style="text-indent:25px">汽輪機(jī)按照蒸汽參數(shù)（壓力和溫度）分為：低壓汽輪機(jī)：主蒸汽壓力小于1.47Mpa；中壓汽輪機(jī)：主蒸汽壓力在1.96—3.92Mpa；高壓汽輪機(jī)：主蒸汽壓力在5.88—9.8Mpa；超高壓汽輪機(jī)：主蒸汽壓力在11.77—13.93Mpa；亞臨界壓力汽輪機(jī)：主蒸汽壓力在15.69—17.65Mpa；超臨界壓力汽輪機(jī)：主蒸汽壓力大于22.15Mpa；超超臨界壓力汽輪機(jī)：主蒸汽壓力大于32Mpa；由于冶金技術(shù)的不斷發(fā)展，使得汽輪機(jī)結(jié)構(gòu)也有了很大改進(jìn)。大機(jī)組普遍采用了高中壓合缸的雙層結(jié)構(gòu)，高中壓轉(zhuǎn)子采用一根轉(zhuǎn)子結(jié)構(gòu)，高、中、低壓轉(zhuǎn)子全部采用整鍛結(jié)構(gòu)，軸承較多地采用了可傾瓦結(jié)構(gòu)。</p><p style="text-indent:25px">汽輪機(jī)氣缸變形的原因與汽缸壁及法蘭金屬的厚度和結(jié)構(gòu)尺寸有關(guān)，與啟停工況時(shí)投入法蘭、螺栓加熱的操作有關(guān)，與汽缸保溫情況也有一定的關(guān)系，還與制造過(guò)程有關(guān)。由于汽缸鑄造時(shí)的時(shí)效問(wèn)題，以及復(fù)雜的受力情況，汽缸變形是不可避免的問(wèn)題，通常會(huì)表現(xiàn)為汽缸出現(xiàn)內(nèi)張口或外張口的情況，而且低壓缸更容易出現(xiàn)這個(gè)問(wèn)題。出現(xiàn)此問(wèn)題后，應(yīng)避免采用開(kāi)槽等破壞性的修復(fù)手法，西方國(guó)家應(yīng)用比較成熟的技術(shù)是采用德國(guó)西門子能源事業(yè)部采用的高溫平面密封劑修復(fù)技術(shù)對(duì)變形的結(jié)合面間隙進(jìn)行直接修復(fù)。汽輪機(jī)是現(xiàn)代火力發(fā)電廠的主要設(shè)備。</p><div
