A molecular pump maintenance decision management system and method for fusion devices

Abstract

The invention discloses a molecular pump maintenance decision-making management system and method for a fusion device. The system includes a molecular pump state information acquisition and storage module, which is used to obtain the molecular pump operation data and store the real-time state data in a local storage medium. The molecular pump characteristic information extraction module receives the molecular pump operation data, performs data analysis and processing, and extracts the molecular pump characteristic information; the molecular pump life prediction and result output module predicts the life of the molecular pump according to the characteristic information extracted by the molecular pump characteristic information extraction module , to obtain the predicted result; the molecular pump maintenance strategy module is used to formulate the molecular pump maintenance strategy according to the obtained predicted result. The present invention effectively reduces the possibility of actual failure of the molecular pump during the operation of the fusion device through the preventive molecular pump maintenance method, thereby reducing the possibility of secondary accidents in the fusion device caused by the failure of the molecular pump, thereby improving the vacuum in the fusion device. Security of the system and the entire installation.

Description

technical field [0001] The present invention relates to the field of vacuum technology for magnetic confinement fusion devices, in particular to a preventive maintenance method for molecular pumps used in fusion devices, which prompts impending failures of molecular pumps before actual faults occur in molecular pumps, and helps operators of fusion devices to maintain in advance Avoid the occurrence of real faults of the molecular pump, realize the active maintenance of the molecular pump during the operation of the fusion device, and then improve the safety of the fusion device. Background technique [0002] The vacuum pumping system is one of the core subsystems of the fusion device. The quench caused by the failure of the vacuum system will cause the local temperature of the magnet of the fusion device to rise rapidly, thereby destroying the internal structure of the superconductor or even burning the magnet, bringing destruction to the magnet of the device The molecular p...

This method predicts the life and failure of the molecular pump in the fusion device in advance, and replaces and repairs the molecular pump that is about to fail according to the prediction results, thereby effectively reducing the possibility of major accidents occurring in the molecular pump during the operation of the fusion device. In turn, the safety of the vacuum system and the entire device in the device is improved, and the problems of lack of pertinence in the unified maintenance of conventional molecular pumps and maintenance of molecular pumps after accidents are solved. This is of great significance for the automatic operation of future fusion devices and can solve future problems. Difficulties faced by pre-decision-making and pre-maintenance of fusion devices
