From the composition of nitrogen generator, only two main factors affect its stability, namely control valve and carbon molecular sieve.
The performance of PSA nitrogen generator: an excellent material, good sealing, no air leakage. It can accept frequent opening and closing actions to ensure the service life, and can quickly complete the switching action within receiving the control signal (about 0.02 seconds).
The valve cycle (every 60 seconds) must open and close. The nitrogen generator works 300 working days a year, 24 hours a day. The adsorption and desorption cycle is 4 minutes, so each valve needs to be opened and closed more than 200,000 times per year. time. As soon as one of the valves fails, the entire plant is affected. Therefore, the continuous service life of the valve is an important part of the stability and reliability of the nitrogen generator.
