Abstract
An energy-saving balance walking beam pumping unit comprises a platform, a base, a support, a walking beam, a rotation shaft of the walking beam, a horsehead, a counterweight box, an electric control cabinet, a driving wheel, a motor, a guiding wheel and a sucker rod. The energy-saving balance walking beam pumping unit is characterized in that two supporting arms with the rotation shaft of the walking beam serving as a datum are symmetrically connected with a loading box below the walking beam to form an energy-saving device, the upper ends of the two supporting arms are connected to the lower surface of the walking beam, the lower ends of the two supporting arms are respectively connected to the two sides of the loading box, the total weight of the two supporting arms and the loading box is W, the rotation radius of the horsehead is R, the distance of the center of gravity of the loading box and the center of the rotation shaft of the walking beam is H, the pendulum angle of the walking beam is phi, and the weight of the oil column in the oil drawing pipe is t oil. When W is equal to (R/2Hsin phi) t oil, the torques of the two sides of the walking beam near to reversing point of every time of the pumping unit keep balance, so that the whole machine can start or brake under no load condition, thereby the energy is greatly saved. The energy-saving balance walking beam pumping unit has the advantages of being simple and reliable in structure, easy to adjust the supporting arms and the weight of the loading box and remarkable in energy-saving effect.
Description
Technical field
The present invention relates to extracting device of oil, relate generally to energy-saving balance type beam-pumping unit.
Background technology
At present, the balance type beam-pumping unit running and comparing of patent No. ZL200720127503.0 is steady, and energy-saving effect is better, but its motor when frequently commutating starting current and stalling current larger, thereby the whole energy-saving effect of impact.The load that sucker rod rises when descending concerning beam pumping unit is fully different, and their difference is also larger, how to realize in this case larger energy-conservation be a problem anxious to be resolved.
Summary of the invention
The purpose of this invention is to provide a kind of energy-saving balance type beam-pumping unit, the excessive and large problem that consumes energy of the electric current that solves the electric motor starting of oil pumper or braking.
For achieving the above object, the invention provides a kind of energy-saving balance type beam-pumping unit, comprise platform, base, support, walking beam, walking beam revolution axis, horse head, counterweight, electrical control cubicles, driving wheel, motor, directive wheel, sucker rod, it is characterized in that: connect by two support arms and the energy saver that articles holding box consists of as benchmark is symmetrical take walking beam revolution axis below the walking beam, the upper end of two support arms is connected to below the walking beam, the lower end of two support arms is connected to the both sides of articles holding box, the gross weight W of two support arms and articles holding box, the radius of gyration of horse head is R, distance between the center of the center of gravity of articles holding box and walking beam revolution axis is H, the pendulum angle of walking beam is φ, and the weight of oil column is t in the oil pick-up tube
Oil, when
The time, the moment of torsion on walking beam both sides keeps balance near the each reversal point of energy-saving balance type beam-pumping unit, so the starting of complete machine or braking all under without the power consumption state, carry out, therefore very energy-conservation.
Advantage of the present invention is: simple and reliable for structure, the weight of adjusting support arm and articles holding box is easy, and energy-saving effect is remarkable.

The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the present invention includes base 1, platform 15, support 12, walking beam 14, walking beam revolution axis 13, horse head 10, electrical control cubicles 21, driving wheel 2, motor 4, directive wheel 6, sucker rod 7, drive rope strainer 11, strainer 16, drive rope 17, counterweight 18, counterweight leading truck 19, brake 20, driving wheel 2, belt 3, drive rope tension device 5, connect by two support arms 9 and the energy saver that articles holding box 8 consists of as benchmark is symmetrical take walking beam revolution axis 13 below the walking beam, the upper end of two support arms is connected to below the walking beam, the lower end of two support arms is connected to the both sides of articles holding box, the gross weight of two support arms and articles holding box is W, distance between the center of the center of gravity of articles holding box and walking beam revolution axis is H, the pendulum angle of walking beam is ± φ that the weight of oil column is t in the oil pick-up tube
Oil, the weight of sucker rod is t
Bar, the driving force that drives on the rope is t
Drive, the radius of gyration of horse head is R, the weight of counterweight of oil pumping unit is t

Walking beam both sides equalising torque was closed and is when sucker rod started in the limit inferior position so: the clockwise moment that anticlockwise moment=sucker rod that the anticlockwise moment that the anticlockwise moment that counterweight produces+energy saver produces+the driving rope produces and oil column produce, i.e. (t

When satisfying above-mentioned condition, motor starts under no-load condition or brakes, and starting or the braking of same oil pumper when the limes superiors position satisfied above-mentioned condition and also can be realized starting or the braking of motor under non-loaded.Therefrom the distance H at the center of the weight W of visible energy-saving adjusting device and energy saver centroidal distance walking beam revolution axis and the pendulum angle ± φ of walking beam just can realize starting or the braking of motor under no-load condition.Concerning motor, bringing onto load starting or braking, not bringing onto load starting or braking then its current sinking differ greatly.The electric current that consumes of bringing onto load time starting or braking is not minimum, and is therefore at this moment the most energy-conservation.
