Maintenance Of Nitrogen Making Machine

1. general protection and maintenance

In order to ensure the stability and reliability of the system for a long time, it is necessary for the users to do some daily protection operations. The random instructions of all the equipment in the system are discussed in detail, and it is necessary to follow the requirements of their instructions for protection and maintenance. The first includes the following:

  • Whether the operation of the solenoid valve is normal;

  • The system of equipment pipeline, fittings for damage, leakage and other phenomena;

  • The system of equipment electrical control part of the wiring is strong, electrical components are normal;

  • Dust cleaning and cleaning operation.

2.Replacement of filter core

The filter core of the three stage filter of the NZN series PSA is required to be replaced regularly. If the filter before and after the pressure is greater than or equal to 0.05 ~ 0.1Mpa, it is necessary to replace the filter element.

Replace: screw down the shell of the filter core, then spin the core of the filter, change into the new core, then spin the shell, and tighten it. Note: the replacement of the filter core should be carried out when the system is discontinued and it is necessary to unload the pressure in the pipeline. Otherwise, it may lead to serious damage to life. When replacing the core of the filter, a metal ring or a "O" seal ring can not be damaged or sealed. Otherwise, the filter will not be used. In addition, all filters have active discharge function. But you still need to see an active sewage equipment once a week.

3. time maintenance

The micro nitrogen analyzer needs to be calibrated regularly (see the instruction manual in detail). If the analyzer appears accurate and the system work is normal, the failure of the molecular sieve can be considered when the product is unable to reach the target. If the failure is confirmed, molecular sieves should be replaced. It is necessary to end up with professional and technical personnel.


Nitrogen is a colorless, odorless, chemically lazy gas. It is a simple asphyxiant. In the operation of the equipment, it is necessary to pay attention to the maintenance of indoor ventilation.

The optimum operating parameters of the nitrogen making machine are 0.75~0.90MPa, and the corresponding adjustment should be made when the parameters of the compressor are set.
