2.1. Air purging

 

1)    Explosion accidents are highly likely to occur in the vicinity of the operating space of the painting robot because of the presence of paint and air, which are flammable substances, and motors, which are ignition sources. Therefore, the painting robot has an explosion-proofing procedure for preventing explosion accidents.

2)    The Hyundai painting robot features a pressure explosion-proof structure for preventing flammable gas from penetrating into the robot body. This structure maintains the inside pressure of the robot body higher than the atmospheric pressure. Air purging refers to a series of procedures for preventing gas penetration by maintaining a constant pressure inside the robot body upon the initial application of power supply to the robot.

3)   After the power is switched on, the Hyundai robot controller automatically carries out air purging while the power supply to the motor of the painting robot is blocked. During air purging, the motor cannot be switched on even when you press the “Motor on” button. Do not manipulate it, and wait until the air purging is completed.
