Ultimately I'd like an automated pressure control loop I can just leave, type in a pressure setpoint and then run a slow speed ramp on the compressor, ie 0-3000 rpm over say 45 secs and control the back pressure all the way up (once sufficient pressure has been built up), this is my ideal...
Thanks for the replies so far. The theory of controlling the two valves in parallel would be.
Smaller valve P.V comes from a pressure transducer mounted on the tank (in between compressor and valve/s), this is the pressure we wish to maintain.
Larger valve P.V comes from the position of the...
All,
I've an application coming up where we're doing some R&D testing on air compressors, this requires a pressure map to be completed at various speeds and back pressures. Back pressure on the compressor is normally controlled via a valve downstream of the compressor outlet and subsequently...
