静电涂油是国际上近几年才出现的新方法。武汉钢铁学院机械系经过理论探讨和试验研究,已于1989年5月研制成功静电涂油机的关键部件——喷油刀梁,并用新开发的喷油刀梁及供油系统配用现成的国产高压静电电源,成功地完成了钢板表面涂防锈油试验。 1.静电涂油机的组成及基本原理 静电涂油机由高压静电电源、密封式喷油室、供油系统、电控系统及操作台组成。喷油室内装有上、下喷油刀梁,钢板(带)在相距很远的两刀梁之间自由通过。当高压静电电源输出直流小电流高电压,加在喷油刀梁与钢板(带)之间时,高压静电场使空气产生电晕放电,并使油液带电,从而形成薄纸状油雾,连续均匀地喷涂在钢板两面。喷油量可随机组(即钢板)运行速度和要求的涂膜厚度自动调节。 Electrostatic oiling is a new method that appears in the world in recent years. Mechanical Department of Wuhan Iron and Steel Institute after theoretical discussion and experimental research, in 1989 May successfully developed the key components of the electrostatic oiler - injection blade beam, and with the newly developed injection blade beam and fuel supply system with ready-made Domestic high-voltage electrostatic power, successfully completed the steel surface coated with anti-rust oil test. 1. Composition and basic principles of electrostatic oiler Electrostatic oiler by the high-voltage electrostatic power, sealed fuel injection room, fuel supply system, electronic control system and console components. The fuel injection chamber is equipped with upper and lower fueling blade beams, the steel plate (band) freely passing between two blade beams far apart. When the high-voltage electrostatic power output DC low current high voltage, coupled with the injection blade beam and steel (with), the high-voltage electrostatic field to produce air corona discharge, and the oil charged to form a thin paper-like oil mist, Continuous spraying evenly on both sides of the steel plate. The amount of fuel injected can be randomized (ie steel) operating speed and the required thickness of the coating is automatically adjusted.
