Abstract
The utility model relates to a pumping unit, in particular to a crank-slider type pumping unit. The pumping unit mainly comprises a gearwheel, a pinion, a motor, a crank, a connecting rod and a frame, wherein the gearwheel, the crank and the connecting rod are fixed at the upper end of the frame; the pinion and the motor are fixed at the lower end of the frame; the pinion is meshed with the gearwheel; and the gearwheel drives the connecting rod to move up and down through the crank so as to drive an oil rod which is connected with the connecting rod. The utility model has the advantages that: a sucker rod is driven to reciprocate up and down through the circular motion of the crank, the design layout is compact, the defect of a large structure of an oil beam type pumping unit is overcome, and the pumping unit has the advantages of compact structure, low power, high efficiency and the like.
Description
Technical field:
The utility model relates to a kind of oil pumper, particularly a kind of crank block type pumping unit.
Background technology:
Oil pumper is a kind of machinery equipment of recover petroleum, makes oil go out well through the way of pressurizeing.When the oil pumper upstroke, the oil pipe elastic shrinkage moves upward, and drives mechanical block-relief oil production device and moves upward, and the bump sliding sleeve produces vibration; Simultaneously, the copper current only valve cuts out, and reducing piston assembly shutoff oil is when the oil pumper down stroke, and the oil pipe elastic elongation moves downward, and drives mechanical block-relief oil production device and moves downward, and the bump sliding sleeve produces vibration; Simultaneously, reverse ball-and-seat is partly closed, and the reducing piston assembly is shutoff oil jacket ring shaped oil passage still, makes reverse ball-and-seat lower zone form the higher-pressure region, and this motion produces a kind of reverse impact force to the oil flow channel in the stratum again.Traditional oil pumper has beam pumping unit, chain type oil pump etc., and these oil pumpers are bulky, and floor space is big, and efficient is low, the big deficiency that waits of energy consumption.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of crank block type pumping unit is provided, and it is little to have a volume, compact conformation, and power is little, the efficient advantages of higher.
Its technical scheme is: mainly be made up of gear wheel, pinion, motor, crank, connecting rod, frame; The upper end of described frame is gear wheel, crank and connecting rod fixedly; The lower end of frame is pinion and motor fixedly; The engagement of pinion and gear wheel, gear wheel moves up and down through the crank drivening rod, and then the beam hanger that is connected with connecting rod of drive.
The afterbody of above-mentioned crank is provided with balancing weight.
The beneficial effect of the utility model is: utilize the circular motion of crank to drive pumping of sucker rod, such layout is compact, has avoided the huge drawback of oily girder-like oil pump structure, has compact conformation, and power is little, the efficient advantages of higher.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: gear wheel 1, pinion 2, motor 3, crank 4, connecting rod 5, frame 6, slide block 7, beam hanger 8, well casing 9, packing box 10.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of gear wheel 1, pinion 2, motor 3, crank 4, connecting rod 5, frame 6, slide block 7, beam hanger 8, well casing 9, packing box 10; The upper end of described frame 6 is gear wheel 1, crank 4 and connecting rod 5 fixedly; The lower end of frame 6 is pinion 2 and motor 3 fixedly; Pinion 2 and gear wheel 1 engagement, gear wheel 1 moves up and down through crank 4 drivening rods 5, and then the beam hanger 8 that is connected with connecting rod of drive.
Utilize the circular motion of crank to drive pumping of sucker rod, such layout is compact, has avoided the huge drawback of oily girder-like oil pump structure.Because sucker rod weighs several tons even tens tons, the power of motor that needs is very big, and we can utilize balance weight to solve: the afterbody of crank 4 is provided with balancing weight.In the beam hanger downward stroke, beam hanger drives crank and rotates, and counterweight is moved upward, storage power; In sucker rod moves upward process, the motor acting, counterweight moves downward simultaneously, releases energy.Like this, motor just can be realized the reciprocating motion of sucker rod under the small-power very much.
The required oil pump stroke of different oil wells is different, and the off-centre that we can regulate crank realizes.The rotating speed of oil pumper depends on the downhole oil reserve, and must rationally control could the implementation efficiency maximization.As shown in Figure 1, on behalf of the rotating speed case, I realize the oil pumper speed change with two gears.The gearbox technology of oil pumper and brake system are quite complete, repeat no more here.
In addition, owing to be crank block structure (although can regulate counterweight), can not absolute balance.The huge weight of beam hanger and counterweight must cause very big centrifugal force and to the shearing of crank drive shaft, the requirement of strength to crank shaft is very high like this.In addition, this type of oil pumper receives the restriction of support height and oil well ground installation, and stroke can not be excessive.
Also there is the principle similar with conventional pumping unit in the existing place that is different from conventional pumping unit of the utility model.This new pumping unit is designed with many innovation parts, a kind of brand-new design idea of saying so.After the defective on overcoming some manufacturings and design, must be applied among the actual production.
