The volume of nitrogen gas is relatively large. In order to facilitate storage and transportation, the gas is usually compressed into a liquid and stored in a steel cylinder. Nitrogen is treated in this way. To compress nitrogen, a nitrogen compressor is used. For different needs, this equipment has also derived various models, and their classification basis is as follows:
氮气气体的体积是比较大，为了便于存储运输，通常都是将气体压缩成液体存储于钢瓶中，氮气就是这样处理的，要压缩氮气，就会用到氮气压缩机，针对不同的需求，这种设备还衍生出了各种不同的型号，它们的分类依据如下：
1、 Classification by nitrogen compressor output pressure:

1、按氮气压缩机输出压力分类：
Low pressure air compressor: 0.2-1.0Mpa)
- 低压空压机:0.2一1.0Mpa)
Medium pressure air compressor: 1.0-10Mpa,
- 中压空压机:1.0-10Mpa，
High pressure air compressor: 10-100Mpa
- 高压空压机:10-100Mpa
Ultra high pressure air compressor: above 100Mpa
- 超高压空压机:100Mpa以上
2、 Classified by nitrogen compressor output flow rate (displacement):
二、按氮气压缩机输出流量(排气量)分类:
1. Micro and small nitrogen compressors: 0.1-60m3/h)
1、微型、小型氮气压缩机:0.1一60m³/h)
2. Medium air compressor: 60-1200m3/h)
2、中型空压机:60-1200m³/h)
3. Large air compressor: ≥ 1200m3/h
3、大型空压机:≥1200m³/h
3、 According to the cooling method, it can be divided into water-cooled and air-cooled compressors. The water-cooled type adopts open circulation cooling with cooling water, while the air-cooled type adopts fan cooling.
三、按冷却器方式可分为水冷式和风冷式压缩机。水冷式采用冷却水开式循环冷却，风冷式采用风扇冷却。
4、 According to different engines, it can be divided into electric motor drive mode and diesel engine drive mode. Air compressors. The large electric type is equipped with a power distribution cabinet, and the diesel driven type is started by an electric battery. Both types of compressors are directly connected and belt driven.
四、按发动机的不同可分为电动机驱动方式和柴油机驱动方式空压机。大型电动式配有配电柜，柴油驱动式由电瓶启动，两种压缩机均有直联和皮带传动。
5、 According to the lubrication method, it can be divided into oil-free lubrication and oil-lubricated compressors, and the latter is further divided into splash type and forced type (i.e. oil pump and injector oil supply lubrication).
五、按润滑方式可分为无油润滑和有油润滑压缩机，后一种又分为飞溅式和强制式(即油泵和注油器供油润滑式)。
6、 According to the basic configuration of the compressor, it can be divided into fixed (with or without foundation) and mobile air compressors.
六、按压缩机基础配置可分为固定式(有基础式、无基础式)和移动式空压机。
7、 According to the working principle, it can be divided into volumetric air compressors and velocity air compressors.
七、按工作原理分类，可分为容积型空压机和速度型空压机。
The working principle of a nitrogen compressor is to compress the volume of gas in nitrogen, increasing the velocity of air molecules per unit volume, thereby increasing the kinetic energy of the gas, and then increasing the kinetic energy. Gas molecules are converted into pressure energy to increase the pressure of compressed gas. Commonly used are reciprocating (piston type, diaphragm type) and rotary (sliding type, screw type).
氮气压缩机的工作原理是压缩氮气中的气体体积，使单位体积中空气分子的速度增加，从而增加气体的动能，然后增加动能。气体分子转换成压力能量以增加压缩气体压力。常用的有往复式(活塞式，隔膜式)，旋转式(滑动式，螺旋式)。
High speed nitrogen compressors, such as centrifugal compressors, axial flow, and mixed flow, convert energy through a rotating turbine, and the rotor achieves the above conversion by changing the kinetic energy and pressure of the gas. Reduce the flow rate of air through a fixed diffuser to achieve changes in kinetic energy and pressure.
高速氮气压缩机如离心压缩机，轴流，混流，通过旋转涡轮机的能量转换，转子通过改变气体的动能和压力实现上述转换。通过固定的扩散器降低空气的流速来实现动能与压力的变化。
