What are the technical requirements for the installation of heat exchanger units?

1. Technical requirements for hoisting. The hoisting department should prepare all the rigging of the machine, and carefully do the introspection task according to the safety rules. For large heat exchanger units, because of the large diameter, large number of heat exchange tubes and high lifting quality, the lifting binding should be selected at the reinforced pad of the shell support, and wooden blocks should be set on both sides of the shell to maintain the shell, so as to prevent the shell from being crushed and damaged by plastic deformation caused by wire rope during lifting.

2. The size of the device deviates from the requirements. Whether the deviation of each local size of the heat exchanger unit can meet the requirements of the specification should be reflected.

3. Requirements of bearing device. The sliding plate should be embedded on one side of the movable support on the bottom, and both sides of the anchor bolt are provided with pads. Leveling equipment At present, the inclined pad iron can be welded to the base plate of the heat exchanger unit, but not to the flat pad iron or slide plate above, and the pad iron must be lubricated and leveled to ensure the free expansion and contraction of the movable support.

4. Fastening of bolts. The fastening of heat exchanger bolts should be stopped at most three times, and the driving ends of each time should be staggered by 120. The fastening sequence is as shown in the circular diagram.
