四球法区分舰船汽轮机油抗磨性研究

DISCRIMINATION OF ANTI-WEAR PROPERTY OF MARINE STEAM TURBINE OIL BY FOUR BALL METHOD

在对比研究美国、俄罗斯军用汽轮机油产品规范中利用四球试验机法评定润滑油抗磨性的基础上,研究《润滑油抗磨性测定方法(四球机法)(SH/T 0189—1992)》和《润滑剂承载能力测定法(四球法)(GB/T 3142—1982)》对舰船汽轮机油抗磨性的内在规律及其区分性,并以FZG试验结果作为抗磨性评定依据,分析四球法与FZG试验法的相关性。结果表明:载荷越大,转速越低,摩擦环境越苛刻,越能区分不同油品的抗磨性能;标准SH/T 0189—1992(147N,1 200r/min)可以合理评价舰船汽轮机油抗磨性;最大无卡咬负荷PB对舰船汽轮机油具有明显的区分性,能够较好地表征油品的抗磨性能。

On the basis of the comparative study of the anti-wear property specification for the United States and Russian military turbine oil products by four ball method,the internal laws and discrimination of the anti-wear property of marine steam turbine oil were studied through“Lubricating oils determination of anti-wear by four ball method(SH T 0189-1992)”and“Lubricants-determination of load-carrying capacity by four ball method(GB T 3142-1982)”.The correlation of four ball method and FZG was analyzed based on the FZG results.The results showed that the larger the load,the lower the rotational speed,and the more stringent the friction environment is,the more obvious distinguish for the anti-wear properties of different oils;SH T 0189-1992(147 N 1 200 r min)can reasonably evaluate the anti-wear property of marine steam turbine oil.The maximum nonseizure load P B value has obvious distinction between marine steam turbine oils and can represent the anti-wear properties of oil products.
