Abstract
1398157 Cooling dynamoelectric machine rotors WESTINGHOUSE ELECTRIC CORP 9 Aug 1972 [21 Sept 1971] 37154/72 Heading H2A In a dynamoelectric machine, e.g. large turbine generator, whose rotor 20 has passages through which circulates a liquid coolant, e.g. water, and which include an axial passage 44 communicating with opposed radial passages 40 extending to the rotor surface to discharge the liquid therefrom, there is provided in each radial passage a flow restrictor which regulates the liquid flow therethrough and discharges the liquid in a non-radial direction approaching the tangential and opposite to the rotational direction of the rotor. As shown, the restrictor is a stainless steel or other corrosion resistant material plug 48 having a curved discharge orifice 49 which converges in diameter towards its discharge end 50 whereby the centrifugal pumping effect and vibration of the discharging liquid are reduced. The plug may receive a vent tube 51 as claimed in Specification 1,398,158. Otherwise the generator is conventional, generally as is disclosed in Specification 1,340,290.
