A ) electricity has no reaction, the host panel indicator light is not bright.
Check if the power socket has electricity, the power plug is plugged in. The power switch is turned on, the multimeter measuring the ohm grade power line two plug resistance should be in the tens of ohms around, if the resistance greatly, illustrate the power line or a power switch is damaged, the replacement can be.
Two) open gun switch has no reaction, no current, no powder.
Check gun switch plug and socket good host. Pull out spray gun switch plug, a spray gun three core aviation plug with a multimeter ohmmeter Volume II the GRAPPLERS gun switch, control line is good, if not, whether gun switch ( or plug ) control line. ( seven core aviation plug of the switches, five core of the aviation plug for switching. )
Three) shot with powder, powder, no voltage and current.
1: check the current regulating potentiometer are closed.
2: check the gun control line plug is plugged in.
3: check the ground line is connected, the workpiece is grounded, the host ground and spraying room sharing a single wire.
Spray gun open the rear cover to disconnect the high voltage module two lines, turn on the power switch button spray gun with a multimeter DC voltage retaining amount disconnect the two lines are about 19 volts; without the circuit board damage. ( five core, seven core wire is also so. )
Four) is current, no shot powder or flour small discontinuities.
1: check the powder box powder amount enough, powder box should be higher than the suction straw powder.
2: check the air pressure is normal, the input air pressure should be in 0.4MPa～ 0.7MPa constant.
3: flow is normal, good flow should be to make the powder box powder just in a boiling state, with the hand in a powder box stir not feel no large amount of powder leakage resistance.
4: listen carefully at the time of the shooting without attracting of the electromagnetic valve noise, such as no may be a solenoid valve control circuit or the control relay fault.
5: to set in powder supply pump spray powder tube removed, shot look for powder pump mouth without powder, and whether it is normal, if the normal the gun powder tube blockage or gun head plugging, plugging must use high pressure gas to blow it, aging must change to a new.
6: if the powder supply pump is a powder or a powder is not normal, should put the powder supply pump, a powder feeding pipe down to check whether there is a blocking phenomenon, powder supply pump core is worn, the normal size should be 5.5 mm; powder supply pump inlet nozzle is blocked, the corresponding sealing rubber ring is damaged leakage.
7: the concentration of gas is set too big.
Five) boot electricity immediately after the burning machine power supply safety.
Power line damaged or burned-out transformer short circuit short circuit.
Six) static high voltage electric hand.
Check whether the workpiece and spraying chamber and the good earth.
Spray gun on the grounding piece is host to pass.
Spray gun head discharge pin break or electric block.
The spray gun body powder too much or the module itself aging breakdown.
Seven) high electrostatic voltage low
Module output end electrically blocking, with air interval discharge to.
Air wet electrostatic high voltage will decrease |
