Abstract
Purpose
This study aims to investigate the dynamic characteristics of a high-speed mechanical seal by considering the flow regime, cavitation phenomenon and inertia effect.
Design/methodology/approach
Based on the high-speed conditions of a mechanical seal with a low-viscosity fluid, a multi-factor coupled lubrication model of a mechanical seal is established. The perturbation Reynolds equation set is derived using the perturbation method, and the effects of turbulent flow and inertia on sealing performance are discussed.
Findings
The results indicate that turbulence significantly influences the dynamic characteristics of low-viscosity fluids under high-speed conditions.
Originality/value
The results of the dynamic characteristics presented in this study are expected to provide guidance for the design of mechanical seals.
