Safe operation procedure of electrostatic precipitator?

1. Before powder spraying, check whether all equipment, such as circuit connectors, spraying devices and grounding wires, are in good condition. 2. Before spraying, the drying furnace should be turned on for preheating, and the exhaust fan in the spraying room should be turned on. 3. The high-voltage cable should keep a distance of more than 500mm from other power lines to prevent breakdown and discharge. 4. Turn all the switches of the high-voltage generator to the "off" position, then turn the main power switch on the voltage generator to the power switch with a voltage of 220 volts first, and then turn it to the power switch with a voltage of 380 volts after the green light is on for 30 minutes. Start the high voltage button at this time, and gradually raise the voltage to the required high voltage after the red light is on. 5. During electrostatic spraying, the operator shall not leave the workplace and shall not approach electrostatic spraying at will. 6. There shall be no open flame in the electrostatic spraying room, and non-working personnel shall not enter around the spraying room. Fire fighting equipment shall be provided. 7. It is forbidden to transfer objects in a strong electric field. When working, the operator should not touch the insulation material and power supply. 8. The distance between the nozzle and the workpiece should not be less than150 mm.. 9. There is noise when painting, changing paint, observing the paint surface of the workpiece and spraying. When the electrical equipment fails or the work ends, the power supply must be cut off immediately and discharged with the grounding rod.
