Embodiment 1
[0026] like figure 1 A schematic structural diagram of the low-vibration swirl pump volute provided by the present invention is illustrated.
[0027] exist figure 1 , the frontal section of the structure of the low-vibration swirl pump volute is provided, and the swirl pump volute may include: a front pump body 11 and a retraction cavity 12 , the front pump body 11 and the retraction cavity 12 are integrated structure; a groove is provided on the inner wall surface of the retraction cavity 12, and the wall surface of the retraction cavity 12 has an inclination angle θ compared to the axis of the volute of the swirl pump;
[0028] The front pump body 11 is used to reduce the speed of liquid flow, so that the speed corresponding to the speed can be converted into pressure energy;
[0029] The setback cavity 12 is used for placing the impeller 3 , increasing the axial distance between the impeller 3 and the inlet of the setback cavity 12 .
[0030] Optionally, V-shaped grooves...
