我厂有5台3Z3.5-1.67/150型氧气压缩机,在使用过程中一级活塞经常出现冲击现象,严重时造成机身振动异常,机器不能正常运行,生产中每隔两个月就需要停机检修活塞一次。 原因分析 1.氮气经氧压机压缩后的温度达100 C以上,该状态下的氧气对铝有着强烈的氧化作用。在铝活塞表面形成的氧化层阻止了继续氧化,而活塞沉孔在活塞 I plant 5 sets of 3Z3.5-1.67 / 150 oxygen compressor, a piston in the course of the impact of the phenomenon often occurs, causing severe body vibration abnormalities, the machine can not be normal operation, the production of every two months on Need to shut down the maintenance piston once. Analysis 1. Nitrogen compressed by the oxygen compressor temperature of 100 C or more, the state of oxygen on the aluminum has a strong oxidation. Oxide formed on the surface of the aluminum piston prevents further oxidation and the piston countersinks in the piston
