Coating materials requirements in the appearance of increasingly high With the social development . Electrostatic coating technology that is at home and abroad in recent years with the rapid development of new technology, has been widely applied to various industrial fields. The use of electrostatic spray technology developed by Electrostatic Oiler is a mechanical, hydraulic, electrical, high voltage static electricity, computer-controlled high-tech products in one.Electrostatic Oiler in the structure and research base atomization process, in order to find a different voltage, flow under the effect of liquid atomization and atomization of the law, citing the Wuhan University of Science and Technology of Electrostatic Oiler Experimental Study Group, revealed through the experimental phenomena Oil of the essential characteristics of electrostatic atomization.In this paper, the analysis of the pilot based on the Oiler part of the jet and droplet spread of done a theoretical analysis and calculation. In which some of the main jet on the jet made a non-linear stability of EHD (electric fluid dynamics) analysis, have been in the cone-jet mode the jet broken out after the split of the two main droplets, that is the main droplet and minor proportion of the particle size of the droplets. Will be calculated by the main and secondary droplet droplet size ratio and the experimental results were compared to verify the theoretical analysis.Proliferation in the droplet of the article on the jet to split out the different fragmentation of the charged particle droplet movement in the division done a theoretical analysis of the situation, and will charge a different coefficient, jet flow, voltage, case size of the Netherlands Xinhua droplets compared the proliferation of so has been the application of the value of a certain calculation model.
