Definitions

  • the invention is an oil extraction machine, in particular a linear large stroke pumping unit. Background technique
  • the object of the present invention is to provide a novel linear large-stroke pumping unit, which can overcome the shortcomings existing in the prior art, reduce the inertia impact of the equipment, reduce the invasion of wind and sand, and extend the service life of the equipment.
  • the purpose of the present invention is achieved as follows: It includes a motor and a reducer driven by the motor.
  • the output end of the reducer drives a steel rope transmission device through a set of transmission mechanisms. One end of the steel rope is connected to a weight and the other end is connected to a sucker rod.
  • the motor is fixed at On the machine base, the output end of the reducer drives a planetary gear that meshes with a fixed internal ring gear through a crank.
  • the number of teeth of the internal ring gear is twice that of the planetary gear.
  • One end of the rack is connected to the planetary gear, and the other end is connected to The gears mesh, and the output shaft of the gear drives the wire rope transmission.
  • the above-mentioned transmission mechanism can be installed in a closed casing to avoid the invasion of wind and sand.
  • the advantages of the present invention are: 1.
  • the maximum acceleration is less than 0.6 meters, which can be reduced by 5-7 times compared with the traditional technology, and also reduced by about 40% compared with the best linear pumping unit available.
  • the inertia has dropped significantly.
  • the machine can be completely closed, the lubrication condition of the equipment is improved, the invasion of wind and sand is avoided, the abrasion is greatly reduced, and the service life of the equipment is improved.
  • FIG. 1 is a schematic structural diagram of the present invention. Detailed description

Abstract

L'invention concerne un appareil d'extraction de pétrole sans balancier comprenant un moteur électrique (1) et un réducteur de vitesse (3) commandé par ce moteur (1). La sortie du réducteur de vitesse (3) commande par l'intermédiaire d'un levier (4) une roue planétaire (5) qui est en prise avec une roue intérieure fixe (6). Le nombre de dents de la roue intérieure (6) est deux fois supérieur au nombre de dents de la roue planétaire (5). L'extrémité d'une crémaillère (7) est en prise avec la roue planétaire (5), tandis que l'autre extrémité est en prise avec une autre roue (8) dont l'axe de sortie commande un mécanisme de transmission d'un câble d'acier qui comprend un câble d'acier (11), une extrémité du câble d'acier (11) étant reliée à un poids et l'autre extrémité étant relié à une tige de pompage. L'accélération maximale de cette tige est inférieure à 0,6 m ce qui a pour effet d'en réduire la force d'inertie, améliorant ainsi la lubrification et évitant la formation de poussière.
