A kind of self balancing intelligent beam pumping unit

Technical field

The utility model relates to the beam pumping unit field, relates in particular to a kind of self balancing intelligent beam pumping unit.

Background technology

The present widely used beam pumping unit in the oil field, structure is seen accompanying drawing 1, reductor (1) crank band dynamic balance weight (2) drives walking beam (4) motion by connecting rod (3), realize the up and down reciprocatingly action of sucker rod (5), there is the shortcoming that counterbalance effect is poor, the clean torque ripple of crank is large in its structure, owing to have negative torque, cause inefficiency and energy consumption large.Need 3 people to cooperate during balancing, also will shut down 1 ~ 2 hour, rock passing with crowbar, labor strength is large, equipment is caused damage and generation personal safety accident easily, and automaticity is low.

Summary of the invention

The purpose of this utility model is to provide a kind of self balancing intelligent beam pumping unit, overcomes existing technical deficiency, improves the balanced structure of oil pumper, realizes the automatic adjustment of beam balance, improves the production efficiency of oil pumper, reduces energy consumption.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of self balancing intelligent beam pumping unit, comprise base, support, walking beam, horse head, reductor, polished rod eye and switch board, afterbody at described walking beam is provided with the autobalance arm, walking beam above the pin joint of support and walking beam is provided with displacement transducer, load transducer be located at polished rod eye and the sucker rod that hangs down along horse head between, displacement transducer all links to each other with switch board with load transducer.

Described autobalance arm comprises fixed arm, swing arm, balancing weight, automatic elevator and leading screw, one end and the swing arm of fixed arm are hinged, one end of swing arm is provided with balancing weight, one end of the other end of swing arm and leading screw is hinged, leading screw is provided with automatic elevator, and automatic elevator links to each other with fixed arm with bearing by cross axial base successively.

Output links to each other the digitlization pumping unit controller with relay with power supply, nixie display, phonetic alarm, wireless communication module, accent jig frequency frequency converter, electricity ginseng acquisition module, sensor, switch input respectively in the described switch board.

Compared with prior art; the beneficial effects of the utility model are: can make walking beam on pumping units be in all the time equilibrium state; motor power consumption is in minimum; realize that the energy-conservation raising of oil pumping is more than 40%; walking beam energy automatic adjusting balance, reduces labor intensity at the downtime of saving artificial balancing; improved productivity ratio, made safety of pumping unit steadily finish oil pumping work.
