Turbine generator rotor lubrication control device

The invention relates to the technical field of generators, in particular to a steam-turbine generator rotor lubrication control device which comprises a steam-turbine generator shell and a rotor rotationally installed in the steam-turbine generator shell, a lubrication assembly is arranged at the top of the steam-turbine generator shell, and an oil collection assembly is arranged at the bottom of the steam-turbine generator shell. The oil collecting assembly is used for collecting and filtering dripping lubricating oil generated when the lubricating assembly lubricates a rotor, and an oil return assembly is arranged between the lubricating assembly and the oil collecting assembly and used for returning the lubricating oil filtered by the oil collecting assembly to the lubricating assembly to be recycled. According to the lubricating device, an oil port sealing cover does not need to be repeatedly opened on the turbonator shell by personnel, the workload of maintenance personnel is reduced, the turbonator rot
