Reliability analysis of ЭС2Г series compressor train units at the beginning of operation

Abstract

The article considers reliability analysis of compressor screw units on electric trains of ЭС2Г series on the basis of information received on operating time between failures from the beginning of operation. The combined recovery process and recovery function are plotted, and the fault flow function is calculated and constructed. Conclusions on the reliability of the considered equipment are drawn on the failure flow function. At the beginning of operation of these compressor units a number of failures occurred related to the run-in period. The manufacturer took into account all cases of incorrect operation and made changes in the design and electrical control circuits, which allowed reducing the probability of failures many times in the future. In the future, the present results can be usefully applied to calculate the distribution function and estimate the 90% resource.
