(一)试验结果部分随着我国石油,化学工业和石油化工工业的迅速发展,对制冷用透平压缩机的需要日益增加。制冷机械战线上的广大职工,本着“独立自主,自力更生”的精神,积极发展新产品,新品种,以满足国民经济发展的需要。根据我国炼油厂规模愈来愈向大容量发展的要求,一机部决定由北京冷冻机厂和合肥通用机械研究所参考某国进口的一台蒸发温度为-20℃,冷凝温度为+36℃,容量为250万大卡/时氨透平压缩机,自行设计蒸发温度为-20℃,冷凝温度为+38℃,容量为500万大
(A) Experimental Results With the rapid development of China’s petroleum, chemical industry and petrochemical industry, the need for refrigeration compressor turbines is increasing. The majority of workers on the refrigeration machinery front line actively develop new products and new varieties to meet the needs of national economic development in the spirit of “independence and self-reliance”. According to China’s oil refinery size more and more to the requirements of large-capacity development, a machine decided by the Beijing Refrigeration Factory and Hefei General Machinery Research Institute imported a country evaporation temperature of -20 ℃, condensing temperature of +36 ℃, A capacity of 2.5 million kcal / hour ammonia turbine compressor, self-designed evaporation temperature of -20 ℃, condensing temperature of +38 ℃, a capacity of 5 million large
