绿色环保型螺杆式空气压缩机用油的开发及应用

Research and Development Application for Performance of Green Screw Air Compressor Oil

针对螺杆式空气压缩机油在抗氧化、抗摩擦磨损性能以及油水分离等方面严格的性能要求,采用矿物油与合成油复配的基础油,通过添加合适的酚类抗氧剂、胺类抗氧剂、金属缓蚀剂、极压抗磨剂等功能添加剂,研发出一款抗氧化性能稳定和极压抗磨性能优异的螺杆式空气压缩机油。利用四球摩擦磨损试验机对其进行极压性能和摩擦磨损性能评价,并开展模拟氧化评价测试。结果表明,研制油品具有优异的抗氧化性能,能满足5000 h长换油周期,性能与进口专用油相当。

In view of the strict performance requirements of screw air compressor oil in oxidation resistance,f riction and wear resistance and oil-water separation,the base oil composed of mineral oil and synthetic oil was adopted,and appropriate phenolic antioxidant,amine antioxidant,metal corrosion inhibitor,extreme pressure anti-wear agent and other functional additives were added,and a screw air compressor oil with stable antioxidant and excellent extreme pressure and anti-wear was developed.The extreme pressure performance and friction and wear properties of the developed oil were evaluated on the four ball friction and wear test machine,and simulated oxidation evaluation test was carried out.The results show that the developed oil has excellent oxidation resistance,can meet the long oil change cycle of 5000 h,and its performance is equivalent to that of imported special oil.
