Hello everyone,
I am trying to size an air starting system for a gas engine driven compressor. I have a question regarding air receiver and pressure regulator downstream of the receiver.
Let’s say for instance upper limit of pressure for receiver is 120 psig and lower limit is 90 psig. I have set my self contained pressure regulator at 120 psig for example i.e. it will maintain 120 psig at its downstream. The air compressor cut in pressure is 90 psig and cut off pressure is 125 psig. When there is a demand of starting air, as per my understanding the pressure in the air receiver will go down…lets say the pressure at one instant is 110 psig…will the regulator work ..which is set to maintain 120 psig downstream? Since it will have 110 psig at its inlet, I assume it would not allow any flow through it
