新氢压缩机填料密封故障分析及改进

The Packing Seal's Failure Analysis and Improvement for New Hydrogen Compressor

介绍新氢压缩机填料密封的结构与原理。针对该型压缩机密封填料使用寿命短、密封效果不佳的状况,分析填料密封失效的主要原因,得出影响压缩机填料密封寿命的主要因素,在不改变填料盒结构的前提下,从密封组件的结构设计和材料选用等几个方面对密封填料提出具体的改进措施。

The packing seal structure and principle of new hydrogen compressor were introduced. Aimed at the problem that this type of compressor＇ s packing seal of short working life and the seal effect not well, the main reason which caused the seal packing failure of the compressor was analyzed, the factors influence the seal packing service life was obtained. On the premise of not altering the filler＇ s structure, the specific improvements for the seal packing were offered from the aspects of the structure design of seal packing component and the selection of materials.
