煤矿主要通风机是煤矿的四大主要设备之一。老式主要通风机一般以离心式风机为主。随着安全生产技术的革新和发展,轴流式风机开始逐步取代离心式风机。轴流式风机(包括普通轴流式风机和高效率的弯掠组合正交型轴流式风机)在煤矿现场运行的最大优点是:无须设立专用反风道等繁杂
Mine main ventilator is one of the four major coal mine equipment. Old-style main fan centrifugal fan-based. With the innovation and development of safety technology, axial fans gradually replace centrifugal fans. Axial flow fans (including ordinary axial fan and high efficiency sweep combination of orthogonal axial flow fan) the biggest advantage of running in the coal mine site is: no need to set up a dedicated duct and other complicated
