Survey and contrast with existing oil pumper：
1st, existing oil pumper is applied after number, is also constantly groped to seek innovation transformation, is striven energy-saving effect, but all not from knot
Escape and free in structure principle, innovation investment is very big, but energy-saving effect is all preferable not to the utmost, also just in 20-30% or so, so far
Operate in highly energy-consuming state.One common 6 type oil pumper gross mass is 12 tons or so, and driving power carries between 30-40kw
Lift is 5 ton hours, operation average current left 35-40 peace left and right, and motor is from starting 750r/min-118r/min belt transmissions
Lose work(10% or so.Reductor decelerates to 4-6rr/min from 118r/min, and speed compares up to 20:1, directly lost although increasing moment of torsion
Between work(30-40%, in the laborious lever plus the resistance of difference mill and amplification stroke（2.5 meters divided by 1.92 meters=1.3 times of walking beam）, lose again
Fall 30%, 70-80% work(has just been lost during mechanical transfer, actual motion just applies 20-30%, and exploratory development is looked for
It is exactly to save to return the work(lost, and research and innovation, which changes structure, can give that lose can be exactly to increase the benefit for change.
2nd, drum-type-balanced differences oil pumper, realizes the change of essence from structural principle, and emphasis considers existing oil pumping
Machine seriously loses the shortcomings that work(etc. causes highly energy-consuming, abundant the characteristics of applying hydraulic-driven, high torque slow speed is obtained maximum hair
Wave, drum-type-balanced differences Pumping Unit design is simple, and mechanical transfer link is few, and frictional resistance is small, and performance is high, operation
Convenient, consume energy low, efficiency high, and maximum stroke is up to more than 8 meters, to existing 2.5 meters of stroke, for the Common Parameters that jig frequency is 4 times,
Jig frequency only needs 1.3 cans to meet to require, the mechanical load abrasion and service life for mitigating rod tube pump are extended at double,
Operation caused by reduction therefore, prediction pump detection period is also said to be extended at double, oil field operation cost is greatly reduced, with drop
Secondary increasing journey, the characteristics of efficient electricity-saving.
3rd, template test scene：
（1）, a 14 type oil pumper data：6 meters of stroke, jig frequency 2.5 times/min, power of motor 37kw.Well depth 1700
Rice, sucker rod are three-level bar, and about 16 tons or so of weight, operation average current is more than 50 peaces.Upper 21 tons of lifting weight, it is descending heavy
Measure as 16 tons.
（2）, drum type hydraulic pumping unit both ends counterweight balanced differences half be the downward pulling force in both ends.Upper lifting force is 21
Ton, descending 16 tons of power, difference is 5 tons of 2=2.5 tons of ÷.
（3）, balance weight iron weight：（21-2.5）=18.5 tons
（4）, sucker rod be to upper lifting force（21-18.5）=2.5 tons
（5）, sucker rod to it is descending when be（18.5-16）=2.5 tons
（6）, lifting the downward pulling force basis equalization in 21 ton hour both ends, only need 2.5 tons, fluid power drum oil pump is in any condition
Under, both ends are all balanced, no matter drive multiple, are all the half weight of balanced differences, are the downward pulling force in both ends.
（7）, drive sprocket and roller be in same axle, drive sprocket a diameter of 318mm, Zhou Changwei 1000mm.Roller is straight
Footpath is 955mm, and Zhou Changwei 3000mm, reducing, which quite amplifies, increases by three times of resistance.When stroke is 6 meters, roller turns for amount.
（8）, oil cylinder stroke：Drive sprocket-turn-week a length of 1000, in the presence of movable pulley puts distance again, a phase inversion is worked as
In the distance that amount turns, oil cylinder stroke 1000mm.
（9）, cylinder diameter is equivalent to 86mnm, stroke 1000mm, capacity 6.38L, pressure 6Mp2When, output
Thrust is（43×43×0.785×6Mpa）=8.7 tons, amplification increases three times of resistance（8.7÷3）2.9 tons of thrust output.
（10）, jig frequency：Oil pump MCr14-25 types, during 1450r/min, discharge capacity per second is -0.6L.（6.38L÷0.6L=
10.6 seconds × 2=21.2 seconds are once reciprocal）, 60 21.2=2.83 times/min of ÷.
（11）, motor power：（25 × 1450r/min × 6Mpa/60 minutes）0.6 efficiency of=3.6kw ÷=6kw.
（12）, drum-type-balanced differences oil pumper, average running current is 8 peace left and right.
（13）, economize on electricity contrast：（50=42 ÷ 50 of amp- 8 peace）=0.84 relative economize on electricity is more than 80%.
By Daqing oil field electricity price：0.64 yuan of calculating, year operation calculated power consumption and the electricity charge by 330 days.
Beam-pumping unit：50 × 380 × 24 × 330 days=150480kw/h × 0.64=96307 yuan of peace are the year electricity charge.
Drum-type balanced differences oil pumper：8 × 380 × 24 × 330 days=24067kw/h × 0.64=15408 yuan of peace are year electricity
Take.
Update year after next province's electricity charge（96307-15408）=80899 yuan are to save the electricity charge in year.
The beneficial effect that the present invention obtains is：
1st, it is big using hydraulic jack direct drive thrust output, Transformation Application, it instead of the bulky reductor of highly energy-consuming.Liquid
Small low, the efficiency high that consumes energy of press pump station power, low speed operation, mitigates mechanical load abrasion to plunger pump and picks up pump cycle and service life
Extended at double.
2nd, using roller and movable pulley double combinations put again apart from the characteristics of, one meter of oil cylinder row, stroke is put up to six meters
Big effect.Oil cylinder capacity and oil pump capacity are effectively reduced, greatly reduces driving power, it is energy-saving to amplification stroke to play significantly
Effect.
3rd, balanced design Balance principle, both ends are balanced, and what the operation of drum-type balanced differences oil pumper only drove is balance
The power of poor half makes mechanical movement steady, more laborsaving, adjusts ginseng is convenient to be easily rapidly completed adjustment balanced operation, balance weight iron
Can directly it land, securely and reliably, without any hoisting aids machinery equipment of adapted.
4th, using converter technique permanent magnet synchronous variable-speed motor, adjust ginseng convenient and swift, only need one minute, it is time saving and energy saving,
Intelligent Remote Control System, wireless remote control start-stop, failure reason analysis digital monitoring function, short message of mobile telephone for alarm prompting, people
Property service.
5th, body volume is small, simple and reasonable, five square metres or so of floor space, surmounts conventional pumping unit volume, stops
Car system uses hydraulic braking, easy to operate, more safe and reliable when making maintenance, maintenance and adjusting ginseng operation.
