Maintenance of manual electrostatic spray gun

In order to protect the safety of the spray gun, the resistance of the spray gun, the resistance of the power supply and the resistance bar of the spray gun must be tested within a certain period to confirm whether they are in good condition and whether the seals are complete or not In case of any problem, timely handle or replace the parts In order to ensure the spraying effect of the spray gun, the voltage, flow, fog amplitude and spraying effect should be tested regularly The voltage can be tested by special instrument to confirm whether it meets the use requirements; check whether the electrode needle is in good condition and should be fully discharged; if there is a fault, replace the corresponding parts in time; for the spray gun of the built-in generator, check the performance of the generator frequently After each spraying, the internal pipes and gun caps of the spray gun shall be cleaned to ensure that the internal pipes are unblocked and the spray gun is clean Pay attention not to damage the air hole of the gun cap, not to mention the electrode needle The solvent used for cleaning shall be non-conductive solvent.
