1C31203G01产品特点
能耗分析
主通风机为轴流式排风机，风机两台，一用一备，每台功率800kW，下图4为AGF606-2.44-1.3-2特性曲线图，R1为矿井的通风阻力曲线，R2为调整风门后的阻力曲线，由图4可知，当需风量为QA时，动叶角度为-50时、风机效率小于72%，这时需将动叶角度调至-100（图中的B点），以提高风机的运行效率，这时风机的运行效率约为74%，由矿井的通风阻力曲线R1和风机的性能曲线图，可知风机在动叶角度为-50时，效率较高，这时可通过变频器调节风机转速调至A点，以满足风量要求，这时风机运行在佳状态，此时变频器的运行平均功率为：P变=276.3kW，变频运行与风机工频运行相比风压损失功率为：1C31203G01
