Duomu powder feeder for PTAW & Laser Cladding
Powder feeder structure
The storage tank is used to store powder, transparent and convenient for observing the powder condition.
There is a rotating nut at the powder feeding port, which can be manually tightened to remove the nut and add powder from here.
Install a stepper motor at the powder unloading point to control the precise powder feeding during the working process. There is an on/off valve at the powder unloading port, which can be used to pour the remaining powder and reuse it.
The observation window is set to be transparent, which can observe the direction of motor rotation and the remaining amount of powder. It can also be used to check whether the powder feeding device is normal.
Parameters of the powder feeder
Add a control valve and powder feeding tank on top of the original powder feeding system, which can continuously add powder to the upper tank during operation to achieve uninterrupted machine operation.
| Powder feeding amount (g/min) | 3-50 | 5-120 |
| Powder feeding motor | Stepper motor | Stepper motor |
| Powder feeding accuracy (%) | ≤5 | ≤5 |
| Powder storage filling capacity (kg) | 10 | 10 |
| Adapt to powder particle size (mesh) | 80-300 | 80-300 |
| Powder feeding air flow(m3/h) | 0.2-3 | 0.2-4 |
| Powder feeding pressure limit (MPa) | ≤0.4 | ≤0.4 |
| Powder feeding amount (g/min) | 3-50 | 5-120 |
The particle size of welding powder is not easy to be too large or too small, and it is advisable to use 80-200 mesh.
The powder sent out with too small particles is easy to blow away, leading to a decrease in the utilization rate of the powder.
Excessive particle size can easily cause blockage in the powder feeding channel of the welding gun, leading to the scrapping of the welding gun.
Before adding welding powder, it is necessary to filter with the provided sieve to avoid the above phenomenon.
