Sealing compressor rotor from toxic gas receiver - using seal forced against rotor blades by magnetic forces when rotor stops
A rotor which compresses a toxic or dangerous gas has a hub rotated by a shaft. An annular sealing joint provides sealing between the hub and a casing when the rotor stops. This joint is carried on a support which moves axially by magnetic action towards the rotor blades. A magnetic circuit comprise...

| description | A rotor which compresses a toxic or dangerous gas has a hub rotated by a shaft. An annular sealing joint provides sealing between the hub and a casing when the rotor stops. This joint is carried on a support which moves axially by magnetic action towards the rotor blades. A magnetic circuit comprises an annular permanent magnet fixed to a moving armature and a fixed armature carried by the rotor. A coil receives a current pulse when sealing is required. This moves the moving armature to displace the annular support to force the seal against the blades. A current pulse in the opposite direction will open the seal.
L'invention concerne un obturateur pour machine tournante devant véhiculer un fluide nocif, susceptible de réaliser, à l'arrêt de la machine, une étanchéité entre l'atmosphère et la partie de la machine baignant dans le fluide nocif. L'invention se caractérise en ce que l'obturateur est mû par un système d'attraction magnétique constitué d'une part, d'un circuit magnétique comportant en série un aimant permanent 12 solidaire d'une armature mobile 13 et une armature fixe 14, et, d'autre part, d'au moins une bobine 12. Ce dispositif obturateur trouve son application sur les compresseurs destinés à la séparation isotopique par diffusion gazeuse. |
