style="text-indent:25px">汽輪機(jī)汽封按安裝位置的不同，分為通流部分汽封、隔板汽封、軸端汽封。軸承是汽輪機(jī)一個(gè)重要的組成部分，分為徑向支撐軸承和推力軸承兩種類(lèi)型，它們用來(lái)承受轉(zhuǎn)子的全部重力并且確定轉(zhuǎn)子在汽缸中的正確位置。多油楔軸承（三油楔、四油楔）：輕載、耗功大，高速小機(jī)，圓軸承：可承重載，瓦溫高，橢圓軸承：可承重載，可傾瓦軸承：2、4、5、6瓦塊軸承，穩(wěn)定性好，承載范圍大，耗油量較大，推力軸承：1）固定瓦塊式：承載能力小，用于小機(jī)組。2）可傾瓦塊式：①密切爾式：瓦塊背面線接觸；②金斯伯里式：瓦塊背面點(diǎn)接觸。優(yōu)點(diǎn)：與往復(fù)式蒸汽機(jī)相比，汽輪機(jī)中的蒸汽流動(dòng)是連續(xù)的、高速的，單位面積中能通過(guò)的流量大，因而能發(fā)出較大的功率。抽汽式汽輪機(jī)是能從中間級(jí)抽出蒸汽供熱的汽輪機(jī)。北京汽輪機(jī)檢修平臺(tái)</p><p style="text-indent:25px">凝汽式汽輪機(jī)排出的蒸汽流入凝汽器，排汽壓力低于大氣壓力，因此具有良好的熱力性能。北京汽輪機(jī)檢修平臺(tái)</p><p style="text-indent:25px">背壓式汽輪機(jī)的排汽壓力大于大氣壓力的汽輪機(jī)；抽汽式汽輪機(jī)是能從中間級(jí)抽出蒸汽供熱的汽輪機(jī)；飽和蒸汽輪機(jī)是以飽和狀態(tài)的蒸汽作為新蒸汽的汽輪機(jī)。汽輪機(jī)的蒸汽從進(jìn)口膨脹到出口，單位質(zhì)量蒸汽的容積增大幾百倍，甚至上千倍，因此各級(jí)葉片高度必須逐級(jí)加長(zhǎng)。大功率凝汽式汽輪機(jī)所需的排汽面積很大，末級(jí)葉片須做得很長(zhǎng)。汽輪機(jī)裝置的熱經(jīng)濟(jì)性用汽輪機(jī)熱耗率或熱效率表示。汽輪機(jī)熱耗率是每輸出單位機(jī)械功所消耗的蒸汽熱量，熱效率是輸出機(jī)械功與所耗蒸汽熱量之比。北京汽輪機(jī)檢修平臺(tái)</p><p
