Abstract

Hierbei geht es um die Spülung der Laufradspaltringe bzw. Drosselspalten, welche durch die in der Förderflüssig­ keit enthaltenen Feststoffe einem erhöhten Verschleiß aus­ gesetzt sind. Da spezielle Spülpumpen bei den in großen Meerestiefen angeordneten Unterwassermotorpumpen ei­ nen erheblichen zusätzlichen Aufwand darstellen, wurde eine andere Lösung gefunden. Es werden die zu spülenden Stellen von denjenigen Pumpenstufen, deren Druck kleiner als der äußere hydrostatische Druck ist, direkt mit dem umgebenden Meerwasser gespült. This involves flushing the impeller split rings or throttling gaps caused by the in the liquid solids contain increased wear are set. Because special flushing pumps in the large Submersible pumps arranged at sea depths represent significant additional effort found another solution. It will be flushed out Make those pump stages whose pressure is lower than the outside hydrostatic pressure is, directly with that surrounding sea water rinsed.
