Nitrogen machines are used in many industries, in petrochemical, coal chemical and natural gas chemical, heat treatment, bright annealing, heating, food storage, food green nitrogen-filled packaging, fresh vegetables, wine sealing (canning) and preservation. The long-term use of nitrogen machine, machine, the loss will be very large, so it is necessary to carry out maintenance during the daily operation of the nitrogen machine, extend the service life of the nitrogen machine.
1, the nitrogen machine extending up the equipment supporting the cold dryer, no heat regeneration dryer adsorbent and other equipment, to see whether it can work normally, must be carried out in the instruction manual. In particular, the normal operation of air drying equipment is the key to nitrogen equipment.
2, check the purity of nitrogen production equipment, natural gas production and other performance indicators; The oxygen analyzer detects whether the nitrogen production equipment (oxygen analyzer) is working properly and whether the oxygen electrode needs to be replaced.
3, the pipeline filter should be checked regularly, the filter should be replaced in time, the service life of the filter is generally 2000-4000 hours (such as the air quality of the equipment is different); Activated carbon filter Activated carbon 7000h must be replaced; The gas storage tank drains regularly. Compressed air mass nitrogen (oxygen) is essential for the proper operation of the machine.
4, nitrogen machine, nitrogen inlet valve and sampling valve closed, and turn off the power switch nitrogen machine. Wait for the end of adequate relief of the system and pipes (exhaust oxygen enrichment of the exhaust system, attention to fire safety, indoor air circulation, dredging). The pressure regulator of the oxygen analyzer adjusting sampling and reducing valve adjusts the sample to 1.0bar, and the flowmeter will reach about 1. Pay attention to the sampling volume should not be too large. The concentration detection requires nitrogen, and the oxygen content table indicates whether it meets the requirements.
5, if there is a lot of powder nitrogen machine, indicating the appearance of aging or powder, the need for timely treatment, it is best to replace the packaging of the equipment.
