中文题目：钻床液压系统的设计
外文题目：DRILING MACHINE HYDRAULIC SYSTEM DESIGN
摘要
本设计在分析了钻床技术要求的基础上,根据立式钻床的特点和要求，进行它的液压系统设计，重点介绍这种钻床的液压系统工作原理、液压系统的设计、阀块块设计和油箱及液压泵站的设计。该液压系统性能良好,工作稳定。
本次设计的题目是钻床液压系统的设计,设计时考虑的功能比较齐全。由于本系统的压力小(3MPa),流量小,普通的滑阀就能满足其要求。
钻床液压泵站是近年来发展起来的设备，自动化程度较高。本文先对钻床液压系统的要求进行了阐述，并对设计要求和设计步骤进行了说明。主要是对阀，泵，马达和缸的选取，油箱，阀块及阀组的设计，系统的性能较核与验算为主。并且对本液压系统的保养与维护有着详细的说明和要求。
近30年来，由于原子能技术、航空航天技术、控制技术、材料科学、微电子技术等学科的发展，再次将液压技术推向前进，使它发展成为包括传动、控制、检测在内的一门完整的自动化技术，在国民经济的各个部门都得到了应用，如工程机械、数控加工中心、冶金自动线等。采用液压传动的程度已成为衡量一个国家工业水平的重要标志之一。

Abstract
The design of the analysis of the drilling machine technology request, based on the characteristics ofvertical drilling and requirements for the hydraulic system design,which focuses on the drilling hydraulic system principle, hydraulic system design, Valve design and horizontal tank and pump station design. The hydraulic system is in good, stable jobs.
The Design graduate Rocker is the subject of drilling machine hydraulic system design, design considerations of the function of a relatively complete. Due to the pressure of the system is small(C306), flow of small, ordinary slidevalvewill be able to meet its requirements.
Drilling hydraulic station is developed in recentyears for equipment, a higher degree of automation. The article focuses on the drilling hydraulic system to the requirements of the paper, the design requirements and design steps described. The mainvalve, pump, motor and cylinder selection, tanks,valves andvalve block to the block design, the performance of the system than nuclear and mainly checking. And the right hydraulic system maintenance and maintenance is a detailed description and requirements.
Nearly 30years, as a result of nuclear energy technology, aerospace technology, control technology, material science, microelectronics technology disciplines, such as the development of hydraulic technologywill once again push forward into it, including transmission, control, Detection of a complete automation technology, in every sector of the national economy have been applied, such as engineering machinery, CNC Machining Center, metallurgical automatic lanes. Hydraulic Drive has become a national industrial measuring the level of one of the important signs.
