水基液压系统Water-based hydraulic systems

中文译文
水基液压系统Water-based hydraulic systems(中文2600字,英文1700字)
    传统上水基液压系统已经应用在钢铁厂炼铁领域。 这些产业中水基液压系统的明显的优点是它们的耐火性。 而且水基液压系统在费用上也优于油基的液压系统。 首先，无毒的、可被生物分解的综合性添加剂每加仑花费5到6美元。一加仑集中可生成20加仑的5%溶液，因此实际上水基液压流体的费用可以比油基的每加仑少30分。
在工厂的水平下，考虑到相关费用、防止和清理环境的污染，水基液压系统拥有节省巨大成本的潜力。液压油的泄漏已经成为一个非常重要的问题。它必须被收集、妥善控制。不过，含有合成添加剂的水，可以倾倒入工厂的污水系统。' j, L, ~( D2 b9 O( l* `
在工厂水平下，节省成本不停留在流体的较低成本及其处理上。因为水基液压液由十部分水和一部份合成添加剂， 5加仑添加剂与水的混合物构成100加仑水基流体。 50加仑的容器当然比两个55加仑的桶更容易处理，因此储藏更简单、更清洁、更不凌乱，运输成本也较低。. J0 _7 ]2 i: Z# a

英文原文 
 Water-based hydraulic systems
    Water-based hydraulic systems traditionally have been used in hot-metal areas of steel mills. The obvious advantage of water systems in these industries is their fire resistance. Water-based hydraulic systems also have obvious cost advantages over oil-based fluid. First, non-toxic, biodegradable synthetic additives for water cost $5 to $6 per gallon. One gallon of concentrate can make 20 gallons of a 5% solution, so the cost of water-based hydraulic fluid actually can be less than 30 cents per gallon.
    Considering the costs associated with preventing and cleaning up environmental contamination, water-based hydraulic systems hold the potential for tremendous cost savings at the plant level. Oil that has leaked already becomes a very important problem. It must be collected, properly contained. Water containing synthetic additives, however, can by dumped into plant effluent systems.
