一、概况为了保证国内自行设计试制的30万吨/年合成氨厂设备可靠、顺利地投入生产,上海第一冷冻机厂和合肥通用机械研究所共同承担了ALS-16000型氨透平冷冻机径向轴承的设计试验工作,设计中采用了五瓦块可倾垫块式轴承。它具有抗油膜振荡性强,对工况变动适应范围广,对固体夹杂物不敏感,能较好地吸收振动等优点。合肥通用机械研究所承担了试验轴承的设计工作以及径向轴承试车台的设计、制造、安装调试和轴承的试验测定工作。上海第一冷冻 I. Overview In order to ensure reliable and smooth production of a 300,000 tons / year ammonia plant in China, Shanghai No.1 Freezing Machine Factory and Hefei General Machinery Institute jointly assume the ALS-16000 Ammonia Turbine Freezing Machine Diameter To the design of the bearing test work, the design uses a five-tile tilting pad bearings. It has anti-oil film oscillation, to adapt to a wide range of changes in conditions, are not sensitive to solid inclusions, can better absorb vibration and so on. Hefei Institute of General Machinery bear the design of test bearings and radial bearing test bench design, manufacture, installation and testing of bearings test determination. Shanghai first frozen
