After understanding carbon molecular sieve, we should also look at the nitrogen generator, which is an important machine for manufacturing carbon molecular sieve. Carbon molecular sieve nitrogen generator is also called PSA nitrogen generator. Its core component is carbon molecular sieve. Carbon molecular sieve has a very harsh working environment. The compressed air oil, water impurities provided by the air compressor need to be filtered cleaned. Check the sewage system regularly.
The replacement time of carbon molecular sieve in PSA nitrogen generator mainly depends on the actual nitrogen purity of nitrogen output nitrogen generator. Any fault of the nitrogen generator will directly affect the purity of nitrogen in the nitrogen generator. Some users will advise me to see that the display of our nitrogen generator P860 nitrogen analyzer also meets the standard. The price of the instrument is moderate, but the life of oxygen electrode is very short for half a year. Since it is recommended to replace the instrument every two years, customers will forget to replace the instrument after using it for a period of time. The nitrogen analyzer has shown 99.9%, 99.99%, 99.999%, the user of nitrogen generator has been correctly maintained. What's the problem? Under what circumstances should carbon molecules in the nitrogen generator be replaced?
1. PSA pressure swing adsorption nitrogen generator is also called carbon molecular sieve. The core of nitrogen generator is carbon molecular sieve. Carbon molecular sieves have very strict working requirements. The compressed air oil, water impurities provided by air compressor need to be filtered cleaned to remove sewage. The system will regularly check whether the filtering drying consumables are replaced regularly to avoid long maintenance cycle. Carbon poisoning (water in the carbon molecular sieve of nitrogen generator in oil) will lead to the replacement of carbon molecules in nitrogen generator in advance, which will increase the equipment cost.
2. The difference between the compaction device of nitrogen generator the existing cylinder, spring air bag is tight. Although the cylinder can be monitored in real time, carbon molecules are crushed added due to lack addition. The injury caused the nitrogen generator to emit black smoke. At this time, the whole system needs to be replaced by carbon molecular sieve. If carbon molecular sieve is usually added at this time, the carbon molecular sieve will pop up continuously, the consequences will be more more serious. The entire nitrogen piping system will have nitrogen generator carbon molecular sieve powder.
3. The structure of nitrogen generator was destroyed the pipeline was disassembled welded, resulting in insufficient carbon molecules in nitrogen generator. It is necessary to test the air tightness of the adsorption tower structure of the nitrogen generator, find the position of the flux replace it with a new carbon molecular sieve.
