چکیده انگلیسی


• Frictional behaviors of the three sealing composites were compared.
• Sealing performance of different sealing materials was obtained by experiments.
• The effects of material properties on the sealing performance were investigated.
• Advantages and disadvantages of different sealing materials were identified.

This study investigated the frictional behaviors and sealing performance of three seal polymer materials. Tests were conducted on a special test rig of the sealing ring. Polytetrafluoroethylene (PTFE), polyimide (PI), and polyetheretherketone (PEEK) composites were tested in the test rig with a sealing ring configuration against the steel counter surface. Investigations through scanning electron microscopy revealed the wear patterns of the sealing composites and the nature of the fillers. Results indicated that the surface temperature and leakage rate of the PTFE, PI, and PEEK composites increased with speed under oil-lubricated conditions. Moreover, friction coefficient initially decreased with increasing speed, reached a minimum, and then increased with speed. The PTFE and PEEK sealing composites had lower friction coefficients, less leakage during testing, and superior properties than the PI sealing composite.
