SYSTEM SUPPLYING OIL TO BEARINGS OF TURBO-MACHINE Russian patent published in 2011 - IPC F01D25/18 

FIELD: machine building.

SUBSTANCE: system supplying oil to bearings of turbo-machine consists of oil pumps, main oil tank with frame filters, of pressure and drain collectors, pressure oil pipes with case-type welded-in boxes to each of bearings, of oil coolers, of accessories, and of drain oil pipes connecting carters of bearings with drain collector. Additionally, the system has by two moveable rotating boxes installed inside each case-type box by means of a control mechanism connected to a united system controlling flow of oil either instantly shutting it off, or instantly directing to drainage, thus facilitating alternative mode of operation according to a programme for washing the system of oil supply. The invention unites operational and repair circuits into a single system of oil supply to bearings of turbo-machine, facilitates uninterrupted supply of oil via pipelines meeting requirements of fire safety by density of compounds and facilitating improved quality and efficiency of after-repair washing.

EFFECT: automated drive for control of rotating mechanism of moveable boxes, which optimises washing and reduces time for pre-starting operations.
