RECIPROCATING COMPRESSION APPARATUS

摘要

To simplify a configuration for returning to uncompressed gas a lubricant separated from gas discharged from a compression chamber, while effectively using the lubricant , a reciprocating compression apparatus includes: a cylinder; a piston disposed in the cylinder to form a compression chamber therein; a drive section for generating drive force for reciprocating the piston in the cylinder; a separator for separating a lubricant from gas discharged from the compression chamber; and a return line for returning the lubricant separated in the separator to a return destination where gas containing the lubrication is present and a pressure is lower than that in the separator. The return line includes a lubrication cooling unit for cooling the lubricant flowing through the return line and a drive section cooling section for cooling the drive section with the lubricant which has been cooled in the lubricant cooling unit 35.
