In order to research the life distribution type and reliability rules of centrifugal compressor, the method of data col-lection and analysis was used to determine the distribution type of the overhaul time. The preventive maintenance cycle and reliability rules of the equipment were further studied. The results show that the accuracy of Weibull distribution of three pa-rameters is better than Weibull distribution of two parameters according to the operation and maintenance data collected in the centrifugal compressors. The MTBF, MTTR and availability of the centrifugal compressors are 27 187 h, 489. 3 h and 98. 2% , respectively. The regular maintenance cycle of the centrifugal compressors is 9530 h under the reliability of 95% . The failure mechanism with high probability is in-service problems, and the failure units with high probability are seals in the centrifugal compressors.
