我国金属矿山通风机耗电量占整个井下设备耗电量1/3。降低通风机的能耗,避免能源的浪费,对我国金属矿山节能具有重要意义。我国金属矿山大量采用70B_2系列风机和2BY系列风机作主扇,JF或JBT系列风机作局扇。这些风机都是国外四十年代设计、我国在五十和六十年代的产品,内效率最高为70％,较目前国内外生产的新型高效风机低15％。因此,需要选用合适的新型高效节能
China’s metal mine fan power consumption accounts for the power consumption of the entire underground equipment 1/3. Reducing the energy consumption of the ventilator to avoid the waste of energy is of great significance to the energy conservation of metal mines in our country. China’s metal mines use a large number of 70B_2 series fans and 2BY series fans as the main fan, JF or JBT series fan for fan. These fans are designed in the forties of the world. In the 1950s and 1960s, our products had a maximum internal efficiency of 70%, which was 15% lower than that of the new high-efficiency fans produced at home and abroad. Therefore, the need to choose the right new energy efficient
