99.999% purity industrial PSA nitrogen generator provides comprehensive nitrogen gas solutions for laser cutting equipment

99.999%  purity  industrial  PSA nitrogen generator provides comprehensive nitrogen gas solutions for  laser cutting equipment

• Purity: Nitrogen gas used in laser cutting usually needs to be of high purity. Usually the purity of nitrogen is required to reach 99.99% or higher to ensure that there are no impurities or bad gases during the cutting process. High-purity nitrogen can help improve cut quality and reduce oxidation on the material surface.


• Pressure: Nitrogen pressure depends on specific cutting equipment and materials. In general, the nitrogen pressure used in laser cutting is usually between 6 and 20 bar (87 and 290 psi). The exact pressure setting should be adjusted according to the requirements of the cutting machine and material.


• Gas Flow: In addition to purity and pressure, gas flow is also a factor to be aware of. Proper gas flow can help to effectively remove molten metal and waste from the cutting area, thereby improving cutting results. The gas flow setting should be adjusted according to the specific cutting parameters and material type.


• Safety precautions: When using nitrogen for laser cutting, you need to pay attention to the following safety precautions:


• Ensure the safety of gas cylinders and gas supply systems, following relevant safety practices and regulations.
  Avoid nitrogen leakage during operation and ensure that the operating environment is well ventilated.
  Regular inspection and maintenance of cutting equipment and gas supply systems to ensure their proper functioning and safety.

1. Operational Principle

PSA nitrogen generation adopts a carbon molecular sieve as an adsorbent whose capacity of adsorbing the oxygen in the air shall be larger than that of adsorbing the nitrogen in the air. By means of a valve opened and closed with PLC, two columns a&b can be shifted in circulation for pressured adsorption,de-pressured dis-adsorption in turn so as to separate the oxygen and nitrogen in the air, thus a nitrogen gas with purity demanded can be made.

Food industry: Equipped with LJ sterilizing filter, which can be used for nitrogen-filled packaging, grain storage, fresh-keeping of vegetables and fruits, and wine sealing and preservation.
Coal industry: underground explosion-proof and coalfield fire-fighting and extinguishing.
Chemical industry: nitrogen blanketing, replacement, cleaning, pressure conveying, chemical reaction agitation, chemical fiber production protection, etc.
Petroleum and natural gas industry: petroleum refining, nitrogen-filled purge and leak detection of containers and pipelines, and oil extraction by nitrogen injection.
Pharmaceutical industry: Nitrogen-filled storage of Chinese and Western medicines, pneumatic conveying of nitrogen-filled medicines, etc.
Others: metallurgical industry, rubber industry, aerospace industry, etc...

Nitrogen gas is generally used in two key areas in conjunction with laser technology applications

1) As a blanketing or “assist” gas

Oxidization of certain materials can be a very undesirable problem caused by the application of heat in the presence of oxygen. It can produce discoloration and cause a carbon layer to form on the cut edge.
This can affect the appearance of the finished product or cause a lack of adhesion for any coating
or paint finish on the oxidized surface.

Due to its inert properties, nitrogen gas prevents oxidization of the cut edge by allowing the laser to operate in an oxygen-free environment. The nitrogen gas pressure is also used to clear the cut, by blowing away the molten material. This produces a clean edge without any residual material sticking to the underside of the material (sometimes referred to as ‘dross’).

2) To purge the path, the laser beam travels along to the target area.

On many laser-generating machines, the beam is produced in one section and has to be directed to the point of use in another section. The laser beam is generally contained within hollow, sometimes telescopic, tubes and flexible bellows and is focused and reflected by various lenses and mirrors to the target area. To prevent the beam from distorting and to maintain power and intensity, the beam path needs to be kept clear of dirt particulate and any other contaminants that could cause it to diverge or lose power.

The lenses and water-cooled mirrors also need to be kept free of dirt, condensing hydrocarbons, and water vapor that could otherwise cause the burning and marking of these expensive components. Nitrogen is the ideal medium to use for beam guideway purging as it is dry, clean, oil-free, and has a very low contaminating content.
