Help: What does \"safety barrier vacuum\" mean?
Thread Content
In the engineering documentation, there is the term “safety barrier vacuum”. I would like to ask those with more experience: how should it be translated? Also, please explain the meaning of this term. Thank you first!
This~~~ can you post the whole sentence? ? ?
I can’t find the original post for now. In 2015, I raised this question in the “Professional English” section, but I never received a response. Recently, in the instruments section, I saw that the more experienced users were providing very professional and detailed answers to various questions, so I brought up this question again in that section.
I have seen safety barriers before; I’m not sure what a vacuum is in this context.
My understanding — safety barrier isolation
Literally translated as: vacuum safety barrier. I wonder if such a thing exists?
Can a safety negative pressure barrier be considered a negative pressure system similar to a fume hood?
Literally: vacuum isolation barrier? Insufficient information makes it unclear what the actual use is
