一般情况下,引起风机振动的原因主要有以下几点:

(1)转子动、静不平衡引起的振动。这除了与制造、安装、检修的质量有关外,运行中发生的不对称的腐蚀、磨损和叶片不均匀的积灰;转轴弯曲,转子原平衡块位移或脱落,以及双侧进风风机两侧风量不均衡,都有可能引起振动;

(2)安装问题。风机、电动机对轮对中不准,没能使两轴线互为平滑的延续线而产生振动;

(3)由风管引起的振动波及到风机,也能使之产生振动;

(4)基础问题。基础不牢固或机座刚度不够,如基础浇注质量不良或二次灌浆不实,地脚螺栓或垫铁松动;机座连接不牢或连接螺母松动;机座结构刚度太差等也能产生振动;

(5)风机转子结构问题。转子的紧固件松动或活动部分间隙过大,如轮或联轴器与轴松动,轴承间隙过大,滚动轴承固定螺母松动等,都会使振动加剧。

以上答案仅供参考。
