应用：核电站的反应器冷却剂再循环（PWR）。KSB生产的RERS已在世界各地的大多数核电站使用，包括ISAR 2，德国，帕洛佛得角，美国，巴西，巴西，秦山1，中国，乌尔亨，韩国，巴拉卡，AUE等. RER is KSB’s classic four bearing design RCP, featuring flexible connection between motor and pump, independent dynamic characteristics of pump and motor rotors and low vibration of pump set. In addition, it has the following advantages: Ø 100% tightness l Improved 3 mechanical seals (double-redundant) plus 2 standstill seals to withstand the SBO condition Ø Integrity under upset conditions l Cooling of mechanical seals through thermosyphon effect l Newly-developed Passive Thermal Control Valve to ensure integrity of primary loop through closing control leakage line in several minutes without any supply of power or nitrogen under SBO condition Ø Operational safety l Medium-lubricated guide bearing Ø Perfect rotor alignment l Through Hirth-type serration of connections Ø Optimized hydraulics l Tailor-made impeller/diffuser combination l Model and full-load performance tests
