Nitrogen generator equipment is widely used. Coal chemical industry, natural gas chemical industry, food nitrogen-filled packaging, and vegetable preservation are all inseparable from nitrogen generators. Nitrogen generators should be maintained daily during use, so as to prolong the use of nitrogen generators. Life, let me tell you in detail how to extend the service life of the nitrogen generator and how to perform daily maintenance?

First, How to effectively prolong the service life of the nitrogen generator?

Nitrogen production equipment is used in many industries, such as petrochemical, coal chemical, natural gas chemical, heat treatment, bright annealing, protective heating, food green storage, food nitrogen-filled packaging, vegetable preservation, wine sealing (canning) and preservation, etc. . If the nitrogen generator is used for a long time, the loss of the machine will be very large. Therefore, the nitrogen generator must be maintained in the daily operation process to effectively prolong the service life of the nitrogen generator.

1. It is necessary to ensure that the supporting equipment such as refrigeration dryers and suction dryers work normally, and must be operated in accordance with the instruction manual. The normal operation of air drying equipment is crucial to nitrogen production equipment.

2. Check the performance indicators such as the purity and gas production of the nitrogen making equipment; check whether the oxygen measuring instrument (oxygen analyzer) equipped with the nitrogen making equipment works normally, and whether the oxygen electrode needs to be replaced.

3. The pipeline filter should be checked regularly and the filter element should be replaced on time. The service life of the filter element is generally 2000-4000 working hours (depending on the air quality of the equipment used); the activated carbon in the activated carbon filter must be replaced for 7000 hours; the gas storage Tanks should be drained regularly.

4. If a large amount of powder is found at the outlet of the nitrogen generator, it indicates that aging or pulverization has occurred, and it is necessary to deal with it in time and replace the equipment filler.

Second, What are the routine maintenance of nitrogen system?

Daily maintenance of air compressor:
(1) Drainage of oil and gas drums: Open the drainage valve of oil and gas drums a little before starting the machine to drain the condensed water during shutdown, and close it immediately when there is lubricating oil flowing out. (2) Check the oil level: the oil level should be above the alarm line. (3) Check the changes of parameters such as exhaust temperature, lubricating oil temperature, and motor temperature when the air compressor is running. (4) Check whether the pipeline is leaking and whether the pipe joint is loose. (5) Whether there is any abnormal sound when the air compressor is running.

Filter routine maintenance:
(1) Check whether the drain valve at the bottom of the filter works normally. (2) Check whether the differential pressure gauge of the filter is in the normal display position.

Daily maintenance of nitrogen making equipment:
(1) Whether the manually operated valve is sensitive and normal. (2) Check whether the pressure value of the two-piece is at the set value. (3) Check whether the instrument display is normal. (4) Check the muffler for black powder.

The above is how to extend the service life of the nitrogen generator and how to carry out daily maintenance. I hope my summary can help you. If you have any questions, please leave a message at the bottom of the website.
