Abstract:
A high rotation atomizer functioning with inner charging includes a high-voltage circuit which generates a high voltage that can be applied to a bell cup, from a low voltage. This high-voltage circuit includes a measuring resistor in a circuit path between the turbine casing of the turbine driving the bell cup and ground. A first measuring voltage can be tapped at this first measuring resistor, which voltage is a measure for the voltage applied at the turbine casing. A second measuring resistor is placed in a circuit path between the turbine casing and ground. A second measuring voltage is tapped at this resistor, which is likewise a measure for the voltage applied at the turbine casing. If the information gained from the two measuring voltages deviates too strongly from each other, then the control device triggers an error signal. By this means, the safety of the entire system is increased.
Abstract:
An electrostatic atomizer for electrostatically coating a workpiece, in particular for coating vehicle bodies or parts thereof, with a coating material, having both an inner electrode and an outer electrode for electrostatically charging the coating material.
Abstract:
A nozzle head for a rotary atomiser for applying a coating material to an object includes a rotary bell, which is rotatable about an axis of rotation and has a breakaway edge and a discharge surface to which the coating material can be supplied in such a way that the coating material is spun off from the breakaway edge of the rotary bell. Coating material can be supplied to the discharge surface via a flow path. The flow path is divided in a delivery region into sub-paths, each having a delivery opening which is arranged eccentrically to the axis of rotation of the rotary bell and from which the coating material, which arrives from there at the discharge surface, can be delivered. A rotary atomiser having a nozzle head of this type is also described.
Abstract:
A bell plate is rotated about a rotational axis, and coating material is supplied to a discharge surface of the bell plate such that the coating material is projected away from the bell plate. A working fluid is blown at least temporarily as a transonic or supersonic flow onto the coating material coming from the bell plate by means of a dispensing device. Furthermore, a spray head for a rotary atomizer is provided for applying a coating material to an object, having a bell plate which can be rotated about a rotational axis and which has a discharge surface, wherein coating material can be supplied to the discharge surface such that the coating material is projected away from the bell plate. A dispensing device which can blow a working fluid at least temporarily as a transonic or supersonic flow onto the coating material coming from the bell plate.

Abstract:
An insulation device for a coating system for coating objects, the coating system having an electrostatically operating application apparatus having a dispensing device which dispenses a coating material, and at least one storage container which is connected to an input valve device via an inlet line and to the dispensing device via a supply line. The insulation device comprises a channel with a physical body which can move in the channel. The physical body has an electrically insulating material and can be moved by means of a fluid pressure between a park position and an insulation position and is designed such that, when it moves from the park position to the insulation position or from the insulation position to the park position, the physical body removes material from an inner casing surface of the channel, so that an electrical insulation path can be formed between the storage container and the input valve device.
