Automated Psa Type Nitrogen Generator , 75Nm3/Hr Nitrogen Making Machine

PSA industrial nitrogen gas generating machine used for laser cutting

1, Description of principle:

Pressure swing adsorption nitrogen production device takes clean compressed air as raw material, carbon molecular sieve as adsorbent, and USES pressure swing adsorption principle to obtain nitrogen at room temperature. According to the differences in the amount of oxygen and nitrogen adsorbed on the surface of carbon molecular sieve and the different diffusion rates of oxygen and nitrogen in carbon molecular sieve, the programmable controller controls the opening and closing of the program-controlled valve to realize the process of pressurized adsorption and decompression and desorption, complete the separation of oxygen and nitrogen, and obtain the required purity nitrogen. The whole nitrogen generator system is composed of: air compressor provides air source for nitrogen generator. Nitrogen is separated from the compressed air and concentrated in a low-pressure nitrogen storage tank. The nitrogen is then passed from the low-pressure nitrogen storage tank to the final high-pressure nitrogen storage tank through the high-pressure nitrogen pressurization device.

2,Product Feature:

• Nitrogen, as a high-pressure gas, can remove oxygen from the cutting area and assist laser cutting.This improves cutting quality, eliminates oxidation, and prevents discoloration, thereby increasing paint adhesion and welding strength. The laser cutting special nitrogen making machine produced by our company is equipped with skid-mounted and high integration, which can be used after debugging by professionals;
• Start and stop immediately. Under normal working conditions, the initial starting time is 1h and the second starting time is 0.5h.
• With different models, nitrogen production cost is low, which is 20-30% of liquid nitrogen cost in laser cutting industry.
• The device is equipped with a remote monitoring system. The operation parameters of the device can be monitored by mobile APP and computer WEB terminal.
• The equipment is equipped with energy monitoring and energy-saving adjustment, which can automatically adjust the operating parameters of the system within the range of 50-100% according to the actual gas consumption;
• Professional annual equipment maintenance plan and regular on-site inspection by professional staff ensure the long-term stable operation of nitrogen production system and eliminate the worries of users.
