能量流。基本液压回路中的动作顺序控制元件（二位四通换向阀）的换向和弹簧复位、执行元件（双作用液压缸）的伸出和回缩以及溢流阀的开启和关闭。对于执行元件和控制元件，演示文稿都是基于相应回路图符号，这也为介绍回路图符号作了准备。根据系统工作原理，您可对所有回路依次进行编号。如果第一个执行元件编号为0，则与其相关的控制元件标识符则为1。如果与执行元件伸出相对应的元件标识符为偶数，则与执行元件回缩相对应的元件标识符则为奇数。不仅应对液压回路进行编号，也应对实际设备进行编号，以便发现系统故障。DINISO12192标准定义了元件的编号组成，其包括下面四个部分设备编号、回路编号、元件标识符和元件编号。如果整个系统仅有一种设备，则可省略设备编号。实际中，另一种编号方式就是对液压系统中所有元件进行连续编号，此时，元件编号应该与元件列表中编号相一致。这种方法特别适用于复杂液压控制系统，每个9控制回路都与其系统编号相对应与机械传动、电气传动相比，液压传动具有以下优点1、液压传动的各种元件，可以根据需要方便、灵活地来布置。2、重量轻、体积小、运动惯性小、反应速度快。3、操纵控制方便，可实现大范围的无级调速（调速范围达20001）。4、可自动实现过载保护。5、一般采用矿物油作为工作介质，相对运动面可自行润滑，使用寿命长；6、很容易实现直线运动/7、很容易实现机器的自动化，当采用电液联合控制后，不仅可实现更高程度的自动控制过程，而且可以实现遥控。液压系统的缺点1、由于流体流动的阻力和泄露较大，所以效率较低。如果处理不当，泄露不仅污染场地，而且还可能引起火灾和爆炸事故。2、由于工作性能易受到温度变化的影响，因此不宜在很高或很低的温
