In the polysilicon production process, the pressurization of key process gases such as hydrogen and chlorosilanes primarily relies on piston compressors. This paper systematically elaborates on the structural characteristics of piston compressors and conducts a statistical and analytical examination of the causes of three common types of failures observed in the piston compressors used by a certain polysilicon production enterprise. Four optimization measures are proposed, including reducing the dust content in the compressed medium, enhancing the efficiency of packing seals, strengthening operational management capabilities, and optimizing the rational selection of equipment. The implementation results demonstrate that these measures have effectively reduced the failure rate of plunger compressors by 83.33%, significantly enhancing the safety and stability of the polysilicon production system, thereby bringing substantial safety and economic benefits to the production enterprise.
