Nitrogen making machine has become a necessary equipment for many enterprises, but many workers know how to operate, but do not know how to maintain equipment.
For any machine, maintenance is very important, good maintenance can effectively prolong the service life of the machine. except
In addition to maintenance, the proper use of nitrogen making machine is very important for the extension of the equipment.
Interpretation of operation process of nitrogen making machine:
1, turn off all power switches, including nitrogen and nitrogen inlet valve and sampling valve, waiting for the end of the system and pipeline pressure relief. Regulation of oxygen analyzer sampling and valve pressure adjustment to adjust the sample 1.0bar, flow meter, gas will be transferred to around 1, pay attention to sampling volume should not be too large, began testing the purity of nitrogen.
2, in the compressed air pressure to reach more than 0.7MPa, in order to open the nitrogen machine valve, at the same time, we should pay attention to observe the adsorption tank pressure change and pneumatic valve can work normally.
3, the regeneration tower pressure is zero, the pressure of the two tower should be close to half of the original working tower pressure.
4, shut down the whole system and the various parts of the system, when the nitrogen adsorption tank pressure reaches 0.6MPa or so, to observe whether the nitrogen system is working properly.
