GB/T 21151-2007 Technical specification of main axial fan-mine
Abstract
This standard specifies the technical requirements, inspection methods, inspection rules, marking, packaging, transportation, and storage of axial flow main ventilators used in coal mines. This standard applies to main ventilators used on the surface of coal mines, which are driven by three-phase electric motors and operate at an altitude of no more than 1000m, with a gas medium temperature of -20°C to 40°C and a relative humidity of no more than 95% (at 25°C). Other surface-mounted main ventilators used in other mines can also be used as reference.
