...Xueguang Kan; Yuankun Zheng; Heyun Bao; Zouhao Song; Yu Xu Purpose Frictional heat generated by high-speed friction of aerospace mechanical seals induces temperature rise of the sealing rings and end face thermal deformation, and even leads to seal failure. This paper aims to conduct research...

... and material properties in predicting leakage rates. At the interface of mechanical seals, microscopic forces such as van der Waals forces and capillary forces play a significant role in leakage behavior. Zheng et al. (2023) developed an interface leakage theory that considers these microscopic...

...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. ©...

... Describes computer software derived from tests on seals which enables life prediction. List explosive decompression and material degradation of down well O rings, fatigue crack growth of diaphragms and mechanical seal performance as subjects covered. © MCB UP Limited 1994 Diaphragm...
