Abstract

L'invention concerne la fabrication de pompes vibratoires à entraînement électromagnétique. Le résultat désiré est obtenu par l'utilisation de la stabilisation à ferrorésonance de la tension sur les bobines de l'entraînement électromagnétique et par la variation de la tension dans ces bobines en fonction du débit. A cet effet, le circuit sériel de la pompe vibratoire et du condensateur est transformé en un circuit oscillant paramétrique. Les bobines (8) sont bobinées de manière à saturer le noyau, et la régulation de tension s'effectue par la modification de la résistance par induction de l'entraînement électromagnétique en cas de variation de débit. A cet effet, les suspensions d'amortissement (11) et élastique (12) sont réalisées de manière à prévoir l'entrefer moyen dans le noyau de 30-40% en cas de débit maximal. La pompe vibratoire pour la mise en oeuvre de ce procédé comprend un boîtier séparé (3) accueillant des condensateurs (4 et 5) branchés en série et en parallèle avec les bobines (8). Les bobines (8) sont réalisées de manière à saturer le noyau (6), et la superficie de la suspension (12) possède la rigidité de la suspension (11) selon le rapport indiqué.
