Gas Booster Pressure Control

[sarahr]

Hi everyone-

I have a question about pressure control. I have to design a system that will use a gas booster (with two pistons) to control the pressure. I've only used gas boosters in one other design, and it was with a constant supply pressure. However, this design is going to be working with a manifold to supply the gas to the boosters, and the manifold is not at a constant pressure. It varies depending on the amount of air supplied. Can anyone think of a way to design the system so that the air being supplied to the gas booster can be regulated to a constant pressure?

Thanks!

Would it be possible to put a pressure regulator upstream of the boosters?

For a non-automated system, I'd stick a remote-sensing regulator on the supply line, and the regulator's sensing line on the output of the boodter. If the booster output pressure gets too high, the supply air gets pinched off a little, and eveything is....regulated. Pretty much the same way they did "Pump Governors 'way back when.

If you have the infrastructure to automate it, then stick a control valve on the energy source and a pressure transmitter on the output line. It's completely analagous to the above, but it would let you use PID software and really dial it in .

Thanks! Those are both great ideas and I'm looking into them as options. Thanks for your help.
