Nitrogen generator maintenance and nitrogen generator maintenance are two different concepts, maintenance is because the equipment has not been regularly maintained and the repair means are taken, the maintenance cost of nitrogen generator is much greater than the maintenance of nitrogen generator, most users can do regular maintenance of nitrogen generator system, although it costs part of the cost, but to ensure that the nitrogen generator part is stable and reliable. Next, I will take stock of the failures caused by the nitrogen generator system not being maintained!
First of all, the air compressor part, regular replacement of oil filter manufacturers can do, but some air compressor maintenance will appear after a large amount of lubricating oil flying out, air compressor flying oil, oil running is because the air compressor maintenance inspection is not in place is often found problems, but also lead to the failure of the back-end air purification components, nitrogen generator adsorbent failure is the main reason.
Part of the function of air purification is to filter the moisture in the compressed air and then remove it from the system, and the most common problem is because the drainage system fails, not because the filter and desiccant are not replaced regularly. The failure of the freeze-desiccant automatic drainage system will cause the inside of the refrigeration dryer to freeze, block the pipes, and greatly reduce the system pressure, the most serious is that the moisture in the compressed air enters the adsorption tower of the nitrogen generator, affecting the performance of the nitrogen generator.
The nitrogen generator part includes general nitrogen and high-purity nitrogen purification, the general nitrogen part of the aerobic nitrogen analyzer is the most ignored by users, the nitrogen generator silencer ash spraying, water spraying, nitrogen purity has not been up, the low working pressure of the nitrogen generator seriously affects the normal use of the nitrogen generator, high-purity nitrogen purification is divided into hydrogenation and deoxygenation, carbon deoxygenation two kinds, ** high, high oxygen content, deaerator temperature exceeds the normal set value, deaeration tower burn-through and other serious faults need to be repaired in time to put into use,
