如何增加制氮機的使用時間？

一，制氮機，氮氣入口閥門和取樣閥關(guān)閉，然后關(guān)閉氮氣制造機的電源開關(guān)。等待系統(tǒng)和管網(wǎng)壓力的完全結(jié)束（廢氣從系統(tǒng)中富氧，注意消防安全，室內(nèi)空氣流通，打開）。調(diào)整采樣氧氣分析儀和減壓閥壓力調(diào)整到1.0條，調(diào)整采樣流量計，氣體將被分派到各地的1，注意采樣量不宜過大。開始測試氮氣純度。

1、 Close the nitrogen inlet valve and sampling valve of nitrogen generator, and then turn off the power switch of nitrogen generator. Wait for the complete end of the system and pipe network pressure (exhaust gas enriched from the system, pay attention to fire safety, indoor air circulation, open). Adjust the pressure of sampling oxygen analyzer and pressure reducing valve to 1.0, adjust the sampling flowmeter, and the gas will be distributed to 1 in different places. Pay attention to the sampling quantity should not be too large. Start testing nitrogen purity.

二，在壓縮空氣源壓力達到大于0.7兆帕，總進口截止閥，打開氮氣制造機，調(diào)整減壓閥將減少到約0.4至0.5兆帕的壓力，同時觀察吸附罐壓力的情況和是否能正常氣動閥的工作。

2、 When the pressure of compressed air source reaches more than 0.7 MPa, the total inlet stop valve, open the nitrogen manufacturing machine, adjust the pressure reducing valve to reduce the pressure to about 0.4-0.5 MPa, and observe the pressure of adsorption tank and whether the pneumatic valve can work normally.

三，然后順時針打開電控氮機電源開關(guān)的PLC主站系統(tǒng)。兩個吸附塔壓力變化觀察，確定兩個吸附塔是否正常開關(guān)。再生器的壓力為零時，一半的塔壓力應(yīng)接近原始工作甚至是兩個塔壓力。

3、 Then turn on the PLC master station system of the electric control nitrogen machine power switch clockwise. Observe the pressure change of two adsorption towers to determine whether the two adsorption towers are normally opened and closed. When the pressure of regenerator is zero, half of the tower pressure should be close to the original working pressure or even the pressure of two towers.

四，打開氧儀，電源開關(guān)，調(diào)節(jié)采樣流量適量，觀察氧含量。根據(jù)氮氣純度調(diào)節(jié)閥開口的需要，合格純度自動切換成氮氣貯罐，存儲氮氣壓力氮氣貯罐一般為0.6 0.8兆帕。

4、 Turn on the oxygen meter and power switch, adjust the sampling flow and observe the oxygen content. According to the need of opening the nitrogen purity regulating valve, the qualified purity is automatically switched to the nitrogen storage tank, and the nitrogen storage pressure is generally 0.60.8 MPa.

五，關(guān)閉整個系統(tǒng)和系統(tǒng)，在制氮機吸附罐壓力每部分為0.6兆帕，觀察制氮系統(tǒng)工作正常。

5、 Shut down the whole system and the system. When the pressure of each part of adsorption tank of nitrogen generator is 0.6 MPa, observe that the nitrogen generation system works normally.

六，慢慢打開空條目截止閥，流量調(diào)節(jié)至1/2的（醫(yī)院中央氧氣供應(yīng)系統(tǒng)）的額定流量。調(diào)節(jié)氮氣入口閥門開度來調(diào)節(jié)純度和流量的氮氣速率。

6、 Slowly open the empty entry stop valve and adjust the flow rate to 1 / 2 of the rated flow of the central oxygen supply system of the hospital. Adjust the opening of nitrogen inlet valve to adjust the nitrogen rate of purity and flow.

七，觀察氧米表示的氧含量是在符合要求。當?shù)獨饧兌冗_到，然后慢慢打開純天然氣出口截止閥，流量設(shè)定所需的流量，關(guān)閉空條目截止閥，當設(shè)備即可投入使用后正常運行。

7、 Observe the oxygen content indicated by the oxygen meter is in compliance with the requirements. When the purity of nitrogen reaches, slowly open the outlet stop valve of pure natural gas, set the required flow rate, and close the air entry stop valve. When the equipment can be put into use, it will run normally.
