Description

Tauchpumpenanordnungen sind häufig mit einem Schwimmerschalter ausgerüstet, welcher über ein Kabel mit dem Pumpengehäuse verbunden ist, wobei das Kabel in eine am Gehäuse angeordnete Kabelhalterung eingeklemmt werden kann. Bei sinkendem Wasserpegel neigt sich der Schwimmerschalter nach unten und bricht ab einer vorgegebenen Neigung den Betrieb der Pumpe ab. Bei wieder steigendem Wasserpegel wird der Schwimmerschalter nach oben getragen und neigt sich gegen die Kabelhalterung nach oben, bis ab einem vorgegebenem Neigungswinkel die Pumpe wieder in Betrieb gesetzt wird. Durch die Länge des Kabelabschnitts zwischen Kabelhalterung und Schwimmerschalter kann die der Schalthysterese entsprechende Pegeldifferenz eingestellt werden. Eine derartige Tauchpumpenanordnung mit einem Schwimmerschalter ist beispielsweise aus der EP 420 218 B1 oder der US 4,626,175 A bekannt.Submersible pump assemblies are often equipped with a float switch, which is connected via a cable to the pump housing, wherein the cable in a can be clamped on the housing arranged cable holder.

Das Kabel kann in an sich bekannter Weise klemmend in eine der Aufnahmen eingedrückt werden. In the sketched in Fig. 1 in side view pump assembly is a level SE through the pump housing GE or provided on this, possibly height-adjustable Feet SF or the like determined. Laterally on the housing a profile strip PL is formed, in which at different heights H1, H2 ... separate recordings AU1, AU2 ... for a At the top of the housing, sketched cable KA between the pump and an in Fig. 1, not shown, float switches are formed. The cable can be in itself well-known manner be clamped pressed into one of the recordings.

Die in unterschiedlichen Höhen angeordneten Aufnahmen erlauben eine variable Einstellung der Höhe der Kabelfestlegung am Gehäuse und damit eine Einstellung der Schalthöhen des Schwimmerschalters unabhängig von der Länge des Kabelabschnitts zwischen Aufnahme und Schwimmerschalter. Anstelle mehrerer einzelner Aufnahmen kann auch eine Aufnahme höhenverstellbar sein.The images arranged at different heights allow a variable Adjusting the height of the cable fixing on the housing and thus setting the Switching heights of the float switch regardless of the length of the cable section between recording and float switch.
