针对DF4B型机车在气候潮湿地区运用时压缩空气湿度过大带来的制动系统故障隐患问题,进行了风源系统空气净化技术改造,在油水分离器前加装冷凝管,在两个总风缸之间加装空气干燥器。实际使用结果表明,改造后的风源系统处理的压缩空气相对湿度可降至30%以下,解决了总风缸空气过湿问题。
In view of the hidden trouble of the brake system caused by excessive humidity of compressed air when the DF4B locomotive is operating in a humid climate zone, the air purification system of a wind source system is retrofitted. In front of the oil-water separator, Install an air dryer between the cylinders. The actual usage results show that the relative humidity of the compressed air processed by the reformed wind source system can be reduced to less than 30%, which solves the problem that the total air in the air tank is too humid.
