Description

Two traction oil pumpers
Technical field
The present invention relates to a kind of petroleum machinery, oil pumper that especially can energy conservation.
Background technology
Present known beam pumping unit still is to be invented from pressgang gold (lifkin) by the American before more than 120 year, because this oil pumper is sturdy durable, and extensive management; So in the oil exploitation process, use so far always, still along with the strategic demand of development of modern science and technology and energy conservation, the existing energy consumption of this type oil pumper is high; Volume is big; Consumptive material is many, and mechanism is complicated, transfers the defective of joining difficulty and can not be applied to long stroke, low jig frequency, thickened oil recovery occasion progressively to show especially out; Undoubtedly, traditional beam pumping unit has received unprecedented technological challenge.Under this situation, scientific and technical personnel have developed multiple no beam pumping unit, like belt oil pumping machine, and linear motor oil pumping machine, tower-type oil extractor with external rotor electric machine, friction switching-over oil pumper etc.Say that objectively these no beam pumping units all have technological progress to a certain degree, and are more energy-conservation; And can be applied to long stroke, low jig frequency, little pump and take out deeply; The occasion of big pump extract, bigger but above-mentioned multiple no beam pumping unit motor is equipped with power, manufacturing cost is high; Power savings is not remarkable, and gentle rope such as belt, wire rope is short application life.
Summary of the invention
In order to overcome the above-mentioned deficiency of traditional beam pumping unit and no beam pumping unit; The present invention provides two traction oil pumpers, and this type oil pumper not only can satisfy the crude oil suction of various hole conditions, and power disposition reduces significantly; Energy conservation more; Simultaneously, prolong application lifes such as belt, wire rope, chain greatly, and safety factor has also had large increase.
The technical solution adopted for the present invention to solve the technical problems is: two traction oil pumpers are mainly by upper mounting plate 1, motor and cylinder 2, front jocket wheel 3, strap 4,11,12, polished rod clamp 5; Polished rod eye 6, polished rod 7, well head 8, frame 9; Main counterweight 10, middle guide wheel 13, secondary counterweight 14, switch board 15 constitutes.Constitute the oil pumper carrier by frame 9 and upper mounting plate 1; Motor and cylinder 2, front jocket wheel 3 are set on upper mounting plate 1, and an end of strap 4 is fixed by bolts on motor and the cylinder 2, links with polished rod eye 6 after the other end is walked around from front jocket wheel 3 again; Polished rod 7 stretches out from well head 8 centers with polished rod eye 6 usefulness polished rod clamps 5 and is connected; The upper end of strap 11 is fixed on motor and the cylinder 2, and the other end and main counterweight 10 link, so far; Constitute the main trailer system of oil pumper, it utilizes the elevator mode to draw suspending point loading through motor and cylinder 2.Guide wheel 13 between the motor of upper mounting plate 1 and cylinder 2 and guide wheel 3, being provided with; Walk around middle guide wheel 13 with strap 12, front jocket wheel 3, front end and polished rod eye 6 are connected; Rear end and secondary counterweight 14 are connected; So far, constituted the secondary trailer system of oil pumper, it is to utilize the gravity draw mode of the secondary counterweight of reactive loss to draw suspending point loading.Said strap is belt or wire rope or chain.Said motor is switched reluctance machines or rare earth permanent-magnet synchronization motor.
After motor and cylinder 2 energising rotations (be made as and rotate counterclockwise); Strap 4 is through Electrical machinery cylinder 2 elevators; Traction front side suspending point loading moves to top dead centre, and to the lower dead center operation, gradually relax control on cylinder by strap 11 under action of gravity for rear side master counterweight; Meanwhile; Secondary counterweight 14 under the self gravitation effect, haul strap 12 through in guide wheel 13 and front jocket wheel 3, draw high top dead centre to the front side suspending point loading from lower dead center with motor and cylinder 2, main counterweight 10, thereby drive polished rod 7 drive oil well pumps are drawn into ground to underground crude oil with withing joint efforts.After motor and cylinder 2 switching-over rotations (clockwise rotating), to the lower dead center operation, strap 4 is along with motor and cylinder 2 rotations under its action of gravity for polished rod and roofbolt, fluid column; Dragging suspending point loading and moving to lower dead center, main counterweight 10 is along with strap 11 moves to top dead centre through motor and cylinder 2 elevators, meanwhile; Suspending point loading hauls strap 12 secondary counterweight 14 is promoted to top dead centre; Until it is risen to top dead centre, store gravitation energy, for following one-stroke is prepared.
Obviously; Secondary counterweight is set, suspending point loading is rationally decomposed, bear respectively by main counterweight and secondary counterweight; And secondary counterweight participates in drawing high not consuming any energy source of suspending point loading; But utilize self gravity work production, just that suspension point self is intrinsic weight is taped the latent power, and becomes available gravity work production.
Existing is example with 14 the most frequently used type oil pumpers of oil field, further specifies the effect that secondary trailer system is installed.When working, general 14 type oil pumpers from indicator card, can see maximum load 100KN when suspension point rises, minimum load 60KN when suspension point descends.When secondary counterweight was not set, main counterweight was generally 80KN, the average of promptly maximum suspending point loading and minimum suspending point loading; Oil pumper is in when operation, and when motor and cylinder rotated counterclockwise, motor front side suspending point loading was toward the top dead centre operation; Load is 100KN, and main counterweight is 80KN, and motor is born 20KN, and (frictional force is ignored; Down together), rise to top dead centre to suspending point loading from lower dead center, oil well pump is accomplished oil pumping process.When motor and cylinder clockwise rotated, suspending point loading was 60KN, and main counterweight is 80KN, and motor equally also is to bear 20KN, transfers to lower dead center to suspending point loading from top dead centre, and oil well pump is accomplished oil-filled process.If diameter of cylinder is 1000mm, the moment of torsion of motor and cylinder output during upstroke, the front side is: 100KN * 1000/2=50KNm, rear side is: 80KN * 1000/2=40KNm.
After having increased secondary counterweight, analyze the stressing conditions on motor and the cylinder again, suppose that the front side suspending point loading is still constant; Secondary counterweight is 50KN, and main counterweight is 30KN, and both sums still are 80KN; When motor and cylinder rotate counterclockwise, at first secondary counterweight utilizes self gravitation that the suspension point maximum load has been born 50KN, remaining 50KN; Born 30KN by main counterweight, motor and cylinder are born 20KN again, just suspending point loading are mentioned top dead centre from lower dead center.When motor and cylinder clockwise rotate; Suspension point minimum load 60KN; Rely on it can secondary counterweight 50KN be mentioned, but because main traction is still being dragged, suspending point loading can not be descending easily; Still will rely on motor and cylinder to bear 20KN, the gravity that overcomes main counterweight 30KN could be transferred to lower dead center with suspending point loading.
After secondary counterweight is set, the moment of torsion of dissection on motor and cylinder again, during upstroke, the front side is: (100-50) * and 1000/2=25KNm, rear side is: 30 * 1000/2=15KNm.
Compare before and after setting up secondary counterweight, front side: 50KNm-25KNm=25KNm, rear side: 40KNm-15KNm=25KNm, front side moment of torsion reduce by 25 ÷ 50=50%, and the rear side moment of torsion reduces by 25 ÷ 40=62.5%.Obviously, the moment of torsion that acts on motor and the cylinder reduces 50-62.5%.
The invention has the beneficial effects as follows: at first be energy-conservation,, can reduce Motor torque 50-62.5%, secondly, make things convenient for the shaft mouth operation load removal through aforementioned calculation; The 3rd, because load decomposition prolongs the application life of strap to major and minor two trailer systems greatly, the 4th, owing to increased secondary trailer system; Increased safety factor, be unlikely flexible strap and fracture simultaneously, safer, more insurance; The 5th, reduce the motor nominal torque, it is little that the rating of electric machine is fallen, and then reduce manufacturing cost.
