Because the nitrogen generator is a long-term equipment, regular maintenance can not only prolong the service life of the equipment, but also greatly reduce the production cost of users. The purpose of nitrogen generator maintenance is to prevent faults rather than eliminate faults. When maintaining nitrogen generator equipment, users should replace it in time according to the running time of spare parts. Do not maintain blindly to avoid unnecessary losses.

一、空氣預處理系統

1、 Air pretreatment system

1、管道過(guò)濾器濾芯：每工作4000小時(shí)更換，或設備停滯超過(guò)6個(gè)月也須更換。

1. Filter element of pipeline filter: replace it every 4000 working hours or if the equipment stops for more than 6 months.

2、精過(guò)濾器濾芯：每工作4000小時(shí)更換，或設備停滯超過(guò)6個(gè)月也須更換。

2. Fine filter element: replace it every 4000 working hours or if the equipment stops for more than 6 months.

3、超精過(guò)濾器濾芯：每工作4000小時(shí)更換，或設備停滯超過(guò)6個(gè)月也須更換。

3. Ultra fine filter element: replace it every 4000 working hours or if the equipment stops for more than 6 months.

4、冷凍干燥機 ：a)、保持蒸發(fā)壓力（R22）0.4~0.5MPa之間。b)、建議加裝風(fēng)管，定期清潔冷卻器。c)、每日檢查自動(dòng)排水器，以免堵塞而失去排水作用。若堵塞時(shí)，可稍微打開(kāi)手動(dòng)閥門(mén)，關(guān)閉自排閥門(mén)再拆下自動(dòng)排水器，分 解清洗。清洗自動(dòng)排水器時(shí)，使用肥皂沫清洗即可。嚴禁使用汽油、甲苯、松香水等侵蝕性溶液。d)、每日檢查氣冷式冷凝冷卻器之鰭片是否干凈，以免因散熱不好影響干燥機之效用與壽命。e)、氣冷式：清洗冷凝冷卻器（抽取式）濾網(wǎng)可用壓縮空氣噴槍噴洗。若嚴重堵塞，可用清洗藥劑清洗，但不得使用會(huì )侵蝕銅管及鰭片之溶劑。

4. Freeze dryer: a) keep the evaporation pressure (R22) between 0.4 ~ 0.5MPa. b) It is recommended to install air duct and clean the cooler regularly. c) Check the automatic drainer every day to avoid blocking and losing the drainage function. If it is blocked, slightly open the manual valve, close the self drainage valve, and then remove the automatic drain for disassembly and cleaning. When cleaning the automatic drain, use soap foam to clean it. Strictly prohibit the use of gasoline, toluene, pine perfume and other corrosive solutions. d) Check whether the fins of the air-cooled condenser are clean every day to avoid affecting the utility and service life of the dryer due to poor heat dissipation. e) Air cooled: the filter screen of condensate cooler (extraction type) can be sprayed with compressed air spray gun. If it is seriously blocked, it can be cleaned with cleaning agent, but solvents that will corrode copper pipes and fins shall not be used.

水冷式干燥機：a)平時(shí)保持Y型水過(guò)濾器之清潔。b)必要時(shí)可拆開(kāi)端板，以加長(cháng)型軟毛刷清洗。c)或聯(lián)絡(luò )原廠(chǎng)服務(wù)部協(xié)助保養。f)隨時(shí)注意干燥機入口風(fēng)量、溫度及壓力是否超過(guò)額定。

Water cooled dryer: a) keep the Y-type water filter clean at ordinary times. b) If necessary, the end plate can be disassembled for cleaning with extended soft bristle brush. c) Or contact the original service department to assist in maintenance. f) Always pay attention to whether the air volume, temperature and pressure at the inlet of the dryer exceed the rated value.

5、活性炭：每12個(gè)月更換。

5. Activated carbon: replace every 12 months.

6、自動(dòng)排污閥：運行時(shí)要注意觀(guān)察，如出現排污不正?，F象要及時(shí)清洗或更換。

6. Automatic blowdown valve: pay attention to observation during operation. In case of abnormal blowdown, clean or replace it in time.

二、氧氮分離系統

2、 Oxygen nitrogen separation system

1、電磁閥：壽命約為2年。

1. Solenoid valve: the service life is about 2 years.

2、氧傳感器：不同分析儀表的傳感器使用壽命不一樣，一般為一年或一年半。

2. Oxygen sensor: the service life of sensors of different analytical instruments is different, generally one year or one and a half years.

3、氣動(dòng)閥門(mén)密封件：壽命約為2年，使用壽命為150萬(wàn)次，為確保設備正常運行，建議用戶(hù)一年更換。

3. Pneumatic valve seal: the service life is about 2 years and the service life is 1.5 million times. In order to ensure the normal operation of the equipment, it is recommended that the user replace it in one year.

4、粉塵過(guò)濾器濾芯：每18個(gè)月更換，每次加篩后更換。

4. Dust filter element: replace it every 18 months, and replace it after screening each time.

5、分子篩：氣缸報警后添加，根據用戶(hù)使用情況，建議用戶(hù)一年添加一次。

5. Molecular sieve: added after the cylinder alarm. According to the user's use, it is recommended that the user add it once a year.
