       工厂用锅炉离心通风机长时间运转会加剧叶轮的磨损,为了降低置换成本,对叶轮进行修理是需要的,如何进行现场修理呢?

锅炉离心通风机

       首先切除离心通风机叶片磨损部分后,用砂轮将叶片切平,去除毛刺,打磨30度的倒角。

       通过测量,每片叶片焊接5根4根。要求双面焊接。焊接前,需要准备材料和叶片。焊接时,每片叶片先焊接一根焊条,再焊接另一片对称叶片。其目的是避免锅炉离心通风机局部焊接过热,造成叶片变形。

       焊接的焊缝不得有气孔和砂眼。焊接叶片后,对焊缝进行渗透和检测。检查离心通风机前喷洒清洁剂,然后涂抹渗透剂,喷洒显示剂。如果发现裂缝,用砂轮打磨焊缝,然后重新焊接。

       焊接叶片后,焊口应退火。采取以下措施:用气枪加热焊口200~300°℃,均匀烘烤2~3min。

       修好叶片后,在备料工作面上堆焊抗磨层。需要就绪后,可以启动锅炉离心通风机试运行,看是否有异常
