设计简介
摘要 用液体作为工作介质来实现能量传递的传动方式称为液压传动。液压系统是以电机提供动力基础，使用液压泵将机械能转化为压力，推动液压油。通过控制各种阀门改变液压油的流向，从而推动液压缸做出不同行程、不同方向的动作。完成各种设备不同的动作需要。液压系统已经在各个工业部门及农林牧渔等许多部门得到愈来愈广泛的应用，而且愈先进的设备，其应用液压系统的部分就愈多。所以像我们这样的大学生学习和亲手设计一个简单的液压系统是非常有意义的。
关键词：液压传动、稳定性、液压系统
Abstract Hydraulic system is powered motor basis, the use of hydraulic pump will translate into pressure on the mechanical energy, promote the hydraulic oil. Through various control valves to change the flow of hydraulic oil, thus promoting the hydraulic cylinders made of different itinerary, the movements in different directions. All kinds of different equipment to complete the actions required. Hydraulic system has been in various industrial sectors and agriculture, forestry, animal husbandry and fisheries, and many other departments are more widely used, and more advanced equipment, its application on the part of the hydraulic system more. So students like us to study and personally designed a simple hydraulic system is very meaningful.
