摘要
随着陆地上的矿产资源不断被开发利用,深海采矿的战略意义越来越重要。本文设计了一台用于模拟深海采矿的螺旋滚筒破碎试验台。其设计内容主要包括该设备的液压系统设计及其电气系统设计。液压系统设计主要有系统原理设计、元件选型、油路块的设计、液压泵站的设计以及实现该系统功能的电气控制系统设计。其中液压控制元件选择了叠加阀, 为了防止螺旋滚筒在切割工料时因矿石的凸凹不平产生倾斜,进而产生严重的偏载,本系统采用了双单向节流阀以达到液压缸的同步控制。电气控制系统采用较为简单的继电器控制,最后本文还合理设计了液压泵站。

ABSTRACT
Along with the exploitation of mining resource on the land, the stratagetic meaning of the deep-sea mining is ing more and more important. So I design a set of crash experimental bench with helical cutting dram .The experimental bench is used to simulate mining in deep sea. The content includes design of hydraulic system and electrical system of this experimental bench. The design of hydraulic system contains five parts. They are theoretical design of the system , selecting hydraulic elements, oil route block design , pumping station design and the electric controlling system design. The system selects superimposing valves as hydraulic control elements. In the cutting , the helical cutting drum will lean for the rugosity of the ore. The both-unilateralism throttles will solve the problem by in-phase control of the hydraulic cylinders. The electric controlling system selects relay control. At last, I design the hydraulic pumping station reasonablely.
