Nitrogen generators have now become essential equipment for many companies, but many workers know how to operate but do not know how to maintain the equipment. For any machine, maintenance is very important. Good maintenance can effectively extend the service life of the nitrogen generator. In addition to maintenance, the correct use of the nitrogen generator is also vital to the extension of machinery and equipment.
Interpretation of the operation process: 1. Turn off all power switches, including the nitrogen generator, nitrogen inlet valve and sampling valve, and wait for the complete pressure relief of the system and pipelines. Adjust the oxygen analyzer for sampling and adjust the pressure of the pressure reducing valve to 1.0 bar, adjust the sampling flow meter, and adjust the gas volume to about 1. Note that the sampling gas volume should not be too large, and start testing the nitrogen purity. 2. Open the shut-off valve of the nitrogen generator only after the compressed air pressure reaches 0.7mpa or more. At the same time, pay attention to observe the pressure change of the adsorption tank and whether the pneumatic valve can work normally. 3. The pressure of the regeneration tower is zero. When it is uniform, the pressure of the two towers should be close to half of the pressure of the original working tower. 4. Close the entire system and all parts of the system. When the pressure of the adsorption tank of the nitrogen generator reaches about 0.6MPa, observe whether the nitrogen generator system is working normally.
