The carbon molecular sieve has a high demand for the quality of compressed air, and the compressed air contains a lot of water and a certain amount of dust and oil mist, so it is necessary to cool down, remove water and remove oil before the compressed air enters the nitrogen machine. The purification of compressed air is crucial, which should not be ignored! Because the quality of compressed air purification treatment is directly related to the service life of carbon molecules, and then directly related to the long-term effective use of nitrogen production machine.

First, nitrogen machine boot process

1) Turn on the cold and dry machine and pre-cool for five minutes.

2) Open the air valve into the cold dryer, let the compressed air into the cold dryer for water, oil and dust removal.

3) Open the air valve that enters the nitrogen production vitality, and let the dry and clean air enter the nitrogen production vitality.

4) Turn on the power supply and emergency switch of nitrogen production vitality, and the engine unit enters the working condition.

5) Wait 15 minutes for nitrogen production to have enough time to make nitrogen.

Second, nitrogen machine shutdown process

1) Press the stop switch and power switch of the nitrogen making machine.

2) Close the power switch of the cold and dry machine.

3) Close the air valve entering the nitrogen machine.

4) If not used for a long time, the total power supply will be blocked.

Iii. Others

1) Please check whether the cold dryer is working normally every day, and use the air gun to test whether the water and oil in the air are overspent.

2) Please adhere to the pressure of nitrogen reservoir, do not empty.

3) Please adhere to the nitrogen machine fuselage surrounding environment health, clean and tidy.

4. Attention to the use of nitrogen machine

1. The use of 220V power supply in all nitrogen production systems, please pay attention to power safety, non-professionals do not operate electrical appliances or unauthorized circuit modification.

2. Before opening the nitrogen production vitality, it is necessary to ensure that the imported compressed air pressure is above 0.7Mpa, otherwise the power of the nitrogen machine can not be completely performed.

3. It is necessary to admit that the compressed air treatment equipment (frozen or adsorption dry machine) is in working condition and can handle most of the oil, water, dust and impurities in the compressed air.

4. The extra exhaust pressure of the air compressor is the best choice of 0.8-1.0Mpa(at least ≥0.75Mpa), and the oil content in the compressed air is necessary to be less than or equal to 10ppm w/w.

5. Before use, open the power supply of the cold drying machine, let the cold drying machine pre-cool for 5 minutes, and then open the nitrogen production vitality.

6. Maintenance and protection according to the technical requirements of air compressor and dry machine to ensure air quality. It is necessary for air compressors and cold drying machines to be repaired and maintained at least once a year.

7. Record the use date of each pre-screening program and replace its filter element regularly.

8. For nitrogen production, it is best to use copper or stainless steel pipes (followed by galvanized pipes) for threaded connection or welding.

9. Do not arbitrarily move the electrical equipment in the electric control cabinet, and do not arbitrarily remove the pneumatic pipeline valve. The valve adjusted by the debugging personnel should not be turned at will, so as not to affect the purity of nitrogen.

10. Assign full-time operation protection management personnel, and make special training. The appearance of the equipment must be clean and clean, and often wipe with a wet cloth or neutral soapy water.
