ABSTRACT:
The invention relates to a method for operating a drive unit for a conveyor system, in particular for a chain conveyor drive with at least one driving machine and at least one hydrodynamic clutch. The hydrodynamic clutch can be filled with operating medium in which, during continuous operation, the operating medium is guided in a closed circuit. The circuit includes an inlet line associated such that the operating medium losses in the circuit are compensated for and in which the temperature in the closed circuit is ascertained and compared with a permissible temperature value. The invention includes the feature that upon exceeding an permissible temperature value in the closed circuit, the inlet line and the outlet line are simultaneously connected in the circuit for the purpose of volumetric cooling.
