我厂生产的3L-10/8型空气压缩机,在国内使用的已有五千余台。一些单位曾向我们提出了少油化的要求,某些单位亦作过此方面的改进和试验,获得了一些效果。例如湖南岳阳化工总厂、南京电子管厂等,将活塞环与密封填料改用自润滑的填充聚四氟乙烯材料后,取消了压缩机的注油器;南京化纤厂还在一、二级活塞上增加了导向环;南京钟山化工厂曾将金属环状气阀改变为用聚四氟乙烯板制成网状的塑料气阀等等。结合这些单位的改进试验 I plant the production of 3L-10/8 air compressor, used in the country has more than 5,000 Taiwan. Some units have submitted to us the request for less oil and some units have also made improvements and tests in this respect and achieved some results. For example, Hunan Yueyang Chemical Plant, Nanjing Electronic Tube Factory, the piston ring and sealing filler switch to self-lubricating PTFE filler material, canceled the compressor lubricator; Nanjing Chemical Fiber Factory is still on the first and second piston An increase of the guide ring; Nanjing Zhongshan Chemical Plant once the metal ring valve into a polytetrafluoroethylene mesh made of plastic valve and so on. Combined with the improvement of these units test
