随着液压传动和液力传动技术在工程机械上的广泛应用,对液压系统的性能提出了愈来愈高的要求。提高工程机械液压系统的工作可靠性和使用寿命愈来愈引起人们的关注。大量事实表明,工程机械的故障和工作可靠性与液压系统污染状况有着极为密切的关系。
With the hydraulic transmission and hydraulic transmission technology widely used in construction machinery, hydraulic system performance put forward higher and higher requirements. Increasing the working reliability and service life of the hydraulic system of construction machinery has drawn more and more attention. A large number of facts show that the construction machinery failure and reliability of the hydraulic system has a very close relationship between pollution.
