| description | Pneumatic cylinders are critical components in automated and semi-automated production systems, often employed to replace manual labor. However, their service life can be limited under demanding conditions involving heavy and repetitive loads. This study investigates the selection of optimal seal materials for pneumatic cylinders operating under such conditions to enhance service life and reduce maintenance costs. The performance of pneumatic cylinders is significantly impacted by friction-induced heat and subsequent thermal deformation of the seals, leading to increased wear and lubricant degradation. This research employed a combined simulation and experimental approach. Finite element analysis (FEA) using Ansys software was used to model heat distribution within the cylinder and seal assembly. Experimental testing involved cycling pneumatic cylinders with different seal materials (ordinary rubber, NBR rubber, and PU rubber) under simulated operating conditions. Results indicate that ordinary rubber seals failed after 13,250 cycles due to excessive wear. NBR rubber seals demonstrated improved durability, achieving 162,000 cycles before requiring maintenance. PU rubber seals exhibited the highest durability, exceeding 220,000 cycles without significant degradation. These findings highlight the critical role of material selection in improving the longevity and reliability of pneumatic cylinders in demanding industrial applications. The research provides valuable insights for engineers seeking to optimize pneumatic system design and reduce operational downtime. |
