Abstract

POMPE CENTRIFUGE A DEBIT CONSTANT. LE ROTOR DE CETTE POMPE COMPORTE DEUX ROUES APPARIEES 24, 26 CONSTITUEES CHACUNE D'UN BANDAGE 24A, 26A SUPPORTANT DES AILETTES 24B, 26B A GEOMETRIE FIXE. CES ROUES SONT ASSUJETTIES A UN ARBRE ROTATIF 12, ET LEUR STRUCTURE PERMET A LA PRESSION QUI S'EXERCE ENTRE ELLES DE LES FAIRE FLECHIR EN LES ECARTANT L'UNE DE L'AUTRE ET EN FAISANT VARIER AINSI LA LARGEUR DU ROTOR. UNE SERVOCOMMANDE 50 REGLE LA PRESSION PRECITEE, DE SORTE QUE LE DEBIT DE LA POMPE EST CONSTANT POUR DES CONTRE-PRESSIONS VARIABLES. APPLICATION AUX POMPES CENTRIFUGES.
