    升降机对机械化施工企业来说,工程机械技术状况的良好与否是企业能否正常生产的直接因素。就液压传动的工程机械而言,液压系统的正常运行是其良好技术状况的一个主要标志。合格的液压油是液压系统可靠运行的保障,正确的维护是液压系统可靠运行的根本。为此,济南赛力根据工作实践,就一般作业环境中工程机械液压系统的维护作粗略的探讨。

    选择液压油

    液压油在液压系统中起着传递压力、润滑、冷却、密封的作用,液压油选择不恰当是液压系统早期故障和耐久性下降的主要原因。

    防止杂质混入

    清洁的液压油是液压系统的生命。液压系统中有许多精密的偶件,有的有阻尼小孔、有的有缝隙等。若固体杂质入侵将造成精密偶件拉伤、发卡、油道堵塞等,危及液压系统的安全运行,一般固体杂质入侵液压系统的途径有:液压油不洁;加油和维修、保养不慎;液压元件脱屑等。

Lift for mechanized construction enterprises, the technical condition of construction machinery is a direct factor of normal production. As far as hydraulic transmission engineering machinery is concerned, the normal operation of hydraulic system is a major sign of its good technical status. Qualified hydraulic oil is the guarantee of reliable operation of hydraulic system, and correct maintenance is the fundamental of reliable operation of hydraulic system. Therefore, according to the work practice, the maintenance of hydraulic system of construction machinery in general operating environment is roughly discussed.
Selective hydraulic oil
Hydraulic oil plays the role of transferring pressure, lubrication, cooling and sealing in hydraulic system. Improper selection of hydraulic oil is the main reason for early failure and durability decline of hydraulic system.
Prevent impurities from mixing
Clean hydraulic oil is the life of hydraulic system. There are many precision coupling parts in the hydraulic system, some have damping holes, some have gaps and so on. If solid impurities invade will cause precision couple pull, hairpin, oil channel blockage, etc., endanger the safe operation of the hydraulic system, general solid impurities invade the hydraulic system way is: hydraulic oil unclean; Careless refueling, repair and maintenance; Hydraulic components chip removal, etc.
