Modeling
Software for Compressor Operators and Engineers
With so many compressors, so many performance methods, so many PLC implementations
and so many restrictions for safe use, ACI's eRCM Modeling Software
provides the perfect solution to model compressor performance curves.
You simply specify the compressor's geometry (frame, cylinder, stage,
throw, valving, etc.) via direct inputs or from our extensive database
of OEM and legacy records and eRCM displays that unit's
performance curves: Pressures vs. Load, Pressure vs. Flow, Pressure
vs. Pressure and more, including graphs of net rod load forces and PV/PT
cards.
Operating conditions always change. If you need to know if
adding a 500 cubic inch unloader to your fifth cylinder's head end will
give you enough unloading to accommodate the new operating map, then
eRCM is for you. Within seconds you'll have your answer(*).
Tired of Gas Control using one method to predict unit performance,
while you're using another, and the PLC is using yet another method
to actually control the hardware? eRCM provides one methodology for
all users -- yes, we even generate the algorithms that will go into
the PLC to control the unit!
Want to see if the packager's unloading sequence can be improved? With
eRCM you can easily check any combination of volume pockets and end
deactivation. Including adding spacers to increase fixed clearances
or adding filler pieces to volume pockets to decrease additional clearances.
No compressor performance program would be complete without the ability
to get smarter. eRCM does just this. Enter analyzer data in the tuning
section, and eRCM will auto-adapt the performance predictions to accommodate
the real-world effects of pulsation, actual valve and parasitic losses,
friction losses, etc.
