Mine intelligent local ventilation system

Mine intelligent local ventilation system is composed of FBD series mine flameproof type compressed-in anti-rotating axial flow local fan Y type air flow changer fixed frame BPJ series mine fan flameproof and intrinsically safe type frequency conversion governor and other units. Mine intelligent local ventilator is a closed-loop control system, its main function is to determine the amount of air supply through the parameters collected by the underground sensor underground sub-station, to avoid the existing local ventilator wind blowing phenomenon, so as to solve the problem of local ventilation demand for wind supply Starting from the requirements of safety and energy saving, the system adopts the control system composed of PLC and inverter to adjust the fan speed in real time, so as to achieve the effect of real-time warning and man-machine dual control of on-demand wind supply disaster prevention and reduction, so as to make the automatic discharge of local ventilation gas effi…
