摘要
通过地面标定实验 ,对 2 70km/h高速列车牵引电机冷却风机风量实车测量方法进行了研究 ,得到了皮托管动压及风机全压与流量的关系。
The measuring method investigation on the cooling fan flowrate of the traction motor of the 270km/h high speed train through ground standardizing tests is performed. The relation between the Pitot tub dynamic pressure or total pressure of the fan and the fan flowrate is obtained by tests. The investigation results show that the measuring flowrate methods using Pitot tub and total pressure of the fan are adaptive to measure the air volume of the cooling fan air flow during the train running process.
