矿用对旋式主通风机最佳工作特性的匹配性研究

Study on Matching of Optimum Working Characteristics of Mine Counter-rotating Main Fan

针对矿用对旋式通风机在不同巷道长度情况下的转速匹配性情况进行试验验证。首先介绍对旋式风机气动性能试验台的设置,对风机气动性能试验数据进行分析,探究风机特性与管网特性的匹配性,结果表明,通过调整对旋式风机的工作状态能满足不同长度巷道的通风要求,极大地降低了通风机工作时对电能的消耗,对煤矿井下通风机系统的调节具有指导意义。

In view of the matching of rotating speed of counter-rotating fan under different roadway lengths,this paper first introduces the setting of pneumatic performance test bench of counter-rotating fan,analyzes the experimental data of fan’s pneumatic performance,and probes into the matching between fan characteristics and pipe network characteristics.The results show that the working state of counter-rotating fan can meet the ventilation requirements of different lengths of roadway.It greatly reduces the consumption of electric energy when the ventilator works,and has great guiding significance for the adjustment of underground ventilator system in coal mine.
