摘要
采用分布式通风机性能测定系统对东滩煤矿西翼风井2台主通风机进行了性能测定,绘制出了风量-风压曲线、风量-功率曲线和风量-效率曲线,分析了主(备)通风机在不同工况以及不同叶片角度下的通风能力。实际应用表明,该系统现场测定所需时间少,且数据处理高效准确。
A distributed measuring system of ventilator performance was used to measure performance of two main ventilators of west airshaft in Dongtan Coal Mine, and curves of blastvolume-air pressure, blastvolume-power and blastvolume-effieiency were drawn according to the measured data. Ventilation abilities of main （standby） ventilator in different condition and different blade angle were analyzed. The practical application showed that the system greatly reduces time needed for field testing and is effective and accurate in data processing.
