西石门铁矿已有20多年的开采历史,考虑到复杂的生产条件和工作环境,其井下主通风系统均选用功率较大的设备,电动机采用星角启动、全速运行方式,存在大马拉小车现象,耗能十分严重。1主通风机技术状况中一采区91水平主通风机采用高效、低噪声、无驼峰DK45-8-No.22型对旋轴流式通风机,与之配套的电动机功率为2×200kW;南二采区40水平主通风机采用高效、低噪声、无驼峰K40-6-No.20型
West Shek Mun iron ore has more than 20 years of mining history, taking into account the complex conditions of production and work environment, the underground ventilation systems are selected for their larger power equipment, motor star angle start, full speed mode of operation, the existence of the big car Phenomenon, energy consumption is very serious. 1 main fan technical conditions in a mining area 91 horizontal main fan with high efficiency, low noise, no hump DK45-8-No.22-type axial-flow fan, with the accompanying motor power of 2 × 200kW; South Second mining area 40 level main fan using high efficiency, low noise, no hump K40-6-No.20
