二氧化碳压缩机轴瓦国产化改造研究

A RESEARCH ON HOME-MADE CO_2 COMPRESSOR BEARING

分析尿素装置二氧化碳压缩机轴瓦温度高、机组运行周期短的原因,提出机组轴瓦技术开发工艺路径并试验成功。二氧化碳压缩机轴瓦国产化成功解决了轴瓦温度高、机组运行周期短、进口备件采购周期长的问题,降低了备件消耗费用,打破了国外对该项技术的长期垄断。

The reasons of high temperatureon CO2 compressorbearing which causes the short operation cycle of the compressor in urea plant have been analyzed. A route for RD has been presented and succeeded in experiment, which solved the problems of high bearing temperature, short operation cycle and long term purchase from oversea, reduced the cost of spare parts, and broke the monopoly by foreign countries in passed years.
