A complete Nitrogen Machine will have a lot of ancillary equipment! One
of the most important one is the air compressor, the current pressure
on the market to absorb the main raw materials are nitrogen high-quality
compressed air, when it comes to compressed air, of course, that air
compressor, and now the world's three major brands of air pressure Machine: the United States Sullair, Atlas, Ingersoll Rand, and these
big brands to do matching, mainly because the nitrogen machine on the
compressed air requirements a bit high:
First,
the compressed air oil content must be less than 0.003ppm, the
compressed air outlet pressure must be controlled between 0.75Mpa to
1.2Mpa, due to compressed air from the air compressor system to the
nitrogen system in the process of pressure loss, so the air pressure Machine
generally supporting 0.8Mpa, and secondly because the working principle
of nitrogen generator is pressure swing adsorption, so the pressure of
air compressor is very important, which determines the quality of
nitrogen nitrogen nitrogen machine is good or bad, but not to say that
the pressure The bigger the better, the pressure to 1.2Mpa, it will lead to molecular sieve crushing, it must be less than 1.2Mpa.
Nitrogen
machine is generally the best choice of screw-type air compressor,
piston machine outlet temperature is high, which will directly affect
the life of molecular sieve, and air post-processing equipment filter
replacement is also more frequent, three imported brands imported air
compressor oil The
amount of control is generally less than 3PPm, domestic air compressor
oil content is high, the export temperature is high, under normal
circumstances will be installed degreasing activated carbon filter, or
else the life of the molecular sieve greatly reduced, nitrogen machine Imported
molecular sieve market prices are generally more expensive, if the
comprehensive consideration of the latter part of the maintenance costs
and cost-effective, it is best to choose the choice of imported air
compressor screw machine, but for small cubic nitrogen machine, you can
choose domestic air compressor.
