电针对煤矿通风机实际运行效率,在现场难以实施扭矩法和电测法实测的现实,研究得出采用热工测量法的基本原理,并推导出效率实测表达式。实测结果表明,此方法简便易行。
According to the actual operation efficiency of coal mine ventilator, it is difficult to carry out the actual measurement of torque method and electric measuring method in the field. The basic principle of thermal measurement method is deduced and the actual measured expression is deduced. The measured results show that this method is simple and easy.
