Nitrogen compressor refers to the compressor used to pressurize nitrogen and realize transportation or storage
Nitrogen compressor has many applications in national economy
for example
1. Laser cutting
Nitrogen plays the role of protective gas in laser cutting. Medium pressure nitrogen is mainly used to blow away oxygen, prevent oxidation of metal incision and surrounding under high temperature, and improve the cleanliness and beauty of cutting surface
2. Nitrogen storage
Generally, the outlet pressure of PSA nitrogen generator is less than or equal to 10 barg. If the nitrogen generator has excess capacity, or if it is filled at night with peak valley power, it is more economical. It is necessary to store the nitrogen for subsequent use. At this time, the nitrogen compressor is generally used to pressurize the pressure to 200-300 kg and fill it into the high-pressure bottle. Generally, a high-pressure bottle can fill about 10 cubic meters of nitrogen
The oil-free lubricated reciprocating plug nitrogen compressor has two cooling modes: air cooling and water cooling. It can be divided into single action and double action structures, vertical and angle types, medium pressure and high pressure. The wind brand series oil-free lubricated nitrogen compressor has excellent performance, smooth operation, high efficiency and energy saving, long service life, and is widely used in nitrogen laser cutting, nitrogen canning, chemical industry, etc.
The friction pairs of Bailian nitrogen compressor manufacturers this series of oil-free nitrogen compressors participating in gas compression are not lubricated with thin oil. The friction seals such as piston ring and guide ring are made of special materials with self-lubricating performance. The structural advantages are as follows:
1. There is no thin oil lubrication in the whole nitrogen compression system, which avoids the possibility of oil contacting with high-pressure and high-purity nitrogen (the vertical nitrogen compressor is not completely oil-free type);
2. The whole nitrogen compressor system has the advantages of simple structure, convenient control and easy operation;
3. Nitrogen, the gas medium to be compressed, has no pollution, and the purity of nitrogen at the inlet and outlet of the compressor is the same.
