摘要
通过对矿用对旋通风机的分析及试验研究,阐明了带扩散筒—塔和带消声器扩散筒的对旋风机效率比JBT系列低。指出了我国对旋热所带来的损失,同时阐述了"双85"和局部通风如何避免采用大功率局扇的方法。
This paper specifies the efficiency of counter-rotating fan with diffuser-tower and silencer diffuser is lower than JBT series based on the analysis and testing research on counter-rotating fan for mine. The losses due to counter-rotating heat is pointed out and the method for'double 85'and local ventilation to avoid adopting local fan with large power is also specified.
