汽车驾驶员喜欢在建造良好,铺面平坦的道路上行驶。然而,建造一条有光滑沥青路面的好路,是一件相当复杂的工作,除了熟练工人之外,技术先进的机械在摊铺路面时工作可靠,必要时它们还应能充填路面上的坑洼,以提供一平坦路面。现代的液压控制和执行方法,已能满足这些要求。巴伯—格林公司生产的 SA—125型沥青混凝土摊铺机上的各种液压系统,是这些机械运行中的最重要和关键的部分。该机的液压系统经常在恶劣的环境中运行,当处理已予热到110℃以上的石油基产品时,环境温度很高。
Motorists like to drive on well-built, flat roads. However, the construction of a good road with a smooth asphalt surface is a rather complicated task. In addition to skilled workers, technologically advanced machinery works reliably when paving the road. If necessary, they should also be able to fill the pits on the road surface. To provide a flat surface. Modern hydraulic control and execution methods have met these requirements. The various hydraulic systems on the SA-125 asphalt concrete pavers produced by Barbour-Green are the most important and critical part of these mechanical operations. The hydraulic system of the aircraft is often operated in harsh environments. When dealing with petroleum-based products that have been preheated above 110°C, the ambient temperature is high.
