Abstract
The utility model relates to an automatic control device of a nitrogen making machine. When the pressure of a nitrogen storage tank reaches to the rated high pressure, the automatic control system can make a nitrogen making system stop running, and simultaneously can enable an air compressor to be powered off and make the power failure of a cold dryer be delayed after the pressure of an air storage tank reaches to the rated high pressure; and when the pressure of the nitrogen storage tank reaches to the rated low pressure, the automatic control system can make the nitrogen making system start running, and simultaneously can enable the cold dryer to be powered on and the power on of the air compressor to be delayed after the pressure of the air storage tank reaches to the rated low pressure. As the automatic control device of the nitrogen making machine can enable the nitrogen making machine to stop running when the nitrogen demand quantity is not larger, unnecessary energy source waste and equipment abrasion are reduced, the running expense of the nitrogen making machine is greatly reduced, and the stability of the equipment is greatly improved.
