摘要

某钢厂除尘系统采用型号为Y4-73-11№24.5F的离心风机,运行过程出现风量风压均不能满足系统要求的情况,而且风机的振动值也超标。经分析是原风机选型不合理以及机壳刚性不足造成的,需要对风机进行改造。根据系统参数设计新的风机,采用三元流叶轮双吸型式的节能风机。风机安装时仅需对轴承座进行调整,不更换电机、联轴器等,不重新做土建,大大减少了改造成本并缩短了施工工期。改造后的风机保证了除尘系统的稳定运行,并取得了很好的节能效果。
        The centrifugal fan Y4-73-11№24.5F which air volume and pressure can not meet the requirements of the steel plant dust system during the operation, moreover, the vibration value of the fan exceeds the standard. The reason is the unreasonable selection of the fan and the lack of rigidity of the volute. The solution is to transform the fan. A new energysaving double inlet fan is designed according to system parameters with three-dimensional flow impeller. When install the new fan, only need to adjust the bearing seat, no need to replace the motor, coupling, etc.,.The modified fan ensures the stable operation in the dust removal system, and has obtained the very good energy saving effect.
