Mine Main mine ventilation system is the most important equipment. Because of mine axial ventilator power, high power consumption, but in the actual production efficiency and low operating but there is a greater waste of energy and, therefore, improve the operating conditions the fan unit that is efficient, energy-saving reduction Consumption of great significance. GB / T13470-2008 standard ventilator economic operation: the actual operating efficiency of the unit compared with the rated efficiency, the ratio is greater than 0.85, the unit finds economic operation; the ratio between 0.70 to 0.85, then finds reasonable unit running; it ratio is less than 0.70, the identified unit operation uneconomical. At present, China's production of mine maximum static efficiency axial fan is about 85 percent, according to the economic operating conditions (in this case only consider the efficiency of the fan itself, without regard to motors and other electrical equipment), operating efficiency fan That condition should not be less than 72.25% efficiency. According to statistics, China's coal mine axial main ventilator over the entire service life, operational efficiency is less economical operating conditions, most of the major mines operating efficiency axial flow fan is far less than the national economic performance criteria. The results in 2011, from the province coal mine safety technology center for testing of the provincial coal mine axial main ventilator, the majority of the mine reach the national standard economic operating conditions, including the two state-owned coal mines FBCDZ type used the efficiency of the mine main fan was 32.5% and 60%, respectively, well below the national regulations of not less than 85% of the maximum efficiency, ie the efficiency of not less than 72.25% of the economic performance criteria.
