Set Up

Piston ring is one of the most important sealing components that can be easily damaged in reciprocating compressors. The severe non-uniformity of the pressure distribution was suggested to be the essential reason for the premature failure of the piston rings. Therefore, a test rig was set up to measure the pressure distributions as well as the build-up of the dynamic pressure difference, which could reveal the root cause for the non-uniformity of the pressure distributions. The results showed that the build-ups of the pressure differences between different rings were not simultaneous; there existed a threshold pressure, and the latter ring could work only when the pressure before the former ring reached to the threshold value. The pressure distributions were also investigated at the start-up and shut-down of the compressor, which further validated the cause of the premature failure of the first ring.

Literature Reading

The pressure on the wagon body is generated for stochastic vibration of train or vehicle. The value and variation of this dynamic pressure are great significance in the study of the fatigue strength of the wagon body. This paper reviews the various influencing factors of the pressure distribution and also summarizes its simulation and prediction method based on the sufficiently literature reading.
