Abstract

Die vorliegende Erfindung betrifft eine magnetgekoppelte Kreiselpumpe mit Spalttopfüberwachung. Diese Kreiselpumpe weist einen Spalttopf (1) auf, der eine für ein magnetisches und/oder elektrisches Feld zumindest teilweise durchlässig Trennwand (10) aufweist, um ein im Spalttopf (1) angeordnetes Pumpenrad der Kreiselpumpe berührungslos anzutreiben. Ausserdem weist die Kreiselpumpe einen elektrischen Leiter (20) zur flächenmässigen Überwachung des Spalttopfs (1) auf. Dabei ist der, gegebenenfalls isolierte, elektrische Leiter (20) innerhalb des Wandmaterials der Trennwand (10) oder unmittelbar auf der Oberfläche der Trennwand (10) angeordnet, um die Integrität der Trennwand (10) zu überwachen. Dadurch können Beschädigungen der Trennwand mit einem geringen technischen Aufwand, in einem frühen Stadium und mit hoher Zuverlässigkeit erkannt werden.

Figure imgaf001
The present invention relates to a magnetically coupled centrifugal pump with gap pot monitoring. This centrifugal pump has a containment shell (1), which has a partition (10) which is at least partially permeable to a magnetic and / or electric field, in order to drive a pump impeller of the centrifugal pump arranged in the containment shell (1) without contact. In addition, the centrifugal pump has an electrical conductor (20) for surface monitoring of the containment shell (1). In this case, the optionally insulated electrical conductor (20) is arranged inside the wall material of the dividing wall (10) or directly on the surface of the dividing wall (10) in order to monitor the integrity of the dividing wall (10). As a result, damage to the partition can be detected with little technical effort, at an early stage and with high reliability.
