"汽轮机응기기 냉각기 흡기 문제",
Reply #22017-05-06
"증기기응기기의 경우, 냉각기의 압력은 약 - KPa(절대 압력)까지 떨어지게 하기 위해 증기 분사 흡기기로 냉각기 압력을 음압으로 떨어트립니다. 증기기의 휘성기실 내 고압 증기가 압력이 낮아지면 냉각기로 들어갑니다. 그렇다면 흡기기는 부분적으로 저압 증기를 빼내는가요? 아니면 냉각기의 구조는 어떻게 설계되었는가요?"

"첫째, 빈도는 형성되지 않아서는 증기기 냉각기形成的真空不是通过抽气器抽出来的,而是由于气体变成水的过程中比体积的变化形成的。抽气器只是维持保持真空。如果真空度过高高高会把没有做完功的蒸汽抽出来增大蒸汽机蒸汽的消耗所以真空也不能过高"

nâng 温度对应的饱和蒸汽压,约 1 KPa"

"주로 主主要是靠蒸汽的相变产生负压蒸汽的相变体积发生近一千五百倍的变化。抽气只是辅助作用把不凝气抽走"

"부분적으로 증기가没有蒸汽可以抽出部分部分未冷凝的蒸汽这部分蒸汽在抽气器中再次冷凝回到复水器的阀井当中而不凝气则排到大气中"
