization oil pumping.
The lower end of the power roller 7 on described main support 1 is provided with one or two balancing weight 8, be used for the quantity (side as main support 1 is a sub-stent 2, and opposite side is two sub-stents 2) of each sub-stent 2 (oil well) of balance or the difference of the driving driving force that force unbalance caused.
Suspending weight roller 11 on the described sub-stent 2 can separate with power roller 10 and disassembles, and stops the work of this mouthful oil well separately, and whole multiple well pumping unit can become twin-well oil-pumping machine or individual well oil pumper.
The course of work of the present invention is, main support 1 on the main oil well is given sub-stent 2 transmission of power by soft rope 3, corresponding every mouthful of oil well below the polished rod eye 4 on each oil well, power transmission is such, at first swing by power roller 7 and the suspending weight roller on the body frame 9 that reducer 6 drives on the main support 1 at the low speed large torque rotating frequency modulation motor on the main support 15, the swing of the suspending weight roller 9 on the main support lifts the sucker rod oil production of following oil well by polished rod eye 4, power roller 7 on the body frame 1 provides power to power roller 10 on the sub-stent 2 and the suspending weight roller 11 on the sub-stent 2 by soft rope 3 simultaneously, and the swing of the suspending weight roller 11 on the sub-stent 2 lifts the sucker rod oil production of following oil well by polished rod eye 4.The suspending weight of each oil well is balance each other, weight difference after each oil well suspending weight balance of balancing weight 8 balances, suspending weight roller 11 on each sub-stent 2 can be extractd power from power roller 10 simultaneously, stop the work of this mouthful oil well separately, whole multiple well pumping unit can become twin-well oil-pumping machine or individual well oil pumper, all the other each oil wells can continue operate as normal, and simultaneously the suspending weight roller 9 of different-diameter has different strokes when 11 can make following oil well oil-pumping.
