引风机支持刚度不足引起振动的诊断与处理
摘要
经检测及分析认为某厂 1台 30 0MW机组锅炉引风机振动过大是由其基础刚度不足引起。利用小修机会
经对风机基础进行加固后
振动消失
问题得以解决。
Abstract
Through test and analysis
it was considered that the serious vibration of induced fan belonging to the boiler of a 300MW unit was caused by deficient stiffness of it’s foundation. Taking advantage of temporary repair opportunity
the said foundation is consolidated
and at last the vibration problem has been solved.
