Definitions

  • a damper is installed in the form of a support bus, interacting with the front.
  • the connection between the upper bar and the hydraulic cylinder is carried out by means of a clamp with an extension mounted on the cylinder.
  • hydraulic seals are installed in the form of oil seals with channels connected to the body of the fluid.
  • the working fluid from the tank 23 is supplied with the electric motor 12 and the pump 13 through the connection 18 and 15 are supplied to the hydraulic cylinder I.
  • the shut-off valve 24 is supplied to the tank.
  • the top 4 of the hydraulic cylinder is located in the lower “dead” side and in track 7
  • Connection 16 is at this time under constant pressure. Then begins to move
  • shut-off valve 19 closes the regulated shut-off valve 26 with the stop valve.
  • Communication 16 ⁇ - ⁇ as before - 5 - continues to pressure.
  • the cuff is either liquid or non-flowing through channel 22;
  • the inventive invention is intended for the extraction of any liquid products from deep boreholes with barrels at-0.
  • This unit can be used with success for the extraction of liquid products from any depths, since the increased power loads are accelerated.

Abstract

L'ensemble de l'invention comprend un cylindre hydraulique (1) monté à l'aide de la tête (2) au-dessus de la bouche du puits (3), un dispositif d'amortissement se présentant sous la forme d'un manchon (7) à ressort coopérant avec le piston (4) du cylindre hydraulique (1), ainsi qu'une pompe à tiges de pompage de tête de puits. La tige (5) du piston (4) du cylindre hydraulique (1) est reliée cinématiquement aux tiges (9) de la pompe de tête de puits, alors que le joint du cylindre se présente sous la forme d'un bloc d'étanchéité (8) monté dans la tête (2) de manière qu'une de ses parties se trouve en contact avec le cylindre hydraulique (1) et l'autre se trouve en contact avec le puits (3).
