Adachi, Akira; Oba, Sho (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)This case study describes failure incident of a centrifugal compressor, its root cause investigation, and countermeasure implementation. An integrally geared centrifugal air compressor driven by a synchronous motor failed ...

Adachi, Akira; Baba, Yoshitaka (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)Startup transients of both torsional and lateral vibration behaviors of an integrally geared centrifugal compressor driven by a synchronous motor are examined by transient torsional-lateral coupled analyses, and the numerical ...

Adachi, Akira; Murphy, Brian (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Torsional instability during starting of an induction motor has caused excessive torque oscillation and eventual failure of gearbox pinion teeth of a cooling tower fan train. A torsional instability appeared due to a steep ...

Tanaka, Kenji; Adachi, Akira; Takahashi, Naohiko; Fukushima, Yasuo (Texas A&M University. Turbomachinery Laboratories, 2009)Centrifugal compressor train in a refinery experienced high vibration problem due to torsional resonance. Sidebands in the VFD output current based on VFD control loop frequencies were identified as the root cause. In this ...
