102. Why is cooling water needed for the chimney frame?
During operation, the ambient temperature around the smoke exhaust fan is quite high; consequently, the temperature of the supports on both sides also rises. This causes thermal expansion of the steel supports, resulting in an elevation of the centerline of the fan shaft. As a result, the unit cannot operate normally. After activating the cooling water system for the supports, their temperature remains relatively stable, thereby maintaining the elevation of all shaft centerlines of the unit.
During operation, the temperature of the environment surrounding the smoke extractor is high, which causes the temperatures of the two machine bases to rise as well. This leads to thermal expansion of the steel bases, resulting in the upward movement of the axis of the smoke extractor; as a result, the unit cannot function properly. By supplying cooling water to the bases, their temperatures can be kept relatively stable, thereby maintaining the constant elevation of the axis center.
Prevent shaft deformation and maintain the elevation of the unit’s shaft center at the same level.
