First, the nitrogen machine basically does not need periodic maintenance.
When all the equipment is overhauled, check whether the nitrogen machine is running normally. The periodic maintenance of the air-cooled dry machine is mainly to purge regularly and clean the sewage outlet; Please read the operation and maintenance manual of the cold dryer carefully, and maintain the cold dryer strictly according to the periodic maintenance methods and measures recommended by the cold dryer manufacturer.
In order to ensure the stable and reliable operation of the nitrogen system and the long service life of the compressor, the compressor must be maintained according to the periodic maintenance methods and measures recommended by the compressor manufacturer.
The maintenance of the oil screw air compressor is mainly the periodic replacement of the intake air filter (which will be blocked by dust), as well as the annual replacement of the lubricating oil and oil separator. Compressor maintenance also includes regular replenishment and replacement of oil.
The periodic maintenance of the filter is mainly to replace the filter element regularly according to the use of the filter. If you find that the pressure difference of the filter is too large, please replace the filter element in time.

Second, nitrogen machine equipment daily maintenance:
The maintenance of the equipment in the nitrogen making machine system mainly includes the maintenance of air compressor, cold and dry machine, filter and nitrogen making host. The daily maintenance of air compressor is mainly:
1. The radiator of the cold dryer should be cleaned frequently;
2. The sewage outlet of the filter should be checked frequently whether it is blocked;
3. The exhaust port of the nitrogen silencer should be checked regularly whether it is smooth;
4. The appearance of all equipment of the nitrogen machine should be kept clean and clean, and often scrubbed with a wet cloth or neutral soapy water;
5. It is necessary to regularly check whether the sewage outlet of the air compressor storage tank is blocked and whether the heat dissipation hole is blocked.
