Why do nitrogen systems need regular maintenance?

PSA (pressure swing adsorption) nitrogen generator uses carbon molecular sieve as adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air to separate nitrogen. Carbon molecular sieve is a kind of columnar granular adsorbent full of micropores on the surface and inside, which is made of coal as the main raw ...

What are nitrogen and helium used for in aerospace?

Gases that are heavily used in modern rocket and aerospace technology are nitrogen and helium. Their main applications are: 1. As an energy source, it is used to operate various pneumatic valves and components (helium gas should be used to operate liquid hydrogen cryogenic valves). 2. As a purge replacement gas. Blow out and replace the liquid propellant filling system ...

How PSA oxygen generator work?

The pressure swing adsorption oxygen generator is an automatic equipment that uses zeolite molecular sieve as the adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release nitrogen from the air, thereby separating oxygen. Zeolite molecular sieve is processed by a special pore type treatment process, and the spherical particle adsorbent full of micropores on ...

What are the routine maintenance of nitrogen system?

Daily maintenance of air compressor: (1) Drainage of oil and gas drums: Open the drain valve of oil and gas drums a little before starting the machine to drain the condensed water during shutdown, and close it immediately when there is lubricating oil flowing out. (2) Check the oil level: the oil level should be above the alarm line. (3) ...

How to deal with the phenomenon of soot spraying in the nitrogen generator?

The phenomenon of soot spraying of nitrogen generators is also called carbon molecular sieve pulverization, which occurs because the carbon molecular sieve is not tightly pressed or the carbon molecular sieve is loose. Structural faults of the adsorption tower caused by impact or equipment movement during the use of the nitrogen generator, such as the desoldering of the adsorption tower ...

How to extend the service life of nitrogen generator?

Nitrogen generators are used in many industries, such as petrochemical, coal chemical, natural gas chemical, heat treatment, bright annealing, protective heating, green grain storage, food nitrogen-filled packaging, vegetable preservation, wine sealing (canning) and preservation, etc. . If the nitrogen generator is used for a long time, the loss of the machine will be very large. Therefore, the nitrogen generator must ...
