工程机械液压系统的现场故障诊断与维修技术研究

Research on field fault diagnosis and maintenance technology of hydraulic system of engineering machinery

工程机械在当前的工程施工中已经得到了广泛的使用,并且替代了大量繁重的人力劳动,这对施工企业来说,是一个重大的进步。在工程机械的动力系统中,大部分使用的都是液压传动系统,因此,液压系统的运转情况决定着整个机械系统运转健康与否,也是施工企业保持竞争力的重要条件。在实际的施工机械维护中,由于环境的不同以及技术上的限制,往往不能及时发现机械出现的问题和隐患。因此,本文将分析如何对施工机械的故障进行诊断,并提出几种行之有效的方法,以提高我国的施工企业在液压故障诊断与维护技术上的进步。

Construction machinery has been widely used in the current engineering construction,and has replaced a lot of heavy labor,which is a significant progress for construction enterprises.Most of the power systems in construction machinery are hydraulic transmission systems.Therefore,the operation of hydraulic system determines whether the whole mechanical system works well or not,and is also an important condition for construction enterprises to remain competitive.In the actual maintenance of construction machinery,because of the different environment and technical restrictions,it is often unable to find the problems and hidden dangers in time.Therefore,this paper will analyze how to diagnose the failure of construction machinery,and put forward several effective ways to improve the progress of hydraulic fault diagnosis and maintenance technology in China’s construction enterprises.
