随着内燃牵引比例的不断提高,机车柴油机用14号润滑油需用量也不断增大。因此,把柴油机上换下来的废14号润滑油再生利用,不仅可以节约大量的新油,降低运营费用,而且可以减少废油对环境的污染。昆明机务段于1971年着手进行润滑油再生工艺的比较和选定工作。经多次模拟试验,选用“沉淀脱杂、酸洗、蒸馏白土精制(即带土
With the continuous increase of the ratio of internal combustion traction, the amount of lubricating oil required for locomotive diesel engine No. 14 has also been increasing. Therefore, the replacement of diesel on the 14th waste oil recycling, not only can save a lot of new oil, reduce operating costs, but also reduce the pollution of waste oil on the environment. Kunming Locomotive Depot in 1971 to proceed with the comparison and selection of lubricant regeneration process. After many simulation tests, the selection of "precipitation dedoration, pickling, distillation clay purification (ie soil
