鸡西矿务局为消除煤矿回采工作面上瓦斯超限而研制的通风设备JCZ—6.0型抽出式局部通风机。经1991年11月份国家能源部确定同意在东煤公司所属范围井下推广使用,目前在鸡西局累计安全回采煤量800余万吨,取得显著经济效益和社会效益。该风机将电机置于机壳外部,含有瓦斯的气体不直接和电机接触;叶轮采用A_3钢板焊接结构,二级串联,风量可达5～6m~3/s,全风压最高达到3000Pa,全压效率
Jixi Mining Bureau to eliminate coal mining face gas overhang developed ventilation equipment JCZ-6.0-type withdrawable local fan. In November 1991, the Ministry of Energy determined that it will be used in the underground area under the jurisdiction of Dongkai Coal Company. At present, over 8 million tonnes of coal have been safely recovered in Jixi Bureau, achieving significant economic and social benefits. The fan motor will be placed outside the enclosure, the gas containing gas does not directly contact with the motor; impeller using A_3 steel welding structure, two series, the air volume up to 5 ~ 6m ~ 3 / s, the maximum pressure up to 3000Pa, all Pressure efficiency
