摘要
煤矿主扇风机在设计时预留的余量较大,因而在前期运行时能量演费严重。通过变频改造,可根据所需风量的大小,来调节风机的转速,从而改变风机的输出功率,达到节能的目的。
It is reserve a large margin of Mine main fan in the design,which results serious waste of energy in the early run-time.Through the frequency transformation,it can adjust the fan speed according to the required size of the wind,thus changing the output power of the fan to save energy.
