液压机系统故障70％以上是由液压介质(主要指液压油)引起的。除了介质受污染的原因外，液压油温过高也是影响液压机系统正常运行的重要原因之一250吨单柱液压机。液压机系统的正常工作温度为30—50℃单柱液压机，不高过70℃，不低于15℃。油温过高对液压机系统的性能有什么影响，造成油温过高的原因有哪些，怎么样预防呢？1. 液压机系统的构成及基本工作原理一个完整的液压机系统由以下部分组成：动力元件、执行元件、控制元件、辅助元件和液压油；动力元件(系统中的油泵)的作用是将电动机的机械能转换成液体的压力能，给整个液压机系统提供动力。执行元件(如液压缸和液压马达)的作用是将液体的压力能转换为机械能，驱动负载作直线往复运动或回转运动。控制元件(即各种液压阀)在液压机系统中控制和调节液体的压力、流量和方向。辅助元件包括油箱、滤油器、冷却器、加热器、压力表、油位油温计等。液压油是液压机系统中传递能量的工作介质拉伸液压机。
