What are the specific symptoms during operation when the piston rings of a reciprocating compressor are worn?

Or rather, how can one determine if the piston rings are worn?
In cases of abnormal wear, the outlet pressure fails to rise, the air injection volume drops sharply, overpressure occurs in the upstream section, there is a sound of gas leakage inside the cylinder, the temperature rises abnormally, which can lead to damage to the piston skirt, the packing starts to smoke, the cylinder becomes bulgy, and the piston rod may break.
Could it cause larger fluctuations in the stress of standing out?
Recently, the export pressure gauge has been showing significant fluctuations. I’m not sure what the reason is
Before the New Year, one of our reciprocating compressors suffered severe wear on both its piston rings and support rings; as a result, it was unable to handle any load and did not perform any compression work. If the wear hadn’t been severe, there might have been a decrease in outlet pressure.
It’s best not to try to determine this; instead, carry out maintenance in advance based on the service life specified by the manufacturer. It’s also advisable to revise this service life during the production process. If damage occurs, it can affect the overall service life of the equipment or even cause direct damage to it. If it causes a top cylinder issue,,,
Wear of the piston rings, rather than that of the support rings, does not affect the movement of the piston. However, it causes gas leakage during the piston’s movement – the compressed, high-pressure, high-temperature gas leaks to the side of the piston where intake is taking place. As a result, the outlet temperature rises, the outlet pressure fluctuates, and the flow rate decreases; there may also be an audible sound indicating gas leakage
