1.Defective paint atomization or asymmetric fan size: replace the air cap / nozzle or there are impurities in the gun, electrostatic spraying equipment spray gun is generally treated by removing the gun and cleaning the internal air line. 2. Paint leakage of the pull rod above the trigger: the seal of the pull rod is worn, just replace the seal. Dongguan electrostatic spray gun generally avoids premature wear. 3.Gun tip dripping paint: gun needle and nozzle wear, need to replace needle wear, the way to avoid premature wear is: adjust the flow control button to the maximum; connect the paint regulator to adjust the paint flow through the voltage regulator to reduce the excessive pressure inside the gun; use high quality paint. Electrostatic spray gun, in addition to the above faults, there are motor bearing wear. During bearing replacement, pay attention to the air pressure not too high (0.4-0.55MPa), regular measurement of gun resistance reference recommendations, but also pay attention to paint resistivity.
