Description
The utility model relates to a kind of double-stranded bar long stroke pumping unit in ground that is used for the oilfield exploitation oil.
At present, the chain drive pumping unit that recovers the oil and use in oil field, China various places is commonly strand bar pumping unit, and its shortcoming is the traction of path chain single file cantilever force, and scroll wheel and guide rail that round frame guide rail bears sideway torque, round frame are easy to impaired.The friction of crosshead shoe reversing arrangement is big, and it is dumb to commutate, and the path chain load is increased, and the rapid wear link increases, amount of maintenance increases, maintenance expenses increases.Its pneumatic counterbalance system adopts formations such as cylinder, plunger, gas holder, inflating pump, and component are various, volume is big, heavy, has increased the energy consumption that produces greatly because of rubbing, and influences the working life of pumping unit.
The purpose of this utility model be to avoid above-mentioned deficiency of the prior art and provide that a kind of floor space is little, in light weight, life-span length, reliable big load, the double-stranded bar pumping unit of long stroke.
The purpose of this utility model is achieved by the following technical solution: double-stranded bar long stroke pumping unit, comprise motor, drivign belt, speed reducer and chain drive, wherein, chain drive is double-stranded bar transmission, and the sprocket wheel on its axis is by chain coupling semiaxis cantilever sprocket wheel, track lower sprocket; The track lower sprocket connects the track upper sprocket wheel by the duplicate rows path chain; Be fixedly connected with the axle of passing a bridge on the duplicate rows path chain; Gap bridge axle top connects the wire rope of rope hanger, and the bottom connects the counterweight chain, and the counterweight chain is hung with counterweight through two commutation sprocket wheels.
In addition, track upper sprocket wheel and track lower sprocket spacing range are 5～7 meters.
The utility model compared with prior art has following advantage:
1, double-stranded bar is lifted the traction gap bridge axle of shoulder pole formula, has improved the chain stressing conditions, has alleviated the load of chain, has improved its working life.
2, the component of round frame and scroll wheel thereof, guide rail, commutation crosshead shoe and pneumatic counterbalance system have been removed, alleviated weight greatly, reduced fragile part, reduced the energy consumption that produces greatly because of rubbing, thereby the life-span and the efficient of pumping unit have been improved, reduce cost convenient for maintaining and reduced maintenance expenses.
3, changing air-balance is counterweigh, improved leakage because of pressurized gas, piston in different strokes gas compression than the fluctuation of different formed equilibrant; Change the adjustment counterweight by electric current in the electric control cubicle, make stroke load balancing up and down, it is minimum that current fluctuation reaches, and reaches purpose of energy saving.Relay protection meeting in electric control cubicle outage automatically shuts down motor, and is safe and reliable.
4, can adjust stroke length by track sprocket wheel spacing about adjusting, avoid the prior art pumping unit to increase stroke, each several part will increase in proportion, the shortcoming that floor space increases.Under the situation of variable ratio not, along with stroke longer, jig frequency is corresponding to be reduced.Be easy to change stroke and jig frequency.
5, the utility model floor space is little, and it is big to bear load, and efficient height, commutation are gently, and be reliable.The needs of particularly suitable sea and land cluster well and thickened oil recovery are the novel preferred equipments of oil field intermediary and later stages recover petroleum.
Description of drawings
Fig. 1 is the plan view of the utility model structural representation;
Fig. 2 is the left view of the utility model structural representation;
The utility model is described in further detail below in conjunction with drawings and Examples: double-stranded bar long stroke pumping unit mainly is made of by movable sprocket 7, dual trace sprocket wheel 8,17 and main chain bar 6, dual trace chain 9, the axle 10 of passing a bridge, rope hanger 11, crown sheave 12, commutation sprocket wheel 13,15, counterweight chain 14, counterweight 16 etc. frame 1, motor 2, speed reducer 3, axis 5, drive sprocket 4, semiaxis.The motor 2 that is installed on frame 1 base connects speed reducer 3 by belt, belt pulley, the output shaft of speed reducer 3 directly connects chain drive-belt axis 5, its chain drive is double-stranded bar transmission, be fixed with two main drive sprockets 4 on its axis 5, sprocket wheel 4 is by initiatively chain 6 and semiaxis cantilever are guaranteed the steadily commutation successfully of gap bridge spindle unit by the space of the transmission of movable sprocket 7 and formation thereof.With sprocket wheel 7 with being fixed with (two groups of track lower sprockets 8 on the semiaxis, duplicate rows), duplicate rows path chain 9 connects track upper sprocket wheel 17 and track lower sprocket 8, can adjust stroke length by track sprocket wheel spacing about adjusting, manufacturing is greater than the pumping unit of 7.5 meters strokes, needn't increase the length and width of frame 1, as long as increase equal height by the stroke longer amount.Adjust jig frequency on a large scale as needs, the belt pulley of replaceable motor 2 and speed reducer 3.Duplicate rows path chain 9 is lifted the traction gap bridge axle 10 of shoulder pole formula, axle 10 natural commutations along with path chain 9 unidirectional rotary motions of passing a bridge.The wire rope 18 of the rope hanger 11 of crown sheave 12 is passed through in the axle 10 tops connection of passing a bridge, and the bottom connects counterweight chain 14, and counterweight chain 14 is hung with counterweight 16 through two commutation sprocket wheels 15 and sprocket wheel 13.The load such as fluid column that rope hanger 11 is being born sucker rod, deep-well pump and is being raised, this load and counterweight 16 be balance on the axle 10 of passing a bridge, counterweigh changes by electric current in the electric control cubicle that connects with motor 2, can measure the variation of pumping unit load in stroke up and down exactly, make stroke load balancing up and down by adjusting counterweight.By the relay protection in the electric control cubicle, as take out bar and meet card or rope hanger or counterweight chain card or break, current of electric fluctuate greater than adjustment range, and the relay protection meeting is cut off the power supply automatically motor is shut down in the electric control cubicle.
Working principle of the present utility model: the power of motor 2 is delivered to speed reducer 3 by belt, chain drive-belt axis 5, main drive sprocket 4 on the axis 5 drives by chain 6 and is rotated by movable sprocket 7, rotate synchronously with sprocket wheel 7 with the track lower sprocket 8 of sprocket wheel 7, drive duplicate rows path chain 9 and be synchronized with the movement by track upper sprocket wheel 17 with semiaxis.The load of rope hanger 11 and counterweight 16 be balance on the axle 10 of passing a bridge.Dual trace chain 9 is lifted the axle 10 of passing a bridge that driving of shoulder pole formula, axle 10 load of carrying after being balanced of passing a bridge along with path chain 9 unidirectional rotary motions, arrive the lower end of the upper end of track upper sprocket wheel 17 and lower sprocket 8 and natural commutation, thereby reciprocating, finish the main movement of pumping unit.
