Description

Parameters influencing the pump performance were analysed during stationary and instationary conditions of an original DWR-heat removal pump, which was equipped with special measurement devices. The most important results will be presented by the following: 1) air addition deteriorates pump performance; 2) increasing system temperatures improve cavitation behaviour; 3) instationary tests lead to hysteresis phenomena; 4) pump performance was good within the tested parameter region.

Abstract (German)

Mit den Versuchen an einer originalen Nachkuehlpumpe einer DWR-Anlage, die messtechnisch besonders ausgestattet war, wurden einzelne, das Betriebsverhalten beeinflussende Parameter unter stationaeren und instationaeren Randbedingungen analysiert. Als wichtigste Ergebnisse werden festgehalten, dass 1) Luftzugaben das Betriebsverhalten der Pumpe verschlechtern; 2) hoehere Systemtemperaturen das Kavitaionsverhalten verbessern; 3) instationaere Versuche zu Hysteresiserscheinungen fuehren; 4) das Betriebsverhalten im untersuchten Bereich gut war.
