压缩机密封件材质选择试验研究

In this paper the reciprocating hydrogen compressor seals material and filling material are summarized, through single factor experiment to explore the localization feasiblity of imported compressor seals made of PTFE material, obtained a suitable ratio of the filled PTFE self-lubricating materials, experiments showed that the localization of seals with good sealing performance, the hydrogen compressors system was made of these seals instead of imported seals, achieved an average repair cycle more than 7400h, proved its sealing performance reliability. And for half the cost of imported seals, the cost performance is 1.75 times of imported seals, greatly saving productive costs and improving productivity.
