Air compressors are widely used in rail transit, mainly in the following aspects:

1.Braking system: The air compressor is the power source of the train braking system, and the braking operation is realized by compressed air. Air is compressed and stored during braking and released when needed, ensuring rapid response and effectiveness of braking.

2.Suspension system: The air compressor is used in the suspension system of rail transit vehicles to control the compression and release of air to adjust the suspension height. This is essential for the vehicle's driving stability and ride comfort.

3.Air conditioning system: The air conditioning system of rail transit vehicles also relies on air compressors, which use compressed air to promote air circulation and fan operation to maintain the appropriate temperature and humidity in the cabin.

4.Door control system: The air compressor plays an important role in the opening and closing operation of the door, controlling the compression and release of air, and improving the speed and accuracy of opening and closing.

5.Pneumatic tools: In rail transit construction, a large number of pneumatic tools need a stable air source, and the air compressor provides an air source to ensure the efficient use of tools.

6.Drainage system: During construction, air compressors are also used in drainage systems to help treat wastewater and sewage through compressed air.

7.Application of oil-free air compressor: Some rail transit vehicles use oil-free air compressor to provide more efficient and clean power and reduce maintenance costs.

These applications show that air compressors play a vital role in the field of rail transit, which not only improves the operation efficiency and safety of trains, but also contributes to the intelligence, energy saving and emission reduction of rail transit.
