1. The normal supply and normal opening and closing of the power supply, gas source and temperature conditions required by the quality ISO standard Chemical Nitrogen Plant and Nitrogen Generator; especially the stability of the power supply voltage, reduce the damage to the controller and solenoid valve caused by the power supply problem.
2. Pay attention to the pressure of the air storage tank at any time, and keep the pressure of the air storage tank between 0.6 and 0.8MPa, not lower than the rated value.
3. Check the automatic drainer daily to avoid blockage and loss of drainage. If it is blocked, open the manual valve slightly, close the self-draining valve, and then remove the automatic drain to disassemble and clean. When cleaning the auto drain, just use a soapy lather.

4. Check the three pressure gauges on the quality ISO standard Chemical Nitrogen Plant and Nitrogen Generator regularly, make a daily record of the pressure changes for equipment failure analysis, observe the flowmeter and nitrogen purity at any time, and keep the nitrogen purity of the outgoing gas.
5. Regularly check the refrigeration effect of the air dryer every week, so as to avoid the failure of the air dryer and the inflow of water into the nitrogen generator and the occurrence of carbon molecular sieve poisoning.
6. Operate and maintain the quality ISO standard Chemical Nitrogen Plant and Nitrogen Generator according to the requirements of the instrument use code, and check the sensitivity of the solenoid valve/pneumatic valve, the pressure range of the pressure regulating valve, the accuracy of the gas analyzer, the compression of the adsorption tower, and the exhaust condition of the muffler from time to time, the cleanliness of the inner tube of the flowmeter, etc.
