style="text-indent:25px">汽輪機(jī)通常在高溫高壓及高轉(zhuǎn)速的條件下工作，是一種較為精密的重型機(jī)械，一般須與鍋爐（或其他蒸汽發(fā)生器）、發(fā)電機(jī)（或其他被驅(qū)動(dòng)機(jī)械）以及凝汽器、加熱器、泵等組成成套設(shè)備，一起協(xié)調(diào)配合工作。結(jié)構(gòu)部件：由轉(zhuǎn)動(dòng)部分和靜止部分兩個(gè)方面組成。轉(zhuǎn)子包括主軸、葉輪、動(dòng)葉片和聯(lián)軸器等。靜子包括進(jìn)汽部分、汽缸、隔板和靜葉柵、汽封及軸承等。汽缸是汽輪機(jī)的外殼，其作用是將汽輪機(jī)的通流部分與大氣隔開，形成封閉的汽室，保證蒸汽在汽輪機(jī)內(nèi)部完成能量的轉(zhuǎn)換過程，汽缸內(nèi)安裝著噴嘴室、隔板、隔板套等零部件。汽輪機(jī)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。山西汽輪機(jī)配套廠家</p><p style="text-indent:25px">供熱式汽輪機(jī)既提供動(dòng)力驅(qū)動(dòng)發(fā)電機(jī)或其他機(jī)械，又提供生產(chǎn)或生活用熱。福建汽輪機(jī)有多少級</p><p style="text-indent:25px">背壓式汽輪機(jī)的排汽壓力高，蒸汽的焓降較小，與排汽壓力很低的凝汽式汽輪機(jī)相比，發(fā)出同樣的功率，所需蒸汽量為大，因而背壓式汽輪機(jī)每單位功率所需的蒸汽量大于凝汽式汽輪機(jī)。但是，背壓式汽輪機(jī)排汽所含的熱量絕大部分被熱用戶所利用，不存在冷源損失，所以從燃料的熱利用系數(shù)來看，背壓式汽輪機(jī)裝置的熱效率較凝汽式汽輪機(jī)為高。由于背壓式汽輪機(jī)可通過較大的蒸汽流量，前幾級可采用尺寸較大的葉片，所以內(nèi)效率較凝汽式汽輪機(jī)的高壓部分為高。在結(jié)構(gòu)上，背壓式汽輪機(jī)與凝汽式汽輪機(jī)的高壓部分相似。福建汽輪機(jī)有多少級</p><p
