Abstract:

Mechanical sealing systems known as packed stuffing-boxes are widely utilized in pressurized valves and pumps. However, there is currently no established procedure for verifying their mechanical integrity and leak tightness. This study aims to address this issue by designing a stuffing box and creating a 3D model with NX UNIGRAPHICS 10. To evaluate the strength and durability of the model, structural and modal analyses are conducted using different materials, including Stainless Steel, Brass, and Grey Cast Iron. Additionally, a structural analysis of the packing gland and bush is performed for validation purposes. Finally, a comparison is made among the dissimilar materials to identify the optimal material for the stuffing box. The modelling is completed using NX UNIGRAPHICS 10, while the analysis is conducted with ANSYS, and the manufacturing process is accomplished using NX CAM
