Abstract (en)
[origin: JP2022075494A] To provide a method for operating a vacuum pump, configured such that abrasion for a safety bearing is as small as possible.SOLUTION: The setting of an operation set value for a vacuum pump is prepared, and the setting of the operation set value includes at least one operation state of the vacuum pump, which should be achieved during a trouble event. Furthermore, when the trouble event is detected, and during the trouble event, a rotor is separated from a space region set to a stator, and abrasion occurs to a safety bearing. on the basis of the detected trouble event, an increased amount of abrasion for a safety bearing 215 is estimated, and the increased amount of abrasion is added to a variable for the total abrasion of the safety bearing 215. on the basis of the setting of the operation set value for the vacuum pump 111, and on the basis of the total abrasion of the safety bearing 215, it is finally determined whether means for stabilizing the rotor 149 is performed.SELECTED DRAWING: Figure 3
