LOW-PRESSURE PART OF STEAM TURBINE WITH AXIAL OUTLET Russian patent published in 2003 - IPC

FIELD: turbines. SUBSTANCE: proposed low-pressure part is designed for steam turbine with axial outlet. Said low-pressure part is provided with axial outlet branch pipe connected through adapter with condenser is containing end face seal and bearing support of rotor. The latter are installed in support shell secured in outlet branch pipe by means of radial posts. in proposed low-pressure part upper half of support shell consists of two parts connected through flange joint between seal and bearing support, radial posts pass in zone of arrangement of bearing support and hatch is made in outlet branch pipe over end face seat. Pipelines to deliver steam to seal and suck steam-air mixture out of seal pass through lower half of outlet branch pipe being laid through pipes which form, together with round rods and bridges, streamlined profiles of radial posts. Housing of bearing support from side of condenser is provided with flange overlapped by hinged down cover. Second hatch is made over cover in outlet branch pipe. EFFECT: convenience of servicing of end seal in rotor bearing support without opening turbine cylinder. 4 cl, 3 dwg
