采用液压传动的机械加工设备,为了完成预定的动作,又须以若干个元件按一定的路线联结起来,组成液压基本回路(以下简称“回路”)。液压系统(以下简称“系统”)则是几个回路依一定的序列组合起来的。这些回路互相配合完成主机的运动和动力要求。现在,我们简单地介绍几种常见的回路。 Using hydraulic transmission of mechanical processing equipment, in order to complete the scheduled action, but also to a number of components according to a certain route linked to form the basic hydraulic circuit (hereinafter referred to as the “loop”). The hydraulic system (hereinafter referred to as the “system”) is a combination of several circuits that follow a certain sequence. These circuits cooperate with each other to complete the host’s motion and power requirements. Now, let’s briefly introduce several common loops.
