Nitrogen is an inert gas and is widely present in the atmosphere. It is a relatively inexpensive gas, so it is widely used in the national economy such as laser cutting, chemical protective gas, chemical synthesis, electronics industry, pharmaceutical industry, etc.
The following examples illustrate the application of nitrogen compressors in the nitrogen industry.
Nitrogen acts as a protective gas in laser cutting. Medium-pressure nitrogen is mainly used to blow off oxygen to prevent oxidation of metal incisions and surrounding areas at high temperatures during cutting, thus avoiding the appearance of brown oxidized spots.
Achieve smooth cutting surface, no burr and no dross effect
Generally, the pressure of nitrogen required for laser cutting is 15-40 barg, and the nitrogen from the PSA nitrogen generator is 10 barg.
Therefore, a nitrogen compressor is required to pressurize the nitrogen, and the nitrogen pressure is referred to the pressure required for laser cutting.
Generally, the nitrogen pressure of the PSA nitrogen generator is not high. If the capacity of the nitrogen generator is excessive, or if the peak and valley electricity is used for filling at night, it is more economical. It is necessary to store the nitrogen for later use. It is pressurized with a nitrogen compressor to a pressure of 200-300 kg and filled into a high-pressure bottle. A high-pressure bottle can be filled with about 10 cubic meters of nitrogen.
Generally, the nitrogen pressure of the PSA nitrogen generator is not high. If the nitrogen production machine has excess capacity, or if it is filled with peak-to-peak power at night, there is more economic benefit. It is necessary to store nitrogen for subsequent use. At this time, a nitrogen compressor booster is generally used. Filled into a high pressure bottle at a pressure of 200-300 kg, a high pressure bottle can be filled with about 10 cubic meters of nitrogen.
