Sewage pump

1. Field of the Invention

The present invention relates to a sewage pump, and more particularly to a sewage pump that has a shaft with an upward rotor penetrating a dividing ring base on a top end of a combination housing to integrate with a centrifugal switch and has two supporting elements respectively attached to two opposite sides inside the dividing ring base to support a start capacitor and a rung capacitor therebetween so that each element has optimum orientation and arrangement.

2. Description of Related Art

A conventional sewage pump in accordance with the prior art, as shown in FIG. 1, its combination comprises a pump housing 10 having rotor at center and a cylindrical stator surrounding around the rotor (not shown). One end of the pump housing 10 combines with a dividing ring base 20 to assemble a start capacitor 30 and a run capacitor 40 thereon. Moreover, upper and lower ends are further combined with relative accessories to achieve the sewage pump combination to provide power for treating sewage. After, the conventional sewage pump has some drawbacks needed to be resolved such as the start capacitor 30 is easily burned and has short lifespan because it is suspended in ON operation.

One main objective of the present invention is to provide a sewage pump that 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.

Another main objective of the present invention is to provide a sewage pump that further has two supporting elements respectively attached to two opposite sides within the dividing ring base to support a start capacitor and a run capacitor therebetween so that each element in the sewage pump has optimum orientation and arrangement.

To achieve the foregoing objectives, the sewage pump comprises 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;

improvements of the sewage pump comprise:

the central rotor faces upward and has a shaft penetrating the dividing ring base to integrate with a centrifugal switch;

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.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
