Water Pump for Bodies of Water Containing Suspended Particles

Abstract

A water pump for bodies of water such as ponds, aquariums, or fountains containing suspended particles has a housing with a pump housing part provided with an intake opening and an exit opening, in which housing part an impeller with a shaft is rotatably supported, and a motor housing part in which an electric motor is received. As an improvement, an electronically commutated motor is used and the pump has a power input as well as power and control electronics for the motor having an operating state detection device with speed detection, processor and data storage device. The processor can control an interrupt switch between the power input and the motor. In the data storage device certain characteristic lines in regard to normal operating states can be stored.

What is claimed is: 
     
         1 . A water pump for bodies of water containing suspended particles, the water pump comprising:
 a housing comprises a pump housing part provided with an intake opening and an exit opening and further comprising a motor housing part;   an impeller with a shaft arranged in the pump housing part so as to be rotatable;   an electric motor arranged in the motor housing part, wherein the electric motor is an electronically commutated motor;   a power input;   power and control electronics for the electric motor comprising an operating state detection device with speed detection, a processor, and a data storage device.   
     
     
         2 . The water pump according to  claim 1 , further comprising an interrupt switch controlled by the processor and arranged between the power input and the electric motor. 
     
     
         3 . The water pump according to  claim 1 , wherein information in regard to at least one normal operating state of the water pump are stored in the data storage device. 
     
     
         4 . The water pump according to  claim 3 , wherein the information comprises at least one of a pump characteristic line and a speed characteristic line. 
     
     
         5 . The water pump according to  claim 3 , comprising a software that carries out a nominal/actual value comparison between a stored standard operating state data and an actual operating state of the water pump detected by the operating state detection device, wherein the software initiates a change of the actual operating state when a preset difference for the nominal/actual value comparison is surpassed. 
     
     
         6 . The water pump according to  claim 5 , wherein the change of the actual operating state consists of running a predetermined program with speed change of the water pump. 
     
     
         7 . The water pump according to  claim 6 , wherein, when the standard operating state is reached again during the program pass, the program is stopped. 
     
     
         8 . The water pump according to  claim 6 , wherein the change of the actual operating state resides in an activation of an interrupt switch or in ending the program. 
     
     
         9 . The water pump according to  claim 1 , wherein the power and control electronics comprises governing electronics governing a predetermined speed. 
     
     
         10 . The water pump according to  claim 1 , wherein the power and control electronics are arranged in the motor housing part and are water-tightly potted.
