碩士 === 正修科技大學 === 機電工程研究所 === 98 === This study was carried out for analyzing the mechanical and sealing properties of spiral wound gaskets in order to assist the gasket manufactures to insure quality and make process improvement. Through systematic experiments, such as gasket compression and recovery test (according to GB/T12622-2008 test method B) and sealing performance (according to GB/T12385-2008 test method A), the effect for different structures and process parameters of spiral wound gasket on mechanical and sealing performance can be elucidated. The compression and recovery test results show that the current manufacturing quality of spiral wound gasket does not reach the industrial standard; the spiral wound gaskets with different fillers indicate diverse nature of mechanical and sealing properties. The sealing performance test results show that there are relationships between gasket stress and leakage rate、medium pressure and leakage rate. Basically, the greater the gasket stress and the smaller the medium pressure, the smaller the leakage rate. The testing results will be useful to gasket manufacturers for modifying the structural design and adjusting the process parameters of gaskets.
