In the process of using the spray gun, some problems sometimes occur. Now we will analyze the phenomenon of the spray gun in detail and analyze the cause of the phenomenon to find a solution.
Phenomenon: The shape of the spray pattern is biased toward one side of the center Cause: Air hole in center hole or atomization hole is blocked.
1, clean atomization cap
2, replace the atomization cap
Phenomenon: Left or right:
1, the air cap side of the fan control hole plugging
2. Air cap damage measures: 1. Clean atomization cap 2. Replace atomization cap
Phenomenon: The center of the spray pattern is too thick:
1, spray coating viscosity is too high
2, spraying pressure is too low
3, the nozzle diameter and thimble increase and decrease due to wear Countermeasures: 1, lower the viscosity of the paint 2, increase the spray pressure 3, replace the nozzle set
Phenomenon:Spray splitting
Reasons: 1, coating viscosity is too low
2, spraying pressure is too high
3, fan control hole diameter is too large
4, not enough paint
5, atomization air channel blockage measures: 1, increase the viscosity of the paint 2, reduce the spraying pressure 3, replace the nozzle set 4, add enough paint 5, clean the air channel of the spray gun
Phenomenon: Jumping Gun
Causes: 1. The nozzle is not tightened or not installed
2, loose needle seal kit
3. Loose connection nut of spray gun (lower spray gun)
4, lack of paint in the pot
5, nozzle set damage measures: 1, tighten the nozzle or clean and install the nozzle set 2, tighten the thimble sealing kit 3, tighten the connection nut 4, add paint 5, replace the nozzle set
Phenomenon: spray on the weight or weight
Causes: 1. Nozzles, thimble, or air caps have clogged air outlets
2, air cap or nozzle damage measures: 1, clean nozzle set 2, replace the nozzle set
Phenomenon: No paint or a small amount of paint
Causes: 1. The air refill hole of the gun lid is clogged or the gas cap and suction tube are seriously blocked
2, no paint inside the pot
3, thimble stroke is too small Countermeasures: 1, clean the lid of the air to add holes, gas caps and suction tube 2, add paint 3, rotating paint flow control knob to increase the needle valve stroke
Phenomenon: Leaking paint at the nozzle
Reasons: 1, the thimble seal nut is too tight
2. Nozzles inside the nozzle port
3, nozzle and thimble do not match or have damage
4, thimble return spring broken or not installed countermeasures: 1, unscrew the thimble seal nut 2, clean nozzle 3, replace the nozzle set 4, replace the thimble return spring or install the thimble return spring
Phenomenon: Spray width cannot be adjusted
Causes: 1. The control holes on both sides of the air cap are blocked
2, spray regulator is damaged or installed wrong
3. The air passage blocking of the control surface of the spray gun fan control measures: 1. Clean the air cap 2. Replace the spray adjuster or properly install the spray adjuster 3. Clean the air passage
Phenomenon: The air pressure cannot be adjusted normally or the compressed air can be directly sprayed from the muzzle
Causes: 1. Air conditioner damaged or air valve damaged
2, air valve return spring is broken or not installed countermeasures: 1, replace the air regulator or air valve 2, replace the air valve return spring or install the air valve return spring
Phenomenon: thimble seal leakage paint
Reason: 1, thimble seal worn
2, thimble seal ring pad is not installed
3, thimble seal spring damage or not installed
4, the top needle seal nut loose
5, the thimble and the seal contact wear
6, thimble and spray gun does not match measures: 1, replace the thimble seal ring 2, install the thimble seal gasket 3, replace or install the thimble seal spring 4, tighten the thimble seal nut 5, replace the nozzle set 6, replace and Spray gun matching nozzle kit is attached with "spray gun nozzle kit disassembly order" Disassembly sequence: thimble → gas cap → nozzle installation sequence: nozzle → gas cap → thimble If you do not follow the above order of disassembly, will result in damage to the nozzle kit ~ ~ If the above method can not help you solve the problem, you can contact us, we will be happy to serve you! ! !
