直接反转反风轴流风机在我国煤矿的使用前景

PRESPECT OF INVE RSE VENTILATION IN CHINA'S COAL—MINES BY SIMPLY REVERSING THE AXIAL FAN

不调整任何叶片实现矿井轴流通风机直接反转反风是煤矿进风井口附近,进风井筒及其井底车场等处火灾事故反风的理想途径,本文对全国煤矿主通风机的实际运行工况范围和发展趋势进行了统计分析,确定了这种风机在我国煤矿中最大可能的应用范围。

It is preferred to use the axial Fans which can reverse air flow during the inverse ventilation by its simple reversion. The real operation scope and tendency of major Fans in China's coal-mines are discussed in the present paper. As a result,the using, range of this kind of fan in China's coal-minesis already defined.
