此款节能高压型制氮机为一体机系统。即内置全无油压缩机，经冷冻干燥机及三级过滤器除去油水、粉尘颗粒，经预处理后的无油干燥空气进入二组制氮吸附器进行氧氮分离，一级吸附，一组脱附，连续生产出合格的氮气送至氮气缓冲罐，当氮气缓冲罐压力达到设定压力时，停止制氮机组，切换至增压系统开始增压氮气，氮气缓冲罐压力下降到设定值时停止增压，又开始制氮运行，从而连续不断的产出高压氮气。氮气压力可高达1 .5MPa-30Mpa,。

该机型的运行状态为“全自动运行”（无需人为操作设备的启停），空气进品、氮气出口设有过滤调压部件，内置冷冻干燥机及C、T、A三级过滤器、自动排水器。PC控制系统选用西门子主机。氮气纯度由99.99 -99.999%氮气分析仪在线检测，氮气纯度不合格自动排空并报警，合格氮气输出后达到设定压力白动停机。节省空压机能耗达10%-30%不等。制氮吸附塔交替运行排空时，加装有快速排空装置，以达到制氮工艺快速脱附要求，延长了工艺电磁阀的使用寿命。

The energy-saving nitrogen making machine of high pressure uses an all-in-one system, that is, built-in oil-free compressor. Firstly, freezing and drying machine and three-stage filter are used to remove grease, dust particles. After preprocessed, the oil-free dry air is pushed into two groups of nitrogen adsorb machines to separate hydrogen and nitrogen. While one group adsorbing, the other group stripping, continuous qualified nitrogen is produced to nitrogen buffer tank. When nitrogen buffer tank's pressure reaches to set value, nitrogen generating unit stops and instead pressurization system starts charging nitrogen. When the nitrogen gas buffer tank pressure drops to the set point, it is supposed to stop charging and begin the operation of nitrogen making, thereby continuously outputting high pressure nitrogen whose pressure can be up to 1. 5 Mpa - 30 Mpa.

Running state of the machine is "automatic operation" (that is, without the need for operating the start-stop of the equipment). Air inlet and nitrogen outlet are equipped with pressure regulating components, the built-in refrigeration dryer and C, T, A three-stage filter and automatic drainage device. Siemens host is used in PC control system. Nitrogen purity is monitored by analyzer on-line, by 99.99-99.999% unit. Automatic emptying and alarm are set if the purity of nitrogen is unqualified, and the system will automatically stop when it reaches the set pressure after qualified nitrogen output, thus, saving the air compressor power consumption by up to 10-30% range. Altemately emptying system of nitrogen adsorption tower, with a rapid emptying device, in order to achieve rapid stripping requirements in nitrogen making process, prolongs the life of electromagnetic valve.

适用于航空、航天、原子能工业、军事等领域用氮，石油化工、矿井油田的安全用氮和工艺用氮等方面。

This machine is suitable for the aviation, aerospace, nuclear industry, military, the safety and process of the mine fields and petrochemical industry.
