kasri,

Have a look at the blog entry:

http://www.cheresour...r-seal-systems/

I have mentioned some literature resources for compressor seal systems. These resources should guide you for the fundamentals related to compressor seal systems. The attachement to the blog specifically defines seal gas systems for centrifugal compressors.

Hope this helps.

Kasri,

Yo will have to read a lot on the subject using rotating machinery textbooks, . It is difficult for me to explain in detail since I am not a mechanical engineer with vast experience on the subject. Basic fundamentals related to compressor seal systems are very well covered in:

Compressors - Selection & Sizing, 3rd Edition by Royce. N Brown.

Some internet resources can be found at the following links:

Hope this helps.

Regards,
Ankur.

Kasri,
Is there a specific sealing system that you are talking about? If you can upload a diagram of the seal system that you are dealing with, then we will be able to explain it more clearly.
