摘要
针对D3500-12煤气风机发生因疲劳破坏造成前盘撕裂飞出的事故,提出了具体的叶轮结构改造设计。改造后的叶轮提高了使用寿命2年以上,降低材料许应力35.3%,提高风机压力15%,并在多台风机成功应用。
Aiming at the front disc tearing and flying out caused by fatigue damage in D3500-12 gas fan,the concrete transformation design for impeller structure is pointed out.The impeller after transformation has improved using life more than two years,reduced material allowable stress of 35.3 % and increased fan pressure of 15 %.It has been successfully applied in many fans.
