style="text-indent:25px">汽輪機(jī)檢修加工會遇到哪些難題呢?平時廠家在針對汽輪機(jī)內(nèi)部結(jié)構(gòu)“口小肚子大”、加工空間小且軸承檔內(nèi)各尺寸精度要求高的問題：工件結(jié)構(gòu)，汽輪機(jī)為我公司設(shè)計的一款汽輪機(jī)，此臺汽輪機(jī)前汽缸為鑄件，前汽缸與前軸承座是通過下半的半圓坡口焊接連接，并且該工件總長有2m，內(nèi)徑小處*有φ 235mm，加工空間很小，而且軸承座各檔內(nèi)圓的尺寸精度要求很高，對于加工及檢驗(yàn)測量是一個很大的挑戰(zhàn)。加工難點(diǎn)分析，在圖樣的消化過程中，我們發(fā)現(xiàn)了在汽輪機(jī)加工時可能出現(xiàn)的問題與難點(diǎn)如下：前汽缸與前軸承座通過下半的半圓坡口焊接連接，如何保障焊接精度？如何控制焊接變形量？前汽缸與前軸承座焊接完后整體工件長度有2m，其中前汽封小內(nèi)圓只有φ235mm，而軸承檔部分要將車刀穿過小內(nèi)圓來加工，軸承檔大內(nèi)圓為φ359mm，造成了“口小肚子大”的情況，而且軸承檔內(nèi)各尺寸精度要求很高，公差小處*為0.03mm。</p><p style="text-indent:25px">汽輪機(jī)也稱蒸汽透平發(fā)動機(jī)，是一種旋轉(zhuǎn)式蒸汽動力裝置，高溫高壓蒸汽穿過固定噴嘴成為加速的氣流后噴射到葉片上，使裝有葉片排的轉(zhuǎn)子旋轉(zhuǎn)，同時對外做功。汽輪機(jī)是現(xiàn)代火力發(fā)電廠的主要設(shè)備，也用于冶金工業(yè)、化學(xué)工業(yè)、艦船動力裝置中。汽輪機(jī)按照工作原理分為沖動式汽輪機(jī)和反動式汽輪機(jī)。汽輪機(jī)是一種以蒸汽為動力，并將蒸氣的熱能轉(zhuǎn)化為機(jī)械功的旋轉(zhuǎn)機(jī)械，是現(xiàn)代火力發(fā)電廠中應(yīng)用很普遍的原動機(jī)。汽輪機(jī)具有單機(jī)功率大、效率高、壽命長等優(yōu)點(diǎn)。按汽缸數(shù)目：可分為單缸汽輪機(jī)、雙缸汽輪機(jī)和多缸汽輪機(jī)。</p><div
