Product Features:

1. The raw air is taken from nature, and nitrogen can be produced only by providing compressed air

and power supply. The equipment has low energy consumption and low operation cost.

2. The purity of nitrogen can be adjusted easily. The purity of nitrogen is only affected by the amount

of nitrogen exhaust. The purity of common nitrogen can be adjusted between 95% and 99.99%; The

high purity nitrogen generator can be adjusted between 99% and 9.999%9.

3. The equipment has high degree of automation, fast gas production and can be unattended. Start,

shut down just press the button, start within 10-15 minutes can produce nitrogen.

4. The equipment has the advantages of simple process, compact structure, small floor area and

strong adaptability.

5. The molecular sieve was loaded by Blizzard method to avoid the pulverization of molecular sieve

caused by high-pressure air impact, and the molecular sieve was used for a long time.

6. Digital flowmeter with pressure compensation, high precision industrial process monitoring sec-

ondary instrument, with instantaneous flow and cumulative calculation function.

Principle and process of oxygen cutting

Oxygen cutting of steel uses a gas flame (called preheating flame) to heat the surface layer of steel to the ignition point and form an activated state, and then feeds high-purity, high-flow rate cutting oxygen so that the iron in the steel burns in the oxygen atmosphere to generate iron oxide slag while releasing a large amount of heat, with the help of these combustion heat and slag constantly heating the lower layer of steel and the leading edge of the kerf so that it also reaches the ignition point, up to the bottom of the workpiece. At the same time, the momentum of the cutting oxygen flow blows the slag away, thus forming a kerf to cut through the steel. Thus, in macro terms, oxygen cutting is a combination of the chemical process of burning iron (broadly speaking, metal) in high purity oxygen in steel and the physical process of removing slag by the flow of cutting oxygen.

The entire oxygen cutting process can be divided into four interrelated stages.

1. The metal surface at the starting point is heated to its ignition point with a preheating flame, and the combustion reaction in the cutting oxygen then begins.

2. The combustion reaction propagates to the lower layers of the metal.

3. Exclude the slag generated by the combustion reaction and cut the metal along the thickness direction.

4. Use the slag and the heat of the preheating flame to heat the upper layer of the metal at the front edge of the cut to the ignition point, so that it continues to produce combustion reactions with oxygen.

The above process is repeated continuously, and the metal cutting is carried out continuously.
