Description
Technical field
The utility model belongs to a kind of novel intelligent type energy-saving pumping unit, is applicable to that the mechanical type of oilfield oil well recovers the oil.
Background technology
At present, domestic some oil field block needs the energy-saving pumping unit of long stroke low jig frequency.The conventional pumping unit majority can not meet the demands, and simultaneously there is certain limitation in the balance of conventional pumping unit in the past, and major defect is that energy consumption is big, and stroke, jig frequency can't dynamic adjustments; There is the sealing situation of difficult in reducer.Research and develop running block straight line electricity based on above-mentioned situation and driven oil pumper.
Summary of the invention
The utility model provides a kind of running block straight line electricity to drive oil pumper, the problem that the energy consumption that conventional pumping unit exists is big to solve, stroke, jig frequency can't dynamic adjustments, there is the sealing difficulty in reducer.The technical scheme that the utility model is taked is: support is fixedlyed connected with base, electric winch also is housed on the base, on this electric winch brake is housed, on the fixedly connected base of switch board, cantilever tip is equipped with back guide wheel, middle guide wheel and front jocket wheel cantilever, on the front jocket wheel cantilever front jocket wheel is housed, there is the movable pulley polished rod eye support front, load wire rope one end is fixed on the front jocket wheel cantilever, the other end passes the pulley of movable pulley polished rod eye, walk around front jocket wheel again and be wrapped on the cylinder of electric winch with the back guide wheel, balancing weight is positioned at the inside of support.
In the utility model the front jocket wheel cantilever with the bearing pin of a vertical direction be connected support above, the front jocket wheel cantilever can the bearing pin on vertical direction carry out side to be changeed.
There is drive motors at the two ends of electric winch in the utility model, and mid portion is cylinder, drum shaft and motor coaxle.
The balancing weight upper end connects wire rope in the utility model, and the guide wheel of guide wheel and cantilever tip back was wrapped on the cylinder of electric winch in the middle of the other end of wire rope was walked around, and its winding direction is opposite with the winding direction of load wire rope.
The utility model utilizes the movable pulley principle, required drive is decomposed, reduces in load, and employing electric winch and movable pulley polished rod eye, directly drive polished rod and do rectilinear motion, and can carry out that any jig frequency is regulated, that increase and decrease hanging balancing balancing weight improves parts is stressed and rationally mate the up-down stroke time.The power of electric winch output, reciprocating motion by the movable pulley polished rod eye, drive polished rod and do rectilinear motion up and down reciprocatingly, when upstroke, ballast box does work to polished rod by the movable pulley polished rod eye with electric winch, switch board quickens to adjust to electric winch simultaneously, finishes the pumping of downhole pump plunger.During down stroke, to ballast box acting, switch board is finished the return of oil pump plunger piston to the electric winch adjustment of slowing down to electric winch simultaneously with polished rod.By electron controls technology, electric winch is carried out dynamic speed adjustment, realize fast slow pumping work down on the oil pumper.This is just meeting the load change of rod-pumped well, can also improve the stressed situation of sucker rod simultaneously.
The utility model has the advantages that: novel structure, adopt the movable pulley polished rod eye, guarantee to have reduced required drive exponentially under the constant situation of hoisting power.Dynamically adjust the electric winch rotating speed, but step-less adjustment oil pumper jig frequency.Can dynamically regulate the upper and lower stroke speed of oil pumper and realize energy-saving and production-increase.Oil pumper has been carried out soft start, and starting current reduces significantly, avoids oil pumper is produced excessive mechanical shock, prolongs service life of equipment.Have multinomial defencive functions such as overvoltage, under-voltage, overload, short circuit, phase shortage, electric leakage and stall, the more accurate electric winch of protecting reliably.Reduce required drive, have higher energy-saving effect, dynamic speed adjustment, simple to operate, reliable operation, not only energy conservation has improved operating efficiency again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
In the utility model the bearing pin of a vertical direction of front jocket wheel cantilever 9 usefulness be connected support (5) above, front jocket wheel cantilever 9 can the bearing pin on vertical direction carry out side to be changeed.
There is drive motors at the two ends of electric winch in the utility model, and mid portion is cylinder, drum shaft and motor coaxle.
Balancing weight 6 upper ends connect wire rope 4 in the utility model, and the guide wheel 14 of guide wheel 8 and cantilever tip back was wrapped on the cylinder of electric winch 3 in the middle of the other end of wire rope 4 was walked around, and its winding direction is opposite with the winding direction of load wire rope 11.
During work, under the reciprocal turning effort of electric winch 3, with power by wire rope transfers to the movable pulley polished rod eye, make the movable pulley polished rod eye drive polished rod and make rectilinear motion up and down reciprocatingly; Simultaneously, under the effect of electric winch, moving linearly up and down reciprocatingly is because reaction force that its deadweight produces winch drum by wire rope for balancing weight, all the time to be applied to the moment of cylinder opposite with the load cable of movable pulley polished rod eye, therefore plays balanced loaded effect.How much can adjusting at any time of balancing weight according to actual conditions.
The brake of this machine is installed on the shell of the two ends of electric winch 3----drive motors.The mode that adopts the electromagnetism main brake to combine with the mechanical type auxiliary brake, outage is promptly stopped; Brake torque is big, and is safe and reliable.
