What are the precautions for the operation of nitrogen-filled nitrogen generators in the food preservation industry?

1. According to the gas production pressure and the gas consumption, adjust the nitrogen production valve after the flow meter, do not adjust the flow rate at will to ensure the normal operation of the equipment;

2. The opening of the nitrogen gas production valve should not be too large to ensure the purity meets the requirements;

3. The nitrogen analyzer flow meter should be adjusted to 0.5L/h scale;

4. Do not rotate the valve adjusted by the commissioning personnel to avoid affecting the purity;

5. Do not move the electrical components inside the control cabinet at random. Do not disassemble the pneumatic pipeline valves at will;

6. The operator should regularly check the pressure gauge on the nitrogen generator to make a daily record of the pressure change for equipment failure analysis;

7. Regularly observe the outlet pressure, flow meter indication and nitrogen purity, and compare with the required values ​​to find out the problem in time;

8. Maintenance and maintenance according to the technical requirements of air compressor, dryer and filter to ensure air quality (air source must be oil-free). The air compressor and the dryer must be repaired at least once a year, and the consumables should be replaced and maintained according to the equipment maintenance and maintenance regulations.

9. During the working process of the air separation nitrogen plant , the carbon molecular sieve has certain wear and tear, and the molecular sieve should be inspected once a year. 10. Complete the daily record form.
