工程机械液力传动油性能要求及发展趋势

Performance Requirements and Development Trend of Hydraulic Transmission Oil for Construction Machinery

液力传动油作为工程机械核心部件中的工作介质,其性能需要满足很高的要求。该文对液力传动油的性能进行介绍,并对国内外液力传动油技术进行对比,特别是在液力传动油摩擦特性方面,目前,国内液力传动油技术较国外液力传动油技术还有一定的差距。

Hydraulic transmission oil is the working medium in the core components of engineering machinery,and its performance needs to meet high requirements.In this paper,the performance of hydraulic transmission oil is introduced,and the hydraulic transmission oil technology at home and abroad is compared.Especially in terms of the friction characteristics of hydraulic transmission oil,advanced foreign hydraulic transmission oil technology is still superior to that of domestic hydraulic transmission oil to some extent.
