长期以来,有关的规程以及矿井主要通风机的生产和使用单位都将通风机效率作为衡量其性能的一个重要指标,通过多年现场实测认为,影响风机效率的因素太多,是一个很难测准的指标量,过分强调有失偏颇,而且也不完全符合经济原则,从而提出采用综合效率来评价矿井主要通风机装置性能的观点,并对2种评价方法进行了阐述比较。
For a long time, relevant regulations and units of production and use of mine’s main ventilators regard the efficiency of ventilators as an important index to measure their performance. Through many years of field measurements, there are too many factors that affect the efficiency of turbines, which is a difficult measure Of the amount of indicators, excessive emphasis is biased, but also not fully in line with economic principles, and thus put forward the use of synthetic efficiency to evaluate the performance of the main mine ventilator device point of view, and two kinds of evaluation methods are described and compared.
