CA 2725168

A seal monitoring and control system for a gas lubricated non-contacting seal includes various sensors providing signals to a programmable logic control system. The control system is disposed to determine a presence of an anomalous operating condition of the seal, for example, based on phase, relative position of rotor to stator or other signals in combination provided by the various sensors to provide an output signal, which in one embodiment performs at least one mitigating process to correct the anomalous operating condition by adjusting at least one operating parameter of the seal.

Un système de surveillance et de contrôle de joint pour un joint sans contact lubrifié au gaz comprend différents capteurs fournissant des signaux à un système de contrôle logique programmable. Le système de contrôle est conçu pour déterminer la présence d'une condition de fonctionnement anormale du joint, par exemple, à partir d'une phase, d'une position relative du rotor par rapport au stator et d'autres signaux combinés fournis par les différents capteurs pour fournir un signal de sortie, lequel, dans un mode de réalisation, réalise un ou plusieurs procédés datténuation visant à corriger la condition de fonctionnement anormale en réglant au moins un paramètre de fonctionnement du joint.
