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(yù)處理系統(tǒng)

1、 Air pretreatment system

1、管道過濾器濾芯：每工作4000小時更換，或設(shè)備停滯超過6個月也須更換。

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

2、精過濾器濾芯：每工作4000小時更換，或設(shè)備停滯超過6個月也須更換。

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

3、超精過濾器濾芯：每工作4000小時更換，或設(shè)備停滯超過6個月也須更換。

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)、建議加裝風管，定期清潔冷卻器。c)、每日檢查自動排水器，以免堵塞而失去排水作用。若堵塞時，可稍微打開手動閥門，關(guān)閉自排閥門再拆下自動排水器，分 解清洗。清洗自動排水器時，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)平時保持Y型水過濾器之清潔。b)必要時可拆開端板，以加長型軟毛刷清洗。c)或聯(lián)絡(luò)原廠服務(wù)部協(xié)助保養(yǎng)。f)隨時注意干燥機入口風量、溫度及壓力是否超過額定。

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個月更換。

5. Activated carbon: replace every 12 months.

6、自動排污閥：運行時要注意觀察，如出現(xiàn)排污不正常現(xiàn)象要及時清洗或更換。

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(tǒng)

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、氣動閥門密封件：壽命約為2年，使用壽命為150萬次，為確保設(shè)備正常運行，建議用戶一年更換。

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、粉塵過濾器濾芯：每18個月更換，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(jù)用戶使用情況，建議用戶一年添加一次。

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.
