Hydraulic & Lubrication 油压 液压 润滑

The word "Hydraulics" originates from the Greek word ὑδραυλικός (hydraulikos) which in turn originates from ὕδωρ (hydor, Greek for water) and αὐλός (aulos, meaning pipe).

Lubricating oils are commonly used to reduce friction and wear and optimize the life of PT components such as bearings and gears. … In such applications, oil lubrication can wash the contaminants away from the bearings. Lubricating oils also serve as heat transfer fluids.

机械式的液压动力转向系统一般由液压泵油管、压力流量控制阀体、V型传动皮带、储油罐等部件构成。它诞生于1902年,也就是说已经有了百年历史。由于技术成熟可靠,而且成本低廉,得以被广泛普及。

机床润滑包括轴承齿轮导轨和顶尖的润滑;机床润滑油脂包括:液压油、液压导轨油和润滑油(脂),不同的机床种类及工况的不同对润滑油品的性能有不同的要求。
