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。那么应该如何维护升降机的液压系统呢？
1、使用与自己设备相符合的液压油
在液压系统中液压油的作用巨大，比如冷却、密封等等，如果使用不适当的液压油则很有可能在使用初期就会导致液压系统出现异常。而且，型号不同的液压油不可混用，以避免两种不同的液压油发生反应，如果发生深褐色、乳白色，有异味及时更换液压油。
Role in the hydraulic system of hydraulic oil giant, such as cooling, sealing, etc., if you use inappropriate hydraulic oil is likely during the initial period will lead to a hydraulic system malfunction. Moreover, different models of hydraulic oil can not be mixed in order to avoid two different hydraulic fluids react, if there is a dark brown, white, smelly timely replacement of hydraulic oil.
2、避免液压系统中进入杂物
The normal operation of the hydraulic system must use pure hydraulic oil, hydraulic system should pay attention to conservation: first remove the oil cap on the fuel tank and tubing, made ?in the system during the oil road dust around the outside to avoid attention attached to tubing on dismantling parts should open its first clean.
3、防止空气和水入侵液压系统
液压油泵的吸油管口不得露出油面，吸油管路必须密封良好。油中含有过量水分，会使液压元件锈蚀、油液乳化变质、润滑油膜强度降低，加速机械磨损.除了维修保养时要防止水分入侵外，还要注意储油桶不用时，要拧紧盖子，最好倒置放置。
Hydraulic pump suction nozzle shall not expose the oil, the suction line must be sealed well. Oil contains excess moisture, hydraulic components will rust, oil emulsion deterioration, reduced lubricant film strength, speed mechanical wear. Except when maintenance to prevent moisture intrusion, but also pay attention to oil tank when not in use, to tighten the lid, the most good upside down.
4、作业中注意事项
机械作业应避免粗暴，否则必然产生冲击负荷，使机械故障频发，大大缩短使用寿命。液压升降平台作业时产生的冲击负荷，一方面使机械结构件早期磨损、断裂、破碎，一方面使液压系统中产生冲击压力，冲击压力又会使液压元件损坏、油封和高压油管接头与胶管的压合处过早失效漏油或爆管、溢流阀频繁动作油温上升。
Mechanical operations should avoid rough, otherwise inevitably have an impact load, so that mechanical failure-prone, greatly shorten life. Shock loads generated when the hydraulic lift platform operations, on the one hand the mechanical structure of early wear, fracture, broken, on the one hand to make an impact in the hydraulic system pressure, impact pressure and cause damage to the hydraulic components, seals, and high pressure tubing and hose fittings lamination of the premature failure of the oil spill or burst pipes, frequent relief action oil temperature rise.
