Abstract

La présente invention concerne une pompe à rotor du type en spirale, essentiellement composée d'un corps (1) de pompe, d'un palier de butée, d'un rotor d'entraînement (2) et d'un rotor entraîné (3). Le rotor d'entraînement (2) et le rotor entraîné (3) sont agencés dans le corps (1) de pompe et entrent extérieurement en prise l'un avec l'autre, le palier est agencé au niveau de la jonction d'un arbre et du corps (1) de pompe, les surfaces latérales du rotor d'entraînement (2) et du rotor entraîné (3) et les surfaces de pointe de pale des rotors sont relativement étanches, une ouverture d'aspiration (4) et une ouverture de sortie (5) sont agencées sur le corps (1) de pompe, et l'ouverture d'aspiration (4) est séparée de l'ouverture de sortie (5) par le rotor d'entraînement (2) et le rotor entraîné (3). Le rotor d'entraînement (2) et le rotor entraîné (3) sont des rotors du type en spirale. Le rotor d'entraînement (2) est pourvu d'une extrémité A et d'une extrémité B qui sont symétriquement conçues, et le rotor entraîné (3) est pourvu d'une extrémité B et d'une extrémité A. L'extrémité A et l'extrémité B sont toutes les deux du type en spirale. Grâce à la rotation synchrone d'une paire de rotors en chevrons dans des directions opposées, et à la conception symétrique des extrémités A et des extrémités B des rotors, les forces axiales générées peuvent mutuellement se compenser, et la force axiale générée pendant le fonctionnement de la pompe à rotor peut être sensiblement supprimée, de sorte que la charge du palier soit réduite, la durée de vie du palier soit prolongée et qu'un fonctionnement sûr et fiable de la pompe à rotor soit réalisé.
