Description

Technical Field

[0001] The utility model relates to the technical field of locomotive ventilation, in particular to a traction ventilation device for a locomotive. Background Art

[0002] The ventilation device is an important component of the locomotive traction motor cooling system. When the locomotive is running, the traction motor generates a large amount of heat. If the heat cannot be dissipated in time, the temperature rise of the traction motor will increase sharply, which will cause great damage to the locomotive traction system and cause the train to fail to operate normally. This requires a traction ventilation device to cool the traction motor so that its temperature rise is within the allowable range.

[0003] However, the ventilation volume of existing traction ventilation devices is mostly difficult to adjust when working. Too little air volume may lead to poor ventilation effect, while too much air volume may increase energy consumption and noise, resulting in low efficiency and increased energy consumption in different working environments. In addition, the ventilation device may generate loud noise and vibration when running, and long-term vibration and noise will have adverse effects on the surrounding environment. Therefore, the market needs a traction ventilation device for locomotives. Utility Model Content
