摘要
利用增阻调节的方法,改变回风巷道中的风量,并利用DF-3C多路风速仪测试巷道风速,得到不同工况下风机的风量以及静压,根据风量和静压的关系,采用多项式拟合的方法绘制出风机的特性曲线,为风机参数的改变提供技术指导。
By increasing resistance regulation to change the air quantity in returned wind channel, and using DF-3C multi-channel anemoscope to test wind speed, the air quantity and static pressure under different working conditions were measured. According to the relationship of air quantity and static pressure, performance curve of ventilating fan was drawn by using polynomial fitting method, which provides technical guidance while changing the parameters of ventilating fan.
