PISTON RING, RECIPROCATING COMPRESSOR, METHOD FOR SELECTING PISTON RING AND METHOD FOR EVALUATING LIFE OF PISTON RING

ABSTRACT A piston ring is used for a reciprocating compressor. In the piston ring, polytetrafluoroethylene and polyetheretherketone or polyimide account for 50% or more by mass in total. The piston ring does not contain polyphenylene sulfide. The piston ring has a tensile strength within a range of...

Zusammenfassung:	ABSTRACT A piston ring is used for a reciprocating compressor. In the piston ring, polytetrafluoroethylene and polyetheretherketone or polyimide account for 50% or more by mass in total. The piston ring does not contain polyphenylene sulfide. The piston ring has a tensile strength within a range of more than 15 IVIPa and less than 100 MPa. CA 3132851 2021-10-01
