我厂氧气生产系采用分馏空气工艺,150立方米/时全套制氧设备大部分是五十年代的产品,全厂氧气年用量约36万立方米。一九七九年转产电力机车以来,工厂氧气用量减少致使成本较高。自推行全面质量管理以来,制氧小组围绕着提高氧气纯度和降低消耗这个目标,先后改革了间断制氧操作工艺,把停机保压的具体规定纳入操作标准;改善氧压机及连接管道状态,使出塔与装瓶氧气纯度差控制在0.12～0.15％范围内,通过采取上述措施使氧气瓶内的氧气纯度稳定
Oxygen production plant using Fractional Air Process, 150 cubic meters / hour when most of the full set of oxygen equipment is the product of the fifties, the whole plant oxygen consumption of about 360,000 cubic meters. Since the conversion of electric locomotives in 1979, a reduction in the amount of oxygen in the factories has resulted in higher costs. Since the implementation of total quality management, the oxygen making team has reformed the intermittent oxygen making process around the goal of improving the oxygen purity and reducing consumption. The specific provisions on downtime and packing are incorporated into the operating standards. The oxygen press and connecting pipelines are improved, So that the purity difference between tower and bottled oxygen is controlled within the range of 0.12-0.15%, and the oxygen purity in the oxygen cylinder is stabilized by adopting the above measures
