Efficiency improvement of rotary compressors

The article discusses the issues of digital design of rotary gas compressors, identifies additive technologies for manufacturing parts and assembly units mastered by industrial enterprises abroad and in Russia using 3D printing with metal and non-metallic materials in various industries (including aircraft manufacturing and power engineering). We have analyzed the most promising materials, achievements and development trends, analyzed the experience of using air and gas rotary compressors, investigated metallic and non-metallic materials used for manufacturing rotary compressors. We have identified the main factors determining low cost indicators and efficiency of rotary compressors, determined the optimal parameters of gas compressors to effectively solve industrial problems, proposed design methods and manufacturing techniques reducing material consumption and increasing the strength of parts and components of compressors.
