The operating principle that the low-speed big special-shape motor drags high-efficiency low-consumption intelligent pumping unit is:
The low-speed big special-shape motor drags high-efficiency low-consumption intelligent pumping unit and has broken through the operation logic of all oil pumpers up to now, and the outer rotor that relies on the low-speed big special-shape motor is with the friction mode transfer torque; Forward and reverse rotation of motor is converted to the up-and-down movement of sucker rod by the digital intelligent control device; The flexible balance mode of gravity and elastic band combined type balance can be realized optimum balance; The digital intelligent control device also can be adjusted rotating speed of motor according to the in good time intelligent stepless of oil well liquid-supplying situation, turns to, torque, realize dynamic coordinate with the stratum fluid supply capacity with the best fit of working systems such as stroke, jig frequency, efficient, low consumption, realize the pumping circulation of oil pumper intelligently.
The technical solution that the low-speed big special-shape motor drags high-efficiency low-consumption intelligent pumping unit is:
This oil pumper is shaped as tower tube or pylon shape, the motor (18) at tower tube (3) top is an outer-rotor structure, the position of each component and annexation are complete machine with bolt on oil pumping unit base (1), base (1) top successively fixed tower tube base (2), moving device (23), digital intelligent control device (22), tower tube (3), tower tube roof panel (13), motor base (14), guardrail (15), safeguard support (16), generator (17), motor (18); Hold load lifting band (10) on motor (18) the outer rotor strip winding cylinder (41), load lifting band (10) one ends are sling device (8) fixedly, the other end connects the tandem-driving bogie (7) in the tower tube (3), tandem-driving bogie (7) top connects protection rope (9), and the bottom connects elastic band (5) and safety rope (6); Tower tube (3) inside lower end is welded crashproof bearing (4), and tandem-driving bogie is set upright rope (19) and is fixed on tower tube base (2) and the tower tube roof panel (13) by the tandem-driving bogie righting hole; Weld stiffener on tower tube (3) outside tower tube base (2) and under the tower tube roof panel (13), axially weld reinforcing rib, the control cables of upper and lower dead point sensor (20), (21) and power supply and other control cables are connected in the digital intelligent control device (22) by hollow reinforcing rib; Digital intelligent control device (22) and tandem-driving bogie (7) security door and loading and unloading balance weight manhole are opened in the outer side-lower of tower tube (3) both sides; Welding winding staircase (11) to tower tube roof panel skylight (12) on the tower tube base (2) locates.Complete machine by digital intelligent control device (22) adjust in good time the special-shaped motor of low-speed big (18) rotating speed, turn to, torque, thereby drag high-efficiency low-consumption intelligent pumping unit with the big up and down stroke linear reciprocating motion of the most rational swabbing parameter of coupling, realize oil pumping circulation and efficient low-consume purpose of energy saving.In the less oil pumper of matched power, even can be aided with supporting electric capacity, batteries and fairing, form what is called " perpetual motion machinery " by the acting of oil pumper self power generation systemic circulation.
On human sciences's history, after the mechanics philosophy was established, after especially electromagnetic theory was found, just the someone was devoted to the research of perpetua mobilia.Though the futile effort of this idiotic nonsense research by scientific circles qualitative be pseudoscience, but the object of the permanent motion of nature is not rare, motion as celestial body, the variation of morning and evening tides, the earth of our life just just with more than 1600 kilometer speed per hour in rotation around the clock unconsciously and around sun revolution.This permanent motion (though might disappear in unpredictalbe future remote) that does not apply external force or makeup energy artificially and lean on natural force to produce can be called " perpetual motion " fully.The utility model just utilizes oil pumper up storage of potential energy of sucker rod in the pumping process, the descending release kinetic energy of balance weight, and the up storage of potential energy of balance weight, the principle of the descending release kinetic energy of sucker rod circular work, drive generator for electricity generation with friction mode, form and do the major drive, then change stand-by heat over to system power supply, by " the perpetual motion machinery " of oil pumper self power generation systemic circulation acting (in battery life in the cycle), its circular work process is as follows:
The low-speed big special-shape motor drags that high-efficiency low-consumption intelligent pumping unit is efficient, low consumption, Energy saving mechanism are:
High efficiency mechanism:
Because the low-speed big special-shape motor drags high-efficiency low-consumption intelligent pumping unit and adopts high tower tube (3) and motor (18) and load lifting band (10) frictional drive structure, can increase length of stroke to greatest extent, reduces the pump efficiency that reduces because of loss of plunger stroke.According to pump efficiency loss formula of reduction η=λ/h, under certain load, its loss of plunger stroke λ is a constant, thereby stroke h is long more, and η is more little in the pump efficiency loss, and promptly actual pump efficiency is high more.Compare with classical four connecting rods trip trip machine, average pump efficiency can improve 5-10%.In addition, its digital intelligent control device (22) can be at random to rotating speed, turn to, torque, acceleration carry out comprehensive in good time control, make running of ground power and underground equipment and feed flow situation obtain optimal dynamic and coordinate, more classical four connecting rods trip trip machine improves system effectiveness more than 15%.
Low consumption mechanism:
Because dragging high-efficiency low-consumption intelligent pumping unit, the low-speed big special-shape motor adopt motor (18) outer rotor to make drive system; an outer rotor has been realized prime mover; transmission device; speed change gear; reversing arrangement; bascule; check mechanism; protective device; TRT one machine eight usefulness; saved the motor small belt pulley of conventional four connecting-rod beam machines; driving belt; big belt pulley; three reduction boxes; the reduction box base; crank-pin; crank; connecting rod; horizontal rafter; the tailing axle assembly; walking beam; the axis assembly; nearly 20 parts such as horse head; compare with the same specification type, more conventional four connecting-rod beam machines are saved steel 50-60%.Under digital intelligent control device (22) is regulated and control at random in good time, complete machine is in optimization state operation down at a slow speed, alleviate the impact load and the lack of uniformity that occur in the various mechanical switch links greatly, improved the equipment operation situation, prolonged each moving component running life more than 100 times.Carrying, installation, maintenance save time, laborsaving, province's material, belong to round-the-clock non-maintaining type.
Energy saving mechanism:
1. " desirable balancing effect " W
f/ 2+Wz balances out most of lifting load, and motor only need overcome W
f/ 2 out-of-balance force work done, thus significantly reduced the matched power of motor
In tubing pump pumping production device, its up stroke peak load equals fluid column load (W
f), roofbolt load (Wr), dynamic loading (Wr α), frictional force (F
f) sum deducts buoyancy (F
b), that is:
Peak load=W
f+ Wr (1+ α)+F
f-F
bThe down stroke minimum load equals roofbolt load (Wr) and deducts dynamic loading (Wr α) and buoyancy (F
b) and frictional force (F
f) sum, that is:
Minimum load=Wr (1-α)-(F
b+ F
fIf) there is not suitable balance, then motor must be finished all effectively merit at up stroke, and at down stroke, because action of gravity, the minimum load drive motor is slided, and this just must use powerful motor and deceleration device, and its efficient is also very poor simultaneously.High energy consumption, high material-consumption and low efficiency problem for the serious imbalance of stroke load about solving causes must be aided with suitable balance.The average load of stroke is that " desirable balancing effect " is up and down:
(CI)=1/2 (peak load+minimum load)
＝1/2[W
f+Wr(1+α)+Wr(1-α)-2F
b]
=W
f/ 2+Wr-F
bIf the weight of sucker rod in liquid is represented with Wz, then " desirable balancing effect " formula can be reduced to: CI=W
f/ 2+Wz.So in upstroke, when the combination weight of buoyant sucker rod of lifting and liquid, motor can obtain the help of this equilibrant force, the result only needs the out-of-balance force partly that is equivalent to the liquid weight, that is: (a Wz+W
f)-(Wz+W
f/ 2)=W
f/ 2.During down stroke, buoyant sucker rod is descending, can be subjected to the impedance of equilibrant force, and the out-of-balance force partly that the also surplus next one of result is equivalent to the liquid weight is finished by motor, that is: (Wz++W
f/ 2)-Wz=W
f/ 2.Calculate W through theory
f/ 2 are equivalent to about 17% of peak load, and this has just significantly reduced the lifting load of motor, thereby reduce the matched power of motor.
2. the wheel shaft type of drive can obtain R/r mechanical advantage doubly, has further reduced the lifting load of motor
The outer rotor that the low-speed big special-shape motor drags high-efficiency low-consumption intelligent pumping unit is a major diameter wheel shaft, and its ratio design of taking turns radius R and axle radius r is greater than 1.6.According to the wheel shaft principle, its mechanical advantage is P/F=R/r, and tangentially power F is always less than axle lifting load P because R always greater than r, therefore takes turns, and then the lifting load of motor actual needs driving has only F=Pr/R=W
fR/2R=W
f/ 3.2.The theoretical W that calculates
f/ 3.2 are equivalent to about 10% of peak load, and this has further reduced the lifting load of motor again.
3. driving-chain simplifies 86%, has significantly reduced mechanical loss, improves mechanical efficiency more than 15%
Conventional four connecting-rod beam machine driving-chains are by motor output shaft → small belt pulley → belt → big belt pulley → one-level gear → secondary gear → tertiary gear → crank (pin) → connecting rod → horizontal rafter → tailing axle → walking beam → axis → horse head → hair plait totally 15 links, 7 groups of bearing frictions, mechanical efficiency is lower than 75%.And dragging the high-efficiency low-consumption intelligent pumping unit driving-chain, the low-speed big special-shape motor has only motor outer rotor → 2 links of load lifting band, 1 group of bearing friction, the more conventional four connecting-rod beam machines of driving-chain have reduced 86%, bearing friction has reduced 86%, mechanical efficiency is higher than 90%, improves mechanical efficiency more than 15% than conventional four connecting-rod beam machines.
4. Fei Lun Inertia effect and motor commutation are shut down economize on electricity 20%
Because dragging high-efficiency low-consumption intelligent pumping unit, the low-speed big special-shape motor adopt the big flywheel of the special-shaped variable-speed motor of outer rotor low-speed big to drive, the balance that the compound balance balance mode of gravity and elastic band can be realized ideal, and moving situation obtains optimum optimization.Near top dead-centre the time, because the inertia effect of flywheel need shift to an earlier date several seconds and shut down, make the up segment distance of sucker rod, up to arriving top dead-centre by the flywheel inertia effect.And the lifting load after shutting down is greater than balancing effect, thereby in the moment that the top dead-centre flywheel inertia effect disappears, lifting load drags tandem-driving bogie and elastic band backward rotation, and motor can be taken advantage of a situation and be approached unloadedly oppositely to start.When motor counter motion during near bottom dead centre, shift to an earlier date several seconds again and shut down, sucker rod arrives bottom dead centre by the flywheel inertia effect, and the balancing effect after the shutdown is again greater than roofbolt load, so motor approaches unloaded steadily commutation, so comes and goes and renews.The oil pumping system that with the jig frequency is per minute 3 times is an example, and a complete stroke cycle is 20 seconds, if shut down for 2 seconds in advance near top dead-centre, shuts down for 2 seconds in advance near bottom dead centre, and then total travel need shut down for 4 seconds.Like this, needed to shut down 4.8 hours promptly pure shutdown economize on electricity 20% in one day.
5. the more conventional asynchronous machine of rare-earth permanent-magnet synchronous motor economize on electricity 8-15%
Because dragging high-efficiency low-consumption intelligent pumping unit, the low-speed big special-shape motor adopt permanent-magnetic outer rotor to drive, need not add field power supply, eliminated excitation loss, efficient is up to more than 95%, maximum detent torque multiple is 3.8 times, compare with common asynchronous moter, its staring torque and overload capacity improve 1-2 doubly, average running current descends more than 50%, natural power factor is brought up to more than 0.95 by about 0.5, and idle power saving rate is reached more than 85%, and meritorious power saving rate reaches more than the 8-15%, and effectively reduce the installed power of motor, improved the utilization rate and the latent capacity of electrical network greatly.
6. self-generating device provides the additional power outside a large amount of system power supplies
Because dragging high-efficiency low-consumption intelligent pumping unit, the low-speed big special-shape motor adopt permanent-magnetic outer rotor to drive, can be as required at the outer rotor wheel rim abrasive rubber wheel place configuration 1-4 platform small power generator that places on the high tower tube, rely on the storage of potential energy and the release triboelectricity of kinetic energy, solve the electricity consumption of illumination, heat radiation, heat-preserving equipment, save the electric power of system power supply greatly.
7. digital intelligent control system has been realized the optimum Match of acting and power consumption
The low-speed big special-shape motor drags high-efficiency low-consumption intelligent pumping unit and adopts the digital intelligent control device to realize randomly regulating, can set up long stroke, the low jig frequency kinetic characteristic of oil pumper according to stratum fluid supply capacity intelligent stepless, oil is the more taken out, oil is few to be taken out less, no oil is not taken out, and makes working system and stratum fluid supply capacity dynamic coordinate, has realized the optimum Match of acting and power consumption, significantly reduce unnecessary idle work, reduced energy consumption to greatest extent.
