一、试验目的遵照伟大领袖毛主席“备战、备荒、为人民”的伟大战略方针,大力支援农业,赶超世界先进水平,上海鼓风机厂承担了DA930—121空气透平压缩机的设计和试制任务。这台大型空压机是我国生产的三十万吨/年合成氨成套设备中的关键设备之一,任务较为艰巨,为了确保这台机组能够正常可靠运行,由上海鼓风机厂和清华大学精密仪器系于1975年7月联合对空压机的关键部件——高速径向滑动轴承进行了试验。杭州汽轮机厂和上海汽轮机厂也派人参加了试验工作。
I. Objectives of the trial To follow the great strategic principle of “preparing for war, preparing for waste and for the people” of Chairman Mao, vigorously support agriculture and catch up with the advanced world standards, the Shanghai Blower Factory undertook the design and prototype tasks of the DA930-121 air-turbine compressor . This large air compressor is one of the key equipment in the 300,000 tons / year ammonia plant in China. The task is arduous. To ensure the normal and reliable operation of this unit, Shanghai Blower Factory and Tsinghua University Department of Precision Instruments In 1975 July joint air compressor key components - high-speed radial plain bearings were tested. Hangzhou Steam Turbine Factory and Shanghai Steam Turbine Factory also sent participants to participate in the pilot work.
