PSA Nitrogen Generator is widely used in many industries, which is an excellent nitrogen making equipment. It mainly undertakes the principle of PSA and directly obtains nitrogen from compressed air. But many customs may find that the purity of PSA Nitrogen Generator will decrease after operating for a long time. What is the reason? Let’s take a check.
At present, PSA Nitrogen Generator purity decrease could be mainly divided into three reasons:
1. Excessive Flow
The original purity and flow rate of PSA Nitrogen Generator are customized, the purity will decrease if the flow rate is increased, and the purity will increase if the flow rate is reduced. It is suggested that the flow rate should not be adjusted according to the professional instruction.
2. Expiration of Carbon Molecular Sieve
If the PSA Nitrogen Generator is used for a long time, the quality of the carbon molecular sieve will deteriorate, and the purity of nitrogen will decrease. The carbon molecular sieve needs to be replaced now, and the purity can be restored after replacing.
After PSA Nitrogen Generator operation for a certain years, maintenance is needed. Many customers report that gas production is insufficient, the purity is reduced, and the silencer powder spraying of the nitrogen generator occurs.
3. Solenoid Valve Failure
Solenoid valve is the main part of adsorption control, solenoid valve failure can lead to insufficient gas production, purity decline and so on.
The above is the main factor of PSA Nitrogen Generator purity decline, customer could check according to it when purity decline.
