MULTI-PURPOSE TURBO-GENERATOR SET Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: airtight body of turbo-generator set accommodates two turbine runners, as well as pump and compressor wheels secured in cantilever way to output ends of shaft rotating in supports. Supports are made in form of plain radial thrust bearings. Complex aggregation of compressor and pump parts extends range of turbo-generator set application in refrigeration engineering. Provision of turbo-generator set with system of lubrication and cooling of supports by liquid cooling agent makes it possible to use no gas-static supports which perceive vibration loads badly and to include hydrodynamic plain bearings which showed themselves to advantage. They possess proper damping capacity and enhance vibration resistance of supports. The above-indicated lubricating and cooling system is made as hollow circular casing positioned inside body and coupled to plain radial thrust bearings by means of axial radial channels. EFFECT: extended range of application. 1 dwg
