2D氮氢压缩机是年产5000吨合成氨厂的主机,数量较多,分布甚广。近年来,我厂生产该机800多台,据全国十一个省、市统计,2D机约占主机总数的50％,数量达2200多台。如采用无油润滑技术,可以简化设备,降低成本,节省大量高级润滑油,保护触媒等。以前采用PTFE材料进行的试验,对四级环并不适宜。为了为小化肥生产多作贡献,1977年以来,由我厂、扶沟化肥厂、西平化肥厂共同对
2D Nitrogen Hydrogen Compressor is an annual output of 5000 tons ammonia plant host, a large number, widely distributed. In recent years, I plant more than 800 aircraft production units, according to the national eleven provinces, municipalities statistics, 2D machine about 50% of the total number of hosts, the number of more than 2200 units. Such as the use of oil-free lubrication technology, can simplify equipment, reduce costs, save a lot of high-grade lubricants, catalyst protection and so on. Previous tests using PTFE materials were not suitable for the four-stage ring. In order to make more contributions to the production of small-scale fertilizers, since 1977, our plant, Fugou Fertilizer Plant, Xiping Fertilizer Plant jointly
