Laser Cleaning Solutions for Efficient and Green Rail Transit Maintenance

In the rail transit industry, maintaining critical components such as wheelsets, traction rods, and gearboxes has long been challenged by the low efficiency, high pollution, and high cost of traditional paint removal and rust removal methods. Laser cleaning technology, with its high efficiency, zero emissions, and intelligent operation, is now emerging as a core driver for industrial upgrading.

Limitations of Traditional Cleaning Methods
1. Low Efficiency: Removing paint from a single wheelset axle can take 30–60 minutes and often requires secondary manual treatment.
2. High Pollution: Chemical solvents cause floor corrosion and wastewater discharge issues, while sandblasting generates harmful silica dust.
3. Rising Costs: Fast wear of consumables (steel wire wheels, abrasives), expensive protective gear, and hazardous waste disposal drive up expenses.

Advantages of Laser Cleaning
1. Faster Processing: A combined light source (2000W continuous + 300W pulsed) enables quick removal of thick coatings and precise cleaning of oxide layers, greatly reducing axle cleaning time.
2. Zero-Emission & Eco-Friendly: No chemicals required, eliminating wastewater and dust emissions in line with carbon reduction goals.
3. Intelligent Cost Reduction: Integrated AI visual inspection and automated path planning reduce manual intervention, lower consumable use, and cut annual maintenance costs.

Handheld Laser Cleaning & Precision Cooling Solutions
In laser cleaning systems, the industrial water chiller is a critical component to ensure stable laser performance. The handheld laser cleaning all-in-one machine is increasingly favored in rail transit maintenance for its ease of operation and flexibility.

The TEYU CWFL-6000ENW12 industrial chiller delivers efficient cooling performance, ±1°C temperature control accuracy, Modbus-485 intelligent communication, and multiple safety protections including compressor delay start, overcurrent protection, and water flow/temperature alarms. Its design ensures high-power laser cleaning systems operate without overheating, preventing power loss or downtime. Real-time monitoring and fault alerts further reduce maintenance costs, extend equipment lifespan, and ensure continuous industrial productivity.

Driving the Green, Intelligent Future of Rail Transit Maintenance
Laser cleaning technology is paving the way for a greener and smarter approach to rail transit equipment maintenance. With continuous technological advancements and industry collaboration, it is set to become an integral part of the entire lifecycle management of rail transit assets, injecting sustainable power into the development of China's intelligent manufacturing.
