Working principle of nitrogen generator
Thread Content
Guys, any help finding an animated video on the working principle of nitrogen generators? In PSA adsorption nitrogen generators, one of the working valves or solenoid valves fails to function properly; it’s not possible to determine exactly which valve is the issue. The problem occurs for a few seconds at a time, causing a sharp drop in the pressure of compressed air in the system, yet it’s impossible to identify which valve is problematic Therefore, I am seeking animated videos to help me take a look.

Are there detailed values displayed by the PLC?
It has been resolved. Replaced a pneumatic valve
The PSA nitrogen generation unit uses an adsorber as its main component, and it is combined with a programmer and control valves to form a complete nitrogen generation system. At the point of use, the operator feeds the compressed air discharged by the air compressor into the adsorber (A); oxygen and water vapor in the air are preferentially absorbed by the carbon molecular sieve, while the pure nitrogen gas that emerges from the bottom of the adsorber enters the buffer tank. At this time, the other adsorber (B) is undergoing regeneration. The air first passes through a pressure reducing valve and then is released through a silencer. Once the desired operating pressure is reached, the exhaust valve is closed, and fresh air is slowly introduced into the regenerating adsorber (B). Once the pressure is balanced, the valve at the bottom of the adsorber opens, allowing qualified nitrogen to be released again. Meanwhile, adsorber A enters its regeneration mode. The adsorption and regeneration processes of the two adsorber groups A and B are controlled by a programmer, which opens and closes various valves in sequence according to a preset program and timing, thereby enabling adsorption (to produce qualified nitrogen), regeneration (by reducing pressure and draining air), and pressurization to take place in an orderly and continuous manner
