The liquid nitrogen generator (liquid nitrogen machine) is composed of three parts: nitrogen generator (built-in or external), refrigeration equipment (gas liquefaction equipment) and Dewar tank. The whole machine has the function of automatic liquid replenishment with one key, and the equipment starts automatically when the liquid nitrogen in the liquid nitrogen tank is lower than the set liquid level. Liquid nitrogen machine manufacturing adopts the principle of mixed mass throttling refrigeration, cooling nitrogen from the ambient temperature to the saturation condensing temperature of nitrogen liquefaction step by step, the lowest temperature of refrigeration machine refrigeration can be up to -196 °, the liquid nitrogen liquefied in the refrigeration evaporator is transported to the liquid nitrogen tank to save the liquid nitrogen to obtain liquid nitrogen, the equipment automatically detects the liquid nitrogen level in the Dewar tank, and fully automatic control of the operation of the equipment.

The air enters the air compressor after removing dust and mechanical impurities through the air filter, compressing to the required pressure, and outputting clean compressed air after strict purification treatment of oil, water and dust removal, with the purpose of ensuring the service life of the molecular sieve in the adsorption tower. There are two adsorption towers with carbon molecular sieves, one tower works while the other tower is decompressed and desorbed. The clean air enters the working adsorption tower, passing through the molecular sieve when oxygen, carbon dioxide and water are adsorbed by it, the gas flowing to the exit end is nitrogen and trace amounts of argon and oxygen. Another tower (desorption tower) so that the adsorbed oxygen, carbon dioxide and water from the molecular sieve pores out of the discharge to the atmosphere. In this way, the two towers take turns to complete the separation of nitrogen and oxygen, continuous output of nitrogen, variable pressure (_bian4 ya1) adsorption nitrogen purity of 95%-99.9%, if you need a higher purity of nitrogen need to increase the nitrogen purification equipment. Variable pressure adsorption nitrogen machine output of 95%-99.9% nitrogen into the nitrogen purification equipment, while adding the appropriate amount of hydrogen through a flow meter, in the purification equipment in the oxygen removal tower hydrogen and nitrogen in the trace oxygen catalytic reaction to remove oxygen and then cooled by the water condenser, vapor separator to remove water, and then through the dryer depth drying removal.

The nitrogen liquefier adopts the principle of mixed mass throttling refrigeration to cool the nitrogen from ambient temperature to the saturation condensing temperature of nitrogen liquefaction step by step, and the lowest temperature of the refrigerator can reach 196°. The liquid nitrogen liquefied in the evaporator is transported to the liquid nitrogen tank to save the liquid nitrogen, and the equipment automatically detects the liquid nitrogen level in the Dewar tank and controls the operation of the equipment fully automatically.

The functioning of a small liquid nitrogen machine relies on the liquefaction process of nitrogen gas. The machine compresses the gas to a high pressure and cools it down with a heat exchanger, causing it to condense into liquid form that can be stored and utilized for various purposes.

Small liquid nitrogen machines are refrigeration units that work by compressing and cooling nitrogen gas. The gas is first drawn in and compressed, which raises its temperature. The compressed gas is then passed through a cooling system to reduce its temperature below the boiling point. This causes the gas to condense into a liquid state, which is collected in a storage vessel.

A small liquid nitrogen machine is an apparatus that converts nitrogen gas into its liquid state by compressing and cooling it. The compressed gas is first passed through a heat exchanger to remove excess heat and reduce its temperature before being fed into a liquefier. In the liquefier, the gas is cooled to a temperature below its boiling point to convert it into a liquid that can be stored and used for various applications.
