style="text-indent:25px">液壓快速接頭的作用：(1)調(diào)整汽溫，使鍋爐送出的蒸汽溫度在規(guī)定的范圍內(nèi)。汽輪機對蒸汽溫度要求很嚴(yán)格，一般要求比額定汽溫正負(fù)不超過5℃，即汽溫只能允許在10℃范圍內(nèi)波動。汽溫超過規(guī)定值，會使過熱器、蒸汽管道、汽輪機及接頭等設(shè)備壽命降低，嚴(yán)重時可使上述設(shè)備損壞。汽溫低于規(guī)定值，會降低機組的經(jīng)濟性。汽溫降低10℃，機組的經(jīng)濟性降低0.6%～0.8%。由于影響汽溫的因素很多，為了保持蒸汽溫度在規(guī)定范圍內(nèi)，必須對蒸汽溫度進行調(diào)整。調(diào)整汽溫的方法很多，液壓快速接頭調(diào)整汽溫是普遍采用的方法。</p><p
