Axial flow fan is a fan of mine, because of its use of the special nature of the industry and the applicable sites, and large differences in performance parameters and dimensions with the general axial-flow ventilation, so go do separate out a class. Classification and main mine fan model divided according to whether the explosion-proof type and general type Y6-41 boiler fans, explosion-proof models generally BK, BDK, FBCZ, FBCD, FBD, FBCDZ etc. Y9-26 boiler fans, common general model There are K, JK, DJK and so on. By product structure is generally divided into ordinary type and rotary type, ordinary type of single leaf, common models k40, k45, jk40, jk58-1, jk56-1 etc., rotating type is divided into two, one is Double impeller double boiler fan motors, such as djk50, FBD type, the other is a double-impeller single motor, such as jk58-2, jk56-2 so on. Intelligent mine local ventilation system is a closed loop control system, its main function is to determine how much for the amount of wind through the downhole sensors, underground sub-station acquisition parameters, avoiding the existing local fan for wind, "Yifeng Chui" phenomenon, thus solving the problem of mine local ventilation demand for wind. Systems from security and energy requirements, the use of PLC and inverter control system consisting of fan speed real-time control, achieve the effect of "real-time early warning, human dual control, demand for wind, disaster prevention and mitigation", so that the mine local exhaust ventilation, gas emissions and efficient automatic safety, reduce gas accidents, energy saving.
