我港口卡特980F型装载机动臂前端配装的工作装置用于抓取和倒运物料的夹具,通过该夹具的升降、开闭和翻转来抓取和倒运货物。本文介绍该型装载机工作装置液压系统工作原理及故障排查方法。1.工作原理工作泵16输出的压力油经过主溢流阀10调压后,进入动臂和翻转换向阀17以及夹持缸换向阀7。先导泵15输出的压力油经过先导溢流阀14调压后,进入动臂和翻转先导阀13以及夹持缸先导阀11。当操作人员操纵上述某个先
The working equipment fitted to the front of the boom of the Cattelline 980F loader at our port is used to grab and reload the jig of the material, and the cargo is grabbed and unloaded by lifting, opening and closing and flipping the jig. This article describes the working principle of this type of loader working device hydraulic system and troubleshooting methods. 1. Working principle The pressure oil output by the working pump 16 is regulated by the main relief valve 10 and enters the boom and the reversing directional valve 17 and the clamping cylinder reversing valve 7. The pressure oil output by the pilot pump 15 is regulated by the pilot relief valve 14 and then enters the boom and overturning pilot valve 13 and the pilot cylinder valve 11. When the operator manipulates one of the above
