The motor current fluctuation and the intake fault phenomenon and overhauling conditions of the 4M-20-177/22-BX reciprocating compressor of PSA unit in a refinery were described in detail in the paper. Then all design parameters of the thermal and dynamic calculation were accounted and checked. Checking thermodynamic calculations under different load conditions were carried out in order to analysis fundamental reasons of the failure combined with the calculation results. The improvements and sug-gestions for the compressor were judged finally.
