Design pipes! ! !

It is a sealed furnace; the inlet pressure is required to reach 750 mbar within 4.5 seconds, and then 850 mbar within another 2.5 seconds. After that, air is supplied at a constant pressure increase! The key requirement is that no pressure drop should occur during the intermediate switching process, with a constant pressure increase after 850 mbar. Time control requirements are included as well! Currently, I am using a method of stopping in segments through three air inlets for testing, but the desired results are not achieved at the turning points; surging and pressure drop occur! Can some improvements be made to the piping design to prevent pressure spikes and drops inside the hermetically sealed furnace? ! ! Thank you so much for your help! ! !
