✦ Synopsis

Seal failure in critical applications can have severe implications, which is why it is important to detect problems and correct them before they develop further. This article looks at monitoring and controlling the dynamic behaviour of a noncontacting mechanical face seal, having a flexibly-mounted rotor in a seal test rig. In particular, it focuses on detecting and controlling the contact between the rotor and stator that may cause severe face wear and imminent seal failure. Noncontacting mechanical face seals are used extensively in centrifugal pumps, compressors, powered vessels and other high-performance rotating machinery. Unpredictable seal failure in critical applications may have severe implications.
