船舶高粘度空压机油的研制

Development on naval vessel high viscosity air-compressor oil

进口船舶专用空压机上使用一种高粘度空压机油。该油品国内无成熟产品可替代,为了满足该类空压机的用油需求,必须对这种高粘度空压机油进行国产化研制。研究中根据进口空气压缩机组工作条件和国外相应油料技术要求,制定了国产油料的产品规范,并以聚α-烯烃合成油和加氢矿物油复合为基础油,通过加入多种功能添加剂,研制了一种新油品。通过理化性能试验、积炭生成倾向台架试验和使用寿命全尺寸台架试验,对研制油品和进口油料进行了对比试验。试验结果表明,研制产品理化性能达到了进口产品指标要求,积炭倾向性符合L-DAB标准要求,使用寿命达到中高负荷往复式空压机油所规定的换油周期和使用要求,研制油品综合性能完全达到国外同类参比油的性能,满足进口空压机的使用要求,可代替进口油料在引进装备上使用。

According to naval vessel reciprocating air-compressor working condition, a kind of naval vessel high viscosity air-compressor oil was developed with PAO and hydrogenation crude oil as base stock, and mixing with multiple purpose additive packages. The physico-chemical properties of the developed oil reach the imported product standard. The result of the coke bench experiment shows that the developed oil achieves the L-DAB compressor oil grade. It can meet the requirements of imported naval vessel heavy-duty reciprocating air-compressors.
