摘要
本文介绍了矿用对旋轴流式主通风机的现场测试的特点、基于压差法的测试方法及有关的注意事项。文中介绍的测试及计算方法准备工作量小 ,对仪器仪表的要求不高 ,计算过程简单。特别适用于对旋式主通风机作抽出式通风时的一般工程需求 ,如新安装的对旋轴流式主通风机投入运行前的见证检验、运行过程中的风机调整了叶片安装角度、更换了叶片等情况需掌握通风机运行性能所需作的性能测定。
The paper introduced the characteristics, methods and some aspects that must be noticed about the performance test of the contrarotating axial fan for mine ventilation at the actual locale based on difference of static pressure.The test and its calculation in the paper needs less amount of work preparation,lower requirements about instruments and meters,besides,its calculation process is very simple.Especially it applies to the general projects in which contrarotating axial fans ventilate,such as the witness inspection before newly-installed Contrarotating Axial Fans running and the performance test when blade stagger angle is adjusted and blades are changed during running.
