摘要
介绍了配合使用动压平均管与差压变送器在线测量风量的方法,本方法适用于不具备直管段要求且气流不稳定的实时流量检测,应用本检测方法有效解决了机车运行中牵引电机冷却通风量的动态测量。
Airflow online measurement,which used dynamic pressure mean pipe combined difference pressure transmitter,is presented. The method can realize real time measurement when there is no straight pipe section or airflow is not stable. Dynamic measuring of traction motor cooling airflow during running of locomotive can also be available using this method.
