| titleOfInvention | Multistage centrifugal pump stator rotation-proof structure |
| abstract | The invention discloses an anti-rotation structure for guide vanes of a multistage centrifugal pump, which comprises a water inlet section, multistage guide vanes, a middle section, a water outlet section and a pin, wherein the water inlet section, the guide vanes and the middle section are sequentially connected through the pin; the outer diameter of the front cover plate of each stage of guide vane is increased to be the same as the outer diameters of the middle section, the water inlet section and the water outlet section; the contact parts of the water inlet section and the water outlet section with the edge of the front cover plate of the guide vane are respectively provided with a pin hole; the contact surface of the middle section and the inner side of the front cover plate of the front guide vane of the previous stage is provided with pin holes with the same number as that of water inlet sections, and the contact surface of the middle section and the outer side of the front cover plate of the guide vane of the next stage is provided with pin holes with the same number as that of water outlet sections; the edge of the front cover plate of each stage of guide vane is provided with pin through holes with the same quantity as the water inlet section and the water outlet section. The anti-rotation structure can improve the stability of the guide vane, so that the guide vane is firmly fixed, and the service life of the multistage centrifugal pump is prolonged. |
