Why does the new hydrogen compressor require primary nitrogen isolation and secondary nitrogen isolation? Why is the pressure higher in the primary stage?

Why does the new hydrogen compressor require primary nitrogen isolation and secondary nitrogen isolation? Since the pressure in one stage is higher, why is the pressure different?
You are referring to the reciprocating compressor in the hydrogenation unit, right? Isolating nitrogen is done to prevent hydrogen from escaping in case of leaks in the sealing components, as well as to stop the oil from the wiper rings from entering the compression cylinder
The first stage removes the leaked hydrogen gas, while the second stage prevents hydrogen gas from passing through the intermediate filler and entering the crankcase, thereby avoiding explosions
Stage 1 is located near the cylinder side and is the area with high pressure
