摘　　要：在对活塞环的磨损特性分析的基础上,分别就活塞环的材质、工作温度、导向环和径长比对全无油润滑压缩机活塞环磨损的影响进行了探讨。可通过选用适宜的自润滑材料、较低的转速和径长比、设置导向环和降低活塞环的工作温度等措施,减小活塞环的磨损,提高使用寿命。以此开发的SW-2.5/7型全无油润滑压缩机上活塞环的使用寿命达8000h以上。The influences of piston ping material,work temperature,the guiding ring and radius-length ratio to wear of the piston ping were discussed respectively based on analysis about the wear characteristic of piston ping.The wear of the piston ping can be reduced and life can be improved by using suitable self-lubrication material,lower speed and radius-length ratio,setting guiding rings and reducing work temperature of the piston ping.The life of the piston ping used in the SW-2.5/7 oilless lubrication compressor developed as these methods is more than 8 000 h.
