       环氧玻璃钢风机进出口管段风速很高,高速通风会扰动管路,使管路产生共振。一般来说,风机的进出口管由法兰和叶轮外壳刚性连接,管道的振动需要传递到外壳上。外壳通常与轴承座相连,导致轴承座振动,导致整个玻璃钢风机振动。

       此类振动的避免措施有:

       1、检查环氧玻璃钢风机壳体,如壳体存在裂纹的或磨损及其腐蚀严重的,应固定或整体更换;

       2、在振动明显的管段安装管路减振器,使管路与风机外壳灵活连接,减少或缓冲振动。常见的管路减振器,如KTX可绕橡胶软接头,即管路减振器,一般安装在环氧玻璃钢风机出口附近,减震效果明显。此外,一些管道补偿器波形补偿器等一些管道补偿器也能起到减震作用;

       3、出口管路可以在条件允许的情况下进行优化。一般来说,弯头更容易干扰管路,引起振动。因此,环氧玻璃钢风机出口段应有不小于5m的直段,以减少出口阻力损失,达到平稳输送介质的目的;

       4、叶片阀应优先考虑玻璃钢风机进风口调节阀。工作时可实现管路内输送介质的均匀分布,避免剧烈涡流振动。
