The service efficiency and service life of loaders are closely related to the management mode of users. Once the management is neglected, the abnormal loss of equipment will increase, resulting in the increase of failure rate and even hidden dangers. So, what are the bad situations in the current use of loaders?

装载机设备管理人员缺乏机械设备管理知识，对设备保养与维护认识不足。有些较好的设备，对配件的质量以及燃料、润滑油、液压油的质量要求较高，一些采购人员业务知识欠缺，责任心不强，购置了一些劣质配件和劣质油料，使一些较好的机械设备，由于使用了劣质配件和劣质油料，造成机械设备的早期损坏，降低了机械设备的使用效率。

Loader equipment managers lack mechanical equipment management knowledge and insufficient understanding of equipment maintenance. Some better equipment have higher requirements for the quality of accessories and the quality of fuel, lubricating oil and hydraulic oil. Some purchasers lack business knowledge and a strong sense of responsibility. They have purchased some inferior accessories and inferior oil, so that some better mechanical equipment will be damaged early due to the use of inferior accessories and inferior oil, It reduces the use efficiency of mechanical equipment.

由于各建筑工程施工现场条件比较复杂，环境比较恶劣，而且各管线沟槽比较混乱，加上设备多车辆多人员多，交通也不顺畅，而且工地一般都比较偏远，它在这种情形下很难做到及时系统的保养。

Because the construction site conditions of various construction projects are complex, the environment is bad, and the pipeline trenches are chaotic, coupled with many equipment, vehicles and personnel, the traffic is not smooth, and the construction site is generally remote, it is difficult to achieve timely and systematic maintenance in this case.

由于不够重视，贵重的一些矿用装载机结构件并没有及时配备专职保养人员，都是一些没有经过相关培训，多少知道一点机械工作原理的人员给机械做保养，这些人不熟悉工程机械保养的程序和要点，也不能很好地做好保养记录。

Due to insufficient attention, some valuable mining loader structural parts are not equipped with full-time maintenance personnel in time. They are personnel who have not received relevant training and know a little about the working principle of machinery. These people are not familiar with the procedures and key points of construction machinery maintenance and can not make good maintenance records.

此外，重要的一点源于企业的管理制度不够完整，没有能明确落实到人，造成机械设备管理工作混乱。或有制度而不能按制度执行，造成维护管理水平较低。

In addition, the important point is that the management system of the enterprise is not complete and can not be clearly implemented to people, resulting in confusion in the management of mechanical equipment. There may be a system but it cannot be implemented according to the system, resulting in a low level of maintenance and management.

装载机日常作业都需要油的润滑，那么安装如何避免油液的污染呢，下面一起来了解一下。

The daily operation of the loader needs oil lubrication, so how to avoid oil pollution during installation? Let's learn about it.

设备液压泵的吸油口应安装粗滤器，且吸油口处应距油箱底部相应距离；出油口处应安装高压精滤器，且过滤效果应按照系统的工作要求，以免污物堵塞而引起液压系统故障；装载机的液压油箱隔板上应加装过滤网，以除去回油过滤器未滤去的杂质。

The oil suction port of the equipment hydraulic pump shall be equipped with a coarse filter, and the oil suction port shall be at a corresponding distance from the bottom of the oil tank; High pressure fine filter shall be installed at the oil outlet, and the filtering effect shall be in accordance with the working requirements of the system to avoid the hydraulic system failure caused by dirt blockage; A filter screen shall be installed on the diaphragm of the hydraulic oil tank of the loader to remove the impurities not filtered by the oil return filter.

设备液压缸上应安装金属防护圈，以免污物被带进缸内，并可避免泥水和光辐射对液压缸侵蚀而引起泄漏；液压元器件安装前应检查、清理干净其内侧的铁屑及杂质；定期检查液压油，一旦发现油液变质、泡沫多、沉淀物多、油水分离等现象后应进行清洗系统并换油。

Metal protective ring shall be installed on the hydraulic cylinder of the equipment to prevent dirt from being brought into the cylinder and to avoid leakage caused by erosion of mud water and light radiation on the hydraulic cylinder; Check and clean the iron filings and impurities inside the hydraulic components before installation; Regular inspection of hydraulic oil, once the oil deterioration, foam, sediment and oil-water separation and so on, cleaning system and oil change should be carried out.

新油加入装载机的油箱前应经过静置沉淀，过滤后方可加入，需要时可设中间油箱以进行新油的沉淀和过滤，保障油液的清洁。

Before new oil is added into the oil tank of the loader, it shall be added after static sedimentation and filtration. If necessary, an intermediate oil tank can be set for sedimentation and filtration of new oil to ensure the cleanness of oil.
