What are the reasons why the nitrogen purity produced by the nitrogen generator does not meet the design specifications? Dear sea friends, please help analyze and solve this issue. Thank you!
Could you describe the problem more clearly? For example, the process there
1. The air-to-nitrogen ratio is not appropriate; in other words, the amount of air is insufficient or the adsorbent is not effective, resulting in inadequate nitrogen production capacity； 2. There are issues with the program settings; the timing and duration for processes such as adsorption and regeneration are incorrect
1. Excessive outlet flow 2. Partial deactivation of the adsorbent 3. Lack of adsorbent or leakage from the adsorbent 4. Internal leakage or sticking of the solenoid valve 5. Delay or error in the switching valve’s programming
This can be caused by many different reasons. Such as pressure, valves, etc
There are many possible reasons; conduct debugging by analyzing factors such as flow rate, purity, various valves, molecular sieves, and even the air compressors and cold dryers at the source
We can analyze this from the following aspects: 1. Does the air purification system meet the standards? 2. Is the flow rate of the nitrogen generator too high? 3. What is the ratio of instrument air to nitrogen? 4. Is the air pressure meeting the requirements? 5. What is the molecular sieve regeneration interval?
