Description
Technical field:
The utility model relates to used oil pumper in the oil recovery field, oil field, especially eccentric wheel type oil pumper.
Background technology:
At present, the oil field machinery oil lifting method adopts beam pumping unit, submersible electric pump and screw pump etc. more, and is of a great variety, to adapt to the needs of different productive lives.Now based on beam pumping unit, and beam pumping unit mainly is to adopt quadric chain, and it is poor to adopt the oil pumper of this form to exist exercise performance, and the pay(useful) load rate is low, and the high problem that consumes energy is unfavorable for applying.
The utility model content:
Low in order to solve existing oil pumper pay(useful) load rate, the high problem that consumes energy, the utility model provides a kind of eccentric wheel type oil pumper, and this eccentric wheel type oil pumper has pay(useful) load rate height, and low characteristics consume energy.
The technical solution of the utility model is: this eccentric wheel type oil pumper comprises walking beam, connecting rod that links to each other with rear cross beam and reduction box base, slideway is arranged on the base, slideway is built-in with sliding bottom, be fixed with the reducer that links to each other with motor on the sliding bottom, the output shaft two ends of reducer are connected with pinion, pinion is meshed with eccentric wheel, be connected with pull bar on the output shaft of the outer reducer of gear, another termination of pull bar is connected with the directive wheel that places in the eccentric wheel end face gathering sill, eccentric camshaft is connected with base, the eccentric wheel eccentric shaft is outer and 1-5 bearing pin connecting hole point-blank arranged, and the bearing pin in the connecting hole links to each other with connecting rod.
Output shaft one end of the reducer in the such scheme is connected with gear, and the eccentric wheel eccentric shaft is outer and be connected with bearing pin point-blank, and the bearing pin two ends bearing pin that links to each other with connecting rod reaches the walking beam afterbody up and down and is connected with balancing weight; Be equipped with brake gear on the eccentric shaft in the eccentric wheel; Pull bar is connected on reducer or the sliding bottom.
The utlity model has following beneficial effect: this eccentric wheel type oil pumper is owing to take such scheme, at first by the reducer speed change, and then by pinion and eccentric wheel speed change, make output torque become big at last, so just increase pay(useful) load, reduced energy consumption, saved cost for oil production, helped applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-connecting rod among the figure, 2-reduction box base, 3-slideway, 4-sliding bottom, 5-reducer, 6-eccentric wheel, 7-pinion, 8-pull bar, 9-directive wheel, 10-eccentric shaft, 11-bearing pin, 12-walking beam.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this eccentric wheel type oil pumper comprises walking beam 12, connecting rod 1 that links to each other with rear cross beam and reduction box base 2, slideway 3 is arranged on the base 2, slideway 3 is built-in with sliding bottom 4, be fixed with the reducer 5 that links to each other with motor on the sliding bottom 4, the output shaft two ends of reducer 5 are connected with pinion 7, pinion 7 is meshed with eccentric wheel 6, can adopt internal tooth engagement or external tooth engagement, be connected with pull bar 8 on the output shaft of gear 7 outer reducers 5, pull bar 8 also can be connected on reducer 5 or the sliding bottom 4, pull bar 8 another terminations are connected with the directive wheel 9 that places in the eccentric wheel end face gathering sill, eccentric camshaft 10 is connected with base 2, eccentric wheel eccentric shaft 10 is outer and 1-5 bearing pin connecting hole point-blank arranged, bearing pin 11 one or both ends in the connecting hole link to each other with connecting rod 1, and bearing pin 11 reaches the walking beam afterbody up and down and is connected with balancing weight, are equipped with brake gear on the eccentric shaft 10 in the eccentric wheel.Because motor and reducer 5 are fixed on sliding bottom 4, sliding bottom 4 can horizontally slip in slideway 3, the pinion 7 that connects when driven by motor reducer 5 output shaft two ends rotates, effect lower slider base 4 eccentric wheel 6 motions thereupon at pull bar 8, so just remain the engagement of pinion 7 and eccentric wheel 6, making pinion 7 drive eccentric wheel 6 rotates, because of the axle center of eccentric wheel 6 is eccentric, eccentric wheel 6 movement locus change, 1 swing of eccentric wheel 6 pulling connecting rods, circular motion is converted into rectilinear motion up and down, walking beam 12 is pumped, reach the lifting purpose.Because of slowing down with eccentric wheel 6 through reducer 5 and pinion 7, output torque is increased, so just improved pay(useful) load, cut down the consumption of energy, saved cost for oil production.
