- The volume of nitrogen gas is relatively large. In order to facilitate storage and transportation, the gas is usually compressed into liquid and stored in a cylinder. This is how nitrogen is processed. To compress nitrogen, a nitrogen compressor is used. For different needs, this This kind of equipment has also derived a variety of different models, their classification basis is as follows:
1. Classification according to the output pressure of the nitrogen compressor:
Low pressure air compressor: 0.2-1.0Mpa)
Medium pressure air compressor: 1.0-10Mpa,
High pressure air compressor: 10-100Mpa
Ultra high pressure air compressor: above 100Mpa
2. Classification according to the output flow (discharge volume) of the nitrogen compressor:
1. Mini, small nitrogen compressor: 0.1-60m3/h)
2.Medium air compressor: 60-1200m3/h)
3. Large air compressor: ≥1200m3/h
3. According to the type of cooler, it can be divided into water-cooled and air-cooled compressors. The water-cooled type adopts cooling water open circulation cooling, and the air-cooled type adopts fan cooling.
4. According to different engines, it can be divided into electric motor drive mode and diesel engine drive mode. The large electric type is equipped with a power distribution cabinet, and the diesel-driven type is started by a battery. Both compressors have direct connection and belt drive.
5. According to the lubrication method, it can be divided into oil-free and oil-lubricated compressors. The latter is divided into splash type and forced type (that is, oil pump and oiler lubrication type).
6. According to the basic configuration of the compressor, it can be divided into fixed type (basic type, no basic type) and mobile air compressor.
7. Classified according to working principle, it can be divided into volume type air compressor and speed type air compressor.

7. Classified according to working principle, it can be divided into volume type air compressor and speed type air compressor.
The working principle of a nitrogen compressor is to compress the gas volume in nitrogen, so that the velocity of air molecules per unit volume increases, thereby increasing the kinetic energy of the gas, and then increasing the kinetic energy. The gas molecules are converted into pressure energy to increase the pressure of the compressed gas. Commonly used are reciprocating type (piston type, diaphragm type), rotary type (sliding type, screw type).
High-speed nitrogen compressors such as centrifugal compressors, axial flow, mixed flow, through the energy conversion of the rotating turbine, the rotor realizes the above conversion by changing the kinetic energy and pressure of the gas. The fixed diffuser reduces the flow rate of the air to realize the change of kinetic energy and pressure.
The classification of nitrogen compressors is explained from the above seven points.
