本文在大量试验的基础上,对无润滑往复活塞式动力压缩机密封元件用填充聚四氟乙烯的填充剂之一——玻璃纤维的要求、处理、加工以及在填充材料中的含量等进行了分析研究,提出了玻璃纤维经化学处理后再经表面处理剂处理可得到更为优异的性能的结论。在本文研究成果的基础上试制的填充聚乙烯密封元件,达到和超过了国内压缩机行业质量分等规定的优等品寿命指标不低于4000小时的要求。
In this paper, based on a large number of tests, the non-lubricated reciprocating piston compressor seal with PTFE packing one of the filler - glass fiber requirements, processing, processing and content in the filler material were Analysis and research, put forward the glass fiber chemical treatment and then treated by the surface treatment agent can get more excellent performance conclusion. Based on the research results of this paper, the trial-made filled polyethylene sealing element meets and surpasses the requirements of the excellent product life index of not less than 4,000 hours in the quality classification of the compressor industry in China.
