Abstract
The invention relates to a special-shaped walking beam stroke-lengthening composite balanced oil pumping unit. The oil pumping unit mainly comprises a base (I), a braking system (II), an electromotor device (III), a speed reducer (IV), two cranks (5), main balancing weights (5'), a connecting rod (6), a cross beam (7), a rear special-shaped walking bream, a front special-shaped walking beam, a cross arm beam (10), auxiliary balancing weights (16) and a support (17), wherein the two cranks (5) are arranged at both ends of an output shaft (4) of the speed reducer (IV); the main balancing weights (5') are arranged on the two cranks (5); and the cross arm beam (10) is arranged on the front special-shaped walking beam. The power of the electromotor device (III) leads a long arm (12) of the front special-shaped walking beam to swing up and down regularly by a belt pulley (1.2), an input shaft (3) of the speed reducer (IV) and the cranks (5) at both ends of the output shaft (4) of the speed reducer (IV), the connecting rod (6), the cross arm (7) and the rear special-shaped walking bream, and therefore a suspension point load (15) is driven to do regularly up and down alternative reciprocating vertical rectilinear movement by a steel wire rope group (14) fixed at a mule head (13) at the front end of the long arm of the front special-shaped walking beam so as to achieve the purpose of sucking crude oil.
Description
Normal conventional beam pumping unit reliability height, simple in structure, easy to maintenance, but wanting to realize long stroke, low jig frequency, its volume and weight will sharply increase, and gives transportation, installs, uses and bring a lot of difficulties.In actual use, the disconnected accident probability height that takes off sucker rod is salvaged sucker rod often, causes the maintenance cost height, and oil production reduces.
Two horse head oil pumping functions realize that starting torque is bigger during commutation than long stroke, but its counterbalance effect is undesirable.
Be entirely the beam pumping unit of the direct balance of walking beam, counterbalance effect is more satisfactory.But want to realize long stroke, just exist and the same shortcoming of normal conventional beam pumping unit, and adjustment balance and length of stroke are very inconvenient.
Wide belt oil pumping machine is the pylon vertical type of sealing, can realize long stroke, be again direct balance, good balance effect is installed but its driving chain is that long distance is vertical, balance weight is installed in the pylon of vertical sealing, in case break down, can not keep in repair necessary overall pulling down at the scene, be transported to the maintenance of professional manufactory, maintenance is extremely inconvenient.The used wide belt of this type again must be from external import, and its price is very high, and the complete machine price is expensive especially, more than 40 ton of complete machine weight, the problems referred to above make its can only indivedual oil fields among a small circle in use, each oil field large scale application at home.
The China's oil industry is that the production capacity rich and influential family is again the big power consumer, how to cut down the consumption of energy, saves cost, obtains greatest benefit, and making the oil field become especially big energy-saving enterprise is extremely urgent significant problem.And the consumption costs of oil pumper integral body (comprising consumption, maintenance cost, accessory replacing of electric energy etc.) is first sport in the total energy consumption of oil field, and the solution of this problem is concerning petroleum industry upstream industry overall efficiency.
Several elephants of China land have entered middle and advanced stage in succession at present, and water content constantly raises.
Develop a kind of suitable field extreme environment, uniterrupted duty, reliability height, simple in structure, installation and maintenance convenience, low cost of manufacture in sum, stroke is long, jig frequency is low, energy-conservation oil pumper of new generation is a major issue of benefiting the nation and the people.
The special-shaped walking beam of the present invention increases the journey compound balanced pumping unit, the variety of issue that exists at above-mentioned several oil pumpers and the present situation in oil field and design machine.
Oil pumper of the present invention mainly is made up of two cranks (5) on output shaft (4) two ends of base (I), brake system (II), electronic device (III), reducer (IV), reducer (IV), the main balance weight (5 ') on the crank (5), connecting rod (6), crossbeam (7), the special-shaped walking beam in back, preceding special-shaped walking beam, auxiliary balance heavy (16), support (17).The special-shaped walking beam in back is made up of long-armed (8), the galianconism (9) of the special-shaped walking beam in back.Preceding special-shaped walking beam is made up of cross-arm beam (10), galianconism (11), long-armed (12) on the special-shaped walking beam galianconism (11) before being fixed on.The special-shaped walking beam in back, preceding special-shaped walking beam are installed in the top of support (17).Two connecting rods (6) are connected with crossbeam (7).The part of roller is housed on the cross-arm beam (10) before being fixed on the special-shaped walking beam galianconism (11), is pressed on the special-shaped walking beam galianconism in back (9).Auxiliary balance heavy (16) is fixed on the rearward end of the special-shaped walking beam in back long-armed (8).
The amplitude of oscillation of special-shaped walking beam long-armed (12) increased before the special-shaped walking beam in back made by cross-arm beam (10), thereby increased the length of stroke of oil pumper.
Both sides have a support bar (18) and (19) respectively before and after support (17) top, and support bar (18) is connected with long-armed (8) of the special-shaped walking beam in back, and long-armed (12) of support bar (19) and preceding special-shaped walking beam are connected.
