Abstract

Many enterprises are engaged in modernization of compressors in connection with increase of requirements to quality of carbon dioxide. In a basis of this work is transfer of cylinder-piston groups of multistage compressors on «dry» compression in them of carbon dioxide. A creation of durable and effective piston gaskets from nonmetallic rings represents a problem, is especial in compressor steps of high pressure. The mathematical model is created for studying the contribution of various factors in serviceability of gaskets. The calculations have shown that differences of pressure on rings of gaskets appear different and considerably distinguished. The original constructive decisions are described, allowing to lower loadings on first and last elements of gaskets. Examples of successful modernization of carbon dioxide compressors of high pressure are resulted.
