Description
Technical field:
The utility model relates to used lifting device, especially underground balancing drum long stroke pumping unit in the oil recovery field, oil field.
Background technology:
Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.Conventional at present oil pumper stroke is short, system effectiveness is low, external a lot of research institution has designed the ultra-long-stroke that the broadband type long stroke pumping unit can be realized tens of meters and even hundreds of meters, has limited applying of it but the equilibrium problem of this oil pumper is unresolved always.If do not adopt bascule, then when upstroke, motor need be born whole load, and power hungry is very big; And when down stroke, the energy that rod string discharges is not used.At present the long stroke pumping unit balance method has two kinds: a kind of is the quality of coming the balance rod string by the slip of balance weight and since balance weight slide length can not be very long, this has just limited the stroke of oil pumper.As tower-type friction commutation oil pumper, stroke is long more, and pylon will be high more, and oil pumper maintenance and oil well operation are made troubles; Another kind method is to utilize the very big flywheel of dynamic moment of inertia to store or release energy balance repeatedly, and this method floor space is big, and flywheel is in the process of rotation, because slack rope will appear in the effect of damping and elastic deformation, even the phenomenon that stops operating.
The utility model content:
In order to overcome the short and low deficiency of pay(useful) load rate of stroke that existing oil pumper is brought by equilibrium problem, the utility model provides a kind of underground balancing drum long stroke pumping unit, and this underground balancing drum long stroke pumping unit has underground balancing, stroke is long and the high characteristics of pay(useful) load rate.
The technical solution of the utility model is: this underground balancing drum long stroke pumping unit comprises base, the base middle part is fixed with motor, motor links to each other with switch board by cable, be connected with transmission device on the motor shaft, the base left and right sides is connected with support respectively, and the support upper end is connected with the directive wheel corresponding with transmission device, is connected with the rope chain on the transmission device, rope chain two ends link to each other with polished rod and balance weight respectively by behind the directive wheel, and balance weight places in the balance well.
Base middle part in the such scheme is fixed with motor, motor links to each other with switch board by cable, be connected with cylinder on the motor shaft, the base left and right sides is connected with support respectively, the support upper end is connected with the fixed pulley corresponding with cylinder, be wound with wire rope on the cylinder, the wire rope two ends link to each other with polished rod and balance weight respectively by behind the fixed pulley, and balance weight places in the balance well; The base middle part is fixed with motor, motor links to each other with switch board by cable, be connected with sprocket wheel on the motor shaft, the base left and right sides is connected with support respectively, the support upper end is connected with the jockey sprocket corresponding with sprocket wheel, connection chain under the sprocket wheel, the chain two ends link to each other with polished rod and balance weight respectively by behind the jockey sprocket, and balance weight places in the balance well.
The beneficial effect that the utlity model has is: this underground balancing drum long stroke pumping unit is owing to adopted such scheme, at first balance weight places in the balance well, increased and slided length, reduction pylon height, reduced floor space, thereby solved because of the short problem of equilibrium-limited stroke, increased the oil pumper stroke.Again according to principle of moment balance, thereby oil pumper pay(useful) load rate increases, and improved exercise performance, reduced energy consumption, reduced cost for oil production, helps applying.

The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Embodiment 1:
By Fig. 1 in conjunction with shown in Figure 2, this underground balancing drum long stroke pumping unit comprises base 1, base 1 middle part is fixed with motor 2, motor 2 links to each other with switch board by cable, is connected with cylinder 6 on 2 in the motor, and base 1 left and right sides is connected with support 3 respectively, support 3 upper ends are connected with the fixed pulley 7 corresponding with cylinder 6, be wound with wire rope 8 on the cylinder 6, wire rope 8 two ends link to each other with polished rod and balance weight 4 respectively by behind the fixed pulley 7, and balance weight 4 places in the balance well 5.Cylinder 6 drives forward and reverse rotation by the permanent torque motor 2 of adjustable speed, and wire rope 8 is wrapped on the cylinder, and an end is connected with the polished rod post, and the other end is connected with balance weight 4, and suspension point and balance weight 4 all are submerged in the underground balancing well 5.Be about to balance weight 4 and all be submerged in the underground balancing well 5, lay winding wire ropes 8 on cylinder 6, just changeing by motor 2 that head roll 6 rotatings drive pump plunger and balance weight 4 moves up and down.Motor 2 drives the rotation of cylinder 6 clockwise directions, and wire rope 8 drives sucker rod and moves upward, and finishes upstroke work.This moment, balance weight 4 fell, and helped lifting oil well load.Motor 2 drives cylinder 6 rotation counterclockwise, and wire rope 8 drives sucker rod and moves downward, and finishes down stroke work.This moment, balance weight 4 risings stored energy.This motor 2 can be according to the load of system, and accurately the energy of motor 2 is supplied with in control, with harmful vibration of decay oil pumping system.By adjusting the rotating time and the speed of motor 2, can control up-down stroke running time and length of stroke, thereby have the operation characteristic of long stroke, low moment of torsion, low jig frequency.Slide length, reduction pylon height thereby increased, reduced floor space, solved, increased the oil pumper length of stroke because of the short problem of equilibrium-limited stroke.According to principle of moment balance, the pay(useful) load rate of oil pumper increases again, and exercise performance improves, and energy consumption reduces, and cost for oil production reduces, and helps applying.
