Abstract The vacuum degree of propylene refrigeration compressors is a key indicator to ensure the safe, stable and efficient operation of the units. A decrease in vacuum degree will significantly increase the steam consumption of the unit, affect economic benefits, and may cause problems such as intensified vibration and increased axial thrust. The main reasons for the decrease in vacuum degree of the propylene refrigeration compressor were analyzed. For these problems, a number of optimization measures were proposed. After the optimization of the device was implemented, the vacuum degree of the compressor was significantly improved, the steam consumption was reduced, and the economic benefits were remarkable.
