What are the operation precautions of nitrogen filling nitrogen machine in food preservation industry
1. Adjust the nitrogen production valve after the flow meter according to the gas pressure and gas consumption, and 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 best purity;
3, nitrogen analyzer flowmeter should be adjusted to 0.5L/h scale;
4, the valve adjusted by the debugging personnel should not be rotated at will, so as not to affect the purity;
5, do not arbitrarily move the electrical parts in the control cabinet, do not arbitrarily remove the pneumatic pipe valve;
6, the operator should regularly check the pressure gauge on the nitrogen machine, and make a daily record of its pressure changes for equipment failure analysis;
7. Regularly observe the outlet pressure, flowmeter indication and nitrogen purity, compare with the required value, and solve the problem in time;
8, according to the technical requirements of air compressor, cold dryer, filter maintenance and maintenance to ensure air quality (air source must
No oil). Air compressor, dry machine must be repaired at least once a year, according to the equipment maintenance, maintenance regulations easy to replace
Damaged parts and maintenance.
9, air separation nitrogen equipment in the process of work, carbon molecular sieve has a certain wear, should be inspected and filled once a year molecular sieve.
10. Complete the daily record form.
