All balance long stroke oil pump provided by the invention is characterized in that comprising hinge (1), frame (2), polished rod eye (3), pull rope (4), it wheel assembly (5), reducer (6), motor (7), upper mounting plate (8), directive wheel (9), ladder (10), counterweight pull rope (11), suspension ring (12), counterweight suspension rod (13), counterweight is adjusted piece (14), main balance weight body (15), adjust leading screw (16), adjust screw (17), counterweight cushion pad (18), polished rod (19), switch board (20), pull rope fixator (21), bearing support (22), it wheel bearing (23), it wheel shaft (24), reducer output, power shaft shaft coupling (25), (26), decelostat (27); Described reducer (6) is a tooth difference speed reducer, links to each other with motor (7) by input shaft coupling (26), decelostat (27), and reducer (6) output shaft links to each other with a day wheel shaft (24) by shaft coupling (25); Described balance weight body (15) is made up of main balance weight body and adjustment balancing weight (14), and wherein main balance weight body is formed inside by bulge heavy metal powder or little block are housed, and adjustment balancing weight intersection is superimposed upon the square sheet piece that has breach on the main balance weight body; Fixator (21) two ends of the clamping plate type of described pull rope system by being located at head sheave inside are connected with suspension ring with polished rod eye respectively, and polished rod eye links to each other with balance weight body with polished rod respectively with suspension ring; Regulate screw (17) rotation pulling leading screw (16) and drive 5 °～8 ° of the whole hypsokinesis of frame (2); The slow startup that the programmable controller controls motor produced polished rod top dead centre, lower dead center 1～3 second is quickened then.
In all balance long stroke oil pump provided by the invention, be provided with tooth difference speed reducer, moment of torsion is big, reliability is high, efficient is high, makes oil pumper have shock resistance, overload-resistant ability improves greatly, thereby has improved the application life of complete machine.Described balance weight body is made up of main balance weight body and adjustment balancing weight, and wherein main balance weight body is made up of the metal circular container, and heavy metal powder or little block are equipped with in inside, and the adjustment balancing weight is superimposed upon the round sheet piece that has breach on the main balance weight body; Can accomplish that thus volume is little, can accurately adjust counterweight arbitrarily.
The slow startup that the programmable controller controls motor produced polished rod top dead centre, lower dead center 1～3 second is quickened then, reduces the shock loading that commutates and start and cause suddenly, thus the life-span of having improved transmission system greatly.
This oil pumper has simple in structure, easy, easy to maintenance, reliable, the advantages such as pumping efficiency is high, environmental protection and energy saving of adjustment in sum.Compare with conventional beam-pumping unit and can economize on electricity 30～50%, pump efficiency improves more than 20%.This all balance long stroke oil pump can be widely used in various types of oil fields.

The specific embodiment
The utility model is described in further detail in conjunction with the accompanying drawings with specific embodiments in the present invention, but protection scope of the present invention is not limited to following specific embodiments.
All balance long stroke oil pump provided by the invention comprises: go up at frame (2) top platform (8) motor (7), decelostat (27), reducer (6), reducer input and output shaft connection (26), (25), day wheel assembly (5) (bearing support 22, bearing 23, day wheel shaft 24) are installed.During work, upstroke, motor (7) just changes (Fig. 1 clockwise direction), by decelostat (27), reducer input shaft shaft coupling (26), reducer (6), reducer output shaft coupling (25), day wheel shaft (24), head sheave (5) clockwise rotates, thereby pull rope (4) drives polished rod (19) lifting by polished rod eye (3).Down stroke, motor (7) counter-rotating (Fig. 1 counterclockwise), rotate counterclockwise by decelostat (27), reducer input shaft shaft coupling (26), reducer (6), reducer output shaft coupling (25), day wheel shaft (24), head sheave (5), thereby pull rope (4) drives polished rod (19) decline by polished rod eye (3).Counterweight pull rope (11) connects balance weight body (15) by suspension ring (12), pull rope (4) is connected with suspension ring (12) with polished rod eye (3) respectively by fixator (21) two ends that are located at the inner clamping plate type of head sheave (5) with counterweight pull rope (11) pull rope system, polished rod eye links to each other with balance weight body with polished rod respectively with suspension ring, during head sheave (5) rotation, drive pull rope (4) and move back and forth synchronously with counterweight pull rope (11).Polished rod load and balance weight body (15) counterweight balance, motor (7) rotating commutation running makes sucker rod and deep well pump do straight reciprocating motion, finishes the crude oil swabbing operation.
When the oil pumper counterweight need be made balance adjustment, changeable counterweight regulating block (14) got final product.When needing fine setting, can increase and decrease the heavy metal particles or the powder of balance weight body (15).
