摘要
目前部分矿山通过调整主风机的电机频率、转速与通风网络匹配,取得了一定的节能效果,但是还没有按各矿山的实际生产时段调速节能。采用LOGO分时段变频控制主风机转速及输出风量,可实现与井下作业时段同步调控主风机转速,达到更加节能的目的。
Parts of mine have achieved certain energy-saving effect at the moment by adjusting the frequency and speed of main fan to match the ventilation network.However,it does not regulate speed for energy-saving according to the actual production time of each mine.The control of underground main fan speed and air output is introduced with LOGO time-sharing and frequency conversion,so as to save energy by controlling fan speed matching the underground production time in the pit.
