PSA time setting
Thread Content
Why is the PSA time set as t1 > t3 and t2 > t4? It’s explained as a way to equalize the pressure in both towers – don’t get it? Please provide an explanation
Where was it designed, and what is the manufacturing process? The PSA systems of different design institutes are distinct, and the meaning of time also varies
What do T1, T2, T3, and T4 each represent? T2 should be included within the time frame of T1, and it must meet the minimum time requirement for this step
Different design institutes use different ways to divide PSA time slots; the original poster should send us a timing table so that we can study it. Different numbers of voltage equalization cycles imply different meanings as well. I hope the original poster can post a picture so we can learn from it*.
