Example Embodiment
[0017] Such as figure 1 , A centrifugal water pump, comprising a pump housing 1 and a pump shaft 2 that is rotatable at both ends of the pump housing through a bearing. One end of the pump shaft extends outside the pump housing, and a connecting part connecting the power input device is installed on the extension section, The connecting part can be a flange 3, such as figure 1 . The pump casing 1 is divided into two connected front and rear sections. The front section is the pump volute 11 and the rear section is the segmented pump casing 12; an eccentric rotor 4 with fixed blades is installed in the pump volute; and the segmented pump casing is installed The semi-open tangent impeller 5, the blades of the semi-open tangent impeller have a radial structure to the center of rotation, such as image 3 , Figure 4 .
[0018] In order to improve the operating efficiency of the impeller and reduce the flow resistance, the impeller can be rotated 15° in the tangential direction, such ...
