FD mine local fan rotating axial flow fan

FD-improving optimization of mine local fan rotating axial fan apparatus Mine Main method now in the process of coal mine main ventilator applications mainly centrifugal, axial flow types. Mine Main device performance directly affects the size of the wind mine tunnel. If FD mine local fan rotating axial flow fan excessive wind, make personnel difficulty walking, affect hearing, underground humidity, FD mine local fan rotating axial flow fan speed too easily lead to workers suffering from rheumatic disease, the economy of the ventilation system is reduced; if the wind is too small, can not effectively diluted exhaust gas and other harmful gases emission in the production process, threaten the security of production and affect workers' health, overhead line electric locomotive prone layered on top of the roadway gas accumulation, can easily lead to gas blasting accident stringing locomotive through to coal mine production safety and security. Therefore, the performance and the actual situation of the mine main mine fan means match is very important. 1 FD mine local fan axial fans rotating economy optimization 1.1 FD FD mine ore spin on the economic operation bureau fan axial fan unit with rotating local fan axial fan unit consists of motor, motor and fan drive and Fan components. It runs the overall efficiency of the economy of this Part shall be measured. Improve the overall efficiency of the fan, can, transmission efficiency and motor efficiency measures taken to improve the efficiency of the fan from the three aspects, the most important is to improve fan efficiency.
