In fact, the explosion-proof nitrogen generator itself is a very durable device. Under normal circumstances, there will be no failures. The focus is on the pre-stage of the explosion-proof nitrogen generator - the compressed air purification component.

 

The following are some precautions for the maintenance of explosion-proof nitrogen generators:

 

1. Main pipeline filter element: replace it every 6 months;

 

2. Precision filter element: replace it every 12 months;

 

3. Ultrafine filter element: replace it every 12 months;

 

4. Nitrogen generator activated carbon (activated carbon filter): replace it every 6 months;

 

5. Automatic drain valve (automatic drain valve): pay attention to observation during operation, if it does not drain, it should be cleaned or replaced in time;

 

6. The normal life of the solenoid valve is 5-10 years;

 

7. Nitrogen analyzer sensor: The sensor life of different analytical instruments is different;

 

8. The normal service life of the pneumatic valve is 3 to 10 million times of opening and closing, which varies according to the working conditions of the customer;

 

9. Carbon molecular sieve of explosion-proof nitrogen generator: according to the cleanliness of the gas source of the customer, the service life is different, generally 5-10 years do not need to be replaced;

 

10. Freeze dryer: Regularly check the refrigerant and drain valve;

 

In the process of using the explosion-proof nitrogen generator, we must maintain it as much as possible, rather than waiting for the explosion-proof nitrogen generator to be repaired. The concept is correct.
