Title (EN) AN IMPROVED PUMP SYSTEM
(FR) SYSTÈME DE POMPE AMÉLIORÉ
Abstract:
(EN) A system and method for pumping a fluid over an at least partially vertical distance is provided. The fluid, such as water, is pumped through a conduit having a substantially vertical portion and gas, such as air, is supplied at or near a bottom region of the vertical portion of the conduit. The addition of the gas to the fluid can advantageously decrease the total dynamic head of the pump in the system, allowing it to operate more efficiently and/or at higher flow rates.
(FR) L'invention porte sur un système et sur un procédé pour pomper un fluide sur une distance au moins partiellement verticale. Le fluide, tel que de l'eau, est pompé à travers une conduite ayant une partie sensiblement verticale et du gaz, tel que de l'air, est distribué au niveau ou à proximité d'une région inférieure de la partie verticale de la conduite. L'ajout de gaz au fluide peut diminuer avantageusement la hauteur manométrique totale de la pompe dans le système, lui permettant de fonctionner de façon plus efficace et/ou à de plus hauts débits.
