Advantage of the present utility model and good effect are:
Chain-driven: (1) outstanding advantage is simple and reliable for structure, and stable drive is reliable, and adjustable center distance realizes big stroke easily concerning pumping unit.(2) chain cycle rotation between two sprocket wheels does not contact with any object, and frictional force is zero; (3) be a plurality of tooth interlocks rotations between sprocket wheel and the chain, the roller of a plurality of like this sprocket tooth and a plurality of chains acts on stressed simultaneously, every some active force is all little, has improved the working life of sprocket wheel, chain so greatly.(4) sprocket wheel and chain strip adoption NBS product, very convenient, the low price of market purchasing, simple in structure, be convenient to make, assemble, maintain.
The chain type energy-saving pumping unit is compared with the technical performance of walking beam machine, and the chain type energy-saving pumping unit is than walking beam machine:
1. economize on electricity 50%;
2. the retarder moment of torsion is little five times;
3. the homotype machine oil amount of drawing doubles;
4. 8 meters pumping units are saved about one times of steel, and 5 meters, 3 meters machines are saved 30% steel;
5. about the rated load utilization ratio doubles;
6. realize long stroke or ultra-long-stroke (more than 8 meters) load (more than 16 types) oil pumping easily;

8. the main movement parts life-span is long, roller chain safety coefficient 50-61, and roller chain is at the chain cover of sealing
In and have suitable lubricating life can reach 15 years.
Set forth its advantage and good effect from this novel art designs and principle:
1. design unique novel commutator:
(1) duplex chain has enough tension loads, and a joint outer plate is replaced by special special carrier bar, and the double end bent axle is fixed on the special carrier bar, and bent axle pumps along with the circulation of chain, drives commutator straight line motion up and down;
(2) design special commutator, for
Type.Two openings are avoided two active and passive sprocket shafts;
(3) spindle nose of two of commutator bent axles is equipped with four rollers, roller in place, two dead points specialized designs up and down roller buting iron (seeing Fig. 2, Fig. 3).
Advantage is: the straight line motion up and down reciprocatingly in the chain both sides of commutator symmetry, and the power that acts on commutator is symmetrical, does not have lateral stress, does not have shock and vibration, does not produce moment of flexure; Have good kinetic characteristic, dynamic property.
2. balance mode
The balancer weight of design is firm in commutator two ends and neutral position with bolt.Make pumping unit have good equilibrium response and roadability.The total pulling force that the chain of pumping unit bears is the difference of polished rod load and balancer weight, and is simple to operation.Improved system effectiveness, conservation of power consumption.
Principle analysis:
Chain-driven is adopted in the design of chain type energy-saving pumping unit: simple in structure, standard universal spare is many, stroke is easy to adjust, is convenient to realize big stroke.
1. stress rational in infrastructure is good.The commutator design is also designed
Type.All power all is symmetrically distributed in the chain both sides, does not have lateral bending stress, not vibration.
2. suspending point loading and stroke are irrelevant:
The equation of retarder Maximum Torque and suspending point loading is:
Mmax＝1/2(Pmax-Pmin)R
Mmax---retarder Maximum Torque
Pmax---maximum polished rod load
Pmin---minimum polished rod load
R---sprocket wheel reference radius
Find out that from equation Mmax and Smax (maximum stroke) are irrelevant, R changes for a short time generally between 0.25-0.3 simultaneously, and the retarder moment of torsion is little, and load utilization ratio and stroke have nothing to do, so utilization ratio can reach 100%.
Operate at full capacity so the chain type energy-saving pumping unit adapts to, moment of torsion and motor can overburdening.The designing and calculating parameter of chain type energy-saving pumping unit is by maximum load, maximum stroke, the design of maximum jig frequency.
3. the contained load of commutator is made uniform motion in a straight line 90% in upstroke, only does the simple harmonic motion of standard about last lower dead centre during commutation.
Motion equation is: Y=Vot
0+ Rsin ω t
1
The shift reciprocately of Y-commutator
V
0The speed of-constant speed straightway
t
0The working time of-constant speed straightway
R-sprocket wheel reference radius

1-time of standard pitch circle operation up and down
ω-angular velocity
In constant speed straightway acceleration a=0, noninertia power.The active force pulsating movement free, owing to do the simple harmonic motion of standard, commutation does not steadily have impact, because two chain sense of rotation are opposite, is symmetrical in polished rod again when commutating about last lower dead centre, so no lateral force and vibration take place.
4. balance mode is the counterweight balance, and the degree of balance can reach more than 97%, and balancing run is easy.
