据有关资料统计,每年全世界仅用于车辆的润滑油就达4～5千万t,而车辆用油占润滑油总用量的百分之四十左右。据此估计,目前全世界润滑油总耗费量每年至少达一亿吨以上。可以说,只要有机械运转的地方几乎无可避免地要使用润滑油。由于润滑油的耗费量如此巨大,因此,了解润滑油劣化基理,正确掌握使用方法,将对国民经济起到重要作用。1润滑油的劣化及产生的影响现代社会中运行着各种各样的机械设备,它们的运行和操作条件各不相同,因而对 According to the statistics, only 40 to 50 million tons of lubricating oil are used for vehicles in the world each year, while vehicle oil accounts for about 40% of the total amount of lubricating oil. It is estimated that the total consumption of lubricants in the world at least 100 million tons per year or more. It can be said that as long as there is a mechanical operation where it is almost inevitable to use lubricants. As the consumption of lubricating oil is so huge, understanding the basis of lubricant deterioration and correctly using the method will play an important role in the national economy. A lubricant deterioration and the impact of Modern society, running a variety of mechanical equipment, their operating and operating conditions vary, so
