鉆、鏜兩用組合機(jī)床液壓系統(tǒng)的設(shè)計(jì)
摘要 液壓傳動(dòng)是以液壓油為工作介質(zhì),通過動(dòng)力元件將原動(dòng)機(jī)的機(jī)械能變?yōu)橐簤河偷膲毫δ埽偻ㄟ^控制元件,然后借助執(zhí)行元件將壓力能轉(zhuǎn)換成機(jī)械能,驅(qū)動(dòng)負(fù)載實(shí)現(xiàn)直線或回轉(zhuǎn)運(yùn)動(dòng)。液壓系統(tǒng)是液壓設(shè)備的重要組成部分,它與設(shè)備主體的關(guān)系密切,兩者的設(shè)計(jì)通常需要同時(shí)進(jìn)行。本次設(shè)計(jì)介紹了液壓系統(tǒng)的設(shè)計(jì)過程,具體講解了設(shè)計(jì)的步驟,分析了液壓系統(tǒng)的功能設(shè)計(jì)、需求分析所達(dá)到的目的,介紹總體設(shè)計(jì)方案的擬定方法、液壓系統(tǒng)原理圖的擬定過程、液壓元件的選擇方法及液壓系統(tǒng)性能驗(yàn)算方法。液壓系統(tǒng)設(shè)計(jì)原則是:深入調(diào)研,充分認(rèn)識(shí)設(shè)備應(yīng)具有的功能,從而分解出液壓系統(tǒng)的詳細(xì)設(shè)計(jì)需求;同時(shí)應(yīng)注意設(shè)備的特殊性,吸取國內(nèi)外先進(jìn)技術(shù),力求設(shè)計(jì)出的系統(tǒng)有質(zhì)量輕、體積小、效率高、結(jié)構(gòu)簡單等優(yōu)點(diǎn)。

Abstract Hydraulic system is an important part of hydraulic equipment, It with equipment subject closely, both the design usually need to simultaneously. Introduced the design of hydraulic systems design process, explain in detail the design steps, analyzes the functional design of hydraulic system, which achieved the goal of needs analysis, introduces the overall design scheme, the proposed method, the hydraulic system diagram formulating process, hydraulic components selection method, and hydraulic system performance calculating method. Hydraulic system design principle is: the in-depth research, fully realize the equipment should have the function of the hydraulic system, thereby decomposition of detailed design demand; And should also pay attention to the particularity of equipment, draw domestic and international advanced technology, and strive to design a system has light quality, small volume, high efficiency, simple structure, etc.
Key words Functional design hydraulic system diagram performance checked
