制氮機(jī)儲氣罐安裝空壓機(jī)之后，不僅能儲存壓縮空氣，減少由于壓縮機(jī)排氣不連續(xù)產(chǎn)生的壓力脈動，實(shí)現(xiàn)供氣和用氣的平衡，而且能降低壓縮空氣的溫度，減少過過濾器和干燥劑的負(fù)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.

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.

制氮機(jī)由空壓機(jī)段、空氣預(yù)處理段及膜分離段三部分組成。分體組裝在礦用平板車上，三段之間以高壓膠管相連，從而構(gòu)成制氮裝置。吸附式制氮機(jī)以空氣為原料，以碳分子篩作為吸附劑，運(yùn)用變壓吸附原理，利用碳分子篩對氧和氮的選擇性吸附而使氮和氧分離的方法，通稱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.

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.

一般制氮機(jī)設(shè)備濾芯周期約為8000小時，或根據(jù)濾芯組差值表表明可更換濾芯。另一個極端的情況是濾芯組故障，導(dǎo)致空氣從空氣壓縮機(jī)直接排放到氮?dú)鈾C(jī)主機(jī)中，導(dǎo)致碳分子瞄準(zhǔn)或膜群中毒，當(dāng)?shù)募兌瓤隙〞陆禃r，基本上無法保存，只能更換主機(jī)設(shè)備或返回工廠檢查。 在正常溫度下，工業(yè)制氮機(jī)設(shè)備生產(chǎn)一般分為兩種模式，即可變壓力吸附氮和膜分離的氮生產(chǎn)。

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.
