style="text-indent:25px">汽輪機(jī)圍帶的作用：增加葉片剛性，改變?nèi)~片的自振頻率，以避開(kāi)共振，從而提高了葉片的振動(dòng)安全性；減小汽流產(chǎn)生的彎應(yīng)力；可使葉片構(gòu)成封閉通道，并可裝置圍帶汽封，減小葉片頂部的漏氣損失。拉筋：拉筋的作用是增加葉片的剛性，以改善其振動(dòng)特性。但是拉筋增加了蒸汽流動(dòng)損失，同時(shí)拉筋還會(huì)削弱葉片的強(qiáng)度，因此在滿足了葉片振動(dòng)要求的情況下，應(yīng)盡量避免采用拉筋，有的長(zhǎng)葉片就設(shè)計(jì)成自由葉片。汽封轉(zhuǎn)子和靜體之間的間隙會(huì)導(dǎo)致漏汽，這不僅會(huì)降低機(jī)組效率，還會(huì)影響機(jī)組安全運(yùn)行。廣州大型汽輪機(jī)汽輪機(jī)汽缸內(nèi)安裝著噴嘴室、隔板、隔板套等零部件。</p><div

style="text-indent:25px">造成汽輪機(jī)進(jìn)水的因素有哪些？主要因素：油中進(jìn)水是油質(zhì)劣化的重要因素之一，油中進(jìn)水后，如果油中含有機(jī)酸，會(huì)形成油渣，還會(huì)使油系統(tǒng)發(fā)生腐蝕的危險(xiǎn)。油中進(jìn)水多半是汽輪機(jī)軸封的狀態(tài)不良或是發(fā)生磨損，軸封的進(jìn)汽過(guò)多所引起的。另外軸封汽回汽受阻，軸封高壓漏汽回汽不暢，軸承內(nèi)負(fù)壓太高等原因也往往直接構(gòu)成油中進(jìn)水。汽輪機(jī)的油中進(jìn)水是造成機(jī)器損壞的重要因素。解決：為防止油中進(jìn)水，除了在運(yùn)行中冷油器水側(cè)壓力應(yīng)低于油側(cè)壓力外，還應(yīng)精心調(diào)整各軸封的進(jìn)汽量，防止油中進(jìn)水。</p><p style="text-indent:25px">大功率汽輪機(jī)可以采用較高的蒸汽壓力和溫度，故熱效率較高。19世紀(jì)以來(lái)，汽輪機(jī)的發(fā)展就是在不斷提高安全可靠性、耐用性和保證運(yùn)行方便的基礎(chǔ)上，增大單機(jī)功率和提高裝置的熱經(jīng)濟(jì)性。發(fā)展前景：汽輪機(jī)的出現(xiàn)推動(dòng)了電力工業(yè)的發(fā)展，到20世紀(jì)初，電站汽輪機(jī)單機(jī)功率已達(dá)10兆瓦。隨著電力應(yīng)用的日益普遍，美國(guó)紐約等大城市的電站尖峰負(fù)荷在20年代已接近1000兆瓦，如果單機(jī)功率只有10兆瓦，則需要裝機(jī)近百臺(tái)，因此20年代時(shí)單機(jī)功率就已增大到60兆瓦，30年代初又出現(xiàn)了165兆瓦和208兆瓦的汽輪機(jī)?，F(xiàn)代汽輪機(jī)常用的聯(lián)軸器常用三種形式：剛性聯(lián)軸器，半撓性聯(lián)軸器和撓性聯(lián)軸器。</p><div
