company news about Common faults and solutions in electrostatic spray coating production lines

Common faults in electrostatic spray coating production lines include:

1. Uneven Coating
Causes:

Spray gun malfunction or blockage
Incorrect paint viscosity
Insufficient static voltage
Solutions:

Check and clean the spray gun
Adjust the viscosity of the paint
Check and adjust the static voltage
2. Poor Adhesion of Coating
Causes:

Unclean workpiece surface
Quality issues with the paint
Incorrect spraying angle
Solutions:

Ensure the workpiece surface is clean and free of oil and dust
Replace or test the paint quality
Adjust the spraying angle and distance
3. Bubbles During Spraying
Causes:

Uneven mixing of paint
Air mixed into the paint
Solutions:

Ensure the paint is thoroughly mixed
Avoid air mixing in while adding paint
4. Static Failure
Causes:

High-voltage power supply failure
Damaged insulation parts
Solutions:

Check the high-voltage power supply and its connections
Replace damaged insulation components
5. Excessive Noise from Equipment
Causes:

Mechanical wear
Paint pump failure
Solutions:

Check and replace worn parts
Inspect the pump’s operating condition and perform maintenance
6. Incomplete Drying
Causes:

Incorrect temperature settings in the drying equipment
Poor ventilation
Solutions:

Adjust the drying equipment's temperature and time
Ensure good ventilation in the drying area
Regular maintenance and inspection of the electrostatic spray coating production line can effectively reduce the occurrence of faults and improve production efficiency.
