This study presents a closed design model for mechanical seals, addressing common challenges in durability, leakage, and friction in rotating machinery. Mechanical seals are critical components in high-energy systems, such as turbines and pumps, where they prevent fluid leakage and withstand significant thermal and mechanical loads. Over time, factors like angular deformations and wear on the sealing rings lead to uneven pressure distribution, causing variations in performance and longevity.
To tackle these issues, the researchers developed a model that incorporates hydrodynamic characteristics, material deformations, and confusor gap shapes within the seal’s end surfaces. By evaluating the effects of different pressures and friction forces, the model ensures a stable, non-contact seal operation, minimizing wear and extending the lifespan of the equipment. This involves calculating expected leakage, friction power, and the seal’s resilience under various load conditions. The study also examines the pressure diagrams within the sealing gap, focusing on the relationship between reduced film thickness and increased hydrodynamic support.
One innovative aspect is the ability to predict wear and deformation patterns over time. This predictive capability aids in designing seals that withstand dynamic operating conditions, improving reliability for industries reliant on high-performance rotary equipment. The model’s practical applications can enhance the maintenance, safety, and operational efficiency of energy-intensive machinery, particularly in environments with high centrifugal forces and complex fluid dynamics.
