Rotor journal was relatively clean. Measurement revealed that it was worn out of factory tolerance. Also notice that there was no significant damage on rotor surface and rotor end. This indicates that the rotor did not hit suction bearing head. This compressor was pulled out of operation a minute before complete disaster, thanks to early problem detection by using vibration analysis and good data trending thereafter. After disassembling the compressor, internal condition was reported to operation manager with dimensional data sheet and pictures. This report would contribute to set up preventive measure to improve machine reliability.
