摘要
对270km/h高速列车牵引电机冷却风机皮托管流量测量方法进行了研究,通过地面标定实验得到了皮托管动压与风机流量的关系。研究结果表明,皮托管流量测量法可用于实时检测列车运行过程中风机冷却风量。
The investigation on measuring the cooling fan flow of270km/h high speed train with pitot-tub is per-formed in this article.The relation between pitot-tub dynamic pressure and fan flow is obtained by ground stan dard iz-ing test.The investigation results show that the measuring flow method with pitot-tub is adap ted to measure the real air volume of fan during the train running process.
