中压旨在向作业机具提供用于机具旋转的油。 附件阀用于控制油流。 此阀通过比例减压阀移动,允许操作员通过机具旋转完成电子控制。 辅助泵用于提供中压油流。 使用中压的作业机具典型示例是液压剪或者抓斗。

参考: 请参阅机具控制系统的测试和调整, "作业机具参数 - 编程",以更改作业机具操作设置。

参考: 请参阅机具控制系统的测试和调整, "中压:作业机具参数的默认值",以参考出厂设定值。

当启用装置在伸出位置操作时,比例减压阀 (6) 接收来自机器 ECM 的调制信号。 比例减压阀 (6) 允许先导油流向附件控制阀 (4)。 这将移动附件控制阀 (4),使中压油从辅助泵 (12) 流向液压旋转马达 (2)。

来自旋转马达的回油经附件控制阀 (4)、机油冷却器,流回液压油箱。

旋转工作压力受到中压回路安全阀 (5) 的限制。
