Compared with existing oil pumper and actual measurement：
1st, analogue data is 14-type oil pumper, and 4.5 meters of stroke, 2.5 times/min of jig frequency, 1700 meters of well depth, bar is three-level,
16 tons or so, driving power 37kw of weight, running current 60 peace more than（Lifting weight is 21 tons, and descending weight is 16 tons）.
2nd, the downward pulling force in gravitational equilibrium difference oil pumper both ends is the half of upper and lower balanced differences.（21—16）÷2=2.5
Ton × 9.8=24.5KN
3rd, balance weight iron weight：（21-2.5）=18.5 tons.
4th, sucker rod is to upper lifting force（21-18.5）=2.5 tons × 9.8=24.5KN
5th, sucker rod to it is descending when be（18.5-16）=2.5 tons × 9.8=24.5KN
6th, the lifting downward pulling force basis equalization in 21 ton hour both ends only needs the KN of 2.5 ton force × 9.8=24.5.
7th, gravity roller is divided into two 200-Ф of diameter Ф 600, hydraulic oil cylinder driving gravity roller 200 weeks a length of 638mm of Ф,
Quite amplification increases by three times of resistance during reducing Ф 600, and the cylinder circumferences of Ф 600 are 1884mm, and 2.4 turns are needed when lifting 4.5 meters of strokes.
8th, oil cylinder stroke：638 × 2.4=1507.2mm, movable pulley, which is put, is twice distance, and 1/2 equal to 754, mm is oil cylinder row
Journey.
9th, cylinder diameter is Ф 100（Internal diameter）, stroke 754mm, capacity 6.5L, when pressure is 4Mpa, power output
For：（50×50×0.785×4）=7.85 tons, amplification increases three times of resistance（7.85/3）=2.6 tons × 9.8=25.48KN.

=21.66 seconds/once.（60/21.66）=2.77 times/min.
11st, driving power：（25 × 1450r/min × 4MPa/60 minutes）=2.4kw/0.6 operating efficiencies=4kw adapteds
5.5kw or 7.5kw.
When the 12nd, lifting stroke up to 6 meters, oil cylinder stroke is（6000/1884）1/2 turn × the 628 of=3.18 are equal to oil cylinder row
Journey, 998.52mm is only needed to grow.
When lifting 8 meters of stroke, oil cylinder stroke is（8000/1884）1/2 turn × the 628 of=4.2, which are equal to oil cylinder stroke, only to be needed
It is 1318.8mm long.
13rd, compare economize on electricity
1. 14 type beam pumping unit driving power 37kw, lifting weight is 21 ton hours, average running current be 60 peaces with
On.
2. 14 type gravitational equilibriums difference oil pumping motor driving power is 7.5kw, lifting weight is 21 ton hours, and average running current is
8-11 peaces left and right.
3. contrast：60-11=49/60=0.816 is with respect to power saving more than 80%.Efficient technical ability is realized, by Daqing oil field electricity price
0.64 yuan of calculating, year operation calculated power consumption, the electricity charge by 330 days（60×380×24×330）=1805760 degree of electricity × 0.64 yuan=
115568 yuan（11 × 380 × 24 × 330 days）=33105 degree of electricity × 0.64 yuan 21187 yuan, saving the electricity charge in year is（115568-
21187）=94381 yuan.
The beneficial effect that the present invention obtains is：
1st, directly driven using hydraulic jack, thrust output is big, and the speed of travel is low, pumping plant low pressure operation（4-6MPa）, work(
The small low, efficiency high that consumes energy of rate, Ultra-Low Speed operation, for mitigating, the pump cycle is picked up in the abrasion of plunger pump mechanical load and service life obtains
Extend at double.
2nd, amplified again using movable pulley apart from the characteristics of, effectively reduce oil cylinder capacity and oil pump capacity, greatly reduce driving
Power of motor, there is remarkable effect to energy-saving.
3rd, unique counterbalance design, gravitational equilibrium principle make both sides balanced, and mechanical movement is steadily laborsaving, easy to operate, can be fast
Speed is easily accomplished adjustment balanced operation, and balance weight iron can directly land, securely and reliably, without any accessory machinery of adapted.
4th, using converter technique permanent magnet synchronous variable-speed motor, convenient and swift of ginseng need one minute, time saving and energy saving, tool are adjusted
There is an intelligent Remote Control System, wireless remote control start-stop, failure reason analysis digital monitoring function, short message of mobile telephone for alarm prompting,
Human nature service.
5th, body volume is small, simple and reasonable, five square metres or so of floor space, surmounts conventional pumping unit volume, stops
It is more safe and reliable when car system is using hydraulically operated brake convenience, maintaining and tune ginseng operation.
