style="text-indent:25px">飽和蒸汽輪機是以飽和狀態(tài)的蒸汽作為新蒸汽的汽輪機。背壓式汽輪機供貨企業(yè)</p><p style="text-indent:25px">使用汽輪機的熱效率約為40%，另外，汽輪機的排汽壓力越低，蒸汽循環(huán)的熱效率就越高。不過排汽壓力主要取決凝汽器的真空度，真空度又取決于冷卻水的溫度和抽真空的設(shè)備（通常稱為真空泵），如果采用過低的排汽壓力，就需要增大冷卻水流量、增大凝汽器冷卻水和冷卻介質(zhì)的換熱面、降低被使用的冷卻水的溫度和抽真空的設(shè)備，較長的末級葉片，但同時真空太低又會導(dǎo)致汽輪機汽缸（低壓缸）的蒸汽流速加快，使汽輪機汽缸（低壓缸）差脹加劇，危及汽輪機安全運轉(zhuǎn)。背壓式汽輪機供貨企業(yè)</p><p
