多年来鉴定矿井通风系统沿用的有效风量率、主扇效率、漏风率……等参数都有片面性。如,有效风量率并不表示风量分布的均匀性和合理性;漏风也并不统统有害;主扇效率实际是电能利用率的综合,涉及设备本身或选型;等等。为了寻求简便易行、能实现日常监测或定期监测、数据简单、且能反映现场状况
Over the years identification of mine ventilation system used effective air volume rate, the main fan efficiency, air leakage ...... and other parameters are one-sided. For example, the effective air flow rate does not mean that the distribution of air flow uniformity and rationality; air leakage is not all harmful; the actual main fan efficiency is the comprehensive utilization of energy, involving the equipment itself or selection; In order to seek simple and easy, can achieve daily monitoring or regular monitoring, the data is simple, and can reflect the situation on site
