Test spray gun CQ-SJ5
1、 Local features:
1. Specially spray on blind spots (no matter how large the blind spots are, powder can be evenly applied);
2. The output voltage is displayed digitally;
3. Triple protection function (overvoltage, overcurrent, and ultra-high voltage protection);
4. Metal powder can be sprayed without any modifications;
5. The high-voltage module is adjacent to the nozzle, with low voltage loss;
6. The powder coating rate is extremely high, saving at least 30% of powder compared to ordinary spray guns, and can double the spraying speed;

4、 Installation and Debugging:
1. Place the device near the spray chamber;
2. Insert the circular plug of the power cord into the power socket on the back of the control box, and connect the other end to the power supply;
3. Fix one end of the grounding rod on the back of the control box, and connect the other end to the grounding wire reliably, and connect it to the workpiece and spray chamber;
4. Connect the compressed air that has been dried and degreased to the air source interface on the back of the control box;
5. Insert the spray gun cable plug into the gun cable socket on the back of the control box;
6. Connect the air pipe on the spray gun to the air pipe interface on the back of the equipment;
7. Connect the cleaning gun to the cleaning gun interface on the back of the device;
8. Connect the gas source and adjust the flow tuning knob on the front of the device appropriately. The flow tuning knob should be turned clockwise to small and counterclockwise to large
9. Connect the power supply and turn on the power switch on the control box
After pulling the trigger, the digital display shows the actual high pressure, which automatically changes with the spraying distance. The voltage for spraying ordinary parts should be increased to a suitable level,
When spraying complex workpieces, the voltage should be lowered to an appropriate level, and the high voltage should not be set too high during long-term work
5、 Reason and solution for malfunction:
|
symptom
|
reason
|
countermeasure
|
Unstable powder production
|
Insufficient gas supply flow
|
Increase the inner diameter of the gas supply pipeline
|
|
The pressure fluctuation of the gas source is too large
|
Adjust the gas source pressure to stabilize it
|
|
Powder tube and gun inner tube are blocked
|
Clean the powder tube and gun inner tube
|
|
Dilution pressure too low
|
Adjust the dilution pressure
|
|
The spray gun cannot stop continuously producing powder
|
The solenoid valve is damaged
|
Replace the solenoid valve
|
|
The solenoid valve is sometimes good and sometimes bad
|
Open the solenoid valve, clean the internal debris, and make it move flexibly
|
Spray gun leakage
|
Poor grounding of equipment
|
Ensure good grounding of the equipment
|
|
The interior of the gun is blocked by metal powder
|
Clean the gun barrel
|
|
Ash and pollutants on the surface area of the gun
|
Clean the surface of the gun body
|
|
Staff not grounded
|
When using gloves and insulation, it is necessary to ensure that the operator's body is connected to the grounding plate of the gun
|
|
Can spray, but has weak static electricity
|
Poor contact between the nozzle guide rod and the high-pressure output point inside the nozzle
|
Make it in good contact
