Re: How much air do we need?
Just as a point of reference...
It takes the compressor about 15 seconds to fill one accumulator (16 in3) to the max 120psi from 0psi.
Two accumulators take twice as long (30 sec.) to fill.
Four accumulators take four times as long to fill completely (1 minute).
The solenoids stop working when the system pressure falls below 20 psi (SMC) to 30 psi (Festo).
So when doing an initial rough estimate of the air available to you you can assume at MOST you will have:
-- (4) accumulator's worth of air from pre-charging your leak-free pneumatic system prior to a match
-- (8) accumulator's worth running the compressor for the 2 min. teleop period
-- (1) accumulator worth during the 15 sec of the hybrid period
