Procedury diagnostyczne dla układu wirującego z aktywnym łożyskiem magnetycznym

W pracy przedstawiono koncepcję i wybrane procedury specjalistycznego oprogramowania przy wykorzystaniu zaawansowanych technologii informatycznych dla systemu diagnostycznego dedykowanego układom wirującym maszyn z aktywnym łożyskiem magnetycznym. Jest on wykorzystywany w czasie normalnej eksploatacji maszyny, co pozwala na zwiększenie jej niezawodności.

The paper presents possibilities and current trends in the advanced diagnosis of rotating machine systems with active magnetic suspension. The diagnostic systems designed for this type of unconventional rotating systems have their own specificities, which distinguish them from classical ones. The proposed procedures of the specialized diagnostic software dedicated to rotating systems with an active magnetic bearing allow for automatic execution of measurements, their analysis, and generation of information for an operator about the state of the machine in different phases of the machine work in real-time. It is very important from the viewpoint of the safe operation and the increased reliability of this type of unconventional solutions of rotating machine systems. An important feature of the designed diagnostic system is an open architecture that allows for modifications and extension of the number of the analyzed parameters. The constructed laboratory test stands, where the diagnostic tests were performed, have practical application in industrial machines: to control the vibration of a long flexible shaft of the industrial machinery by an additional magnetic support - safe crossing of the critical frequency, in the exploitation of an active magnetic support as a damper - the drive transmission system for the rear rotor of the helicopter.
