【正文】 大于 200m，故采用梳齒式止漏環(huán)，機(jī)械裝配點(diǎn)焊與轉(zhuǎn)輪固定，根據(jù)《水輪機(jī)設(shè)計(jì)手冊(cè)》表 1011，由轉(zhuǎn)輪直徑查選梳齒密封間隙為 . 泄水錐泄水錐形式參照典型結(jié)構(gòu)，與上冠的連接方式采用 16 個(gè)布置在連軸螺釘內(nèi)側(cè)的 M60 螺釘把合，為避免運(yùn)行中脫落，另與上冠點(diǎn)焊加強(qiáng)，材料為 Z5CN1704M。后者在小型機(jī)組中應(yīng)用較廣，但由于本設(shè)計(jì)為大型機(jī)組，故采用法蘭螺釘連接的方式，轉(zhuǎn)輪重量由發(fā)電機(jī)推力軸承承擔(dān)，轉(zhuǎn)輪法蘭尺寸符號(hào)及數(shù)值如圖 2表 222 所示。 圖 21 流道圖表 21 流道尺寸參數(shù)符號(hào) 數(shù)值（mm） 參數(shù)符號(hào) 數(shù)值（mm）D0 4743 R1 3636D1 4158 R2 995D2 1810 R3 60Dk 1175 h1 1664bo h2 1075 轉(zhuǎn)輪部分 轉(zhuǎn)輪結(jié)構(gòu)：福建仙游蓄能電站水泵水輪機(jī)結(jié)構(gòu)設(shè)計(jì)4轉(zhuǎn)輪是水輪機(jī)中直接將水能轉(zhuǎn)換為機(jī)械能的部件，由于不受運(yùn)輸條件的限制(?3886mm)，所以轉(zhuǎn)輪采用整體鑄造，轉(zhuǎn)輪由上冠、下環(huán)、7 個(gè)葉片和泄水錐等組成，材料為 Z5CN1704M。高水頭水泵水輪機(jī)的軸面流道十分扁平，進(jìn)口直徑D1 與出口直徑 D2 的比率一般為 2：1 或更大，相對(duì)導(dǎo)葉高度 b0 不超過(guò) 10%。：福建仙游蓄能電站水泵水輪機(jī)結(jié)構(gòu)設(shè)計(jì)2 設(shè)計(jì)內(nèi)容（一）根據(jù)給定的福建仙游蓄能電站基本資料進(jìn)行水輪機(jī)總體結(jié)構(gòu)設(shè)計(jì) ，確定水輪機(jī)的主要特征尺寸，對(duì)水輪機(jī)主要部件進(jìn)行結(jié)構(gòu)設(shè)計(jì)； ； 。通過(guò)本次畢業(yè)設(shè)計(jì)，進(jìn)一步提高自己的動(dòng)手和創(chuàng)新能力，深入了解常規(guī)水輪機(jī)及水泵水輪機(jī)的結(jié)構(gòu)，拓寬視野，為自己即將到來(lái)的研究生學(xué)習(xí)奠定良好的基礎(chǔ)。既可以將平時(shí)的專業(yè)理論知識(shí)進(jìn)行系統(tǒng)的實(shí)踐練習(xí)，又能通過(guò)各種中外文文獻(xiàn)的學(xué)習(xí)，了解專業(yè)領(lǐng)域最新的研究方向。本次畢業(yè)設(shè)計(jì)通過(guò)查閱各種參考文獻(xiàn)和水輪機(jī)設(shè)計(jì)手冊(cè)，在掌握常規(guī)水輪機(jī)機(jī)組結(jié)構(gòu)的前提下，學(xué)習(xí)水泵水輪機(jī)的結(jié)構(gòu)特點(diǎn)。水泵水輪機(jī)作為蓄能電站的核心設(shè)備，其機(jī)構(gòu)設(shè)計(jì)的合理性直接影響到運(yùn)行效率、運(yùn)行穩(wěn)定性等諸多方面，因此合理的結(jié)構(gòu)設(shè)計(jì)是保障電站經(jīng)濟(jì)運(yùn)行的首要前提。抽水蓄能電站作為目前解決盈余電能儲(chǔ)存問(wèn)題的最有效方式，其調(diào)峰填谷、調(diào)頻調(diào)相、旋轉(zhuǎn)備用的作用日益突出，對(duì)于提高電網(wǎng)穩(wěn)定性和供電質(zhì)量意義重大。關(guān)鍵詞：福建仙游蓄能電站, 水泵水輪機(jī), 結(jié)構(gòu)設(shè)計(jì),CAD2022 屆熱能與動(dòng)力工程專業(yè)畢業(yè)設(shè)計(jì)（論文） The Structural Design of Pumpturbine inFujian Xianyou Pumped Storage Power stationAbstract Pumped storage power station plays a pivotal role in pekaclipping of power grid，being significant to improve the quality of power supply and the flexibility of power ，which is specially applied to pumped storage power station，transfers between turbine and pump according to the manage of power grid to fulfil the vital task of peak regulation and frequency adjustment. 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(jī)結(jié)構(gòu)設(shè)計(jì)目錄1．前 言 .......................................................1 概述 ....................................................1 設(shè)計(jì)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(jì)算 .......................................6 主軸結(jié)構(gòu)設(shè)計(jì) .......................................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(dòng)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
