1.The adsorption pressure of the nitrogen machine is unstable, such as too high, more than 0.8Mpa or too low adsorption pressure, less than 0.6Mpa;
2. Too much water oil in the gas source;
3. Outlet part of the interface leakage;
4. The pressure of excessive intake volume rises too fast;
5. molecular sieve poisoning of nitrogen machine.
The solution measures that can be taken are as follows to improve the purity of nitrogen making machine:
1, reduce the air pressure, increase the intake pressure
2. Add a storage tank to the air intake
3. Remove and reinsert
4. Replace the molecular sieve
5. Adjust the inlet regulating valve of the nitrogen machine to reduce the intake volume, and install an oil-water separator before the inlet
