摘要
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 actual operation efficiency of ventilator in coal mine, and it is hard to execute torque method and electric measurement on production spot, the paper offers basic principle of thermodynamic measuring method, and deduces efficiency measurement expression. Actual measuring result shows that the method is simple and easy to work.
