变频轴流式风机风量-效率关系研究

Study on the Relationship Between Air Volume and Efficiency of Variable Frequency Axial Flow Fan

针对矿井主要通风机运行时可能存在功率较大、耗电量居高不下的问题,从理论方面对风机特性曲线规律展开研究,搭建了矿井主要通风机比例模型并进行了风机特性研究实验。通过该实验可为轴流式风机选出最优效率,为现场通风管理提供科学依据。

In view of the problems that the high power and high power consumption in the operation of the main fan in the mine.The characteristic curve law of the fan is studied theoretically,the proportional model of the main fan in the mine is built,and the fan characteristic research experiment is carried out,through this experiment,the peak efficiency of axial flow fan can be selected and the scientific basis for on-site ventilation management can be provided.
