What to do with the malfunctioning spraying equipment

In the process of applying electrostatic coating equipment, the powder coating is not good every time it is started, and it will be fine if it continues to work for more than half an hour; the root cause: is an agglomeration of powder in the spray gun, after moisture absorption, the spray gun leaks electricity without powder coating, and long-term work generates heat After the tide is removed, the leakage of electricity is alleviated, and the ability to spray powder on the spray gun is improved. Suggestion: tidy up the powder attached to the spray gun table, and need to tidy up every time it is turned off to avoid powder accumulation and agglomeration.

The work indicator does not light up during the application of electrostatic painting equipment; the root cause: the cable socket of the spray gun is not good, the gun stroke is too short, and the switch in the gun cannot be pulled; suggestion: check the spray gun cable, adjust the trigger top screw;
The power indicator light does not light up during the application of electrostatic spraying equipment; the root cause: the power socket is out of power, the power cord and the socket are in poor contact, the power fuse is blown; suggestions: check the power supply and replace the power fuse.

There is no powder in the process of applying electrostatic coating equipment or powder is always produced as soon as it is vented; the root cause: there is water in the high-pressure air, and the working environment temperature is too low, the solenoid valve spool is frozen, and the feature is that the main engine work indicator flashes normally, the solenoid valve does not act (new discovery). Suggestion: Use a hairdryer to heat the solenoid valve, and properly handle the moisture and temperature phenomena.
Too much powder is produced during the application of electrostatic coating equipment; the root cause: the air pressure of the powder is too high, maybe the fluidization air pressure is too low; suggestion: adjust the air pressure properly;
In the process of applying electrostatic spraying equipment, the time of powder output is more or less; the root cause: the powder fluidization is abnormal, usually the fluidization air pressure is too low, and the powder is not fluidized; suggestion: adjust the fluidization air pressure.
