Analysis and Countermeasures for Short Service Life of Piston Rings and Support Rings in 4M16 Compressor
A 4M16 reciprocating compressor in a kerosene hydrofining unit of a petrochemical plant shows serious wear of the primary support ring and piston ring after only 49 days of operation after medium repair.In response to the phenomenon of short service life of the first stage support ring and piston ring of the reciprocating compressor,the author analyzes and studies the material,operating conditions,design dimensions,piston ring opening clearance,piston ring working temperature,cylinder water content,piston rod jumping,cylinder oil injection and cylinder mirror surface of the piston ring and support ring.The causes of short life of piston ring and support ring of 4M16 reciprocating compressor are analyzed,and corresponding corrective measures are put forward.After corresponding rectification of the influencing factors,the service life of the piston ring and support ring is effectively extended,the failure of the piston ring and support ring of the compressor is reduced,and the safety and stability of the plant production are ensured.At the end of the paper,the author puts forward six suggestions regarding the factors affecting the lifespan of piston rings and support rings,for reference of compressor equipment management personnel
