| titleOfInvention | Nuclear reactor coolant pump and its passive parking seal assembly |
| abstract | The invention discloses a kind of nuclear reactor coolant pump and its passive parking seal assembly.Passive parking seal assembly includes sealing ring, tightening ring and fusible support block；Sealing ring is split ring, and under nominal situation, sealing ring keeps gap with opening around pump shaft and with pump shaft；Tightening ring is enclosed on the periphery wall of sealing ring, its under station blackout operating mode to sealing ring provide it is enough big ground enclasping force, drive sealing ring close holding pump shaft；Fusible support block is in the opening of sealing ring or tightening ring, and ring is closed and ensures that sealing ring is in opening where it is prevented in normal conditions, and fusing is failed and sealing ring is closed in the presence of tightening ring under station blackout operating mode.Compared with prior art, passive parking seal assembly of the present invention only has three elements, axle envelope integrity demands that can not only be when meeting station blackout operating mode under conditions of independent of emergent axle envelope injected system, and with the advantages of simple in construction, sealing is firm. |
