摘  要

随着科技步伐的加快，液压技术在各个领域中得到了广泛应用，液压系统已成为主机设备中最关键的部分之一。但是，由于设计、制造、安装、使用和维护等方面的因素，影响了液压系统的正常运行。因此，了解系统工作原理，懂得一些设计、制造、安装、使用和维护等方面的知识，是保证液压系统能正常运行并极大发挥液压技术优势的先决条件。
本文主要研究的是液压传动系统，液压传动系统的设计需要与主机的总体设计同时进行。设计时，必须从实际情况出发，有机地结合各种传动形式，充分发挥液压传动的优点，力求设计出结构简单、工作可靠、成本低、效率高、操作简单、维修方便的液压传动系统。

Abstract

With the quickening pace of science and technology, hydraulic technology has been widely applied in various fields, the hydraulic system has become one of the most critical parts of a host device. However, due to factors of design, manufacturing, installation, use and maintenance etc, affect the normal operation of the hydraulic system. Therefore, to understand the working principle of the system, some understanding of design, manufacture, use and maintenance and other aspects of knowledge, is to ensure the normal operation of hydraulic system is a prerequisite of great use of hydraulic technology advantage.
This paper mainly studies the hydraulic drive system, the overall design and host of hydraulic transmission system at the same time. When the design, must proceed from actual conditions, combining various transmission forms, give full play to the advantages of hydraulic transmission, and strive to design hydraulic transmission system has the advantages of simple structure, reliable operation, low cost, high efficiency, simple operation, convenient repair.
