What is the workflow of nitrogen compressor

Each nitrogen compressor is controlled with an industry standard on/off gauge control system with a control panel mounted on the side of the housing for easy operator access. All panels feature visual and audible alarms to warn operators of abnormal operation and automatically shut down in the event of packaging problems.

What is the workflow of nitrogen compressor?

The nitrogen compressor to separate the air is mainly composed of two adsorption towers filled with molecular sieves. Under normal temperature conditions, the compressed air is filtered, dewatered and dried, and then enters an adsorption tower, where the oxygen in the air is removed by the molecular sieve. The adsorbed nitrogen is enriched in the gas phase, flows out from the outlet and is stored in the nitrogen buffer tank, and the molecular sieve that has completed the adsorption in the other tower is rapidly depressurized, and the adsorbed components are resolved. The two towers circulate alternately, Inexpensive nitrogen gas with a purity of more than 99% can be obtained. The automatic switching of the valves of the entire nitrogen compressor system is automatically controlled by a computer.

Why perform regular maintenance on a nitrogen compressor?

For nitrogen compressor systems, regular maintenance of the compressor is highly recommended. A nitrogen compressor requires an annual preventive maintenance service to maintain output purity and integrity while extending the life of the generator.

What is the reason for the high suction pressure and high discharge pressure of nitrogen compressor?

1. Too much refrigerant. Excessive refrigerant will cause the suction pressure and exhaust pressure to be too high at the same time. This is because when too much refrigerant fills the accumulator, it will occupy a part of the condenser volume, reduce the heat dissipation area, and cause the condenser Poor condensation effect. It is sufficient to discharge excess refrigerant from the low pressure side.

2. The opening of the expansion valve is too large, which reduces the throttling effect, and the refrigerant cannot fully vaporize and absorb heat, causing the low pressure to rise, and liquid refrigerant flows back to the compressor, resulting in liquid shock. You can tighten the adjusting nut of the expansion valve by half a turn to two turns to adjust the low pressure within the normal range.

3. The suction valve of the nitrogen compressor is broken, so that the compressor cannot inhale the refrigerant gas in the evaporator, which will cause the low pressure to be too high. The compressor should be replaced at this time.

4. The inlet air temperature of the evaporator is too high. When the ambient temperature is high, the return air temperature of the evaporator will also be high, so that the low pressure will also increase. At this time, it is possible that the fresh air mechanism is broken, and the fresh air door cannot be closed after opening.
