Described stiffening rib is distributed on the pump housing excircle.The design that stiffening rib is uniform makes that the intensity of the pump housing is better.
Described stiffening rib extends to the whole pump housing vertically.The length of stiffening rib is identical with the pump housing, then makes intensity better.
Described stiffening rib number is less than or equals the number of stator iron core notch.Preferred version is: the stiffening rib number is identical with the notch number, and with maximum numbers, intensity is better like this.
The sectional shape of described stiffening rib is rectangle, trapezoidal, triangle, zigzag fashion or semicircle.The shape of stiffening rib also can be other shape, as long as after assembling, can guarantee to stretch into smoothly the stator iron core notch and get final product.
The described pump housing is a plastic material.Plastic material is that cost is lower, more easily obtains, and intensity again can satisfactory material simultaneously.
The rated output power scope of described water pump is 10-60W.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is provided for the water pump of draining or water cycle, because pump housing excircle is provided with and corresponding several stiffening ribs of stator iron core notch, make the intensity of the pump housing strengthen greatly, can suitably reduce the thickness of the pump housing like this, thereby can reduce the air gap of interior circle of stator and rotor cylindrical, improve efficiency of motor, finally improved the efficient of water pump.
