摘要
介绍了城郊煤矿对旋式主要通风机变频改造的原因和方案,比较了国内外变频器在主要通风机应用的现状和技术特点,通过变频改造解决了城郊煤矿通风机效率偏低的问题,分析了主通风机改造后应用的效果。
The reason and way of the frequency conversion transformation of contrarotating main fan in Chengjiao Coal Mine were introduced. The current situation and technology characteristic of frequency conversion of main fan at home and abroad were compared version have been resolved, the transformation effect of , low efficiency of main fan by frequency conmain fan was analysed.
