METHOD FOR OPERATING A ROTARY ATOMIZER, SPRAY HEAD, AND ROTARY ATOMIZER WITH SUCH, A SPRAY HEAD

摘要

The invention relates to a method for operating a rotary atomizer with which a coating material is applied onto an object. A bell plate (8) is rotated about a rotational axis (18), and coating material is supplied to a discharge surface (34) of the bell plate (8) such that the coating material is projected away from the bell plate (8). A working fluid is blown at least temporarily as a transonic or supersonic flow onto the coating material coming from the bell plate (8) by means of a dispensing device (70). Furthermore, a spray head for a rotary atomizer is provided for applying a coating material to an object , comprising a bell plate (8) which can be rotated about a rotational axis (18) and which comprises a discharge surface (34) , wherein coating material can be supplied to said discharge surface such that the coating material is projected away from the bell plate (8). A dispensing device (70) which can blow a working fluid at least temporarily as a transonic or supersonic flow onto the coating material coming from the bell plate (8). The invention further relates to a rotary atomizer with such a spray head.
