Problems and solutions of electrostatic spray gun for hardware

Special electrostatic spray gun can have hardware problems and solutions: (HONGDA professional analysis, countermeasures)

Spray gun in the process of use, sometimes there will be some problems, now the spray gun appear in the phenomenon of detailed analysis, and according to the emergence of the phenomenon analysis, find out the solution.

Phenomenon: the shape of spray is inclined to one side

Reason: gas head central hole or atomizing hole jam

Countermeasures: 1. Clean atomizing cap

2. Replace the atomizing cap

Phenomenon: left or right

Reason: fan control Kong Dusai 1, one side of the gas cap

2, gas cap damage

Countermeasures: 1. Clean atomizing cap

2. Replace the atomizing cap

Phenomenon: the center of the spray is too thick

Reason: 1. The coating viscosity is too high

2, spraying pressure is too low

3. The caliber and the thimble of the nozzle increase and decrease due to wear

Countermeasures: 1. Lower the viscosity of the coating

2, increase the spraying pressure

3, replace nozzle set

Phenomenon: jet splitting

Reason: 1, paint viscosity is too low

2, spraying pressure is too high

3, the fan control hole diameter is too large

4, paint is not enough

5. Blockage of atomizing air passage

Countermeasures: 1. Increase the viscosity of the coating

2. Lower the spraying pressure

3, replace nozzle set

4. Add enough paint

5. Clean the air passage of the spray gun

Phenomenon: jump gun

Reason: 1, the nozzle is not tightened or not installed

2, gun needle seal loose

3. The loose nut of the spray gun (lower pot spray gun)

4, insufficient paint in pot

5, nozzle set damage

Countermeasures: 1. Tighten the nozzle or clean and install the nozzle set

2. Fastening thimble sealing kit

3, tighten the connecting nut

4, supplementary coating

5, replace nozzle set

Phenomenon: heavy or low weight on the jet

Reason: 1. The air outlet of nozzle, thimble or air cap has sundries jam

2. Damage of gas cap or nozzle

Countermeasures: 1. Clean nozzle set

2, replace nozzle set

Phenomenon: spray paint or a small amount of paint

Reasons: 1. The air hole of the gun lid is blocked or the gas cap and the suction pipe are seriously blocked

2, there is no paint in the pot

3, the ejector stroke is too small

Countermeasures: 1. Air supplement holes, gas cap and suction pipe on the cleaning pot cover

2, supplementary coating

3, rotate paint flow control knob to increase the needle valve stroke

Phenomenon: leakage paint at nozzle

Reason: 1, the thimble sealing nut is too tight

2, the nozzle port inside the foreign body

3, nozzle and thimble does not match or damage

4. The thimble return spring is broken or not loaded

Countermeasures: 1, unscrew the thimble sealing nut

2. Clean nozzle

3, replace nozzle set

4. Replace the thimble return spring or install the spring with the upper thimble return

Phenomenon: the spray amplitude can not be adjusted

The reason: Kong Dusai 1, on both sides of fan control gas cap

2, the spray regulator is damaged or wrong installation

3, air gun fan control hole blocking channel

Countermeasures: 1. Clean gas cap

2. Change the spray amplitude regulator or install the jet adjuster correctly

3 clean air passages

Phenomenon: the air pressure can not be adjusted properly or the compressed air is connected directly, and the gas will be ejected directly from the muzzle

Reasons: 1. Damage of air conditioner or air valve

2. The air valve return spring is broken or not installed

Countermeasures: 1. Replace air conditioner or air valve

2. Replace the air valve return spring or install the air valve return spring

Phenomenon: leakage coating of thimble seal

Reason: 1. Grinding of thimble seal ring

2, the thimble gasket is not installed

3, the thimble sealing ring spring damage or not installed

4, the thimble sealing nut loose

5, the thimble and the sealing ring contact wear

6. The thimble is not matched with the spray gun

Countermeasures: 1. Replace the thimble sealing ring

2. Install gasket with thimble gasket

3. Replace or install the spring of the thimble sealing ring

4, tighten the thimble sealing nut

5, replace nozzle set

6. Replace the nozzle set matching with the spray gun

Assembly sequence of spray gun nozzle set

Disassembly order: thimble, gas cap, nozzle

Installation sequence: nozzle, gas cap, thimble

If not in accordance with the above order of disassembly and assembly, will lead to damage to nozzle set

Spray gun in the process of use, sometimes there will be some problems, now the spray gun appear in the phenomenon of detailed analysis, and according to the emergence of the phenomenon analysis, find out the solution.

Hardware special electrostatic spray gun preferred HONGDA electrostatic spray gun, professional, trustworthy.
