高原严寒地区海拔高,大气压力低,空气干燥,尘土多,温差大,制氧中应掌握以下几点:(1)根据空气稀薄的特点,改善压缩机性能,增大加工空气量,必要时要更换压缩机的皮带轮,提高压缩机的转速。(2)加工空气量不足的情况下,适当减少氧的产量。(3)根据气候干燥的特点,增大散热器的冷却水 High altitude severe cold areas, low atmospheric pressure, dry air, dust, temperature, oxygen should master the following: (1) According to the characteristics of thin air to improve compressor performance, increase the amount of processing air, if necessary To replace the compressor pulley, increase compressor speed. (2) When the amount of processing air is insufficient, reduce the oxygen production appropriately. (3) According to the characteristics of dry climate, increasing the radiator cooling water
