目前,轴流式通风机技术发展比较迅速,自70年代开始,向着高效率,大容量、自动化方向发展,特别是矿井轴流式风机的效率提高幅度较大,世界先进水平的最高静压效率为82—85％。西德蒙坦公司为开滦东欢坨矿井设计中曾介绍:西德除居住区(允许45dB)采用离心式风机外,都采用轴流式风机;鲁尔矿区现有28个矿井,除一个矿井用离心式风机外,其余全部为轴流式风机。因轴流式风机具有和离心式风机同样高的效率,并具有造
At present, the technology of axial fan has developed rapidly. Since the 1970s, it has been moving towards high efficiency, large capacity and automation. In particular, the efficiency of mine axial fans has been greatly enhanced. The highest static pressure efficiency of world advanced level 82-85%. West Germany Meng Tan Kailuan Dong Huan Tuo mine was introduced in the design: West Germany in addition to the residential area (allowing 45dB) centrifugal fan, the use of axial fans; Luer mine existing 28 mines, except one Centrifugal fan mine, the rest of all axial fans. Axial flow fans have the same high efficiency as centrifugal fans and have been made
