制氮机由空压机段、空气预处理段及膜分离段三部分组成

制氮机储气罐安装空压机之后，不仅能储存压缩空气，减少由于压缩机排气不连续产生的压力脉动，实现供气和用气的平衡，而且能降低压缩空气的温度，减少过过滤器和干燥剂的负荷。

After the air compressor is installed in the air storage tank of the nitrogen generator, it can not only store compressed air, reduce the pressure pulsation caused by the discontinuous discharge of the compressor, realize the balance of gas supply and gas consumption, but also reduce the temperature of compressed air and the load of filter and desiccant.

对现代军用飞机而言,燃油系统火灾是普遍 也是严重的潜在危险,提高燃油箱的生存力对于 提高整机的生存力具有重大意义。机载制氮机系统把引自发动机压气机的高压气体处理成 适合油箱惰化的氧浓度较低的富氮气体,通入燃油箱。山东制氮机

For modern military aircraft, fuel system fire is a common and serious potential danger. Improving the survivability of fuel tank is of great significance to improve the survivability of the whole aircraft. The high-pressure gas from the engine compressor is processed into nitrogen rich gas with low oxygen concentration suitable for inerting of fuel tank, which is passed into the fuel tank.

制氮机由空压机段、空气预处理段及膜分离段三部分组成。分体组装在矿用平板车上，三段之间以高压胶管相连，从而构成制氮装置。吸附式制氮机以空气为原料，以碳分子筛作为吸附剂，运用变压吸附原理，利用碳分子筛对氧和氮的选择性吸附而使氮和氧分离的方法，通称PSA制氮。

The nitrogen generator consists of air compressor section, air pretreatment section and membrane separation section. The three sections are connected by high-pressure rubber tubes to form a nitrogen making device. Adsorption type nitrogen generator uses air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption principle, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen, which is generally known as PSA nitrogen production.

制氮机是按变压吸附技术设计、制造的氮气设备。制氮机以进口碳分子筛为吸附剂，采用常温下变压吸附原理分离空气制取高纯度的氮气。

Nitrogen generator is designed and manufactured according to pressure swing adsorption technology. High quality imported carbon molecular sieve is used as adsorbent in the nitrogen generator, and the principle of pressure swing adsorption at room temperature is used to separate air to produce high purity nitrogen.

一般制氮机设备滤芯周期约为8000小时，或根据滤芯组差值表表明可更换滤芯。另一个极端的情况是滤芯组故障，导致空气从空气压缩机直接排放到氮气机主机中，导致碳分子瞄准或膜群中毒，当氮的纯度肯定会下降时，基本上无法保存，只能更换主机设备或返回工厂检查。 在正常温度下，工业制氮机设备生产一般分为两种模式，即可变压力吸附氮和膜分离的氮生产。

Generally, the filter element cycle of nitrogen generator equipment is about 8000 hours, or the filter element can be replaced according to the difference table of filter element group. The other extreme case is the failure of filter element group, which leads to the direct discharge of air from the air compressor to the main engine of nitrogen machine, resulting in carbon molecule aiming or membrane group poisoning. When the purity of nitrogen is sure to decline, it is basically unable to save, so the main equipment can only be replaced or returned to the factory for inspection. At normal temperature, the production of industrial nitrogen generator equipment is generally divided into two modes, namely nitrogen production by variable pressure adsorption and nitrogen production by membrane separation.
