The enterprise is more concerned about purchasing nitrogen generators. After using the nitrogen generator, the product can not achieve the expected effect. At this time, it depends on whether the flow and purity of the equipment meet the requirements of the production process. After the general equipment is produced, it will be debugged to meet the requirements, so the flow rate and purity will meet the requirements. However, if used for a long time, the purity may decrease.
Nitrogen generators usually use maintenance precautions:
1. Keep an eye on the pressure of the air storage tank and keep the pressure of the air storage tank between 0.7 and 0.75 MPa. Do not lower than the rated value.
2. Operate and protect according to the requirements of the instrument application code. Check the sensitivity of the solenoid valve/pneumatic valve, the pressure scale of the pressure regulator, the accuracy of the gas analyzer, the compression of the adsorption tower, and the exhaust of the muffler. , the degree of cleaning of the inner tube of the flow meter, and the like.
3. The normal supply of power, air supply and temperature conditions and normal opening and closing of the machine; especially the stability of the power supply voltage, reduce the damage to the controller and solenoid valve caused by the power supply.
4. Check the cooling fins of the dryer every week for cleanliness and avoid the effects of the dryer on the efficiency and life of the dryer.
5. The operator should observe the three pressure gauges on the machine on time and make a normal record of the pressure changes to prepare for the equipment fault analysis. The flowmeter and nitrogen purity should be investigated at any time, and the purity of the nitrogen gas has been adhered to.
6. Check the active drainer daily to avoid clogging and lose drainage. If it is blocked, open the manual valve slightly, close the self-discharge valve and then remove the active drain to disassemble and clean. When cleaning the active drain, use soap to clean. It is strictly forbidden to use aggressive solutions such as gasoline, toluene and pine perfume.
