【正文】 摘 要 面對(duì)我國(guó)經(jīng)濟(jì)近年來(lái)的快速發(fā)展，機(jī)械制造工業(yè)的壯大，在國(guó)民經(jīng)濟(jì)中占重要地位的制重 造業(yè)領(lǐng)域得以健康快速的發(fā)展。制造裝備的改進(jìn)，使得作為制造工業(yè)重要設(shè)備的各類(lèi)機(jī)加工藝裝備也有了許多新的變化，尤其是孔加工，其在今天的液壓系統(tǒng)的地位越來(lái)越重要。 鏜床液壓系統(tǒng)的設(shè)計(jì)，除了滿(mǎn)足主機(jī)在動(dòng)作和性能方面規(guī)定的要求外，還必須符合體積小、量輕、成本低、效率高、結(jié)構(gòu)簡(jiǎn)單、工作可靠、使用和維修方便等一些公認(rèn)的普遍設(shè)計(jì)原則。液壓系統(tǒng)的設(shè)計(jì)主要是根據(jù)已知的條件，來(lái)確定液壓工作方案、液壓流量、壓力和液壓泵及其它元件的設(shè)計(jì)。 綜上所述 ，完成整個(gè)設(shè)計(jì)過(guò)程需要進(jìn)行一系列艱巨的工作。設(shè)計(jì)者首先應(yīng)樹(shù)立正確的設(shè)計(jì)思想，努力掌握先進(jìn)的科學(xué)技術(shù)知識(shí)和科學(xué)的辯證的思想方法。同時(shí)，還要堅(jiān)持理論聯(lián)系實(shí)際，并在實(shí)踐中不斷總結(jié)和積累設(shè)計(jì)經(jīng)驗(yàn)，向有關(guān)領(lǐng)域的科技工作者和從事生產(chǎn)實(shí)踐的工作者學(xué)習(xí)，不斷發(fā)展和創(chuàng)新，才能較好地完成機(jī)械設(shè)計(jì)任務(wù)。 關(guān)鍵詞： 液壓缸 ； 液壓泵 ； 換向閥Abstract Faced with China39。s rapid economic development in recent years, mechanical manufacturing industry growth, play a significant role in the national economy was healthy and rapid development of the field of heavy industry. Improvement of the manufacturing equipment, making various types of machining process as an important equipment manufacturing industry equipment has many new changes, especially the hole, it is being more and more important in today39。s hydraulic system. Hydraulic system design of boring machine, in addition to meeting the host provided for in action and performance requirements, must also ply with the small volume, light weight, low cost, high efficiency, simple structure, reliable working, convenient operation and maintenance, and other generally recognized principles of universal design. Design of the hydraulic system is based mainly on a known condition, programme of work to determine the hydraulic, hydraulic pumps and hydraulic flow, pressure, and other elements of design. To sum up, a series of hard work through the design process needed. Designers should first establish a correct design, efforts to acquire advanced knowledge of science and technology and science of dialectical thinking method. At the same time, we must persist in integrating theory with practice, and constantly sum up and design experience accumulated in the practice, to the fields of science and technology workers and workers engaged in the production, continuous development and innovation in order to better plete mechanical design tasks.
