求翻译：防止水入侵液压系统油中含有过量水分，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；含水量大的油要经多次过滤,每过滤一次要更换一次烘干的滤纸，在没有专用仪器检测时，可将油滴到烧热的铁板上，没有蒸气冒出并立即燃烧方能加注。是什么意思？

Oil hydraulic system to prevent water intrusion contains excessive moisture, hydraulic components will rust, oil emulsion deterioration, reduced lubricant film strength, speed mechanical wear and tear. Addition to maintenance to prevent moisture intrusion when, but also pay attention to oil tank whe
