Abstract: The levelness of large-scale compressor skid-mounted base was measured in the process of field installation and the causes of excess levelness were analyzed. Then two improvement schemes were proposed to reduce the levelness of the base; the solid model of the base was established; the levelness of the base was analyzed by adopting finite element method; the analysis results were compared with the measured results, thus the effectiveness of the improvement scheme was verified.

Key words: compressor, skid-mounted base, levelness, finite element analysis, improvement scheme
