Pumped storage power station exchange 2019 - thrust bearing structure
03 -
Thrust bearing is one of the most core components of the energy storage generating units, its working conditions directly affect the safe and reliable operation of the unit.
At present the common support structure pumped storage generator thrust bearing main elastic tank (
GX issue)
, elastic plate (
GX phase ii)
And elastic column (
HX）
, spring cluster (
QX)
Four kinds of structure.
Spring support clusters there are three kinds of thrust bearing structure by means of the basic types: the first kind, cluster that helical spring precompression, such as: THP pumped storage power plant;
Second, pre compression type disc spring beam, such as the XY pumped storage power station, the third, no cluster that spring precompression, such as west order of pumped storage power station, qingyuan pumped storage power station.
QY pumped storage units without preloading spring support thrust bearing the Toshiba technology clusters, early spring cluster support with manufacturers such as GE, are to be of a single assembly preload.
For simple, reliable, nearly 30 years ago developed without prestressing technology, after that Toshiba's pump and conventional storage thrust small spring not be preloaded.
Compound rubber pad support small tank backbone screw spring support beam elastic tray supported flexible disc
