People have invented countless things, which have brought great changes to people's work and life. Among them, people have also invented nitrogen production equipment, which can be used to produce nitrogen. But when people use it, they should not forget to do maintenance, so that the nitrogen production equipment can be used for a longer time and the possibility of failure is also reduced. However, people must pay attention to safety during maintenance and should not be careless. So what problems should people pay attention to when maintaining nitrogen production equipment?

1. When starting the nitrogen generation unit, the evacuation valve should be in the evacuation state to avoid overpressure of the air compressor.

2. No welding operation is allowed near the oil circuit system, and no pressure vessel can be modified by welding or other methods.

3. Before starting the machine, carefully check the whole nitrogen generation device to ensure that no tools, parts or other objects remain in the air compressor.

4. Regularly check the reliability of safety devices (such as safety valves).

5. When removing any pressure element, it is necessary to ensure that the whole system is in a pressure-free state.
