The nitrogen generator is the core equipment of the nitrogen production system, and with proper maintenance, its life can extend for decades. The goal of maintaining a nitrogen generator is to ensure its normal operation and prolong its service life. Among them, the carbon molecular sieve is a critical component of the nitrogen generation equipment and requires special attention. Additionally, proper maintenance of other components also contributes to extending the lifespan of the nitrogen generator.
This article will explain how to maintain a nitrogen generator.
Filling and Replacement of Carbon Molecular Sieve
After prolonged use, the carbon molecular sieve in the nitrogen generator naturally wears out, causing it to sink. When the cylinder alarms for the first time, contact the company’s after-sales service department immediately to plan for molecular sieve replacement.
The quality and filling density of the carbon molecular sieve are important process indicators affecting the performance of the nitrogen generation equipment. The model and quantity of the molecular sieve must be confirmed by technical personnel from the supplier before filling.
The supplier’s personnel use specialized filling tools and technical requirements for filling. If there is a need to fill the molecular sieve after equipment maintenance, the supplier’s personnel should be notified to carry out the task.
Maintenance of Other Components
Regularly check the pressure gauge of the cylinder. If there is no pressure or if the pressure drops during the desorption process, it indicates that the cylinder cannot compress the carbon molecular sieve properly. The fault should be promptly eliminated to prevent the carbon molecular sieve from not being compressed properly and causing sieve pulverization. When the molecular sieve gap rearranges or normal wear occurs, it’s will result in a carbon alarm. The equipment should be stopped promptly to add carbon molecular sieve.
During operation, if a large amount of black dust is found spraying out from the silencer vent. The operation should be stopped immediately to investigate the cause and prevent exacerbation of carbon molecular sieve pulverization.
The storage, transportation, and handling of carbon molecular sieves are not harmful to humans. However, when filling carbon molecular sieves, it is advisable to wear protective goggles, respiratory filters, and use exhaust fans. After filling, the skin contact area should be washed with soap.
In case of alarms such as nitrogen purity, carbon level, and adsorption pressure drop, the cause should be promptly investigated and the fault eliminated.
During continuous operation, the airtightness of the connections at various pipeline joints should be checked frequently to ensure there are no air leaks.
Additionally, the operation status of pneumatic valves and freeze dryers should be checked regularly. Follow the maintenance instructions provided in the manuals or documents. Including the freeze dryers or adsorption dryers, cylinders, pneumatic valves, manual valves, flow meters, nitrogen analyzers, solenoid valves, regulating valves, pressure vessels, etc., to perform regular maintenance.
Nitrogen Generator Storage Conditions
Nitrogen generators should be stored in dry, clean, well-ventilated warehouses free from corrosive substances. For short-term outdoor storage and transportation, rain covers should be used, and the equipment should not directly contact the ground.
When the equipment is not in use for a long time or is shut down, the valves should be properly closed. Additionally, the equipment should be powered and ventilated for 1-2 hours every month to ensure that the equipment remains activated.
The above are the methods for maintaining a nitrogen generator.If you have any questions about the equipment. Please feel free to contact with the sales. Our company’s after-sales team will contact you promptly upon receiving notification！
