Description
Technical field: the utility model relates to a kind of oil field with oil pumping machinery, is meant a kind of energy-saving pumping unit especially.
Background technique: pumping unit is the ground oil production equipment that is used for being not enough to from formation pressure the oil well extraction crude oil of blowing, the high energy consumption of pumping unit, complex structure and maintenance difficulty are the main causes that causes its user cost high always, people have designed energy consumption that much can reduce pumping unit and the new-type energy-saving pumping unit of simplifying its structure for this reason, as the patent No. is 89221243.8, the Chinese utility model patent that name is called " full belt drive pumping unit " is exactly wherein a kind of, this patent has replaced the requirement on machining accuracy height with two-stage or the shift drive mechanism of being made up of drivign belt and belt pulley more than the two-stage, the energy consumption height, easy oil leakage, the gearbox that maintenance cost and manufacture cost are high, thereby reach energy-conservation and purpose that reduce cost, but its drive mechanism of being made up of common v belt and belt pulley exists easily and skids, the operating speed scope is little, single staged transmission ratio is little, the load capacity scope is little, the defective that noise is big, and for the tensioning drivign belt, belt pulley can produce asymmetric axial compression to its back shaft, thereby can accelerate the wearing and tearing of back shaft and axle sleeve; In addition, but the balanced controls of the balancing offset angle on it exist complex structure, it formed component requirement on machining accuracy height, defective that manufacture cost is high.
Summary of the invention: the purpose of this utility model provide a kind of simple in structure, transmission efficiency is high, energy consumption is low, noise is little, easy care, energy-saving pumping unit that manufacturing cost and use cost is low.
The purpose of this utility model is achieved in that a kind of energy-saving pumping unit, comprise walking beam, walking beam support, horse head, sucker rod suspension cable, motor, connecting rod, main deceleration belt pulley, secondary deceleration big belt pulley, secondary deceleration small belt pulley, motor pulley, main drive belt and ancillary drive belt, also be set with radially-arranged crankweb, balance arm on the wherein main deceleration belt pulley and be positioned at the adjustable counterweight of arm of force length on the balance arm, wherein balance arm and crankweb branch are arranged, and balance arm is positioned at the place ahead of crankweb operating movement direction.
The span of the included angle A between the longitudinal axis of balance arm and the longitudinal axis of crankweb is 0 °＜A≤90 °.
Main deceleration belt pulley, secondary deceleration big belt pulley, secondary deceleration small belt pulley, motor pulley are toothed belt wheel, and main drive belt and ancillary drive belt are the profile of tooth drivign belt.
Because the utility model is set with a balance arm that has the adjustable counterweight of arm of force length on it in the place ahead of the moving direction of the crankweb that fixedly installs on the main deceleration belt pulley, so when crankweb moves to top dead center, balance arm and on counterweight not only can its motional inertia work done, but also the moment that can its gravity produces is helped motor and is promoted the sucker rod work done; When crankweb moves to lower dead center, the lifting force that counterweight can utilize the deadweight of sucker rod to produce again moves upward, be work done stored energy next time, it is few that this main deceleration belt pulley has component, simple in structure, the characteristics not high to the component requirement on machining accuracy, so the utility model has realized saving the purpose of the energy equally with simple and practical structure: in addition, because the transmission speed reducer structure that the utility model adopts profile of tooth drivign belt and toothed belt wheel to form is pumped, it is compared with the transmission speed reducer structure that common triangle drivign belt and belt pulley are formed has the transmission efficiency height, non-slip, single staged transmission ratio is big, the operating speed scope is big, the load capacity scope is big, noise is little, the little advantage of tensioning pressure to the back shaft generation.
