Especially in recent years, but with microelectronics, computer technology to combine together, make hydraulic technology has entered a new stage of development. At present, has been widely used in the industrial fields. Because the recent years microelectronics, the development of computer technology, hydraulic components manufacturing technology of the further improved, and make hydraulic technology not only as a kind of basic in traditional form occupies an important position and with excellent static, dynamic performance becomes a kind of important means of control.Facing our country economy in recent years of rapid development, machinery manufacturing industry in the development of the national economy, which occupies an important position in the manufacturing sector to the healthy and rapid development. The improvement of manufacturing equipment, make as an important equipment manufacturing industry in the of all kinds of machining equipment also had many new changes, especially in the hole processing, its in todays hydraulic system is becoming more and more important.The hydraulic system design, in addition to meet the host in action and performance requirements outside, still must comply with small volume, light weight, low cost, high efficiency, simple structure, reliable operation, use and convenient maintenance and so on some of the common design principles recognized. Hydraulic system is designed according to the known condition, to determine the hydraulic pressure working scheme, hydraulic flow rate, pressure and hydraulic pump and other components of the design. To sum up, complete the whole design process needs a series of hard work. Designers should set up the correct design thought, trying hard to grasp the advanced scientific and technological knowledge and scientific dialectical way of thinking. to the workers engaged in production practice and workers learning, and constantly development and innovation, to better complete mechanical design task.Key words: Hydraulic system hydraulic cylinder hydraulic pump reversing valves目 录引 言.2第一章 液压系统设计计算 21.1 液压系统的设计要求21.2 液压系统方案设计21.2.1 确定液压泵类型及调速方式21.2.2 选用执行原件21.2.3 换向回路和压力回路的选择21.2.4 组成液压系统绘原理图21.3 液压系统的参数计算21.3.1 液压缸参数计算21.3.2 液压缸的结构设计21.3.3 液压泵性能参数计算21.4 液压元件的选择21.4.1 液压阀及过滤器的选择21.4.2 油管的选择21.4.3 油箱容积的确定2第二章 液压站的设计22.1 液压油箱的作用及外形尺寸22.1.1 液压油箱的作用22.1.2 液压油箱的外形尺寸22.2 液压油箱的结构设计22.3 液压泵装置22.3.1 液压泵的工作原理22.3.2 液压控制装置22.4 液压系统的安装22.4.1 液压泵装置的安装要求22.4.2 油箱装置的安装要求22.4.3 液压阀的安装要求22.4.4 液压缸的安装要求22.5 电动机与液压泵的联接方式2第三章 集成块的设计 23.1 集成块及其工作23.2 集成块的工作要求23.2.1 集成块的工作要求23.2.3 集成块的总体设计23.2.4 液压阀位置的确定23.2.5 视图及尺寸标注23.2.6 加工精度的要求23.2.7 集成块的设计结果23.2.8 集成块装配与调试2第四章 液压系统的性能验算及维护24.1 性能验算24.1.1 沿程压力损失24.1.2 局部压力损失24.1.2 系统温升的验算24.1.3 泵站调试24.1.4 压力调试
