Small air separation unit assembly gauge tube should meet the following requirements: gauge tube should be degreased, and it is appropriate not to test pressure after assembly; gas gauge tube (such as pressure gauge tube) should not be in contact with cold equipment or cold tube, the distance should not be less than 2000 mm; liquid level gauge tube of the upper valve tube should be made from the container for 1/10. slope upward sloping to the valve, the lower valve tube from the container in the horizontal lead, in close to the wall of the cold box about 300 The lower valve pipe is led from the container horizontally and is bent into an omega shape to the valve within about 300 mm of the wall of the cooler (hot zone part).

 

The small air separation unit should meet the following requirements: the welding seam on the outer surface should be continuously welded and should not leak; the non-lead dip should not exceed 2/1000; the flange of the vertical liquefied gas pump should not exceed 1/1000 in its plane.

 

Dear Air Separation continues to develop new technologies for small air separation unit and large air separation unit, and applies strict requirements in all aspects of assembly units to ensure high quality units.

Small air separation unit is the unit that separates air into oxygen and other gases by first compressing and cooling the air into a liquid state and then using the characteristic that oxygen has a different boiling point to other gases in the air to obtain oxygen and liquid oxygen by evaporation and separation, as well as other rare gases as required.Liquid oxygen is produced using the cryogenic separation of air. The basic principle is to u...

The pressure relief of molecular sieve in the purification system is generally rapid in the early stage, not complete and running overtime in the later stage. The pressure relief degree is adjusted by the manual stop valve in front of the pressure relief valve. Through practical adjustment, no matter how it is adjusted, the pressure relief in front is fast, or the pressure can not be exhausted. It is suggested that the valve positioner should be added to the automatic pressure relief valve, and the pressure linear adjustment should be programmed, so that the impact on molecular sieve will be much smaller.
