Main issues |
Causes |
Solution |
Powder blown out |
Too big air pressure fluidization |
Adjust and reduce air pressure |
Trouble in wind exhausting system |
Check wind exhausting system whether is jammed |
Powder volume is more than 2/3 of box in fluidization |
Reduce powder volume to 2/3 |
Too thin powder grain |
Reduce reclaiming amount, increase new powder ratio |
No air effusion from powder surface |
Too low air pressure |
Increase air pressure |
Jam of fluidization panel |
Check fluidization panel whether jammed |
Fluidization panel sheltered |
Check the bottom of case whether sheltered |
Powder solidifying |
Mannually loosen powder |
Bad fluidization |
Powder caking or wet |
1, Mannually loosen powder
2, Check contraction air humidity and oil content |
Fluidization panel sheltered |
Check the bottom of case whether sheltered |
Fluidization panel jammed |
Check fluidization panel whether jammed |
Little powder volume |
Adding powder to 2/3 of the case |
Granularity |
Control the newpowder and reclaiming powder composing |
Bad powder fluidization performance |
Contact powder supplier |
Jam of powder tube or pump |
Jam |
Clearing and change parts |
Too big air pressure |
Adjust or reduce air pressure of powder pump and gun |
Too wet contraction air |
Check air supplying system to get fresh air |
Powder supplying tube composing |
Check powder tube，Contact equipment factory |
Broken pump or spare part |
Change broken parts |
Powder Granularity |
Control the newpowder and reclaiming powder composing |
Powder type or prescription |
Contact powder supplier |
Tube bending, staving, knotting |
1, Avoid abrasion
2, Change powder tube |
Too long powder tube |
Reduce powder tube length |
Deficient powder |
Bad powder fluidization |
Refer to above solving methods |
Powder supplying system jam |
Check powder pump and gun |
Too long powder tube |
Reduce the length of powder tube |
Low air pressure |
Check air supplying system |
Broken pump |
Check and change broken part |
