The raw air is compressed to about 0.52Mpa by the air compressor after filtering out dust and impurities, and then cooled to about 10℃ by the refrigerant glycol aqueous solution or Freon, and then enters the purification system to purify and remove water, carbon dioxide and other impurities in the air. Part of the raw material air enters the lower tower via the second raw material air pipeline, another part is liquefied into liquid air via the liquefier and enters the lower tower via the liquid air separation plant  pipeline, where the thermal mass is cross-condensed and evaporated, and the nitrogen, liquid nitrogen, dirty liquid nitrogen, poor liquid air and oxygen-rich liquid air are obtained in the lower tower in turn by the separation of the multi-layer tower plates.

Dear Air's high quality small air spearation unit, large air spearation unit and liquid air spearation plant have won the trust of customers at home and abroad.

Due to improper adjustment of seal gas pressure during operation, liquid oxygen pump can not pump liquid or leak.   From the quality point of view, when the sealing pressure is too high, there will be gas leakage into the pump through the labyrinth seal, resulting in the impeller with gas or even idling, resulting in liquid injection or pressure drop; when the air pressure before sealing is too low, there will be liquid oxygen leakage.   From the quantity point of view, when (p1-p3...
