The wheelset(also named as train axles) shot blasting cleaning machine is designed and manufactured according to user requirements, mainly used as a specialized equipment for shot blasting and rust removal of railway vehicle wheelsets.
Wheelset shot blasting machine consists of blasting wheel assembly, shot blasting chamber, abrasive circulation system (separator, bucket elevator, screw conveyor), wheel rotating device, axle box rotating device, dust collecting system, electrical control system and pneumatic control system and other components. The whole machine adopts two forms of automatic and manual control, and can realize the linkage of the whole machine, which has the advantages of high productivity, high degree of automation, simple structure, convenient maintenance and reliable operation.
Through shot blasting cleaning, dirt, rust, oxide scale, sand and slag on the surface of the wheel can be removed, making the surface of the workpiece appear metallic in its original color. At the same time, it can reduce the internal stress of the workpiece, improve the corrosion resistance and fatigue resistance of the product, and extend its service life; Optimize the surface process state of metal materials.
The application of shot blasting technology to achieve rust removal and strengthening is still the most economical and reliable method in the world.
maintenance of wheel sets for train cars, wagons and locomotives
1. The arrangement of the shot blasting chamber and the blasting wheel are determined after computerized three-dimensional dynamic blasting simulation.
2. There is a workpiece detection device to meet the requirements of automatic operation.
3. 8 sets of centrifugal blasting wheels with large shot blasting capacity and high blasting speed are adopted to fully meet the requirements of production program.
4. Adopting pneumatic labyrinth lift gate to ensure no steel shot splash.
5. With the function of rotating wheel pairs and pneumatic pusher wheel pairs down the line.
6. Adopting the most advanced real full curtain multi-stage wind separator, adopting special polyester wire core elevator drive belt, elevator reel adopts chamfered squirrel cage structure, which not only increases the friction to avoid slipping, but also prevents scratching the belt, adopting remote control projectile controller, and equipped with a projectile refillers to facilitate the addition of projectiles.
7. Adopting cyclone settling room + high-efficiency pulse bag dust collector dust collecting method, the dust collecting system to ensure that the environmental dust concentration at the work site ≤ 5mg/m3, dust removal system exhaust concentration<50mg/m3.
8. The whole system adopts PLC control, which can be controlled automatically, and the parts of the equipment run in sequence according to the pre-programmed program; it can also be controlled manually, which is convenient for the debugging and overhauling personnel to make adjustments to the equipment, and the electric control system is equipped with a fault detection device.
