... derived from statistical methods only capture certain characteristics of surface roughness at specific scales, such as the average height, distribution and dispersion. However, in high-contact performance applications, such as mechanical sealing, the limitations of these traditional methods have led...

...Yi Ma; Lei Chen; Yixiao Xu; Xiangkai Meng; Xudong Peng Purpose This study aims to evaluate the effects of the downhole environment and auxiliary rubber bellows on the contact mechanical characteristics and sealing performance of rubber-bellows mechanical seals (RBMS) in electric submersible pumps...

...Bill Wilson Summarizes briefly the dramatic advances made in the reliability of mechanical seals for rotating shafts in the process chemical and petrochemical industries over the last 30 years. Shows that expected mean time before failure has improved from tens of days to years over that time. ©...
