Abstract

A sewage pump has a shaft with an upward rotor penetrating a dividing ring base at a top end of the combination housing to integrate with a centrifugal switch. Two opposite sides inside the dividing ring base respectively have supporting elements to make a start capacitor and a run capacitor been supported therebetween so that each element within the combination housing on the dividing ring base has optimum orientation and arrangement.

Claims

exact text as granted — not AI-modified
1 . A sewage pump comprising a pump housing, a central rotor and a surrounding stator accommodated in the pump housing, a dividing ring base attached to one end of the pump housing to combine with a start capacitor and a run capacitor;
 improvement of the sewage pump comprises:   the central rotor faces upward and has a shaft penetrating the dividing ring base to integrate with a centrifugal switch.   
   
   
       2 . The sewage pump as claimed in  claim 1 , wherein
 improvement of the sewage pump further comprises:   two supporting elements are attached two sides of the dividing ring base respectively to support the start capacitor and the run capacitor so that each element in the sewage pump has optimum orientation and arrangement.   
   
   
       3 . The sewage pump as claimed in  claim 2 , wherein each of the two supporting elements has a sleeving element being a loop to hold the start capacitor or the run capacitor.
