SW-2.5/7型风冷全无油压缩机的密封与润滑技术
Sealing and Lubricating Technology of SW-2.5/7 Air-cooling Non-lubricated Air Compressor
【摘要】 介绍了SW 2 5 / 7型风冷全无油压缩机的研制过程中 ,填充聚四氟乙烯 (PTFE)活塞环和导向环的选材与结构设计。对气缸和轴承的密封与润滑进行了探讨 ,并提出了全无油润滑压缩机的径长比 (λ =r/l)与配合间隙的合理选择范围
【Abstract】 The structure design and material selection of the piston rings and guiding rings made by PTFE are introduced in SW 2 5/7 air cooling non lubricated air compressor It is discussed about sealing and lubricating of the cylinder and bearing The reasonable selection range of fit clearance and radius length ratio for non lubricated air compressors is given
