![]() ![]() When troubleshooting reciprocating compressors, the most important symptoms to watch for are unusual sounds and changes in pressures, temperatures, and flow rates. ![]() Inadequate clearance will ultimately lead to piston failure or rod breakage with attendant damage to the crosshead. Similarly, it would be a mistake not to respond to such audible symptom as “knocking in cylinder,” where the most probable cause is inadequate piston-to-head clearance. ![]() Not responding to this cause will lead to an overheated cylinder and ultimately to such events as piston seizure, ring breakage, and piston cracking. This fact becomes quite clear when considering how the neglect of subtle performance changes can result in costly wrecks.įor example, high discharge temperatures can result from the simple primary cause of insufficient coolant supply. F ew pieces of petrochemical process machinery lend themselves more readily to early symptom-cause identification than reciprocating compressors. ![]()
