At present, nitrogen production equipment has become a necessary equipment for many enterprises, but many workers only know how to operate, but do not know how to maintain the equipment.
Nitrogen generation equipment is mainly used in metal heat treatment process as protection gas, chemical industrial gas and various storage pipeline purification, as well as rubber, plastic products and other products in the production, but also can be used in the food industry for fresh packaging and emissions.
Of course, such a good product in the medical industry is also very good. Among them, purity, stability, pressure, flow rate are different. Can meet the needs of different customers.
For any machine, maintenance is very important, good maintenance can effectively extend the service life of nitrogen generator. In addition to maintenance, the correct use of nitrogen generator is also important to extend the life of the machine.
1. Turn off all power switches, including nitrogen generator, nitrogen inlet valve and sampling valve, until the system and pipeline are completely depressurized. Adjust the pressure of the pressure reducing valve to 1.0 bar, adjust the flow of the sampling flowmeter, and adjust the air volume to about 1. Pay attention that the air volume should not be too large, and start to test the purity of nitrogen.
2. When the pressure of compressed air is above 0.7 MPa, open the stop valve on the nitrogen generator and observe the pressure change on the absorption tank and whether the pneumatic valve works normally.
3. When the pressure of regeneration tower is zero, the pressure of two towers should be close to half of the original working tower pressure.
4. Close the whole system and all parts of the system. When the pressure of adsorption tank of nitrogen generator reaches about 0.6MPa, observe whether the nitrogen generation system works normally.
