毕业设计-小型液压压力机液压系统设计――（液压缸），说明书共37页，21018字，附设计图纸。
[摘 要]液压传动，又称液压技术，使机械设备中发展速度最快的技术之一，特别是近年来，随着机电一体化技术的发展，与微电子、计算机技术相结合，液压传动进入了一个新的发展阶段。本文以机械与液压传动知识的基础，对小型液压机的设计原理进行了详尽的介绍，其中重点介绍了该系统极其执行元件液压缸的设计过程，本系统的要求就是满足普通用户的使用要求，使之更加经济的来加工工件。在此系统中，首先进行液压系统基本工作压力的确定，选定合适的工作压力，从而计算出执行元件的一些基本尺寸，液压系统的基本参数，确定出合适的系统，设计出系统原理图，根据原理图选择液压阀类元件，在手册中找出它们的一些参数，并根据这些参数进行系统验算。

The Ddsign Of Minntype Hydraulic Pressrue(Hydraulic Cylinder)
AbstractOn the base of an analysis of the project given,the main work,which designs compact hydraulics pressure system , is that the system can work in the whole working circle including quick blank line , slow pressing , quick returning and stopping . Then according to the demanding , we can calculate the data by given , check and adjust in order to establish the hydraulics pressure . According to the requirement of the hydraulics system working , we can design a pumping station . It request us to regard the theonries that we have leamed as the foundation , such as the postulate of hydraulic power , the structure of hydraulic elements , the prunciple of operation and the fundamental circuit (including typical tool’ hydraulics) etc . Otherwise , we should pay attention to investigations and utilize predecessor’ experience .

With the development of the society, great changes have taken place in the realm of machine elements,changing fron the jumbo to the mini-type ,its not suitable to process mini-type accessories with large-scale hydraulic plants,so, I haue a design of this equipment to come meet of thede conditions when the belocity di not high and the pewssure is not grsat .
