    the use of the gun in the process of sometimes some problems, is now on the phenomenon of spray gun to carry out a detailed analysis, and according to the phenomenon of the analysis of the cause, to find a solutionphenomenon: the spray shape is center of gravity to one side
    reasons: air cap center hole or atomization hole blockingcountermeasures: 1, cleaning atomized cap2, replacement of atomized capphenomenon: left or rightcause: 1, air cap side of the fan control hole blocking
    2, air cap damage
    countermeasures: 1, cleaning atomized cap2, replacement fog capphenomenon: spray over theReason: 1, spray paint viscosity is too high
    2, spray pressure is too low
    3, nozzle caliber and thimble due to wear and increase and become smaller
    countermeasures: 1, reduce the coating viscosity2, increase the spray pressure
    3, replace nozzle set phenomenon: spray spread
    cause: 1, paint viscosity is too low
    2, spray pressure is too high
    3, fan control hole large 5, atomized air channel blocking countermeasures: 1, turn up the coating viscosity 2, lower spray pressure
    3, replace the nozzle set
    4, add enough paint
    5, clean the air passage of the gun phenomenon: jump gun cause: 1, nozzle not tightened or not installed
    2, gun needle seal kit loose
    3, gun connection nut loose (under the kettle gun) 4, pot paint Insufficient 5, nozzle set damage
    countermeasures: 1, tightening nozzle or cleaning and installation of nozzle set
    2, fastening thimhole sealing kit
    3, tightening connection nut 4, supplemental coating 5, replacement nozzle set phenomenon: spray weight or weight cause: 1, nozzle, thimble or air cap air outlet on the air outlet of debris blocked
    2, air cap or damaged nozzle
    countermeasures: 1, Clean nozzle set 2, replacement nozzle set phenomenon: spray paint or a small amount of paint reasons: 1, the gun pot lid of the air supplementhole blockage or air cap and suction pipe seriously blocked
    2, no paint in the pot
    3, the thimble stroke is too small
    countermeasures: 1, clean the lid of the air supplementhole, air cap and suction tube
    2, supplemental paint 3, rotating paint flow control knob increase the flow of the valve : Nozzle leakage coating reasons: 1, thimble seal nut is too tight
    2, nozzle port inside the foreign body
    3, nozzle and thimble does not match or have damage
    4, thimble injection spring broken or not installed countermeasures: 1, spin-pin pin sealed nut
    2, cleaning nozzle 3, replacement nozzle set 4, replacement of the top pin spring or install the top pin spring : Spray can not adjust the reasons: 1, air cap on both sides of the fan control hole blocked
    2, spray adjuster damage or install the wrong 3, spray gun fan control hole air channel blocking countermeasures: 1, clean air cap
    2, replace the spray adjuster or correctinstallation of the spray adjuster 3, clean air passage phenomenon: can not normally adjust the air pressure or just on the compressed air air will be directly Or air valve damage
    2, air valve return spring 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 coating cause: 1, thimble seal wear
    2, thimble gasket not installed
    3, thimble gasket damage or not installed
    5, the contact between the thimble and the seal ring wear 6, the thimble and the spray gun do not match the countermeasures: 1, replace the thimble seal ring
    2, add the thimble seal gasket
    3, replace or add the thimble seal seal spring 4, tighten the pin seal cap
    5, replace the nozzle set 6, replace the nozzle with the spray gun matching nozzle
