目前,世界上有美国、意大利、日本等国家能够生产年产52万吨尿素装置用二氧化碳离心压缩机。沈阳鼓风机厂在1982年10月试制完成、安装在浙江省镇海石油化工总厂,1984年5月经过闭式循环试车,一次获得成功,其性能完全达到设计和用户使用要求,填补了我国大型尿素装置用离心压缩机的空白,标志着我国离心压缩机设计、制造技术进入了一个新的阶段。这台二氧化碳离心压缩机是沈阳鼓风机厂按引进意大利新比隆公司技术,结合该厂多年来生产离心压缩机的经验,运用计算机进行了几十次计算,对十多个重大的计算方案中进行了分析比较,确定了最佳设计方案。该机组输送介质为CO_2气体,进口压比高达100,出口压力为144.3绝对大气压,出口流量为2940标 At present, the United States, Italy, Japan and other countries in the world can produce carbon dioxide centrifugal compressors with an annual output of 520,000 tons of urea plant. Shenyang blower factory trial in October 1982 completed and installed in Zhejiang Zhenhai Petrochemical Plant, in 1984 May after a closed loop test, a success, its performance fully meet the design and user requirements to fill our large urea Installation of centrifugal compressor blank, marking China’s centrifugal compressor design, manufacturing technology has entered a new phase. This Taiwan’s centrifugal compressor centrifugal blower plant in Shenyang, Italy, the introduction of the new Billumbi company’s technology, combined with the plant over the years the production of centrifugal compressor experience, the use of computers dozens of calculations, more than 10 major calculation programs The analysis and comparison, to determine the best design. The unit of transmission medium for the CO_2 gas, the inlet pressure ratio up to 100, the outlet pressure of 144.3 atm, outlet flow of 2940
