Compare with present technological scheme, the effect of the utility model oil well pump balance load reducer is off-load, energy-conservation, and horse head suspension point stroke is reduced to 1/3rd of oil well pump stroke, solves the problem that pumping unit and oil well pump uplink and downlink out-of-step affect pump efficiency.Utilize the principle of lever balance (balance), on oil pipe, determine a fulcrum, oil well pump (comprising sucker rod, oil pipe) is divided into upper and lower two-part, and make the upper and lower two-part counterweight balance of sucker rod or approach balance, load transfer, to oil pipe, it is zero making pumping unit horsehead polished rod load or close to zero, electric energy is only for overcoming the inertial load work done on sucker rod, oil well pump, thereby play off-load, a large amount of saving power greatly, the machine of increasing substantially is adopted the effect of efficiency.Must be darker under oil well pump, compare off-load when not descending oil well pump balance load reducer, energy-saving effect is more obvious.Movable pulley makes horse head suspension point stroke be reduced to 1/3rd of oil well pump stroke.Can be darker by obtaining under pump, stroke is longer.Be applicable to all oil pumping wells with energy-conservation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model oil well pump balance load reducer.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model oil well pump balance load reducer is by oil pipe 1, static pulley 2, wire rope 3, sucker rod 4, oil well pump 5, horse head suspension point 6, upper and lower rope fixture restricts a little 7 admittedly, on movable pulley, static line device 8 and lower rope fixture 9 form, wherein, static pulley 2 is fixedly connected with oil pipe 1, this fixed connection point is the equinoctial point of oil well pump balance load reducer, wire rope 3 is through lower rope fixture 9, static pulley 2, on movable pulley, static line device 8 is connected in series and is fixed on upper and lower rope fixture and admittedly restricts a little on 7, lower rope fixture 9 is connected with the lower part of sucker rod 4, the lower part of sucker rod 4 is connected with oil well pump 5, sucker rod 4 upper ends are fixedly connected with horse head suspension point 6, oil well pump balance load reducer equinoctial point is by minute upper and lower two-part of upper end horse head suspension point 6 load, horse head suspension point 6 load of upper end equal or be slightly larger than part top sucker rod 4 weight deduct liquid weight that lower part sucker rod 4 weight and oil well pump 5 bear and, the horse head suspension point 6 of upper end with below with oil well pump 5 opposite directions, and under the effect of static line device 8, upper and lower stroke is 1:3 on wire rope 3 and movable pulley, when oil well pump balance load reducer equinoctial point top is up, deep-well oil pump balance load reducer equinoctial point bottom is descending, when oil well pump balance load reducer equinoctial point bottom is descending, oil well pump balance load reducer equinoctial point top is up, and the power of borrowing mutually forms an entity, as the principle of lever balance (balance), does not have upper and lower nonsynchronous problem and off-load.
Utilize the principle of lever balance (balance), on oil pipe 1, determine fixedly static pulley 2 of a fulcrum; Its Placement: be connected in series and be fixed on upper and lower rope fixture with wire rope 3 through static line device 8 on lower rope fixture 9, static pulley 2, movable pulley and admittedly restrict a little on 7, sucker rod 4, oil pipe 1 are divided into upper and lower two-part.Be that the lower part that comprises lower rope fixture 9 connecting with pumping rods 4 is divided in bottom, the lower part of sucker rod 4 is connected with oil well pump 5; Be that the upper part that comprises static line device 8 on movable pulley and insert the sucker rod 4 in static line device 8 on movable pulley is divided on top, the upper end of the upper part of sucker rod 4 is fixed at horse head suspension point 6 places.And make the upper and lower two-part counterweight balance of sucker rod 4 or approach balance, on movable pulley static line device 8 and static pulley 2 and upper and lower rope fixture admittedly restrict a little 7 pass through wire rope 3 load transfer to oil pipe 1 fixed support, the load that makes pumping unit horsehead suspension point 6 is zero or close to zero, electric energy is only for overcoming inertial load work done when up, thereby play off-load, a large amount of saving power greatly, the machine of increasing substantially is adopted the effect of efficiency.The upper and lower two-part of sucker rod 4 by static line device 8 on static pulley 2 and movable pulley and upper and lower rope fixture admittedly restrict a little 7 and wire rope 3 up-downgoings mutually by means of power, form an entity, solved the problem that oil well pump 5 and pumping unit horsehead suspension point 6 uplink and downlink out-of-step affect pump efficiency.Oil well pump 5 times must be darker, compares off-load when not descending oil well pump balance load reducer, energy-saving effect is more obvious.In addition, utilize static line device 8 on movable pulley, make the stroke of horse head suspension point 6 be reduced to 1/3rd of oil well pump 5 strokes, make the movement velocity on horse head suspension point 6 and sucker rod 4 tops slow down 1/3rd, reduced inertial load, make dark pump, long stroke pump sump on ground, use little pumping unit to come true, pumping unit can remove counterweight block, can change low-power machine, can change little retarder, can also be darker by obtaining under pump, stroke is longer.Remarkable benefit.
