Investigates sealing performance under temperature influences in hydraulic-driven piston compressors, suggesting material improvements.
Key Points
The aim is to evaluate the sealing performance and wear characteristics of spring-energized seals to enhance their service life under oil-free conditions.
Developed a thermal-structural coupling simulation model
Conducted wear tests over 150 hours
Analyzed the impact of temperature on sealing performance
The coupling simulation model reduced strain calculation error to 8.296% compared to 20.32% for the single model
2.58% error in wear prediction reflects high model accuracy
A 60 °C rise in discharge temperature correlates with a 14% reduction in seal life
