采用多台扇风机并联工作的矿井,各扇风机工作风路的排风量应与该风路的风阻状况相适应。风阻小,通过能力大的风路,应尽量利用它多排风;风阻大,通过能力小的风路,则应少排风。这样,可减少由于分风量与各风路风阻状况不相适应而产生的附加能量损失。在各条风路风阻状况保持不变的情况下,各并联扇风机工作风路之间,存在一个最佳的分风方案,即在此分风状况下,全矿通风的总能量损失最小。下图表示两扇风机并联工作的通风系
The use of multi-fan parallel work mine, fan fan working air exhaust volume should be consistent with the air resistance of the wind conditions. Wind resistance is small, through the capacity of the wind, should make full use of it more exhaust; wind resistance, through the ability of small wind, should be less exhaust. In this way, it is possible to reduce the additional energy loss caused by the incompatible air volume with the air resistance of the air ducts. Under the condition that the wind resistance condition of each air duct remains the same, there exists an optimum air distribution scheme among the working air channels of the parallel fan fans, that is, the total energy loss of the whole mine ventilation is the minimum under this air distribution condition. The figure below shows the ventilation of two fans in parallel
