在油液带电的静电涂油机中，接高压直流电源负极的刀形喷油梁与接地的带钢（或钢板）之间产生高压静电场，从喷油梁刃口狭缝中流出的油液直接带电，在强电场中雾化后吸附在带钢（板）表面上，实现“静电涂油”。喷油梁结构型式与直流电源输出电压是影响静电涂油的主要因素。 In the oil-charged electrostatic oiler, the high-voltage electrostatic field is generated between the knife-shaped fuel injection beam connected to the negative pole of the high-voltage DC power supply and the strip (or steel plate) grounded. Oil flowing out of the slit of the fuel injection beam edge Liquid directly charged in the strong electric field after atomized in the strip (plate) surface, to achieve “electrostatic oiling.” Fuel injection beam structure and DC power output voltage is the main factor affecting the electrostatic oiling.
