风机所需电机功率是指在一定工况下，对离心风机和风机箱，进风口全开时所需功率较大。若进风口全开进行运转，则电机有损坏的可能。风机试车时最好将风机进口或出口管路上的阀门关闭，运转后将阀门渐渐开启，达到所需工况为止，并注意风机假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵的运转电流是否超过额定电流。
The motor power required for the fan refers to the larger power required for the centrifugal fan and fan case when the air inlet is fully open under certain working conditions. If the air inlet is fully open for operation, the motor may be damaged. It is better to close the valve on the inlet or outlet pipeline of the fan during the test run of the fan, gradually open the valve after the operation until the required working condition is reached, and pay attention to whether the operating current of the fan exceeds the rated current
