Designing a Vacuum System
Designing a Vacuum System
(OP)
Hi,I'm in the middle of a project which concerns increasing the efficiency of a couple of Paper Machines.
We are at the moment concentrating on the vacuum pumps, and I have just worked out the needed power factor correction to increase the efficiency.
Currently there are 7 vacuum pumps used to draw off the water before the paper enters the press section.
However, someone has suggested that by using one large pump and a backup. Now, I am entirely unsure about how to go from here - do I need to sum the capacity of the smaller pumps to come up with the needed capacity of the bigger one? similarly with the pressure? Also, since I need differing pressures on the output, how do I go about seperating them?
Ive tried to find information on the internet, but I can't find much, if anything, about vacuum systems, just the pumps themselves. Any help would be much appreciated.

RE: Designing a Vacuum System
Maybe you can use nano-vacuum pumps, hundreds per press? %)

You could run some test cases with that program.

RE: Designing a Vacuum System
I've contacted www.graham-mfg.com and should receive the software in a few days. I shall also be contacting Nash to see what they say about the likelihood of this working, or whether I should just go a completely different route. (maybe not nano-vacuum pumps though!
I'll let you know what the results are.

There is one good link of sterling fluid systems, I have been referring to for quite some time in these forums. Do a keyword search on vacuum pumps and you can get it.
