Description
Technical field
The utility model is a kind of multi-stage speed-reducing short chain gearing vertical pumping unit without general speed reducer, belongs to electromechanical integration
New application.
Background technology
In oil field development, traditional double leval jib beam pumping unit is most important exploitation means.According to incompletely statistics, entirely
There is more than 600 ten thousand mouthfuls of mechanical oil well in the world at present, and double leval jib beam pumping unit accounts for 90% or so, becomes the master of mechanical oil recovery
Lead type.
The tired reality of double leval jib beam pumping unit is durable, lasting over 100 years.But with scientific and technological progress and green energy resource
It is required that the traditional transmission mode technology for continuing to use nearly 2nd century has already fallen behind, following technical bottleneck restricts the hair of this kind of type
Exhibition, it would be highly desirable to carry out technological innovation.
First, transmission chain length, system effectiveness are low
Double leval jib beam pumping unit from motor output power to complete oil pumping cycle, by motor → small belt pulley →
Three axis → 2 crank of belt → big belt pulley → one axis of reduction box → two axis of reduction box → reduction box → → 2 connecting rods → horizontal rafter
Nearly 30 transmission parts of the overlength driving-chains such as → tail bearing → walking beam → middle (center) bearing → horse head → hair plait, system effectiveness≤
40%.
Second is that low load with strong power highly energy-consuming phenomenon protrudes, national industrial policies are not met
Double leval jib beam pumping unit is commutated using double leval jib, crank spin balancing.Due to this kind of motion mode theoretically
It can not realize preferable balancing effect, polished rod load, counterbalance effect and torque curve are in sinusoidal motion with crank rotation angle
There is 0 value twice, a peak positive value, a trough negative value, torque operating mode evil in rule, an oil pumping circulation torque
It is bad, motor is configured by 3-5 times of declared working condition in power configuration design, low load with strong power phenomenon is serious.At present, according to state
The energy-saving and environment-friendly industrial policy of family, highly energy-consuming equipment have been included in superseded ranks.
Third, dangerous point source is more, ginseng trouble is adjusted, maintenance workload is heavy
There are congenital dangerous point source in the crank rotating mechanism design of double leval jib beam pumping unit, there is hair in when casualty accident
It is raw.Stroke parameters adjustment must be by means of crane, and by knack worker, time-consuming and laborious high labor intensity is just in hazardous environment
It can complete, not meet health, safe and environment-friendly requirement.
For above-mentioned limitation of the technology bottleneck, the applicant was proposed before 40 years without any intermediate transmission link, only by separate unit
Motor drives, and realizes the vertical oil-pumping machine designing scheme of preferable Balance effect and the commutation of 0 electric current, declares and obtain successively
National patent (00246414.4,02257259.7,200510123422.9), and demonstrate theoretical and scene with model machine and answer
Feasibility.
The announcement and implementation of foregoing invention innovation cause the Domino effect in pumping unit field, domestic numerous and confused appearance immediately
A variety of imitate plagiarizes type.Although all kinds of its structure of imitation type and principle without prominent substantive distinguishing features and significantly into
Step, but from the angle of Optimal improvements, it may have certain reference value.
Compared with traditional double leval jib beam pumping unit, the above-mentioned energy saving material saving of electric-machine directly-driven Balance vertical oil-pumping machine
30-60%, does not shut down intelligence ginseng is adjusted to improve work efficiency and be more than 1000 times, and maintenance workload reduces more than 60%, suitable for long stroke, low
The working system of jig frequency, these apparent technical advantages determine electric-machine directly-driven Balance vertical oil-pumping machine tradition substituted greatly
The development trend of double leval jib beam pumping unit.But the development course of nearly 40 years pumping units is summarized, technical advantage is so apparent
Electric-machine directly-driven Balance vertical oil-pumping machine remains in the small-scale trial period, fails to take out traditional double leval jib beam type always
Oil machine replaces, and crux is：
First, pumping unit is a kind of heavy field mining site machinery of low-speed big, it is big that single motor directly drives required low speed
Torque certainly will will increase motor volume and power, and manufacture cost remains high, and makes manufactory and Oil Field are all uncomfortable to hold
By.
Second is that operation step down, unloading hang take out, lose carry protection be vertical oil-pumping machine fault of construction, it is necessary to carry out breakthrough wound
Newly.
Increase square third, increasing general speed reducer and realizing to slow down, be returned to long chaindriven old road, increase assembly difficulty and
Cost reduces efficiency, adds maintenance workload.
Above-mentioned three technology bottleneck, constrains the development of electric-machine directly-driven Balance vertical oil-pumping machine, it would be highly desirable to Continuous Innovation,
It is allowed to be more suitable for live practical application, forms substituted technical advantage.
Single motor is only leaned on to realize low-speed big driving, except trying to reduce torque needed for motor driving load reduction,
In addition seek to improve the torque being output in load drive shaft as far as possible.This will build the short structural mechanics of following high-efficiency precision
Model simultaneously carries out rational mechanics verification.
One, tower Balance effects are the key that reduce driving torque
In tubing pump pumping production, up stroke maximum load is equal to fluid column load Wf, roofbolt load Wr, dynamic loading
Wrα, frictional force FfThe sum of subtract buoyancy Fb, i.e.,：
Maximum load=Wf+Wr(1+α)+Ff-Fb
Down stroke minimum load is roofbolt load WrSubtract dynamic loading Wrα and buoyancy FbAnd frictional force FfThe sum of, i.e.,：
Minimum load=Wr(1-α)-(Fb+Ff)
Due to the difference of the polished rod load of upper and lower stroke, if without appropriate balance, motor must be complete in up stroke
Into whole Effective powers, and in down stroke, due to gravity, minimum load drive motor is slided, this must just use big work(
The motor and deceleration device of rate, while its efficiency is also very poor.It is high caused by order to solve the serious imbalance of stroke load up and down
Energy consumption, high material-consumption and low efficiency problem, it is necessary to be aided with appropriate balance.The average load of upper and lower stroke is " preferably balance
Effect " is：
(CI)=1/2 (maximum load+minimum load)
=1/2 [Wf+Wr(1+g)+Wr(1-g)-2Fb]
=Wf/2+Wr-Fb
Then in upstroke, when lifting the combination weight of buoyant sucker rod and liquid, motor can obtain this
As a result the help of equilibrant force only needs to drive half W for being equivalent to liquid weightf/ 2 out-of-balance force.It is buoyant during down stroke
Sucker rod downlink, can be subject to the impedance of equilibrant force, as a result there remains half W for being equivalent to liquid weightf/ 2 out-of-balance force is by electricity
Motivation is completed.It is verified through theoretical calculation and mining site, Wf/ 2 are only equivalent to 20% of maximum load or so, and this greatly reduces electricity
The increasing productivity of motivation, so as to reduce the output torque of motor simultaneously and then reduce the matched power of motor.
Two, motors " 0 " electric currents, which commutate, has overthrown the design concept of low load with strong power, realizes vehicle and horse Optimized Matching
Electric motor starting electric current is generally 3-5 times of rated current, and tower-type Balance vertical oil-pumping machine exactly needs
Motor frequent starting realizes commutation, this is just bound to cause the short-lived and highly energy-consuming of motor, uses the power configuration of low load with strong power
Realize acting requirement.But the switch mechanism of vertical oil-pumping machine sucker rod pumping travelling valve dexterously avoids commutation moment electricity
The drawbacks of machine great start-up current, realizes the commutation of 0 electric current.
When sucker rod goes upward to the moment of top dead-centre motor stopping commutation, the combination weight of well head side sucker rod and liquid is remote
More than the balance amount of stressing, the as a result combination weight of well head side sucker rod and liquid meeting dragging motor is rotated and driven in balance weight
Row, but commutation action is completed moment, and underground travelling valve is opened, and well head side liquid weight unloads immediately, and the well head amount of stressing is no longer
, it is necessary to which motor help drives balance weight can just be made to continue uplink more than the balance amount of stressing, then motor is ingeniously borrowed and taken out by well head side
The inertia turn-on power of taking advantage of a situation of 0 electric current of combination weight of beam hanger and liquid dragging normally does work.When sucker rod comes downwards to bottom dead centre
Motor stopping commutates moment, and the balance amount of stressing is much larger than the well head amount of stressing, direct 0 electric current of the dragging motor commutation of balance weight, commutation
Moment travelling valve is closed, sucker rod carry, and the balance amount of stressing is no larger than the well head amount of stressing, and then motor is ingeniously borrowed and has been balanced
The inertia dragged again is taken advantage of a situation conducting, is completed the 0 electric current commutation of motor frequent starting, has fundamentally been overthrown setting for low load with strong power
Meter theory realizes vehicle and horse Optimized Matching.
Three, realize that multi-stage speed-reducing increases the technological approaches of square without general speed reducer
For pumping unit, even if being designed by maximum running parameter, such as 8 meters of stroke, jig frequency 4 times, motor it is specified
1000 revs/min of rotating speed, is transformed on load output wheel, it is only necessary to 40 revs/min.This usually require set big retarding than speed reducer
Deceleration transmission.
No general speed reducer can not realize that multi-stage speed-reducing is driven.Highly efficient multi-stage speed-reducing short chain can be optimized to pass
Dynamic model formula.
First, according to Mechanics of Machinery engineering calculation formulas, power is equal to torque and the product of rotating speed removes 9550, i.e.,：P=T
×n/9550。
Obviously, under the certain operating mode of power of motor, to realize large torque, rotating speed n is greatly lowered, can significantly carry
High torque T.This, which is equivalent to, realizes the primary speed-down increasing square that motor itself significantly slows down.
Second is that load drive shaft and motor output shaft are set into big steamboat transmission, it can be achieved that double reduction increases square.
Third, the laborsaving half of movable pulley can make the torque of load drive shaft reduce half.But work(principle is not saved due to laborsaving,
Movable pulley carry movement velocity reduces half, this, which is equivalent to, realizes three-level deceleration.
Using above-mentioned tower Balance, significantly off-load drop square, engine, big steamboat transmission double reduction increase square, move and slide
Off-load drop square combination transmission is taken turns, is to have built preferable theoretical plates without general speed reducer multi-stage speed-reducing short chain gearing vertical machine.
