It also shows unique features in structure due to the characteristics of high water head, high speed, large capacity, plex operation condition and frequent startstop. Fujian Xianyou pumped storage power station is extremely typical when it es to the scale，unit capacity,or the highhead pump graduation project takes Guangzhou pumped storage power station as the object,aiming at pleting the structural design of Francis pumpturbine in this power station by refering to related data,the design hand book of hydraulic turbine and Computer Aided Design overall assembly, the distributor assembly, as well as some of the major parts are well designed.KEY WORDS: Fujian Xianyou pumped storage power station, pumpturbine, structural design, CAD：福建仙游蓄能電站水泵水輪機結(jié)構(gòu)設(shè)計目錄1．前 言 .......................................................1 概述 ....................................................1 設(shè)計內(nèi)容 ................................................2 原始資料 ................................................2 .......................................3 繪制軸面流道圖 ..........................................3 轉(zhuǎn)輪部分 ................................................3 轉(zhuǎn)輪結(jié)構(gòu) ...........................................3 轉(zhuǎn)輪連接 ..........................................4 轉(zhuǎn)輪止漏裝置 .......................................5 泄水錐 .............................................5 轉(zhuǎn)輪減壓裝置 ......................................5 .........................................6 主軸直徑計算 .......................................6 主軸結(jié)構(gòu)設(shè)計 .......................................7 水導(dǎo)軸承 ...........................................9 主軸密封 ..........................................10 檢修密封 ..........................................12 座環(huán) ...................................................14 頂蓋 ...................................................15 底環(huán) ...................................................16 基礎(chǔ)環(huán) .................................................17 蝸殼 ...................................................17 接力器 .................................................18 真空破壞閥 .............................................18 ....................................................19 活動導(dǎo)葉翼型 ...........................................20 導(dǎo)葉開度的確定 .........................................21 導(dǎo)葉結(jié)構(gòu)、尺寸和軸頸選擇 ...............................21 導(dǎo)葉的密封結(jié)構(gòu) .........................................23 導(dǎo)葉套筒 ...............................................23 導(dǎo)葉止推裝置 ...........................................24 導(dǎo)葉軸頸密封 ...........................................25 導(dǎo)葉軸套 ...............................................26 ........................................28 導(dǎo)葉臂 .................................................29 連接板 .................................................30 叉頭 ...................................................31 連接螺桿 ...............................................32 端蓋 ...................................................32 分半鍵 .................................................33 剪斷銷 .................................................34 叉頭銷 ...
