The influence of the sun’s direction during the alignment of the tower structure
Thread Content
While reading the book \"Application of Technical Methods in the Installation of Chemical Engineering Machinery and Equipment\", there is a section on the installation of towers that states: \"For vertical equipment with a height of over 20 meters, alignment should be carried out on overcast days when the wind speed is no more than level 4, in order to avoid the effects of sunlight and wind on its verticality.\" I understand the issue of strong winds, but “overcast weather”. . . To avoid the direction of sunlight. . . “It affects the plumbness.” I would like to ask everyone, how should this be understood? Thank you for your advice!
I’m not sure about this either; I wonder if it’s the temperature differences between the shaded and exposed sides caused by sunlight that lead to variations in metal deformation ;P
When alignment is done on a sunny day, there is a significant temperature difference between the sunny side and the shaded side of the tower, and this is true even in winter. An excessively tall tower can affect its verticality
I can’t figure it out; I still need someone who knows how to do installations to guide me
I really didn’t expect this – can the temperature differences caused by winter sunlight also be enough to cause the equipment to bend?
Just as there is a difference in temperature between the north and south sides of a room, it is greatest during the day. The difference in temperature is due to the thermal expansion and contraction of solids.
