摘 要:简要介绍了该风机的技术原理、设计制作、性能检验和工业性试验状况。该机具有电动气动抽出压入等功能 ,当工作面突然停电时风机会自动改由压气驱动 ,保持其正常运转 ,避免因局部风机停运而出现的瓦斯事故。The mine multifunctional auxiliary fan can be operated electrically or pneumatically and be used for exhaust or forced ventilation, when the power supply at a face suddenly cut off, it can automatically change from electrical driving to pneumatic driving and keep normal operation, thus averting gas accident due to shutdown of the auxiliary fan. This fan fills the gap in our country. This paper gives a brief description of the technical principle, design, manufacturing, performance test and commercial test of this fan.
