Application Number: JP,2022-170706
Category (FI): F04B39/00,107@J
Stage: PROBLEM TO BE SOLVED: To provide a method capable of evaluating a service life of a piston ring in which the same can maintain sealing performance for a long operation period without including PPS.SOLUTION: A method for evaluating a service life of a piston ring used for a reciprocating compressor includes: investigation of a correlation of operation hours of the reciprocating compressor with pressure inside a space affected by a pressure increase due to a leakage of compressed gas through a gap between the piston ring and a cylinder body; determination of the operation hours with which the pressure inside the space reaches a predetermined threshold based on the correlation; and evaluation of the determined operation hours as the service life of the piston ring.SELECTED DRAWING: Figure 2 (Grant)
