空气压缩机是工矿企业中应用最广泛的风动设备之一。在运转过程中,它对润滑油的消耗量大,常被人们称为“油老虎”。在石油供应日趋紧张的今天,节油是急需解决的重要课题之一。同时,因气体压缩,使活塞和气缸的温度高达110°～160℃,润滑油在这高温下,极易氧化结焦,若不及时清除,不仅影响气阀的正常开启,还有可能造成阀片早期磨损,阻塞、泄漏等故障,严重时还有引起自燃爆炸之危险。从安全生产和节约能源等方面考虑,我厂首先对沈阳气体压缩机厂早期生产的1-10/8型立式双缸空气压缩机的活塞环改用填充聚四氟乙烯进行了无油润滑试验。继后,又对1-40/8-2型立式双缸空气压缩机的活塞
Air compressor is one of the most widely used pneumatic equipment in industrial and mining enterprises. In operation, its consumption of lubricating oil, often referred to as “oil tiger.” In an increasingly tense oil supply today, fuel-saving is one of the important issues urgently needed to be solved. At the same time, due to gas compression, the piston and cylinder temperature as high as 110 ° ~ 160 ℃, lubricating oil at this high temperature, easily oxidative coking, if not promptly removed, not only affect the normal open valve, there may be caused by the valve Early wear, blockage, leakage and other failures, serious auto-ignition explosion also caused the danger of explosion. From safety and energy conservation and other aspects of consideration, I plant first of the Shenyang Gas Compressor Factory early production of 1-10 / 8 vertical twin-cylinder air compressor piston ring filled with PTFE for oil-free lubrication test. Followed by the 1-40 / 8-2 vertical twin-cylinder air compressor piston
