Study on the model that can represent the shock vibration waveform of a reciprocating compressor when the linkage is worn out

(Vibration Model Used for Wear Monitoring)

Abstract

Reciprocating compressors are used to compress hydrogen gas, but it has been reported that each component wears out due to long-term continuous operation, resulting in a decrease in production. We have focused on the fact that the vibration of the compressor changes when each component wears out, and have attempted to monitor the wear by vibration. In this paper, I focused on the wear of the crosshead pin and created a mechanical model to reproduce the impact vibration caused by the phenomenon. As a result, I succeeded in generating two characteristic impact vibrations close to the experimental values in the model simulation. Using this model, I estimated the amount of wear, and although it did not match the actual amount of wear, I confirmed an increase or decrease in the amount of wear.
