The 30bar high-pressure nitrogen generator is special supporting equipment for laser cutting processing, which provides high-pressure and high-purity nitrogen auxiliary gas for fiber laser cutting, carbon dioxide laser cutting and other equipment, and is an essential device to improve the cutting quality of metal materials. In laser cutting process, high-pressure nitrogen acts as protective gas and blowing gas, which can isolate air oxidation, prevent metal cutting section from generating oxide layer, and blow away molten metal residue rapidly, making the cutting surface smooth and flat without burrs. Different from ordinary low-pressure nitrogen generators, this equipment is optimized and upgraded in pressure resistance, gas compression system and purification structure to stably output nitrogen with pressure up to 30bar and purity above 99.9%.

The core system of the high-pressure nitrogen generator consists of primary PSA nitrogen production module and secondary high-pressure compression module. The primary PSA system completes air separation to produce high-purity low-pressure nitrogen, and then the nitrogen is sent to the high-pressure piston compressor for secondary pressure boosting, which steadily increases the gas pressure from 0.8bar to 30bar required for laser cutting. The equipment is equipped with a multi-stage pressure stabilization and buffer system, which can eliminate pressure fluctuation in the compression process, ensure that the output nitrogen pressure is stable within ±0.5bar, and avoid cutting defects such as uneven cutting seam and edge collapse caused by unstable air pressure. At the same time, the high-precision filtration and drying module is configured to control the gas dew point strictly below -55℃, ensuring no water and oil impurities in the high-pressure nitrogen.

In terms of industrial application advantages, the 30bar high-pressure integrated nitrogen generator replaces the traditional bottled nitrogen and liquid nitrogen gas supply mode, greatly reducing the production cost of laser cutting enterprises. The equipment can realize 24-hour continuous self-produced nitrogen, with fast gas production speed and stable performance, which can perfectly match the continuous operation rhythm of laser cutting equipment. For different metal cutting scenarios such as stainless steel, carbon steel, aluminum alloy and copper, the high-pressure high-purity nitrogen provided by the equipment can effectively improve the cutting precision and finished product rate, and the fully automatic intelligent control system can realize unattended operation, reducing manual operation cost and improving the overall production efficiency of the workshop.
