信息摘要:
噪音的大小与叶速的6次方相比。玻璃钢离心风机组装精密不产生大振动时,风机噪声主要来自风机叶片使空气流动引起两面压力差,使叶片本身产生振动,气体干扰引起的振动波对玻璃钢风机叶片产生程度的冲击,产生大噪声…

噪音的大小与叶速的6次方相比。玻璃钢离心风机组装精密不产生大振动时,风机噪声主要来自风机叶片使空气流动引起两面压力差,使叶片本身产生振动,气体干扰引起的振动波对玻璃钢风机叶片产生程度的冲击,产生大噪声。

玻璃钢离心风机

加压后的风从玻璃钢风机中排出时,随着叶片前后的风流量的释放,叶片前后的压力大小不同,风流方向不稳定,分散的风对叶片和壳体产生冲击,冲击过大或到达值容易损坏机械部件。玻璃钢离心风机主轴和马达轴偏心时,风机在工作中产生剧烈振动,旋转的风机产生较大的离心力,给主轴带来冲击,产生剧烈振动,玻璃钢风机寿命也缩短。组装时,应注意调整轴,使工作轴的连接轴位于同一位置。

此外,在整体组装时,底座的安装不稳定,玻璃钢离心风机的旋转产生很大的圆周力,风机的固定强度和紧固度也应该考虑的问题也很严重。风机工作时产生噪音时,应重视玻璃钢风机本身或组装过程中发生问题及解决,可以避免事故的突然发生,还可以延长风机的寿命。
