单柱液压机液压系统设计
摘要
随着工业机械在国内飞速发展，现在液压传动技术已经发展得相当完善，由于单柱液压机具有结构简单，导向性好，噪声较小，污染少，工作稳定和易于成型等特点；逐渐成为工业机械中不可或缺设备。单柱液压机是一种以液体为工作介质，根据帕斯卡工作原理用于传递能量以实现各种工艺的机器。在农业机械、机械制造、汽车制造、锻压制造等等行业里面，都获得广泛应用。
由于液压系统是液压机核心部分，它性能好坏直接关系到整个液压机性能好坏。所以主要设计就是针对液压系统，其中对液压系统中液压缸设计及安装形式进行改善，还对液压阀，液压泵，活塞杆，缸盖等进行设计选型及强度校核，使其达到国家标准。设计后使单柱液压机液压系统达到操作简单目的，延长使用寿命液压冲击小，提高工作效率，有利于液压机向着全自动方向发展。通过设计对所学理论知识得到认知与运用，提高设计能力与经验。

Abstract
With the rapid development of industrial machinery in the country, now the hydraulic transmission technology has developed quite well, because of the single column hydraulic machine has a simple structure, good guidance, small noise, less pollution, stable work and easy to shape and so on, gradually become an indispensable equipment in industrial machinery. The single column hydraulic press is a kind of machine which takes liquid as the working medium and transmits energy according to the principle of Pascal to realize various processes. In agricultural machinery, machinery manufacturing, automotive manufacturing, forging and so on in the industry, have been widely used.
Because the hydraulic system is the core part of the hydraulic press, its performance is directly related to the performance of the hydraulic press. So the main design is for the hydraulic system, which the hydraulic system in the design and installation of hydraulic cylinder to improve the form of hydraulic valves, hydraulic pumps, piston rods, cylinder head and other design selection and strength check, so that it reached national standards. After design, the hydraulic system of single column hydraulic press achieves simple purpose, it can prolong the hydraulic impact of service life and improve working efficiency, which is beneficial to the development of hydraulic press. Through the design of the learned theoretical knowledge to gain recognition and application, improve the design ability and experience.
