Title (EN) WELL PUMP SYSTEM
(FR) SYSTEME DE POMPE POUR PUITS
Abstract:
(EN) A well pump system having a motor-driven pump (16) and a pressure tank (26) for delivering water from a source to an utilization point. A sensing device (38, 40) detects a parameter correlated to the rate of flow into and out of the pressure tank (26). The parameter is utilized to regulate flow into the tank so as to establish at least approximate equality between flow into and out of the tank (26).
(FR) Système de pompe pour puits doté d'une pompe à moteur (16) et d'un réservoir sous pression (26) destiné à acheminer l'eau d'une source vers un point d'utilisation. Un dispositif de détection (38, 40) détecte un paramètre corrélatif au débit entrant et sortant du réservoir sous pression (26). On utilise le paramètre afin de réguler le débit entrant dans le réservoir afin d'établir une égalité au moins approximative entre le débit entrant et le débit sortant du réservoir (26).
