摘要
对装载机液压系统进行正确的检修与保养,首先必须做好装载机日常保养和维护工作,在作业前后要按规定对装载机进行检查、保养和维护。在作业过程中,要注意装载机运行中有无不正常情况发生,如杂音、异味、振动等,发现问题及时做好必要的调整和修理工作,避免由于小故障的恶化而造成严重后果。
对筑路机械的检修与保养已有不少人提过,但仍有很多操作人员误以为只要勤换油及滤芯就万事大吉,以致液压系统出点小问题就不知所措。据查,当前因液压问题而瘫痪的筑路机械中有80%是装载机,且国产为多。
液压技术在装载机中应用日益完善,但客户对系统的可靠性要求也越来越高,为了保证装载机对液压系统各项技术指标和工作性能的要求,特别是对液压系统的检修与保养,必须对液压系统进行全面地分析,并掌握测试液压元件和系统的方法,进一步提高可维性和效率。

Abstract
On the loader hydraulic system for proper maintenance, you must first do the loader day-to-day maintenance and maintenance work, the operation and according to the provisions of the loader for inspection, maintenance and maintenance. During the operation, to the attention of loader operation there is normally occur, such as noise, smell, vibration, found problems in a timely manner to make the necessary adjustment and repair work, avoid because of the small fault deterioration and cause serious consequences.
On road construction machinery maintenance of many people mentioned, but there are still many operators mistakenly think that as long as the wash oil and filter is that everything will be fine. The hydraulic system, a little problem will be at a loss what to do. According to the investigation, the hydraulic problems and paralysis of the road construction machinery in the 80% loader, and for many domestic.
Application of hydraulic technology in loader is increasingly perfect, but customers on the reliability of the system are increasingly high requirements, in order to ensure loader hydraulic system of various technical indicators and performance requirements, especially for hydraulic system overhaul and maintenance of hydraulic syste
