Pain Point Awakening: The Fatal Three Seconds of Cooling Towers<\/h3>\n

The siren of a petrochemical plant in the dead of night broke the silence - the bearing of the cooling tower fan suddenly broke, and 20 tons of blades flew out like cannonballs, smashing through adjacent equipment. A post-event investigation revealed:The vibration value exceeded the limit as early as 72 hours ago<\/strong>However, traditional manual inspections failed to detect it5<\/span>. Such accidents expose three fatal blind spots of cooling towers:<\/p>\n
