Sažetak
The paper presents the analysis of repeated shaft breaks on 560 kW electric motors coupled with reciprocating hydrogen compressors in oil refinery plant. Asynchronous electric motors and reciprocating compressors were coupled using elastic couplings. Torsional vibration calculations, performed during design, did not indicate any problems in compressor set operation. Design changes performed after initial breaks didn't help to keep the plant in safe operation. The paper presents the performed systematic analysis, showing the pitfalls encountered in torsional vibration calculations performed in usual way as used by manufacturer. Detailed analysis has indicated real causes of the breaks, not only one but few of them in very intriguing combination which had caused serious damages. The analysis was later applied to several manufacturers' solution proposals, helping to find the acceptable final solution. The paper indicate recommendations in performing torsional vibration analysis on such compressor drives.
