So i'm trying to wrap my head around this...
So during sandblasting my 15CFM compressor cant keep up. It runs almost constantly way over its duty cycle and runs quite hot which doesn't help for water. Will adding a second compressor in help by sharing the load between the two?
Bloody confused.
Lets say I want 100 PSI for sandblasting at 15CFM
And I have a 200L 15CFM, rated 10 bar compressor (A) chained in parallel with a 100L 15CFM compressor, rated 8 bar (B) with a Y into a common regulator.
Now lets say compressor A is set to turn on at a tank pressure of 110psi and off at 145 psi
And compressor B is set to turn on at 100 psi tank pressure and off at 116 psi
So, we have 145 psi in tank A, 116psi in tank B.
Turning the sandblaster on both tanks begin draining.
Am I correct in thinking tank B will hit 100psi before tank at hits 110psi?
So compressor B turns on, both tanks are still losing pressure, but now A is losing it more rapidly than B
B is still on, and tank A pressure hits 110psi and the compressor A turns on.
Now both compressors are running and the pressure builds in both tanks.
Now tank B is full at 116psi, compressor turns off
but tank A isn't full yet, so it can't reach 145 psi to turn off
So now A is on, pressure drops and B turns on at 100psi
Pressure in both rises, B turns off at 116psi.
Pressure falls, A turns on at 110psi...
Repeat...
OK so this has really muddled my head up, it looks like its difficult to do with two different target pressures?
Let's say the target pressure is 116psi for both compressors.
With A turning on at 100psi and B at 103 PSI
Pressure falls in both
B hits 103 PSI turns on, pressure still falling
A hits 100 PSI turns on, pressures in both tanks rise to 116psi}
Compressors resting... tanks draining
B hits 103 PSI...process repeats
So if we have 30CFM combined then that should equate for 50% duty cycle for both compressors if they are set to the same target pressure and a similar kick-in pressure?
Is this the correct way to reduce the duty cycle for both compressors?
