Definitions

  • Known pumps for pumping of liquefied gas at high pressures comprise different piston and membrane pumps . These pumps operate continuously, often using several pistons or membranes driven by a common motor.
  • Fig. 5 is a diagram illustrating typical values in arbitrarily units of the amount of liquefied gas pumped per time unit as a function of time for the device shown in fig. 1 (solid line) and for the device shown in Fig. 4 (dashed line).
  • the carbon dioxide source is preferably localized, whether it is a bottle or a ring conduit system, above, particularly high above, the pump per se.
  • the hydrostatic pressure which arises in the liquid column, achieved, prevents boiling of the carbon dioxide or at least reduces the amount of carbon dioxide, which boils.
  • Fig. 3c also shows typical values of the amount of plasticized polymer fed per time unit in an arbitrary scale as a function of time for the system for manufacturing of polymer products shown in Fig. 2 (dashed line).
  • communication interface 67 synchronization may thus be performed between feeding of polymer and supply of liquefied carbon dioxide.

Abstract

L"invention se rapporte à un dispositif de pompage de gaz liquéfié comportant un corps de pompe (3) muni d"un alésage cylindrique (5), un piston (15) disposé dans l"alésage du corps de pompe et susceptible de se déplacer entre une position avant et une position arrière; et un organe d"entraînement (19, 21) conçu pour déplacer le piston entre ces positions avant et arrière. Le gaz liquéfié est introduit dans la chambre de la pompe lorsque le piston se déplace de la position avant à la position arrière et il est pompé hors de ladite chambre lorsque le piston se déplace de la position arrière à la position avant. La pompe inclut un organe de régulation (23) conçu pour réguler (i) le mouvement du piston de la position avant à la position arrière de sorte que ce mouvement soit suffisamment lent pour empêcher sensiblement l"ébullition de gaz liquéfié introduit dans la chambre du piston; ainsi que pour réguler (ii) le mouvement du piston de la position arrière à la position avant de sorte que ce mouvement se produise à vitesse variable.
