High Vibrations & Component Failure in Turbomachinery due to Magnetic Currents : Its Detection, Diagnosis & Correction
Objective: To share with users of Turbomachinery the fact that High Speed Turbomachinery with components possessing Residual Magnetism can produce high shaft voltages & high current, which can lead to severe problem like high Vibrations, damage to the machine components. Scope: The Case Study details problem & diagnosis of the problem due to residual magnetism in Synthesis Gas Compressor at National Fertilizers Limited, Panipat Unit, INDIA. The problem lead to repeated overhaulings of compressor, replacement of three numbers of rotors, damage to number of bearings & Oil film seal rings.
