Overcoming Failure of Synchronous Motor Driven Compressor Train by Application of Controlled Slip Clutch
Abstract
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 during its initial startup in a newly constructed petrochemical plant. Failure mechanism was identified as torsional resonance during synchronous motor’s startup with stronger torque amplification than the design intention. As a quick yet very effective solution to this problem, a clutch with controlled slip mechanism was applied. Torsional analysis reflecting the clutch mechanism as well as on-site strain gauge measurement verified its effectiveness. After implementation of this clutch, no malfunction or abnormality has been observed in the compressor train.
