摘要
通过理论模型分析了对旋式风机的风压特性和功率特性 ,结果表明 ,两级动叶风压特性的差异是导致Ⅱ级电机易过载的根本原因 ,提出了防止电机过载的方法。
With the theoretical model, the paper analyzed the air pressure characteristics and power characteristics of the counter rotary fan. The results showed that the differential of the two stage rotary van characteristics was the fundamental cause of the second motor to be failed. The paper provided the method to prevent the overload of the motor.
