-各位大佬: 저희 회사에서 신규 프로를 설계하면서 변압식 인후기기一台变频引风机选了一台变频引风机一个月前提交的设计参数为引风机前烟气温度烟气温度182℃引风机前静压-5500Pa引风机前静压-55005Pa引风机后静压2222Pa引风机后静压2222Pa一个月后到货的铭牌参数为工况流量35万/立方米工况流量35万/立方米风机全压755Pa风机全压755Pa调试过程中发现引风机前静压只有-1650Pa引风机前静压只有-165Pa风机后静压245Pa风机后静压242Pa业主来的烟气流量也并没有原设计那么大但是引风机频率已经拉到了48Hz电流77A请问论坛各位大佬专家在这种条件下引风机频率这么高的现象正常吗这是设计条件变更的原因还是设备本身的原因谢谢各位！

额定频率是多少如果实际频率低于额定值就没问题一般至少是工频55Hz48Hz正常问题是入口静压参数低于设计值很可能风机本身就不具备这个能力目前状态确认下风机实际能力是否满足操作需求吧。

不正常按你现在的压力大概只有设计压力的66%不到频率又这么高流量一定会比设计流量还大这个可以按照风机曲线去比较而且你实际工况点的效率会很低
