Title
(EN) PORTABLE VACUUM PUMP ASSEMBLY AND MASS SPECTROMETER
(FR) ENSEMBLE POMPE À VIDE PORTABLE ET SPECTROMÈTRE DE MASSE
Abstract
(EN)
A portable vacuum pump assembly and mass spectrometer are disclosed The portable vacuum pump assembly comprises: a vacuum pump; an internal power supply; and power control circuitry for providing an uninterrupted power supply to the vacuum pump. The internal power supply comprises a removable primary power supply and a further power supply; and the power control circuitry is configured to maintain a continuous power supply to the vacuum pump such that a motor of the vacuum pump is continuously driven, the power control circuitry being configured to route power to the vacuum pump from the internal power supply by initially routing power from the primary power supply and on determining an imminent interruption in a supply of power from the primary power supply, switching to route power from the further power supply to the vacuum pump.

L'invention concerne un ensemble pompe à vide portable et un spectromètre de masse, lequel ensemble pompe à vide portable comprend : une pompe à vide ; une alimentation électrique interne ; et des circuits de commande de puissance pour fournir une alimentation électrique ininterrompue à la pompe à vide. L'alimentation électrique interne comprend une alimentation électrique primaire amovible et une autre alimentation électrique ; et les circuits de commande de puissance sont configurés pour maintenir une alimentation électrique continue vers la pompe à vide, de telle sorte qu'un moteur de la pompe à vide est entraîné en continu, les circuits de commande de puissance étant configurés pour acheminer une puissance à la pompe à vide à partir de l'alimentation électrique interne par acheminement initial de puissance à partir de l'alimentation électrique primaire, et, lors de la détermination d'une interruption imminente dans une alimentation de puissance de l'alimentation électrique primaire, à effectuer une commutation pour acheminer la puissance à partir de l'autre alimentation électrique à la pompe à vide.
