Electrostatic powder spraying gun, the key spraying equipment in powder spraying equipment, its main working principle is to use electrostatic spray gun high voltage generator to ionize the air around the powder spraying gun head to produce a negative electrostatic magnetic field, so that the powder is adsorbed to the workpiece with a positive electrode to be coated, which directly determines the quality of the workpiece coating, is the key factor that determines the level of the process.
Electrostatic spray gun mainly uses corona discharge electrostatic powder spray gun system to complete powder spraying. The system includes: 1) high voltage generator for electrostatic painting equipment (composed of high frequency transformer and booster circuit)，it’s electrostatic sprayer accessories : 2) corona discharge electrode (composed of needle electrode and ring electrode) : 3) spray regulator: 4) air and powder conveying pipeline. With the continuous development and innovation of spraying technology, high voltage generator for electrostatic painting equipment can now be installed inside the spray gun. The reduced power supply is switched on, converted into high voltage by a multi-stage booster, and applied to the corona discharge electrode or ring electrode at the end of the spray gun, so that the air around the electrode is ionized, and the grounded workpiece (generally the anode). Positively charged) to form an electric field. The powder coating is delivered from compressed air to the front of the gun. When atomized, the powder will carry a negative charge when passing through the electric field, fly to the surface of the workpiece under the action of the electric field force (electrostatic attraction) and compressed air, and adsorb on the workpiece.
Therefore, the work of the electrostatic spray gun is good or bad, and the internal electrostatic spray gun high voltage generator plays a very important factor. Tianwang has been developing electrostatic spray gun HV generator products for more than 8 years, and the produced high voltage generator for electrostatic painting equipment has the characteristics of static stability, good electrical conductivity, high safety and high powder rate. The company has a professional technical team and fully automated production line, the quality is strictly checked, so that you can rest assured of our cooperation!
