进行扇风机选择设计时,是以矿井通风网路特性曲线与扇风机的性能曲线交点——工况点的风量、风压、功率、效率等为指标,并以满足矿井通风的要求为依据,选用技术上合理,经济上有利的扇风机作为矿井通风的动力。高山矿井的扇风机性能曲线,由于空气密度降低,以及由于扇风机制造厂所提供的扇风机性能曲线是在标准气象条件下所作的模型试验资料绘制的。因此,扇风机安装在高山矿井通风网路上运转时,其实际性能曲线必然有所
Fan fan design selection, based on the mine ventilation network characteristic curve and fan fan performance curve intersection - point of the wind, wind pressure, power, efficiency as an indicator, and to meet the requirements of mine ventilation as the basis, Selection of technically sound, economically fan fan as a mine ventilation power. Fan performance curves for high-pit mines are plotted as a result of reduced air densities and model test data made under standard meteorological conditions due to fan fan performance curves provided by fan manufacturers. Therefore, the fans installed in the mine ventilation network running, the actual performance curve must have
