The ratio between the air production of the hollow press and the nitrogen production of PSA

In the process of using the nitrogen machine, the common problems that users will encounter are:

1. What is the ratio between the air production of the air compressor and the nitrogen production of PSA? Calculation formula and method?
A: Safe conservative design 5 to 5.6:1.

PSA nitrogen machines with different purity consume different amounts of compressed air and the ratio of nitrogen gas production is different, the higher the purity of nitrogen, the greater the amount of compressed air consumed. The ratio of 99.99% purity nitrogen machine is 5~ 5.6:1.

2. When the air compressor has a surplus and no surplus, how much impact on the energy consumption of producing the same cubic amount of nitrogen (such as 1 cubic)?
A: Different models, the same actual output, little difference in power consumption.

When the air compressor has no spare capacity, the air compressor has been running in the loading state, and the theoretical exhaust volume of the air compressor is equal to the compressed air of the PSA nitrogen maker, which is the lowest in terms of the nitrogen energy consumption produced.

When the air compressor exhaust capacity has a margin, the air compressor is sometimes in the unloading state, and the power consumption of the compressor during unloading is 30% of the loading time, and it is slightly higher in terms of the output nitrogen energy consumption.
