Application

Fans are widely used in various equipment in railway accessories, such as locomotives, carriages, transformers, etc. Its main function is to ensure the normal operation of railway equipment through forced convection and heat dissipation.

(1) Locomotive fan: As the core part of the train, the performance of the locomotive directly affects the operation of the whole train. The main function of the locomotive fan is to dissipate heat and ventilate the locomotive to ensure the normal operation of the locomotive engine and electrical systems.

(2) Compartment ventilation system: The compartment is a resting place for passengers, and a good ventilation environment is essential to the comfort of passengers. The cabin ventilation system realizes air circulation by installing fans to provide passengers with a comfortable riding environment.

(3) Transformer cooling system: In the railway system, the transformer plays a vital role. In order to ensure the normal operation of the transformer, it needs to be effectively cooled. As part of the transformer cooling system, the fan helps the transformer to dissipate heat through forced convection.

Types and performance

According to application scenarios and requirements, fans are divided into many types in railway accessories, such as axial fans and centrifugal fans. These fans have different performance characteristics and adapt to different heat dissipation requirements.

(1) Axial fan: Axial fan has the characteristics of large air volume, low noise and high efficiency. It is widely used in locomotives, carriages and other occasions that require large air volume.

(2) Centrifugal fan: centrifugal fan is suitable for applications requiring higher pressure, such as transformer cooling. Its compact structure and moderate air volume can meet the heat dissipation requirements of different equipment.
