Title (EN) FAST ENERGY-SAVING CHAMBER PUMPING
(FR) POMPAGE RAPIDE D'ENCEINTE AVEC ECONOMIE D'ENERGIE
Abstract:
(EN) The invention concerns a device for vacuum pumping comprising at least one main pump (1) and one auxiliary pump (2) connected in series, respectively driven by a first electric motor (1b) and a second electric motor (2b) themselves powered by respective power supplies (1c, 2c) monitored by a processor and a programme recorded in a memory (3b). The programme recorded in the memory (3b) generates a speed variation law (A) of the main pump (1) which decreases regularly, and a speed variation law (B) of the auxiliary pump (2) which increases regularly, so as to reduce energy consumption while maximizing pumping speed.
(FR) Un dispositif de pompage à vide selon l'invention comprend au moins une pompe primaire (1) et une pompe secondaire (2) en série, entraînées respectivement par un premier moteur électrique (1b) et un second moteur électrique (2b) eux-mêmes alimentés par des alimentations respectives (1c, 2c) pilotées par un processeur (3a) et un programme enregistré dans une mémoire (3b). Le programme enregistré dans la mémoire (3b) génère une loi de variation de vitesse (A) de pompe primaire (1) qui décroît régulièrement, et une loi de variation de vitesse (B) de pompe secondaire (2) qui croît régulièrement, afin de réduire la consommation d'énergie tout en maximisant la vitesse de pompage.
