Can a multi-stage jet vacuum pumping system achieve different levels of vacuum within the same device?
Thread Content
We are currently designing a retrofitting device. Within the same unit, there are two systems that require different levels of vacuum. Is it possible to use a single vacuum pumping system for this purpose, and if so, how? Could different stages of multi-stage vacuum pumping be utilized? We would appreciate advice from experts. Thank you in advance.
Please refer to “A device has two negative-pressure towers; can one vacuum system be used?” http://bbs.hcbbs.com/thread-575923-1-4.html
This is achievable; the ejector pump can be designed in a two-stage format to achieve different levels of vacuum, but it’s not entirely clear as to how exactly it should be designed. The poster can call a department at the 11th Institute of the Aerospace Ministry; they have experience in design and practical application.
By adjusting the vacuuming efficiency, it is possible to achieve
