Disadvantages of common cleaning methods in the rail transit industry
Laser cleaning has the incomparable cleaning effect and advantages of traditional cleaning methods. This article will first list traditional traditional cleaning, including sandblasting, mechanical polishing, high-pressure water jet, chemical cleaning, ultrasonic cleaning, etc. The effects and problems of various methods .
1. Equipment grinding and cleaning
There are problems such as dust scattering, noise pollution, uneven cleaning effect, and potential safety hazards;
2. Ultrasonic cleaning
The size is limited, the offline cleaning takes a long time, the drying procedure is increased, and the equipment occupies a large area;
3. Chemical cleaning
Serious environmental pollution, serious occupational health hazards, high cost of consumables, and complicated procedures;
4. Traditional manual cleaning
It has low cleaning efficiency, high labor intensity and uneven cleaning effect.
Advantages of laser cleaning in rail transit manufacturing and maintenance
The principle of laser cleaning
Laser cleaning refers to the process of using a high-energy laser beam to irradiate the surface of the workpiece, so that the surface dirt, particles, rust spots and other attachments are instantly evaporated or peeled off, so as to achieve cleaning and purification. The cleaning effect needs to be achieved by laser cleaning equipment. The main components of laser cleaning equipment include computer control system, laser system, beam adjustment system, etc., in addition to some supporting equipment: such as dust removal purification system, manipulator, laser induced breakdown spectrometer (LIBS), visual positioning system and thermal imaging system.
Features of Laser Cleaning
Laser cleaning has the characteristics of no grinding, non-contact, no thermal effect, and is suitable for objects of various materials. It can achieve precise and controllable thickness of the cleaning area, uniform cleaning quality, intelligent detection and control, no damage to cleaning, and reduced cleaning operation difficulty. , and has the advantages of green environmental protection, maintenance-free, low operating costs, and improved operating environment, and is considered to be the most reliable and effective solution for precision equipment cleaning.
Application case of laser cleaning in rail transit manufacturing and maintenance
Laser cleaning has many application scenarios in the manufacture, maintenance and repair of rail transit (subway, urban railway, high-speed rail and EMU, ordinary train, etc.). Such as bogie weld cleaning before flaw detection, wheelset rust removal & wheelset removal, container weathering steel weld bead cleaning, ferritic stainless steel weld spot cleaning, wheel/bearing rust removal, paint stripping, rail cleaning, cleaning before flaw detection ( Signal continuity, flaw detection, paint stripping, rust removal), cleaning of workpieces before and after welding.
Laser cleaning has huge application scope and industry advantages in rail transit manufacturing and maintenance. In the future, Legent Laser will provide customers with safer, more efficient and more environmentally friendly products and solutions based on the application needs of specific scenarios, with advanced technology advantages and rich product experience, and strive to promote laser cleaning equipment to become the industry standard.
