In recent years, industry research data has shown frequent technical issues caused by insufficient nitrogen purity, such as excessive fluctuations and molecular sieve failure. These issues not only result in a significant increase in energy consumption and a decline in product yield but also cause major economic losses due to equipment downtime. Confronted with the prominent challenges of high fixed asset investment and slow technical service response in traditional equipment maintenance models, FOOENS nitrogen generator rental services actively implement an innovation-driven development strategy. By building a flexible equipment resource allocation system and a full-process technical support framework, FOOENS provides industrial enterprises with a new approach to eliminate production bottlenecks and achieve cost reduction and efficiency improvement.

1. Fault Description

When a nitrogen generator operates with insufficient nitrogen purity, it directly impacts the stability of production processes and may even degrade product quality. The specific fault manifestations are as follows:

• Continuous deviation from the set value: For example, nitrogen purity drops from 99.9% to 99.4%, exceeding the process tolerance of 0.5%.
• Excessive fluctuation: Purity fluctuation exceeds 0.3% within 30 minutes (not meeting ISO 8573-1 Class 0 standards).
• System interlock anomalies: Peak pressure in the adsorption tower decreases by more than 15%, and regeneration cycles shorten by 20%-40%.

2. Causes of Formation

The root causes of insufficient nitrogen purity are often related to the degradation of key component performance or abnormal operating conditions:

• Reduced adsorption capacity of molecular sieves: Oil mist or moisture blocks molecular sieve micropores, lowering oxygen adsorption capacity.
• Inlet pressure fluctuations: When pressure disturbances exceed ±0.1 MPa for more than 10 minutes, the adsorption isotherm shifts, resulting in reduced actual processing capacity.
• Abnormal regeneration program: Insufficient regeneration temperature or overly short duration leads to incomplete desorption.
