铁路螺杆式空气压缩机油的研制

为适应铁路新型客运机车装用螺杆式空气压缩机的需要,研制螺杆式空气压缩机油。经室内配方筛选、室内理化性能综合评定、现场运用装车试验,确定出研制油以聚a 烯烃(PAO)为主、酯类油为辅的复合合成油为基础油,加入一定比例的抗氧剂、防锈防腐蚀剂、抗磨剂、破乳剂、抗泡剂等多种添加剂,并严格按照试验确定的工艺调配而成。经室内理化性能综合评定,研制油倾点低,氧化安定性能、抗泡性能、抗乳化性能、防锈防腐蚀性能优异。经1年现场运用试验,研制油具有更好的抗乳化性和空气释放性,具有相当的抗磨性、氧化安定性。

Development of Screw Air Compressor Oil for Railway Locomotive

Screw air compressor oil is developed to meet the requirement that the new type railway passenger locomotive be equipped with screw air compressor. After indoor formulation and filtration, indoor comprehensive evaluation of the physicochemical performance and field operation loading tests, etc., the synthetic oil has been selected as the base oil for research oil, which is compounded from primarily poly a-olefin (PAO) and subordinately ester. Strictly following the technology obtained from the tests, such oil is mixed with adding certain proportion of various additives such as, anti-oxidation, anti-rusting, anticorrosive, anti-abrasion, anti-emulsion and defoaming agents, etc. After the comprehensive assessment on indoor physiochemical performances, it is found that the research oil possesses such advantages as, low solidifying point, oxidation invariability and excellent performances as, defoaming, anti-emulsification, anti-rusting and anticorrosion. After a year in situ application test, the research oil shows better anti-emulsification and air release. It has considerable anti-abrasion and oxidation invariability.
