摘要
介绍了沙坪煤矿通过计算矿井通风阻力,确定了通风容易和通风困难两个时期主扇运转时的工况点,计算出主扇的实际通过风量,确定了主扇工况点,选定了该矿井前后期风机型号均为2K60-No28,n=600r/min的对旋式轴流风机,通风容易与困难时期均选用同一型号为T118/44-8的同步电动机。
In Shaping mine, the ventilation resistance was calculated and then the operation point of main fan was determined during easy-ventilation and difficult-ventilation periods. The real ventilation volume of the main fan was calculated. According to the operation point, the same contra rotating axial fans （2K60-No28, n=600r/min） were selected for the previous and subsequent periods and the same synchronous motors （T118/44-8） were also selected for the easy/difficult-ventilation periods.
