Mixed-flow pump turbine structure

2018 - form of mixed-flow pump turbine structure 10 - 03 pumped storage power station form and conventional electric generator units are basically the same, according to the arrangement of thrust bearing structure divides the whole umbrella ( Thrust bearing arrangement on the roof, two bearing) , half umbrella ( Of the thrust bearing arrangement on a rack) , half umbrella ( Of the thrust bearing arrangement on a rack) 。 A, all umbrella type thrust bearing is decorated in the turbine on the roof, only two bearings. After the mechanical switch, all supported by the top unit. Two and a half, umbrella ( Of the thrust bearing arrangement on a rack) Of the thrust bearing arrangement on a rack, and guide bearing formed a system. After the mechanical switch, the unit by the next frame bearing the weight, is passed on to the turbine machine machine pier. Three, suspension thrust bearing arrangement in a computer rack, and guide bearing on form a system. After mechanical switch, chassis, stator bearing rotating parts by weight. According to wheel installation partition: disassembly type under the wheel, wheel in the demountable type and the detachable type 1 wheel, wheel in the demountable type 2, wheel under the demountable type 3, detachable type on the wheel
