降低异步电动机通风噪声的方法研究
|
摘要
分别从声源和传播方向两方面控制通风噪声,研究降低高压方箱异步电动机通风噪声的方法。通过大量实验数据表明,在温升允许的情况下,采用优化风扇直径及风扇叶结构的方法,降低通风噪声的效果显著。经过多次优化高压方箱异步电动机的消音罩结构,分别采用在进风口及在出风口设置消音罩,两种结构均可有效降低通风噪声。
The method of reducing ventilation noise of high-voltage square box induction motor is researched to control it from aspects of sound source and propagation direction,respectively. A large number of experiment data show that the method of optimizing fan diameter and fan blade structure can reduce ventilation noise remarkably in the permitted case of temperature rise. Through repeatedly optimizing the muffler structure of high-voltage square box induction motor,it is verified that the two methods of respectively setting the muffler at air outlet and inlet can effectively reduce ventilation noise of the motor.
