["진공 泵의 계산 문제에 대해请教各位大神一个关于真空泵的计算问题?", "초보자 한 명입니다. 진공机组泵的选择是如何进行的?其中涉及的计算公式有哪些?? "진공 泵选型,其实选真空泵的抽气速率,确定抽气速率后根据你要求的真空泵类型(比如比如水冲泵、水环泵、往复泵、螺杆泵、罗茨泵等等),那么功率也就定了。 �给你你一个简单的估算公式吧 : S=(V/t)×ln(P�/P2)   其中:S为真空泵抽气速率 ,单位为(L/s)   V为真空室容积 ,单位为(L)   t为达到要求真空度所需时间 ,单位为(s)   P�为初始绝压强 ,单位为(Pa)   P2为要求绝压强 ,单位为(Pa)"]

真空泵选型,其实就是选真空泵的抽气速率,抽气速率定了,根据你要求的真空泵类型(比如水冲泵、水环泵、往复泵、螺杆泵、罗茨泵等),那么功率也就定了。 给你一个简单的估算公式吧: S=(V/t)×ln(P1/P2)   其中:S为真空泵抽气速率,单位为(L/s)   V为真空室容积,单位为(L)   t为达到要求真空度所需时间,单位为(s)   P1为初始绝压强,单位为(Pa)   P2为要求绝压强,单位为(Pa)
