(1) The base of the two supports must be on the same level, ensuring that the 4 mark lines on the outside of the vessel's simplified orientation at both ends are level
(2) Horizontal adsorber movable support: after the installation level is adjusted, the first nut on the support is tightened and then backed up one turn, then locked with the second nut
(3) After the horizontal adsorber is in place, the level of its internal orifice plate <10mm is tested to confirm the level of the marker bar...
When the air separation unit is in normal operation, the liquid flows down and can only flow on the tray and flow to the lower tray through the overflow bucket because the supporting force of the rising steam prevents the liquid from flowing down from the small hole of the tray. After shutdown, due to the interruption of rising gas flow, the liquid on the tray can flow from the overflow bucket to the lower tray, and also can flow through the small hole on the tray to the lower tray. This will cause the surface of liquid oxygen and liquid air rise, which may exceed the position of the expansion air outlet pipe, resulting in liquid carrying accident of the expander during restart. Therefore, pay attention to the liquid level position when stopping.
