[0002] The electrostatic oiler utilizes a high-pressure and high-speed rotating turbine atomizer to atomize oil droplets and spray them accurately and evenly onto the surface of the strip, which plays a role in corrosion protection and lubrication. The metering pump is driven by a servo motor and the oil is transferred to the rotating atomizer at a given speed by the PLC. Usually, the metering pump and the servo motor are driven by gears.
