3 Terms and Definitions

The terms and definitions defined in GB/T 3836.1 and the following terms and definitions apply to this document. 3.1 A spray gun that uses electrostatic working principle to spray liquid and powder coatings. Note 1.Typically includes the housing, electrostatic discharge device, mist control device, paint channel, air channel, high-pressure generator (built into the spray gun), and adjusting manipulator. Structure, etc. Note 2.When the high-pressure generator is built into the spray gun, it is considered part of the spray gun. Note 3.Electrostatic spray guns include electrostatic paint spray guns and electrostatic powder spray guns. 3.2 auxiliary device The necessary auxiliary equipment for supplying and controlling the working voltage, current, and atomizing coating of electrostatic spray guns. Note 1.Typically includes a spray gun controller, a high-pressure generator (external to the spray gun), a paint atomizing device, a paint supply device, high and low voltage cables, and a drive motor. And pneumatic motors, etc. Note 2.When the high-pressure generator is externally mounted on the spray gun, it is classified as part of the auxiliary device. 3.3 spray gun controller A device for controlling the high-voltage electrostatic output of an electrostatic spray gun and for coating spraying. 3.4 low voltage cable The high-voltage generator contains a built-in spray gun with a cable for connecting the electrostatic spray gun and the spray gun controller. ...
