The screw-type oil pumping machine has the advantages of simple mechanical structure, reliable operation, small size, less investment, convenient maintenance, long service life, stable starting of the motor, wide variable-frequency speed regulation range, stable rotation speed and torque, stable operation, high power, high power factor, high efficiency and low energy consumption.
Description
Technical field
The utility model relates to a kind of screw oil pumper, is suitable for oil field oil pumping operation.
Background technology
The oil pumper in existing oil field is when the oil pumping operation, adopt the huge oil field pump oil pumper structure of kowtowing, complex structure, huge, investment is big, safeguard inconvenient, need than big staring torque in start-up course, oil pumper adopts threephase asynchronous as power source, when normal oil pumping moves, the load factor of motor is about 30%～50%, makes the oil-field oil pumper motor have shortcomings such as serious " low load with strong power " problem and efficient and power factor are low.Therefore, how addressing the above problem is research object of the present utility model.
Summary of the invention
The utility model relate to a kind of simple in structure, reliable, volume is little, the screw oil pumper of easy to maintenance, long service life.
Its solution is: a kind of screw oil pumper, comprise oil pick-up tube, and it is characterized in that: the perpendicular lifting screw transmission mechanism that drives the oil pumping plunger that is equipped with of described oil pick-up tube tube cavity, described oil pick-up tube pipe side is provided with oil-out.
Advantage of the present utility model is: the utility model frame for movement is simple, reliable, volume is little, reduced investment, easy to maintenance, long service life, and motor start-up steadily, frequency control wide ranges, rotating speed and torque is steady, stable, efficient is high and power factor is high, energy-efficient.

The specific embodiment
With reference to figure 1 and Fig. 2, a kind of screw oil pumper comprises oil pick-up tube 1, it is characterized in that: the perpendicular lifting screw transmission mechanism 2 that drives the oil pumping plunger that is equipped with of described oil pick-up tube 1 tube cavity, described oil pick-up tube 1 pipe side is provided with oil-out 3.
Above-mentioned elevating drive mechanism 2 comprises respectively and just being in transmission connection with screw rod 2-1 top, reverse drive nut sleeve 2-2,2-3, described nut sleeve outer rim is provided with driven driving cog, the driven driving cog 2-4 of described forward transmission nut cover 2-2 is by initiatively travelling gear 2-5 driving of forward, the driven driving cog 2-6 of described reverse drive nut sleeve 2-3 is driven by reverse active travelling gear 2-8 through intermediate drive gear 2-7, just described, reverse initiatively travelling gear 2-5,2-8 is coaxial respectively to be installed on the driving shaft 2-9, just, reverse initiatively travelling gear 2-5, the tooth of 2-8 is arranged between 0 °～180 ° of circumference of gear and interlaced installation.
Above-mentioned oil pick-up tube 1 body upper outside is provided with the gear graduation motor drive mechanism 2-10 that drives driving shaft 2-9 motion.
Above-mentioned screw rod 2-1 upper end hangs 6 the end of heavily restricting and connects, and described suspension 6 other ends of heavily restricting are walked around the pulley 4 be located on the body upper inside wall and weight 5 is connected.
Said gear variable-speed motor structure 2-10 adopts three-phase high-efficient energy-saving rare earth permanent magnet frequency control synchronous motor.
The specific implementation process is: rotate through gear graduation motor drive mechanism 2-10 variable speed drives driving shaft 2-9, driven wheel 2-5 and gear 2-8 running, when gear 2-5 works, gear 2-5 transmission has the forward transmission nut cover 2-2 rotation of driven driving cog 2-4, forward transmission nut cover 2-2 rotation drive screw 2-1 rotation is up, and the screw oil pumper carried out oil pumping work when screw rod 2-1 was up; When gear 2-8 running work, gear 2-8 running transmission intermediate drive gear 2-7, intermediate drive gear 2-7 transmission has the reverse drive nut sleeve 2-3 rotation of driven driving cog 2-6, reverse drive nut sleeve 2-3 rotation drive screw 2-1 rotation is descending, and the screw oil pumper carried out oil suction work when screw rod 2-1 was descending.The screw rod uplink and downlink are back and forth realized oil well pump work.
On the screw rod, descending active travelling gear 2-5,2-8 is the wheel hub of the different numbers of teeth of part, on, descending active travelling gear 2-5, the teeth 2-4 of 2-8,2-6 is staggered to be installed on the coaxial 2-9, as shown in Figure 2, on, descending active travelling gear 25, the mutual combined crosswise work of 2-8, at gear 2-5, be provided with during 2-8 exchange work, following buffer area in the ranks, buffer area plays the mechanical damping effect, and make on the screw rod, down conversion is steady, gear 2-5,2-8 is designed to the ordinary gear train of different drive ratios respectively, when gear 2-5 work, driving has the forward transmission nut cover 2-2 rotation of driven driving cog 2-4, thereby drive screw 2-1 is up, oil pump oil pumping work; As gear 2-8 running transmission intermediate drive gear 2-7, intermediate drive gear 2-7 transmission has the reverse drive nut sleeve 2-3 rotation of driven driving cog 2-6, and drive screw 2-1 is descending, oil pump oil suction work.The upper and lower reciprocal operation of screw rod drives the work of oil pumping pump shaft, realizes oil pumping.
When the up oil pump of screw rod is pumped, weight 5 is descended, weight potential energy is discharged the up oil pumping of help screw rod, when screw rod is descending, under the screw rod weight-driven, weight is risen, to the increase of weight potential energy, be to help the up oil pumping storage power of screw rod.
