| 摘 要： | 在往复式无油润滑压缩机装置上，试验研究了普通填充聚四氟乙烯(PTFE)、30%碳纤维增强PTFE和C/C+PTFE三种不同材料填料密封环的摩擦力、摩擦功率和摩擦温度。结果表明，普通填充PTFE材料的摩擦力受活塞平均滑行速度的影响最大，其摩擦功率和摩擦温度也最大。虽然C/C+PTFE的摩擦功率略高于30%碳纤维增强PTFE，但其摩擦温度比30%碳纤维增强PTFE低。由于C/C+PTFE具有非常良好的力学性能和较好摩擦特性，它有望成为高压、高速工作条件下的密封环材料。

| Abstract: | Triobological experiments are performed in a reciprocating oil-free compressor arrangement to investigate the friction force, power consumption and friction temperature of three materials of pressure packing seals. These rings are respectively made in common filled polytetrafluroethylene (Filled PTFE), PTFE filled with 30% carbon fiber (30% CF + PTFE), and carbon-carbon composites with PTFE infiltrated (C/C+PTFE). Tests are performed at mean piston speed of 0.4, 0.8, 1.2, 1.6, 2.0 m/s and under a sealing pr... |
