摘要
将Ｌ型空压机有油润滑改造为换代的无油润滑空压机，采用复合型填充ＰＴＦＥ新材料的活塞环和带卸荷结构的导向环，不但使用性能与国内同类机型相同，且导向环。
The oil lubrication of L type air compressor is rebuild to oilless compressor of comming generation.The piston ring of new material complex filler PTPE,and guide ring with unloading structure are adopted.So that,not only its operating performances are the same as domestic identical compressor,but the service life of guid ring and piston ring are increased by several times.
