Railway track circuits are prone to rust (or scale accumulation) on their surfaces in the open air due to rain, sun and other factors. When the surface and internal rust 

of the rails are severe, it is easy to cause poor rail circuit shunting, which affects the transmission of railway signals. Currently, two methods are mainly used to remove

 the rust layer of operating rails: manual modification and rust removal, and large-scale rail rust removal and transformation machines.

Laser cleaning equipment is suitable for operators to work alone, has low cleaning costs, is environmentally friendly and efficient, has good cleaning quality, does not 

damage the rail base material, does not need to apply for a railway transportation plan, can work easily or can complete the work automatically through remote control.

 These advantages are the existing cleaning methods. Irreplaceable  

Features of laser cleaning

Non-contact: convenient for cleaning special-shaped parts, holes, grooves and other corners that are difficult to reach with traditional cleaning methods.

Fine processing: The paint on a certain part of the substrate can be selectively cleaned.

Environmentally friendly and pollution-free: no chemical reagents are required; the solid powder layer produced by paint removal can be recycled and processethrough the dust collection system.

Clean and non-destructive: It can remove the surface coating of various substrates and achieve a high degree of cleanliness. A short-term impact will not damage the 

substrate.The surface is heated without damaging the substrate.

Low cost: laser paint removal compared to traditional paint removal methods

During the inspection and maintenance of rail transit equipment, there are a large number of parts that need to be cleaned. Key components installed or suspended outside the car body, such as axles, gearboxes, brake discs, etc., need to be removed from oil, rust, paint and other contaminants. Because there are many types of dirt, different cleaning methods need to be used, and even parts must be disassembled, resulting in a long cleaning process. There is also an urgent need for an environmentally friendly and efficient cleaning method. Laser cleaning can not only effectively remove rust, oil stains, paint, oxide layers, etc. on the surface of materials, but it can be used for multiple purposes. Backpack-type, movable and fixed equipment can also be customized as needed to meet the cleaning needs of rail transit in different situations.
