现代装载机、铲运机等工程机械的主传动系统均普遍采用了液力、液压传动技术,并随着机-电-液一体化技术的应用,该系统已逐步向集成化、大功率和自动化方向发展。但随之而来的是维修技术复杂程度高,故障原因隐蔽,故障诊断与排除较难。要管理与维修好这些工程机械,就必须做到: (1)对大型工程机械推行“定点-定项”的视情维修制,全面开展定期状态检测,随时发现故障隐患,及时诊断、排除。 (2)定期进行油品检测,建立各部位使用油品档案,实行油品的选购、保管、使用、添加、更换和废油处理等全过程管理,变定期换油为按质换油,加强液力、液压传动系统的防污染控制。
Modern loader, scraper and other construction machinery drive systems are generally used hydraulic, hydraulic transmission technology, and with the machine - electricity - liquid integration technology, the system has been gradually integrated, high power and Automated direction of development. However, followed by the maintenance of high technical complexity, concealed reasons for failure, fault diagnosis and troubleshooting more difficult. To manage and repair these construction machinery, we must do the following: (1) Carry out the “condition-fixed item” condition-based maintenance system for large-scale construction machinery and carry out regular state inspection in an all-round way so as to discover the hidden trouble at any time and diagnose and eliminate it in time. (2) Carry out regular testing of oil products, set up oil files for all parts, implement the whole process of oil purchase, storage, use, addition, replacement and disposal of waste oil, and change oil periodically to change oil by quality, Strengthen hydraulic, hydraulic transmission system pollution control.
