【正文】 謝 辭 經(jīng)過幾個月的不懈奮斗，畢業(yè)設(shè)計幾乎要圓滿結(jié)束 。在油箱的底部我們設(shè)計了斜面，也就是有一定的傾斜度，方便對沉淀物處理。松開按鈕即停止。當(dāng)按下按鈕啟動時，電機 M 啟動，從而帶動液壓泵轉(zhuǎn)動，接著將油箱中的液壓油輸送到管路中，閥門打開，油回到油箱進而實現(xiàn)空載啟動。執(zhí)行元件是滑塊、主油缸、頂出缸。傳統(tǒng)的壓力機很少有能在自身速度和壓力范圍內(nèi)無級可調(diào)的，這樣有時候會很難是 其達到精準(zhǔn)要求；但液壓機圓滿解決了這個問題。s guide and a few years of data on the book, which could lead to the design process is not particularly rigorous calculation is not perfect, but it is the efforts of results. Through the joint efforts of the teachers and I have the following findings: First, through the material mechanics and theoretical mechanics choose to calculate reasonable YH32500 hydraulic machine of structural parameters, the main part (master cylinder and the top of the cylinder) and other strength check, plete assembly drawing and parts drawings. Second, the design by hydrodynamics knowledge YH32500 hydraulic machine hydraulic schematic diagram, select the calculation reasonably high and low pressure pumps, high and low pressure vessel (tank, filling boxes, etc.), various valves and the corresponding connecting pipes. Third, through the threedimensional software for YH32500 hydraulic machine main parts (the master cylinder and the top of the cylinder) and other structural analysis. Fourth, the college summarize knowledge and application, foster innovation.

This is the development and improvement of the hydraulic machine has a certain role in promoting. However, due to relatively small current publication about the hydraulic system design reference, so we pass the teacher39。對本文的研究做出重要貢獻的個人和集體，均已在文中以明確方式標(biāo)明。本人授權(quán) 大學(xué)可以將本學(xué)位論文的全部或部分內(nèi)容編入有關(guān)數(shù)據(jù)庫進行檢索，可以采用影印、縮印或掃描等復(fù)制手段保存和匯編本學(xué)位論文。 system 目錄 第一章 前言 .................................................................................................................... 3 .............................................................................................. 3 液壓機的型號介紹及控制順序分析 ..................................................................... 4 ........................................................................................... 4 第二章 YH32315 通用液壓機的總體設(shè)計 ......................................................................... 5 ........................................................................................... 5 YH32315液壓機各部分的方案選擇 .................................................................... 6 YH32315總體布局設(shè)計 ...................................................................................... 7 第三章 YH32315液壓機液壓系統(tǒng)設(shè)計 ............................................................................. 7 ..................................................................................................... 7 .............................................................................................. 8 ....................................................................................... 8 ............................................................................................ 10 第四章 YH32315 液壓系統(tǒng)中各元件的確定 .................................................................... 12 ................................................................................................ 12 ............................................................................................ 12 D ...................................................................................... 12 ......................................................................................... 13 .................................................................................. 13 .................................................................................. 15 ......................................................... 15 .............
