Reply #52018-01-14
from. Mesdames et messieurs les grands maîtrestres们: 请问真空突然变得更好,重新启动真空泵后恢复正常是怎么回事?
Reply #62018-01-16
我从没遇到过这种情况,让生产厂家来解释一下吧。

重新启动后是否过一会儿又这样? 还是先检查管道吧

是室外机组吧? 因为水环真空泵温度越低,水分蒸发越慢。吸气口蒸发出的水分就会提高真空度。 真空泵使用压强与温度、空气成份、体积都有关联,温度低,负压越高。~~~楼主测下循环液的温度~~~可以用循环冷却水或电加热或蒸汽来调调温

真空泵停运系统的不凝气体排不出真空度会缓慢降低

在2小时内出现了3次,目前已经正常连续运转了好几天了

" 是在室内,但是我们用的是板式换热器循环水,板式换热器是用冷冻水换热降温的,冷冻水设置温度为6、7度。我个人理解是水温高,水蒸发会影响真空度,温度低也会影响?

" 曾经有一次,关于真空不高的问题,我们三个人查了两天,最后发现原来是压力表坏了
