摘要
分析了原密封的失效原因,介绍了新密封的结构、原理和特性。新密封用于某厂10万吨甲醇装置的天然气压缩机上,改造后已运行37个月,没有工艺气泄漏,运行情况良好。
The structure, mechanism and characteristic of the new seal is introduced and the failure reason for the mechanical floating ring seal is analyzed. The dry gas seal is applied on the natural gas compressor of 100kt/a methanol device of Sinopec Sichuan Vinylon Works. It is an alternative of the home - made combined floating ring seal. The design life of the primary seal is no more than a year; after improvement, the seal has already worked 37 months without leaking.
