Powder coating machine,a epuiment for metal surface treatment.
Some people say when they do the paiting work,some problems will occur to the machine.What the problem?How it happen?and how to solve it?Let's see as below:

High –voltage display does not operated even after powder is on and trigger is pulled |
. Electric faulty-The electric line coming into CONTROL UNIT is not property connected . Faulty fuse and bad equipemnt on the part of external power source . .Faulty lamp. .Faulty printed circuit board(PCB) .Faulty line in GUN .Faulty in high-voltage generation part .Faulty trigger switch

The powder would not be fluidified |
.The fluidzing air hose is not connected or compressed air is not input . Faulty fluidizing plate . Faulty operation of pressure reduction valve |
.Connect after checking .Replace .Replace |
|
The gauge hands of CONVERYING AIR and DOSING AIR do not move during operation |
.operation mistake: The power switch is not pressed .The trigger is not pulled .Faulty SOLENOID valve .Faulty PCB |
. Turn on the power switch .Check while pulling the trigger . Replace |

The powder would not be ejected even after power switch is on and trigger is pulled |
.Blolckage generated in injector , check valve sleeve in the injector paint hose or GUN . worn-down sleeve .Poor fluildfying operation .CONVERYING AIR is not supplied. . Faulty air –adjustment valve . Faulty solenoud valve . Faulty PCB . Oil and moisture contained In the compressed air |
. Disassemboe and clean
. Replace .Replace .check above issues .Replace .Replace .Replace .Install an air dehydrator |
|
Powder is ejected from GUN but with its electrostatic intensity low |
.High-voltage assembly is low .Faulty GUN connector , wire and wire connector .Faulty PCB .Faulty high-voltage casecade .Faulty ROD holder |
.increase the voltage leverl .Replace the faulty part .Replace .Replace |
|
Powder ejection and electrostatic intensity is good , but its attach efficiency is poor |
.Faulty earth of powder object .Too much paint on the converyor hangar and powder object area .The high voltage pin caved in |
.Check the earth state .Remove powder from handar and powder-object area .Replace the rod holder |
