用全压管和静压感压器准确测定矿井主要通风机风量

Precise Measurement of Air Quantity of Main Mine Fan by Total Pressure Tube and Static Pressure Sensor

通过对矿井主要通风机的内部流场分析，指出了矿井主要通风机传统测试方法存在的问题，提出了用全压管、静压感压器现场测定矿井主要通风机风量的方法。

Through analysis of flow field within the main fan,the author indicated the problems existing in conventional measuring methods for main fan,then proposed the method to measure air quantity by total pressure tube and static pressure seneor and demonstrated the correctness of the method on theory and practice.
